mid-mount cutting capability for professional landscapers, commercial lawn service compa-  
nies, professional turf managers and golf course superintendents. The machine incorporates  
many safety features that should be studied by all operators and maintenance personnel  
before use. The list of safety precautions should receive particular attention.  
This manual presents all of the operating and maintenance instructions necessary to keep  
your mower at peak efficiency. If operated and maintained properly, your mower will give  
dependable service.  
CAUTION:  
Only thoroughly trained persons should operate and maintain this  
mower. This machine can cause serious injury to anyone who mis-  
uses it and does not understand its operation. For their personal  
safety, all operators and maintenance personnel are required to  
read this entire manual before operating the mower.  
Hazard control and accident prevention are partially dependent  
upon the design and configuration of the equipment. Notwithstand-  
ing, these factors are also dependent upon the awareness, concern,  
prudence and proper training of the personnel involved in the oper-  
ation, transport, maintenance and storage of the equipment.  
WARNING  
The engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals  
known to the State of California to cause cancer, birth defects or other reproductive harm.  
This unit is equipped with an internal combustion engine and should not be used on or near any unim-  
proved forest-covered, brush-covered, or grass-covered land unless the engine’s exhaust system is  
equipped with a spark arrester meeting applicable local or state laws (if any). If a spark arrester is used, it  
should be maintained in effective working order by the operator.  
In the State of California, the above is required by law (Section 4442 of the California Public Resources  
Code). Other States may have similar laws. Federal laws apply to federal lands. A spark arrester muffler  
may be available.  
NOTE: The engine manufacturer is responsible for all engine-related issues with  
regards to performance, power-rating, specifications, warranty and  
service. Please refer to the engine manufacturer’s owner’s/operator’s  
manual, packed seperately with your unit, for more information.

4. Do not remove any shields, guards or safety  
devices. If a shield, guard or safety device is  
damaged or does not function, repair or  
replace it before operating the mower.  
5. Always wear safety glasses and safety shoes  
when operating or maintaining this mower. Do  
not wear loose-fitting clothing.  
8. Do not operate machines on slopes when  
traction is reduced (wet grass, ice, soft  
ground, loose ground, leaves, pine needles,  
debris, etc.).  
9. Avoid turning downhill if possible, go slowly  
and use extra care when turning downhill.  
10. Do not operate machines during reduce visi-  
bility (low light, fog, rain, etc.).  
11. Do not operate machines with non-approved  
attachments.  
12. Do not operate machines that are dam-  
aged.....have machine repaired.  
13. Do not operate machines that have not been  
properly maintained.  
6. Disconnect the spark plug wires and remove  
the key from the ignition to prevent the engine  
from accidentally starting before performing  
any maintenance on this mower.  
7. Never run the engine indoors without ade-  
quate ventilation. Exhaust fumes are deadly.  
8. To avoid serious burns, do not touch the  
engine, exhaust pipe or muffler while the  
engine is running or until it has cooled after it  
has been shut off.  
14. Use only replacement parts that are the same  
or equivalent to the original equipment.  
15. Do not modify machines or any of their com-  
ponents, especially the engine governor!  
16. Do not operate machine for more than 2 hours  
without hearing protection.  
C. CAUTION  
1. Use proper protective equipment when oper-  
ating machine (gloves, boots, and hearing  
protection are recommended).  
2. Read entire machine Operator’s Manual.  
3. Make sure operators are fully trained in the  
safe use of the machine.  
9. The liquid in the battery is dilute sulfuric acid.  
Always wear safety glasses and rubber gloves  
when working on the battery. Do not overfill  
the battery.  
4. Follow all safety instructions when using the  
machine.  
10. Lead-acid batteries generate hydrogen and  
oxygen gases which form an explosive mix-

ture. Keep sparks and flames away at all  
times.  
terminals can produce sparks and heat...connections  
to the terminals must be kept tight, and the terminals  
and battery surfaces kept clean of acids and corro-  
sion. If batteries are re-charged or “jumped” from  
external sources, make sure that the connections are  
made properly and in the correct sequence...connect  
to the positive terminal of the good battery first, then  
connect that to the positive terminal of the weak bat-  
tery. The third connection should be to the negative  
terminal of the good battery, followed by the negative  
terminal of the weak battery. If sparks are observed  
or heating of the wiring or connectors is detected,  
disconnect in reverse order (I.E., the negative termi-  
nal of the weak battery first). Batteries should be re-  
charged at a constant voltage...generally 14.5 +/- 0.5  
volts DC for a nominal 12 volt DC battery.  
11. When looking for oil leaks, never run your  
hand over hydraulic hoses, lines or fittings.  
Never tighten or adjust hydraulic hoses, lines  
or fittings while the system is under pressure.  
If high-pressure oil penetrates the skin, the oil  
must be removed within a few hours by a doc-  
tor familiar with this form of injury or serious  
complications may result.  
B. Related to Fuel  
1. Fuel is highly flammable and its vapors can  
explode if ignited. Please respect it.  
2. Do not smoke or permit others to smoke  
while handling fuel.  
3. Always use approved containers for fuel and  
fill slowly to decrease the chance of static  
electricity buildup and spillage.  
4. Store fuel in well ventilated and unoccupied  
buildings away from sparks and flames.  
5. When dispensing gasoline into approved con-  
tainers, place the container on the ground  
when refueling to avoid a possible static elec-  
tricity ignition of fuel vapors.  
6. Do not fill containers while it is inside a vehi-  
cle, trunk, the bed of a pickup or floor of a  
trailer.  
7. Always shut off the engine and permit it to  
cool before removing the fuel tank cap.  
8. Always fill the fuel tank outdoors.  
9. If the fuel container spout will not fit inside the  
fuel tank opening, use a funnel.  
D. When Mowing  
1. Keep adults, children and pets away from the  
area to be mowed.  
2. When operating this mower in the forward  
direction, DO NOT allow the steering levers to  
return to the neutral position on their own.  
Always maintain a firm grip on the levers,  
operate them smoothly and avoid any sudden  
movements of the levers when starting or  
stopping.  
3. If the mower is equipped for side discharge,  
never use the mower without the discharge  
chute installed and placed in the down position.  
4. Always remove debris and other objects from  
the area to be mowed.(Note: debris and loose  
grass will reduce traction.)  
10. When filling the fuel tank, stop when the fuel  
reaches one inch from the top. This space is

6. Watch for holes, sprinkler heads and other  
hidden hazards.  
necessary for tank expansion. Do not overfill  
.
11. Wipe up any spilled fuel.  
7. Avoid driving too close to trees, creeks,  
ditches, sand traps and other obstacles.  
8. Before backing up, check behind you and  
watch where you’re going.  
9. Always reduce speed when making a turn,  
and when grass is wet.  
C. Related to Batteries  
Batteries are stored electrical energy devices that  
may be serviceable with removable caps (the electro-  
lyte levels can be checked), or may be non-service-  
able (no attempt should be made to open the vents).  
10. Always mow across slopes, never up and  
down the slope. Do not operate on steep  
slopes and slow down before turning.  
11. Be careful when crossing gravel paths or  
roadways. Always turn off the blade clutch  
switch and wait until the blades stop rotating  
and raise the cutting deck to the transport  
position. Always allow other vehicles to have  
the right-of-way.  
12. If you hit a solid object while mowing, turn off  
the blade clutch switch, place the left and right  
steering levers in the neutral, opened-out  
position, move the throttle to slow, set the  
parking brake, shut off the engine and take  
the key from the ignition switch. Inspect for  
Batteries may contain lead (Pb) and sulfuric acid,  
and they must be re-cycled and not disposed of nor  
abandoned. Sulfuric acid can cause severe burns,  
and in the event of contact, the areas should be  
flushed with water and a physician contacted. Bat-  
tery cases should not be punctured. Lead is poison-  
ous and is contained within the positive and negative  
terminals as well as within the battery’s internal grid-  
work of plates and active materials.  
Explosive gases are generated when batteries are  
re-charged, so sparks, flames and heat sources  
should be avoided. Loose connections at the battery

damage. Repair any damage. Make sure the  
blades are in good condition and that the  
blade bolts are tight before restarting the  
engine.  
13. Never leave the mower unattended without:  
turning off the blade clutch switch; placing the  
left and right steering levers in the neutral  
opened-out position; moving the throttle to  
slow; setting the parking brake; shutting off  
the engine and taking the key from the ignition  
switch.  
14. Never walk or stand on the discharge side of a  
mower with the engine running. Turn off the  
blade clutch switch if another person  
approaches while you are operating the  
mower.  
15. Never attempt to operate the traction unit  
without the mowing deck attached.  
16. Keep the mower and especially the engine  
and hydraulic components clean and free of  
grease, grass and leaves to reduce the  
chance of fire and to permit proper cooling.  
E. Towing  
1. Tow only with a machine that has an approved  
hitch designed for towing. Do not attach towed  
equipment except at the hitch point.  
2. Follow the manufacturers recommendation for  
weight limits for towed equipment and towing  
on slopes.  
3. Never allow children or others in or on towed  
equipment.  
4. On slopes, the weight of the towed equipment  
may cause loss of traction and loss of control.  
Note: 5 degrees (9%) maximum slope.  
5. Travel slowly and allow extra distance to stop.

A.General  
1. When Mowing:  
a. Keep adults, children, and pets away from  
the area to be mowed.  
b. When operating this mower, in the forward  
direction, do not allow the steering levers  
to return to Neutral on their own. Always  
maintain a firm grip on the levers, operate  
them smoothly and avoid any sudden  
movements of the levers when starting and  
stopping.  
c. If the mower is equipped for side dis-  
charge, never use the mower without the  
discharge chute installed and placed in the  
down position.  
d. Always remove debris and other objects  
from the area to be mowed (Note: debris  
and loose grass will reduce traction).  
e. Mow only in daylight.  
f. Watch for holes, sprinkler heads, and other  
hidden hazards.  
g. Avoid driving too close to trees, creeks,  
ditches, sand traps, and other obstacles.  
h. Before backing up, check behind and  
watch where you are going.  
i. Always reduce speed when making a turn,  
and when grass is wet.  
j. Always mow across slopes, never up and  
down the slope. Do not operate on steep  
slopes and slow down before turning.  
Avoid turning downhill if possible, start at  
the bottom and work up to the top. Use  
extra care and go slowly when turning  
downhill. Control the speed and direction  
of the zero turn machine “primarily” with  
the speed/directional control (lap bar) of  
the downhill side of the machine...I.E.,  
maintain the uphill side lap bar “essen-  
tially” in a fixed position.  
o. Never attempt to operate the traction unit  
without having the mowing deck attached.  
p. Keep the mower and especially the engine  
and hydraulic components clean and free  
of grease, grass, and leaves to reduce the  
chance of fire and permit proper cooling.  
2. Safety Awareness when Mowing  
a. Do not operate on steep slopes, those  
above 15 degrees (27% slope).  
b. Avoid turning downhill if possible, if not use  
extra care and go slowly.  
c. Avoid turning when going downhill, traction  
is at a minimum going downhill.

d. Do not operate with discharge side of the  
mower toward streets, buildings, play-  
grounds, parking lots, other machines, ani-  
mals, and other people.  
e. Avoid operation or use extreme care if the  
traction surface is wet, unstable, or slip-  
pery.  
f. Use extra care when grass clippings,  
leaves, pine needles, or debris are present  
as traction can be reduced.  
switch in the “on” position until the glow-plug  
light goes out. Turning the switch further  
against spring pressure starts the engine.  
The engine will only start if the blade clutch  
switch is in the “off” position, the parking  
brake is engaged and the left and right steer-  
ing levers are in the neutral, opened-out  
position. The key should always be removed  
from the switch if the operator leaves the  
mower’s seat.  
g. Slow-down before turning and come to a  
complete stop before any zero turn maneu-  
ver.  
h. Do not stop machine or park machine over  
combustible materials such as dry grass,  
leaves, debris, etc.

2. Glow Plugs: Combustion chamber plugs are  
fitted with the necessary precise tip protrusion  
into each combustion chamber, to enable the  
sprayed fuel to be properly ignited during  
cranking, without causing a significant drop of

Glow plugs, due to their high tip temperature  
when activated, give satisfactory starting at

area to be mowed (post, tree, shrub, etc.).  
3. Engine Throttle Control: (See Figure 2.)  
Located on the left side of the mower next to  
the operator’s seat. Moving the throttle control  
from the rear to the front will increase the  
engine speed from slow to fast.  
b. If on an hillside, start at the bottom so that  
the turns are uphill rather than downhill.  
c. Align the mower so as to head directly  
toward the object on the far side.  
d. Slowly increase the speed of the machine  
to match cutting conditions, terrain, and  
operator familiarity with the controls and  
keep the machine headed directly toward  
the alignment object. Do not go fast as to  
reduce cut quality or to be uncomfortable  
in controlling the speed and direction of the  
machine.  
e. When approaching the other end of a strip,  
slow down or stop before turning. A U-turn  
is recommended unless a zero turn is  
required. The speed of a U-turn that will  
allow for machine controllability and mini-  
mal turf defacement will be dependent on  
several factors including: the speed of the  
turn, the radius of the turn, the tire tread  
pattern, the traction coefficient of the tire to  
the traction surface, the slope of the trac-  
tion surface.  
4. Left and Right Steering Levers: (See Figure  
3.) These hinged levers open out to the side  
in the neutral position to permit the operator to  
be seated or to leave the mower’s seat. The  
operator, when seated, can pull the levers up  
to the operating position, a comfortable fore-  
arm’s length away. These levers control all of  
the movements of the mower. Pushing both  
levers forward causes the mower to move for-  
ward. Pulling both levers back causes the  
mower to move backward. Pushing one lever  
ahead of the other lever causes the traction  
wheel on the side where the lever is ahead to  
rotate faster than the other traction wheel,  
making the mower turn toward the side where  
the lever is behind. When one lever is pushed  
forward and the other lever pulled back the  
same amount, one traction wheel will turn in  
reverse and the mower will turn within its own  
length.  
f. Remember, a zero turn requires that the  
forward or reverse travel of the machine be  
stopped prior to the initiation of the turn or  
severe turf defacement can occur.  
g. To prevent rutting or grooving of the turf,  
change the direction that the strips are  
mowed by approximately 45 degrees the  
next and each subsequent time that the  
area is mowed.  
In order to start the engine, both steering  
levers must be opened out to the side in the  
neutral position; the parking brake must be  
engaged; and the blade clutch switch must be  
“off”. However, once the engine starts, the  
parking brake must be released before the  
operator places the steering levers into the  
operating position or the engine will  
automatically shut off.  
B.Controls  
1. Engine ignition and start switch: (See Fig-  
ure 1.) Located on the instrument housing  
below the right side of the operator’s seat.

position so the hole in the pedal aligns with  
the hole in the lever. Reinstall the detent pin.  
This is the required position for the foot pedal  
for the foot platform to tilt forward and to  
access some of the machines components.  
8. Fuel Shutoff Valve: (See Figure 4.) Located  
behind the operator’s seat, the valve has  
three (3) positions: “off”, “Left Tank”, “Right  
Tank”. Close this valve if you are not going to  
run the mower for a period of 30 minutes or  
more to prevent flooding the engine. The fuel  
system operates under pressure when the  
engine is running.  
5. Electric Blade Clutch Switch: (See Figure  
1.) Located on the right side of the mower  
beside the ignition switch. This is an “on/off”  
push pull switch that controls the electric  
blade clutch which supplies power to the cut-  
ting blades through the PTO. The switch must  
be turned off to start the engine and should  
be turned off for safety any time another per-  
son approaches the mower or the mowing  
deck is raised to the transport position. Power  
to the electric clutch will also be cut off if the  
operator leaves the operator’s seat.  
6. Parking Brake: (See Figure 3.) Located on  
the left side of the traction unit. The handle is  
an overcenter lever which applies the drum-  
type brake on each drive wheel when the han-  
dle is pulled to the rear. The brake must be  
engaged in order to start the engine.  
Note: In the left tank position, fuel will be  
drawn from the left tank only, and excess fuel  
not consumed by the engine will be returned  
to the left tank. This also applies to the right  
tank.  
9. Seat Adjustment Lever: The Seat Adjust-  
ment Lever is located beneath the seat. The  
Seat Adjustment Lever is used to move the  
seat forward and backward. To place the seat  
in the desired position pull the seat adjust-  
ment lever to the left then push the seat for-  
ward or back to the desired position. Release  
the lever so the seat will lock in place. The  
lever on the side allows a choice of four seat  
back angles, plus a folded-down position.  
Knobs in each armresr allow them to be  
adjusted to the desired height.  
10. Hourmeter (Digital Tachometer Optional):  
(See Figure 1 on page 9) Located on the right  
side of the mower in front of the ignition  
switch. When the machine is running the  
tachometer displays engine rpm. When the  
machine is off the tachometer displays run-  
ning time.  
7. Deck Lift Handle and Foot Pedal Lift  
Assist: (See Figure 3.) Located on the right  
front corner of the mowing deck. Raise the  
mowing deck to the transport position, by pull-  
ing the lever to the rear and moving it inward  
into the stop for transport. To lower the mow-  
ing deck, pull the deck lift handle and move it  
outward. This lower’s the deck to the cutting  
position.The foot pedal lift assist (not pictured  
above) can provide “lift assist” to the hand  
lever or with “foot effort only”. To provide  
assistance to the lift handle: remove the  
detent pin from the pedal assembly. Fold the  
pedal down to the horizontal position so the  
hole in the pedal aligns with the hole in the  
lever. Re-install the detent pin. Pull on the Lift  
handle and depress the foot pedal to raise the  
deck. Lifting with “foot effort only” depress the  
foot pedal (the hand lever will lock into trans-  
port position if fully depressed). To release the  
lift mechanism depress the foot pedal, move  
the hand lever outward and slowly reduce foot  
pedal effort to lower the mechanism. To ser-  
vice the unit: Remove the detent pin from the  
pedal assembly. Fold the pedal up to vertical

the procedures below to set the appropriate  
angle to the mowing deck.  
C.Initial Adjustments  
1. Check the fluid levels and tires:  
a. Park the mower on a flat paved surface,  
engage the parking brake, shut off the  
engine, remove the key from the ignition  
switch, remove connection of the spark  
plugs and using the transport lever, lower  
the mowing deck into the cutting position.  
b. Using a ruler, pencil and paper, measure  
and note the distance from the paved sur-  
face to the bottom edge of the mowing  
blade at the front and the back of the deck  
on each side of the mower. (Four dimen-  
sions.)  
Note:These checks should be made daily,  
before starting the engine.  
a. Fuel: Using a good grade of #2 Diesel fuel,  
fill the fuel tank (beside the engine on the  
left or right side of the mower). When the  
fuel reaches one inch from the top of the  
tank, stop. DO NOT OVERFILL. Space  
must be left for expansion. (see page 29  
for more specs.)  
b. Engine Oil: (Filled at the factory before  
shipment.) Pull out the oil dipstick, wipe it  
off and reinsert it. Pull it out again and read  
the oil level. If it is below the operating  
range, add oil through the fill tube using a  
funnel to bring it up to the top of the operat-  
ing range. (see page 29 for more specs.)  
Note:The front edge of the mowing deck  
should be 1/8"-1/4" below the rear edge of the  
deck so that the blades are cutting grass in  
only the front half of their circular path. This  
decreases friction and reduces the drive  
power required.  
Note:Shell Rimula 15W40 is recommended  
and provides service SL and CI-4 plus.  
c. If the dimension at the front of the mowing  
deck is 1/8"-1/4" lower than the dimension  
at the rear of the deck on each side of the  
mower, do not adjust. If not, you will need  
to adjust the Deck Lift Spring Assist (See  
Figure 5). You may also need to adjust the  
Deck Links (See Figure 5).  
c. Engine Coolant: Use Shell Dex-cool,  
extended life anti-freeze diluted with water  
to create a 50:50 mixture.  
d. Hydraulic Oil: (Filled at the factory before  
shipment.) The hydraulic oil tank is located  
beneath the operator’s seat. Always wipe  
off the area around the oil tank fill neck  
before checking the oil level to prevent dirt  
from contaminating the oil. Remove the  
cap and make sure the oil level is 1/4”  
below the oil tank fill neck. If the oil level is  
low, fill with Shell Rimula 15w40 or equiva-  
lent oil. Equivalent oil should meet GM Alli-  
son C-4.  
Deck Lift Spring inner nut  
e. Tires: 10-12 psi Rear, 20-25 psi Front  
Caster Tires  
Note:New tires are overinflated in order to  
Deck Links  
properly seat the bead to the rim. The normal  
working pressure for the traction tires is 10-12  
psi. The front caster wheels should be inflated  
to 20-25 psi.  
Figure. 5  
d. Lower the mower deck to the cutting posi-  
tion. With a wrench loosen the inner rear  
nut on the Deck Lift Spring Assist. To  
adjust the deck up or down, use a wrench  
and with a few turns, adjust clockwise or  
counter clockwise the outer rear nut of the  
Deck Lift Spring Assist. Repeat this proce-  
dure on the opposite side of the Mower.  
Once the deck is adjusted, retighten bolts.  
e. With the deck still in the cutting position,  
adjust the Deck Links. With a wrench  
loosen the top inner bolt of the Deck Link.  
To adjust the side of the deck up or down  
turn the top bolt clockwise or counter  
clockwise a few turns. Adjust both front  
and rear Deck links as necessary.  
2. Check that all Nuts, Bolts and Screws are  
Tight.  
3. Check the tension of the deck drive belts.  
a. Remove the deck cover  
b. The tension of the deck drive belts are  
maintained by a spring mechanism that  
adjusts for wear and stretch.  
c. Examine the belts for cuts, fraying, and  
excessive wear. Replace if any of these  
are detected.  
d. Replace the deck cover.  
4. Adjust the Mowing Deck: The cutting height  
is set anywhere in the range of 1-1/2" to 5".  
You may need to adjust the mowing deck to  
achieve the proper angle for mowing. Follow  
Retighten nuts.  
12

f. Raise the mowing deck to the transport  
position using the transport lever.  
2. That there are no spilled or leaking fuel  
or oil sources, nor loose fuel or hydraulic  
tank caps, hoses or fittings.  
3. That there are no loose or missing hard-  
ware nor any missing items.  
4. That no non-approved devices are  
installed.  
5. That all safety signs and decals are  
properly installed and legible.  
g. Use the transport lever to lower the mow-  
ing deck to the cutting position and repeat  
step “b.above to make sure that the  
desired cutting height has been attained. If  
the dimensions are not correct, repeat  
steps “c.through “f.above.  
5. Lubricate all fittings listed in the mainte-  
nance section.  
e. This is a one person machine, operator  
only! Riders are not permitted under any  
circumstance!  
f. To start the engine on the machine:  
1. Make sure the park brake is set to the  
“ON” position, both lap bars are in the  
neutral/start (opened-out) position, and  
the Power Take Off (PTO also referred to  
as blade control switch) is in the “off”  
(down) position.  
2. Move the engine speed control (throttle)  
forward (half way).  
3. Insert the key in the ignition and start  
switch, turn the switch to “On”, and wait  
for the glo-plug light to go out.  
D. Zero Turn Break-In And Operating  
Procedures  
DANGER:  
Reread the “When Mowing” Safety Precautions.  
The following procedures are suggested for opera-  
tors of ride-on machines which have zero turn  
capabilities.  
1. Orientation:  
a. Read the entire Operator’s Manual.  
b. Sit on the machine, adjust the seat before-  
and-after, then adjust the speed/directional  
(lap bar) controls (they can be adjusted  
fore & aft, as well as up & down — 9/16"  
wrench required).  
4. Turn the ignition key in a clockwise direc-  
tion to the “Start” position until the  
engine starts.  
g. Check safety devices:  
c. Become familiar with all of the machine  
controls, instrumentation, safety and  
instruction signs, and safety devices.  
d. Move (or have moved) the machine to a  
safe, level area with no obstructions includ-  
ing objects, pedestrians, and animals.  
2. Initial Operation:  
a. Use protective equipment for eyes, hands,  
hearing, feet, legs, head and other areas of  
the body if needed — safety eye glasses,  
gloves, earplugs, boots, hats, etc.  
1. With the park brake engaged, move one  
of the lap bars (speed/directional control)  
from the neutral/start position to the neu-  
tral position (out of the slot, toward the  
center of the machine) — the engine  
should stop running. Move the lap bars  
back to the neutral/start position and the  
engine should run.  
2. Repeat this procedure with the opposite  
side lap bars.  
3. With the park brake engaged and the lap  
bars in the neutral/start position,  
advance the engine speed control com-  
pletely forward (Hi-idle), engage the PTO  
control switch (pull upward), then lift off  
the seat — the engine should stop run-  
ning. Sit down and the engine should  
run. Turn off the PTO by pushing the  
control switch down.  
h. To drive in the FORWARD direction:  
1. Set the engine speed to 2000 to 2500  
rpm (refer to tachometer on right control  
panel). This must be increased to full  
speed (3525-3675 rpm) after becoming  
familiar with the machine.  
WARNING:  
Hearing Protection is required for all operator  
exposure exceeding two (2) hours.  
b. Ensure that the area is free of animals and  
bystanders, especially children!  
c. Survey the area where the equipment is to  
be used to make sure it is free of debris,  
sticks, stones, wires, bones, and other for-  
eign objects which could cause injury to  
bystanders, damage to the machine, or  
damage to nearby facilities. Also make  
sure that the area is free of toys, stakes,  
pipes, chain, cable, potholes, drop-offs,  
and step slopes.  
d. Inspect the machine to make sure:  
1. All guards, shields (including mower  
chute deflector) are in their proper place,  
are secure, and are functional.  
2. Release the park brake.  
3. Move both lap bars out of the neutral/  
start position to the neutral position  
(toward center of machine). Slowly,  
move both lap bars toward the front of  
the machine until the machine begins to  
13  
Download from Www.Somanuals.com. All Manuals Search And Download.  
move forward — release the lap bars  
and the machine should stop. The more  
that the lap bars are moved toward the  
front of the machine, the faster the  
machine will move in the forward direc-  
tion. Release the lap bars and the  
machine should stop traveling forward.  
(This is a safety check, the normal pro-  
cedure is for the operator to slowly bring  
the lap bars to the neutral position).  
4. Do not advance the lap bars rapidly as  
this could cause turf defacement, loss of  
traction, and/or instability.  
5. To turn, advance one lap bar ahead of  
the other and the machine will turn  
toward the opposite from the side that  
was advanced — I.E. to turn clockwise  
(to the Right), move the LEFT lap bar for-  
ward more than the right side, and to  
turn counter-clockwise (to the LEFT),  
move the RIGHT lap bar forward more  
than the left side. NOTE: If one lap bar is  
in the neutral position and the other is  
advanced, the turn side tire will not  
rotate and a “pivot turn” will be executed  
— turf defacement could occur (if on  
grass) as well as potential damages to  
the traction surface and the tire. If the lap  
bar on the turn side is not brought all the  
way to neutral, then the turn side tire will  
continue to rotate and a “U-turn” will be  
executed with a low potential for turf  
defacement as well as traction surface  
and tire damage.  
than the right side, and to turn clockwise  
(to the RIGHT), move the RIGHT lap bar  
rearward more than the left side. NOTE:  
If one lap bar is in the neutral position  
and the other is retarded, the turn side  
tire will not rotate and a “pivot turn” will  
be executed. Turf defacement could  
occur (if on grass) as well as potential  
damages to the traction surface and the  
tire. If the lap bar on the turn side is not  
brought all the way to neutral, then the  
turn side tire will continue to rotate and a  
“U-turn” will be executed with a low  
potential for turf defacement as well as  
traction surface and tire damage.  
j. To perform a “zero turn”:  
1. Please note, a zero turn maneuver can  
not be executed while the machine is  
moving in the Forward or, Reverse direc-  
tions, the machine must come to a stop  
first.  
2. To turn clockwise, slowly move the LEFT  
lap bar forward while simultaneously  
moving the RIGHT lap bar rearward.  
Release both lap bars and the machine  
should stop turning.  
3. To turn counter-clockwise, slowly move  
the RIGHT lap bar forward while simulta-  
neously moving the LEFT lap bar rear-  
ward. Release both lap bars and the  
machine should stop turning (this is a  
safety check, the normal procedure is for  
the operator to slowly bring the lap bars  
to the neutral position).  
i. To drive in the REVERSE direction:  
1. Make sure no bystanders, animals, or  
objects are behind the machine. Look  
behind the machine, and use extreme  
care.  
3. Start the Engine:  
a. Open the fuel shutoff valve by selecting the  
left or right tank position.  
b. Sit on the Seat. Set the parking brake  
“On”.  
2. Slowly, move both lap bars toward the  
rear of the machine until the machine  
begins to move rearward. Release the  
lap bars and the machine should stop.  
The more the lap bars are moved toward  
the rear of the machine, the faster the  
machine will move in the reverse direc-  
tion. Release the lap bars and the  
machine should stop traveling in reverse  
(this is a safety check, the normal proce-  
dure is for the operator to slowly bring  
the lap bars to the neutral position).  
3. Do not retard the lap bars rapidly as this  
could cause turf defacement and/or loss  
of traction.  
c. Move the left and right steering levers to  
the neutral, opened-out position.  
d. Turn the electric blade clutch switch “Off”.  
e. Push the throttle control to a position a  
third of the way between slow and fast.  
f. Insert the key in the ignition and start  
switch, turn the switch to “On”, and wait for  
the glo-plug light to go out.  
g. Turn the ignition key in a clockwise direc-  
tion to the “Start” position until the engine  
starts.  
Note:Do not hold the key in the “Start”  
position for more than 10 seconds or you may  
damage the starter. If the engine does not start  
in this time, wait about 30 seconds and try  
again.  
4. To turn, retard one lap bar ahead of the  
other and the machine will turn toward  
the same side that was retarded — I.E.,  
to turn counter-clockwise (to the LEFT),  
move the LEFT lap bar rearward more  
4. Operating the Mower: Operating a zero-turn-  
ing-radius mower is not like operating a trac-  
tor-type riding mower. The zero-turning-radius  
14

mower is much more maneuverable and  
much less fatiguing to operate. However, get-  
ting used to the fingertip control of the zero-  
turning-radius mower takes some practice.  
We strongly recommend that you locate a  
“test area” where you can operate the mower  
for about 30 minutes without being disturbed.  
a. Get into the operator’s seat.  
e. Place the steering levers in the neutral  
position.  
f. Set the parking brake.  
g. Turn off the ignition switch and take the key  
from the switch.  
h. Close the fuel shutoff valves.  
E.Mower Cutting Blades  
b. Start the engine.  
The blades normally “factory installed” on a mower  
afford the best grass cutting performance on the  
majority of grasses and mowing conditions; however,  
there will be occasions whereby the grass type,  
stage of grass growth, soil conditions, and weather  
conditions will require different cutting blade types.  
Since the mower decks are designed so that over-lap  
of the cutting blades generally exceed 1.5”, there is  
no need for orientation of one cutting blade to an  
adjacent blade (I.E., the blades do not need to be  
“timed” nor synchronized).  
c. Use the transport lever to raise the mowing  
deck to the transport position. Make sure  
the blade clutch switch is off.  
d. After the engine has warmed, adjust the  
throttle to the fast position.  
e. Release the parking brake.  
f. Fold in the steering levers to the operating  
position.  
WARNING:  
Hi-lift- These are generally the best cutting blades  
for most grasses and mowing conditions. These  
blades will provide extra “lift” for the thinner leaf  
grasses, will handle lush grasses, and will provide  
maximum grass and debris discharge. These blades  
are generally required for material collection sys-  
tems. More horsepower is required for these blades  
when compared to others, and they generally pro-  
duce the highest noise levels.  
When operating this mower forward, do not  
allow the steering levers to return to the neu-  
tral position on their own. Always maintain a  
firm grip on the steering levers, operate them  
smoothly and avoid any sudden movements of  
the levers when starting or stopping.  
g. To go forward, move both steering levers  
slightly forward and the mower will slowly  
move forward. The farther you move the  
levers forward the faster the mower will go  
forward.  
Medium-lift- These blades require less horsepower  
than the hi-lift, and they generally work well in wider  
leaf grasses and some mulch applications.  
h. To back up, move both steering levers  
slightly backward and the mower will  
slowly move backward. The farther you  
move the levers backward the faster the  
mower will go backward.  
i. To turn, pull the lever back on the side to  
which you want to turn. The farther back  
you pull the lever, the faster and more  
sharply you will turn. Initially, you will have  
to be careful to avoid turning to fast and  
too far.  
j. After you have mastered operating the  
mower, use the transport lever to lower the  
mowing deck to the cutting position and  
pull on the electric blade clutch switch to  
start the blades rotating.  
k. Practice mowing in straight passes. When  
you feel confident, slowly practice mowing  
around obstacles such as trees.  
Low-lift- These blades require less horsepower than  
hi-lift and medium-lift blades, and they generally work  
best with wide leaf grasses, sparse grass growth,  
and sandy soil conditions. They generally produce  
the lowest noise levels. Bahia blades are configured  
without offset, and with a maximum amount of sharp-  
ened cutting edge.  
Mulch- These blades are generally designed for use  
in cutting decks equipped with mulch baffles. The  
shape of the blade generally produces higher turbu-  
lence in order that the grass can be repeatedly cut  
and re-cut into smaller pieces. These blades gener-  
ally require more horsepower than other blades.  
Mulch blades work best when the grasses are cut at  
the highest levels, minimal lengths of grasses are  
removed, and grass conditions are generally dry.  
5. Parking the Mower:  
a. Push off the electric blade clutch switch.  
b. Use the Deck Lift Handle to raise the mow-  
ing deck to the transport position.  
c. Drive the mower to the cleanup or storage  
area.  
d. Move the throttle to slow.

7. Safety Switches: There are five safety  
switches in the electrical circuit which control  
the engine. They are (1) the blade clutch  
switch, (2) the parking brake switch, (3) the  
left and (4) the right steering lever switches  
and (5) the seat switch.They operate so that  
in order to start the engine, the blade clutch  
switch must be off, the parking brake must be  
engaged, and both steering levers must be  
opened-out to the side in the neutral position.  
Once the engine is started, the seat must be  
occupied and the parking brake must be  
released before either of the steering levers is  
folded up to the operating position or the  
engine’s electronic ignition will be grounded  
out and the engine will stop. Also, the seat  
must be occupied before the blade clutch  
switch can cause the blades to rotate.  
8. Safety Switch Operation Checks: The fol-  
lowing operational checks should be made  
daily.

tory fully charged and filled with electrolyte.  
switch “on” and try to start the engine. The  
engine should not start. If it does, the blade  
clutch switch must be replaced. If the  
engine does not start, turn the blade clutch  
switch “off” and start the engine. Now turn  
the blade clutch switch “on” and the blades  
should rotate. If the blades do not turn, the  
blade clutch switch must be replaced, the  
seat switch must be replaced or the elec-  
tric PTO clutch must be repaired. The air-  
gap should be checked every 100 hrs. (or  
less, if severe operating conditions exist  
such as when there are many on/off  
cycles, mulching operations, material col-  
lection systems used, and dusty/dirty con-  
ditions), and the air-gap adjusted if more  
than 0.025". To inspect, remove the “nega-  
tive” cable from the battery and all spark-  
plug wires. The air-gap should be checked  
with feeler gages in the three slots of the  
BBC (PTO Clutch). See page 24 for air gap  
adjustment specs. There are three inspec-  
tion slots in the brake cover. To adjust, suc-  
cessively tighten each of the three gap  
adjustment nuts an equal amount. Insert a  
feeler gage (see page 24 for specs) into  
a. Attach the Positive (red) cable.  
b. Attach the Negative (black) cable.  
c. Attach the rubber battery strap.  
5. Jump Starting  
Warning:  
Failure to use this starting procedure can  
cause sparking, and the gases in the battery  
to explode.  
a. Attach the end of the red jumper cable to  
the Positive terminal (+) of the charged  
battery.  
b. Attach the other end of the red jumper  
cable to the Positive terminal (+) of the low  
charge battery.  
c. Attach the end of the black jumper cable to  
the Negative terminal of the charged bat-  
tery.  
d. Attach the other end of the black jumper  
cable to the frame of the unit with the low  
charge battery.

each slot as the air gap adjustment nut are  
tightened. The correct adjustment occurs  
when slight contact with the feeler gage  
occurs. Engage the BBC (PTO Clutch) a  
couple of times, and re-check the air-gap.  
If it is not between the specs listed on page  
24, repeat the adjustment procedure.  
b. Parking Brake Switch: Sit in the opera-  
tor’s seat. With both steering levers  
one of the steering levers up to the operat-  
ing position. Release the operator’s seat  
and the engine should stop. If the engine  
does not stop, the seat switch must be  
replaced. With both steering levers folded  
out in the neutral position, the parking  
brake engaged and the blade clutch switch  
in the “off” position, sit in the operator’s  
seat and start the engine. Turn the blade  
clutch switch to the “on” position and the  
blades should start to rotate. Raise up  
slightly off the operator’s seat and the  
blades should stop. If the blades do not  
stop when you dismount from the opera-  
tor’s seat, the seat switch must be  
opened-out in the neutral position and the  
blade clutch switch “off”, release the park-  
ing brake and try to start the engine. The  
engine should not start. If it does, the park-  
ing brake switch must be repositioned or  
perhaps replaced. If the engine does not  
start, engage the parking brake and start  
the engine. Swing one steering lever up to  
the operating position and the engine  
should stop. If the engine does not stop,  
the parking brake switch must be reposi-  
tioned or replaced.  
replaced.  
e. Electric PTO Clutch: This clutch operates  
when the engine is running, the operator is  
in the operator’s seat and the blade clutch  
switch is turned on.This electric clutch is a  
fairly trouble free device. If a problem  
develops and the blades do not turn, first  
check the 20 amp fuse and then investi-  
gate the wiring harness and the connec-  
tions to the seat switch, the blade clutch  
switch and the electric blade clutch. Then  
check out the seat switch, the blade clutch  
switch and finally the electric blade clutch.  
c. Left and Right Steering Lever Switches:  
Sit in the operator’s seat. With both steer-  
ing levers opened-out in the neutral posi-  
tion, the parking brake engaged and the  
blade clutch switch “off”, swing the left  
steering lever up to the operating position  
and try to start the engine. The engine  
should not start. If it does, the left steering  
lever switch must be repositioned or per-  
haps replaced. Open the left steering lever  
to the neutral position and swing the right  
steering lever up to the operating position  
and try to start the engine. The engine  
should not start. If it does, the right steer-  
ing lever switch must be repositioned or  
perhaps replaced. If the engine does not  
start, Open the right steering lever to the  
neutral position and start the engine.  
Swing the left steering lever up to the oper-  
ating position and the engine should stop.  
If the engine does not stop, the left steering  
lever switch must be repositioned or  
D.Tires  
The two front wheels are caster wheels that are free  
to swivel to accommodate the direction of the Mower.  
The two rear wheels are used to propel the Mower in  
the direction of input from the drive handles. Inflation  
pressure of the rear tires is important for stability  
while the Mower is in operation. If the tire diameter is  
not equal between the two tires, the Mower will pull to  
one side.  
1. Inflation Pressure:  
a. Traction Tires—20 psi max; 10-12 psi rec-  
ommended  
b. Front Caster Wheel—28 psi max; 20-25  
psi recommended  
replaced. Open the left steering lever out  
to the neutral position and start the engine.  
Swing the right steering lever up to the  
operating position and the engine should  
stop. If the engine does not stop, the right  
steering lever switch must be repositioned  
or replaced.  
c. Cutting Deck Ball Wheels—Solid Polyure-  
thane.  
Use the Following guidelines for maintaining the tires:  
a. Balance inflation pressure between the  
rear tires to help maintain straight travel  
(see tire side wall for proper inflation pres-  
sure).  
b. Keep the valve caps tightened to prevent  
air pressure loss.  
d. Seat Switch: With both steering levers  
opened-out to the neutral position, the  
parking brake engaged and the blade  
clutch switch in the “off” position, start the  
engine. Now release the parking brake,  
hold down on the back of the operator’s  
seat against spring pressure, and swing

2. Leaking Tires: When a flat tire occurs, repair  
or replace immediately. The normal procedure  
is to remove the wheel and replace it with a  
spare. Take the leaking tire to a maintenance  
area and repair. If a tire is getting soft, park  
the mower on the nearest level, paved area. If  
the leaking tire is on a traction wheel, put  
blocks on each side of the opposite traction  
wheel and jack up the tire that leaks about an  
inch off the ground. Loosen and remove the  
lug nuts and remove the wheel. Mount a  
spare wheel and tire, replace the lug nuts, and  
using a torque wrench, tighten them to 60  
10 lb-ft.  
d. Loosen jam nuts on both ends of rod con-  
nectors. See Control Assembly in the Illus-  
trated Parts Book (ONLY if mower creeps.)  
e. Start unit and push throttle all the way on.  
f. If unit creeps forward rotate rear rod con-  
nectors counter-clockwise. And if unit  
creeps in reverse, rotate clockwise.  
Adjust the appropriate rod connector. The  
left rod for the left side of the mower and  
the right rod for the right side of mower.  
Afterward, retighten jam nuts.  
E. Brakes  
While the mower is in motion, all braking is performed  
dynamically through the hydraulic pumps and traction  
motors, controlled by the two steering levers. When the  
mower is parked with the engine shut off, the hydraulic  
system locks the traction wheels.  
If the leaking tire is on a front caster wheel,  
block both traction wheels and raise the  
caster wheel so that the tire is an inch off the  
ground. Loosen and remove the locknut from  
the axle assembly and pull the axle assembly  
from the caster yoke. The wheel and two  
spacer sleeves will drop free. Slip the axle  
assembly through one side of the caster  
yoke, through a spacer sleeve, a spare  
wheel, the other spacer sleeve and finally  
through the other side of the caster yoke.  
Then tighten the locknut on the end of the  
axle assembly.  
Note:To move the mower forward or in  
reverse by pushing, you must release the  
dynamic braking. Locate the valves on the  
pump. Turn valves counter-clockwise one  
quarter turn to push the unit. After pushing  
the mower to the desired location, return both  
valves to the operating position (See photo  
below).  
Lower the mower off the jack and continue  
mowing. The wheel with the leaking tire  
should be taken to the maintenance area, the  
tire inflated to 20 psi and the wheel placed in  
a large bucket of water. Carefully inspect the  
tire, rim and valve for escaping air bubbles  
which indicate a leak. Mark each leak with a  
yellow marking crayon and then deflate the  
tire to 8 psi and repeat the inspection. If the  
leaks you find are pin hole size to 1/16"  
diameter, the tire can be repaired using an  
aerosol can of tire inflater and latex sealer  
available from any auto supply store. Follow  
the directions on the can. If the leaks are  
larger than 1/16" diameter, the tire can be  
repaired with rubber plugs also available in a  
kit from any auto supply store. If the tire bead  
is damaged, a tube will have to be installed in  
the tire or the tire will have to be replaced.  
Hydro Release Valve  
When the mower is parked with the engine running  
and the steering levers opened out in the neutral  
position, the parking brakes should be applied. The  
parking brakes are drum-type brakes mounted on  
each traction wheel.They are both engaged by the  
same operating lever.  
3. Creeping: Creeping is the slight forward or  
backward movement of the mower when the  
throttle is on and the lapbars are in the  
opened-out position. If your mower creeps do  
the following.  
1. Adjustments: The parking brake handle is an  
overcenter lever that should engage with  
moderate force.  
a. Jack up rear of unit.  
Note:To increase parking brake capacity  
b. Place Lapbars in neutral opened-out posi-  
tion.  
c. Locate jam nuts. (Reference control  
assembly in parts list).  
tighten the brake rods going back to the brake  
arms equally. Tighten rods one full turn and  
check parking capacity. Repeat Step.  
To adjust either brake individually, tighten the hex nut  
in a clockwise direction one full turn looking down the  
21

brake rod. This will tighten the brake about .040 inch.  
Normally, both brakes should be adjusted and equal  
amount.  
Remove the fill cap and fill the tank with Shell Rimula  
15W40 oil until the oil level is a 1/4” below the oil tank  
fill neck. Leave this air space for expansion. Start the  
engine and let it run at idle for about five minutes.  
Check the filter for leaks. Idling the engine and the  
pumps in this way will purge any air from the system.  
Shut off the engine and recheck the oil level in the  
tank. Top-off if necessary until the oil level is a 1/4”  
below the oil tank fill neck.  
2. Repair: The mower is equipped with drum  
brakes and will not normally require mainte-  
nance. If they are not working properly, please  
contact your service center.  
F. Hydraulic System  
Note:After unit is up to operating tempera-  
ture, turn off engine and re-check hydraulic  
oil. If oil appears foamy or contains excessive  
air bubbles, DO NOT OPERATE UNIT. Contact  
service technician.  
WARNING:  
Never overfill the hydraulic units. Damage can  
occur if the oil level is not within the proper  
operating range.  
3. Hydrostatic Pumps and Motors: The pumps  
are the hardest-working components in the  
hydraulic system. They are in operation all the  
time the engine is running. Because of  
extremely close tolerances, wear is an impor-  
tant factor in their life. Contaminants in the  
hydraulic oil and cavitation does the greatest  
harm to the pumps. Cavitation is a blockage in  
the supply lines that produces a partial vac-  
uum causing violent bubbling in the hydraulic  
oil in the pump.  
Note: When adding hydraulic oil, do so in  
small quantities and recheck the oil level  
before adding more. It is important that you do  
not overfill the reservoir to allow for fluid  
expansion.  
1. Hoses: Check the hoses from the hydraulic  
oil tank to the oil filter to the hydraulic lines  
daily for leaks or abrasion and replace any  
damaged hoses. Make certain there are no  
kinks or twists in any hose.  
2. Hydraulic Oil Tank and Filter:  
Check the two suction hoses (the hoses con-  
nected to the filter) daily before starting the  
engine. Look for a flattened condition or any  
leaks and repair or replace as necessary. A  
flattened or leakng suction hose will permit  
cavitation to develop which can destroy the  
pumps in a short time.  
Note:Change the hydraulic oil and the oil  
filter element after the first 50 hours of opera-  
tion and every 500 hours thereafter.  
To drain the hydraulic oil tank, place a 2 gallon drain  
pan under the drain plug on the bottom of the  
hydraulic oil tank. Remove the drain plug, drain the  
tank, then replace the plug. Remove the three screws  
from the top of the oil filter and take out the oil filter  
element. You don’t have to drain the rest of the  
hydraulic system. Put the replacement filter element  
in the oil filter and lubricate the sealing surface. Install  
the three screws in the top of the oil filter to secure  
the oil filter element. (See photo below)  
Contaminants or foreign matter in the oil will  
also damage the pumps . To prevent this, use  
a filter that captures particles as small as 25  
microns or 25 millionths of a meter in diame-  
ter. You can help in the battle against dirt by  
being very careful when you remove or repair  
a component in the hydraulic system. Thor-  
oughly clean off any component before you  
work on it. Plug the ends of any hose or line  
you remove with a rubber or plastic plug. Use  
plastic caps to seal off the ends of hydraulic  
fittings. Place any component you remove in a  
clean plastic bag so it can’t pick up dust or  
dirt. Clean your hands frequently when work-  
ing on the hydraulic components.  
Screw  
Note:The pumps are not owner-repairable.  
If a pump fails, contact your Cub Cadet Com-  
mercial dealer. Do not disassemble the pump.

4. Steering Lever Adjustments: Place the  
mower on level ground with the engine run-  
ning, parking brake off and steering levers  
opened out to the neutral position. If the  
Note:Always wipe off the hydraulic tank fill  
cap and the area around it before removing  
the cap to prevent dirt from contaminating the  
oil.

Mower begins to creep, adjust the Steering  
Levers.  
b. Sharpen the blades so that the mower will  
be ready to use when needed.  
c. Protect the metal surfaces. Repair  
scratches with the appropriate touch-up  
spray paint. Brush a rust preventive oil on  
any unpainted surfaces including the pul-  
leys and blades. (Be careful not to get any  
oil on the drive belts.)  
If the mower creeps, first determine whether it  
creeps to the right or left side and which direc-  
tion the mower moves — to the front or the  
rear. To make the adjustment, place the steer-  
ing levers in the opened-out neutral position  
and set the parking brake, shutoff the engine,  
take the key from the ignition switch and pivot  
the seat forward. If the mower creeps to the  
right, you will adjust the linkage on the left  
side of the mower and vice-versa. Remove  
the cap screw and lock washer that secure  
the linkage control arm rod end bearing to the  
control lever pivot. Loosen the jam nut which  
prevents the rod end bearing from turning. If  
the mower creeps forward, thread the rod end  
bearing one-half turn clockwise into the link-  
age control arm. If the mower creeps back-  
ward, thread the rod end bearing one half turn  
counterclockwise out of the linkage control  
arm. Then tighten the jam nut and reconnect  
the rod end bearing to the control lever pivot  
by replacing the cap screw and lock washer.  
d. Lubricate the mower.  
e. Drain the engine oil. The engine should be  
warm so that all the oil drains. Replace the  
engine oil filter and refill the crankcase with  
fresh oil.  
f. Clean the battery and make sure it is fully  
charged.  
g. Inspect the hydraulic hoses, lines and fit-  
tings. Replace as necessary.  
h. Jack the mower up and store it on blocks to  
take the weight off of the tires.  
2. To Put the Mower Back in Service:  
a. Check the battery. Charge if necessary.  
b. Check the level of the oil in the crankcase  
and the hydraulic tank.  
c. Lower the mower off the block and check  
the tire pressure.  
After adjusting the steering linkage, swing the  
seat back to its normal position and place the  
steering lever on the side you adjusted up to  
the operating position. If you feel a slight push  
forward or a slight pull backward from the  
neutral position you must adjust the lever  
return assembly. To do this, swing the steering  
lever back out to the neutral position, pivot the  
seat forward and loosen the jam nut on the  
lever return rod where it is threaded into the  
hex-shaped end of the lever return bolt. If the  
steering lever was pushed forward, turn the  
hex-shaped lever return bolt clockwise one-  
half turn off of the lever return rod. If the steer-  
ing lever was pulled back, turn the hex shaped  
lever return bolt counterclockwise one-half  
turn onto the lever return rod. Then tighten the  
jam nut, pivot the seat back into the operating  
position and start the mower to check that  
your adjustments were made correctly.  
d. Push the mower outdoors and start the  
engine. Let the engine idle until it has  
warmed up completely (4 to 5 minutes).  
G. Storage  
1. General: If your mower will not be in service  
for a few months, it should be stored in a dry  
location that is not subject to drastic changes  
in temperature. Before storing, the following  
maintenance procedures should be per-  
formed.  
a. Clean the mower. The entire tractor and  
cutting deck should be washed and  
cleaned.

If mower tracks to one side with both lap bars in fully  
forward position:  
NOTE: RPM Specs. are for free running engines under no load.  
1. Verify that the lap bars are in the neutral posi-  
tion, the parking brake is on, and the PTO  
drive is disengaged.  
2. Start the mower and let it run at approximately  
half throttle for 3-5 minutes to bring the engine  
up to operating temperature.  
3. Locate the Hour Meter/Tachometer/ Service  
Minder display on the right hand operator con-  
trol panel. (see Fig.1 on page 9 of the manual)  
This display defaults to Tachometer mode  
when engine is running.  
4. Move the throttle lever to the high speed posi-  
tion and note the RPM reading on the display.  
5. Move the throttle lever back to the low speed  
position and again note the displayed RPM’s.  
6. Compare these noted RPM readings to the  
specifications in Table 1, for the engine that is  
on your mower.  
7. If the readings do not correspond to the  
ranges in the table, refer to the engine  
owner’s manual for the proper adjustment pro-  
cedures.  
8. If adjustments per the engine operator’s man-  
ual do not result in proper RPM readings, con-  
tact your service technician.  
9. Note: The throttle cable sheath may shrink or  
slip over time, changing the relationship  
between the throttle lever on the left hand  
operator control panel and the throttle arm on  
the engine. To readjust the throttle cable:  
a. Make sure the engine is off, place lap bars  
in the neutral position, set the parking  
brake, and disconnect and ground both of  
the spark plug wires.  
1. Check air pressure in all four tires:  
a. Pressure should be within specified ranges  
and balanced side-to-side.  
b. Rear tires 10-12 psi. recommended (20 psi  
MAX.)  
c. Front tires 20-25 psi. recommended (28 psi  
MAX.  
2. Check hydraulic fluid level (Ref. Engine  
owner’s manual)  
3. Verify that the mower does not creep when  
the engine is running, the lap bars are in the  
neutral position and the parking brake is  
released. (Refer to section D-3 on page 21 of  
this manual if this condition exists).  
4. Recheck the tracking after any adjustments  
based on the above.  
5. If uneven tracking persists, adjust as follows.  
(see Fig. 10)  
a. Unit tracks to the RIGHT, adjust Left lap  
bar stop bolt to make it longer.  
b. Unit tracks to the LEFT, adjust Right lap  
bar stop bolt to make it longer.  
6. Re-check the tracking and make any fine tun-  
ing adjustments to the lap bar stop bolts as  
required.  
Note:If stop bolt is adjusted too far, track-  
ing problem will change sides. Make the fine  
tuning adjustments by shortening the same  
bolt.  
b. Locate and loosen the cable clamp on the  
engine throttle plate.  
c. Place the operator’s throttle lever to the  
high speed position and then slide the  
cable through the clamp until the throttle  
arm is in the full throttle position. (Ref.  
Engine owner’s manual)  
d. Tighten the cable clamp.  
e. Move the operator’s throttle lever between  
high and low speed and verify that the  
engine throttle arm also moves through it’s  
full range of motion.  
f. Repeat as required to obtain proper throt-  
tle adjustment.  
g. Verify proper throttle adjustment by check-  
ing RPM readings as outlined above.

3. Check factory settings of lap bars for the con-  
ditions listed above.  
C. Deck Corner Ball Wheel Roller Settings  
1. Matching the set heights of the ball rollers on  
the four corners of the mower deck to the  
desired cut height will prevent edge scalping  
and minimize any side-to-side variance in cut  
height.  
2. There are three height adjustment holes in  
the bracket that mount the ball rollers to the  
deck.  
Note:If lap bar adjustments are required,  
height adjustments should be made prior to  
angular adjustments.  
4. To adjust the height of the lap bars,  
a. Remove the nuts from the lap bar mounting  
bolts (see Fig. 11).  
b. Remove the bolts and lap bar and repostion  
to the seconc set of holes in the mounting  
block.  
a. Use the top set of holes for cut heights of 2  
inches or lower.  
c. Replace the bolts and nuts and tighten to  
28-34 lb-ft.  
b. Use the middle set of holes for a 2-1/2 - 3-1/2  
inch cut height.  
c. Use the bottom set of holes for cut heights of  
4 inches or higher.  
1. If angular adjustments are also required,  
nuts can be tightened until snug at this  
point.  
d. The same adjustments should be made to  
both sides of the mower.  
D. Deck Center Anti-Scalp Roller Settings  
1. The front and rear rollers help prevent the  
scalping of high spots and uneven terrain  
across the center section of the deck.  
2. The rollers on the front of the deck are fixed at  
the factory and can not be adjusted.  
3. The rollers on the rear of the deck can be  
adjusted downward one inch.  
5. To adjust the front-to-rear angle of the lap bars,  
a. Loosen the nuts on the lap bar mounting  
bolts, leaving the bottom one fairly snug.  
b. The top hole is slotted, allowing the lap bar  
to pivot on the bottom bolt.  
c. Move lap bar to the desired angle and  
tighten the nuts to 28-34 lb-ft.  
a. Lowering the roller will increase the strip-  
ing effect left behind the mower.  
b. This positioning of the rear roller will also  
help to filter the mulched grass clippings  
into the turf.  
Note:In the neutral position, the handles of  
the lap bars should be aligned with approxi-  
mately a one inch gap between the tips. Adjus-  
the gap by adding shim washers to the top  
mounting bolt between the lap bar and the  
mounting block.  
c. Roller should not be lowered if the cut  
height is set at 2-1/2 inches or lower.  
d. Check the results of any adjustments to  
the conditions described in section a,  
above. Repeat any adjustment procedures  
as required until all conditions are met.  
E. Lap Bar Adjustment  
1. Proper lap bar and seat adjustment will result  
in the following:  
a. In the neutral position with hands on the  
lap bars,  
1. Operator’s upper arms should be relaxed  
and approximately vertical.  
2. Operator’s forearms should be approxi-  
mately vertical.  
b. In the full forward position,  
1. Operator’s back should stay in contact  
with the seat back.  
2. Lap bars should not contact operator’s  
legs.  
Lap Bar Mounting Bolt and Nuts  
c. In the full reverse position,  
1. Lap bars should not contact the opera-  
tor’s legs or torso.  
Figure. 11  
2. Set the seat to the preferred operating position.  
a. Adjustment lever is located under the front  
edge of the seat.  
b. The seat has five inches of front-to-rear  
adjustment available.

aligned along the mower centerline. The blade-  
to-ground height at the rear of the blade tip  
should be 1/8" to 1/4” higher than the front tip.  
This is referred to as blade pitch. The sam  
height difference should be true for the left  
blade, measured front and back.  
F. Deck leveling Procedure  
1. Park the mower on a flat paved surface, engage  
the parking brake, shut off the engine, remove  
the key from the ignition switch, disconnect the  
spark plug wires and using the transport lever,  
lower the mowing deck into the 4" height of cut  
position. (The 4" height of cut position is recom-  
mended in order for one to see and obtain a  
measurement. Any height of cut position is  
acceptable as long as a proper measurement  
can be taken.)  
2. Check the right and left front tire pressure.  
Adjust as necessary to 20-25 psi. Tire pressure  
can affect blade height by as much as a 1/4”.  
3. Check the right and left rear Drive tire pressure.  
Adjust as necessary to 10-12 psi.  
4. Measure blade-to-ground height at the front tip  
of the right blade. To obtain an accurate mea-  
sure, align blades in parallel with mower center-  
line, (i.e. front to back).  
5. Measure blade-to-ground height at the front tip  
of the left blade. Be sure to measure at the  
blade tip with the blades arranged in proper  
position.  
8. To adjust the blade pitch the deck pitch must be  
adjusted. Loosen the inner jam nuts at the rear  
of the horizontal threaded rods. Start at Point C  
to raise the rear of the deck, tighten the rear  
outer jam nut to raise the deck pitch. Adjust the  
rear jam nut at Point D to take the “slack out of  
the threaded rod.  
9. The final adjustment would be to take the “slack”  
out of the left rear linkage (Point D) by adjusting  
the jam nuts on the eyebolt. Loosen the jam  
nuts and tighten the upper nut to remove “slack”.  
10. In many cases it will be necessary to adjust  
deck height using both eyebolt adjustments and  
pitch adjustment to achieve the correct blade-to-  
ground heights. If you remember that the front  
right blade tip adjustment is fixed and you level  
to that height, adjusting the decks will be simpli-  
fied.  
11. Once the deck is level one may find that the  
height of cut does not match the height of cut  
indicator. A final adjustment may be made by  
lowering or raising the height of cut link accord-  
ingly. To raise the deck: remove the shoulder  
bolt mounting the height of cut link to the lift han-  
dle and reassemble the shoulder bolt in the low-  
est of the three holes. To lower the deck: remove  
the shoulder bolts mounting the height of cut  
link, flip the height of cut link around and reas-  
semble the shoulder bolts in the top of the set of  
three holes and the bottom hole. (see Fig. 12)  
6. To level the deck, adjust the eyebolt at the left  
front of the deck (Point B) so that the blade-to-  
ground height at the right front blade tip  
matches that of the left front blade tip. This is  
done by loosening the jam nuts on the eyebolt  
and tightening the upper nut to raise the deck  
and loosening the nut to lower the deck. The  
right front blade tip height is fixed so you must  
adjust the left front tip to match it.  
7. Measure the blade-to-ground height at the right  
rear blade tip. Again be sure to measure at the  
blade tip at the rear of the right blade when

Use only good quality lubricating oil, such as shell Rim-  
ula 15W40 which meets Caterpillar ECF-I and either of  
the following:  
Fuel & Lube Specifications  
A.Fuel Specifications  
Use good quality fuel to get the correct power and per-  
formance from the engine. The recommended fuel spec-  
ification for Caterpillar engines is shown below.  
• API-CH-4 plus  
• ACEA E5  
Note: API CI-4 plus and ACEA ES oils that have not  
met the requirements of Caterpillar’s ECF-I specification  
may cause reduced engine life.

85% at 350 C (662 F)  
Caution: Always ensure that the correct viscosity grade  
of lubricating oil is used for the ambient temperature  
range in which the engine will run as shown in the chart  
below.  
Cetane number: Cetane number indicates ignition per-  
formance. Fuel with a low cetane number can cause  
cold start problems and affect combustion.  
Recommended SAE viscosity grades  
Viscosity: Viscosity is the resistance to flow and if this  
A
is outside limits, engine performance can be affected.

5W20  
10W30  
15W40  
20W50  
Density: Low density will reduce engine power, higher  
density will increase engine power and exhaust smoke.  
Sulphur: High sulphur content (not normally found in  
Europe, North America or Australasia) can cause engine  
wear. if only high sulphur fuels are available, it will be  
necessary to use a highly alkaline lubricating oil in the  
engine or reduce the lubricating oil change interval.

Distillation: This is an indication of the mixture of differ-  
ent hydrocarbons in the fuel. A high ratio of light weight  
hydrocarbons can affect the combustion characteristics.  
Viscosity chart  
A = Recommended viscosity  
B = Ambient temperature  
Low temperature fuels: Special winter fuels may be  
available for engine operation at temperatures below  
0 C (32 F). These fuels limit the formation of wax in the  
fuel oil at low temperatures. If wax forms in the fuel oil,  
this could stop the flow of fuel oil through the filter.  
Ensure the lubricating oil sump is filled slowly after warm  
up, check with the dipstick that the oil level is correct.  
Change the oil and filter in accordance with the service  
instruction.  
Aviation kerosene and R.M.E. type fuels: These fuels  
may be used, but can effect the engine performance and  
starting ability. The only aviation fuels that are permitted  
for use with these engines are: JP5, Jet A and JP8 pro-  
viding that 5% spindle oil is added, Aviation fuel JP4 is  
not recommended. For more information on aviation  
fuels refer to the Caterpillar application department.  
Only up to 5% R.M.E. in mineral oil diesel fuel is permit-  
ted. Biodiesel blends of up to 5% B100 and #2 diesel  
fuel (B5) are allowed.  
Electrical shut-off solenoid (ESOS): The ESOS is fit-  
ted to the right hand side of the cylinder block, at the  
rear of the fuel injection pump. When the solenoid is de-  
energised, a control rod pushes the fuel control rack to  
the ‘no fuel position’ in the injection pump. The unit oper-  
ates from a 12V supply in an ‘energise to run’ condition,  
an electrical failure will give automatic fuel shut-off.
