FORWARD  
The MMZ Gasoline Powered Hydraulic Driven Rotary Mowers were developed to  
provide superb maneuverability, mid-mount cutting capability for professional land-  
scapers, commercial lawn service companies, 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 properly operated and maintained, 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 misuses 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. Notwithstanding, these factors are  
also dependent upon the awareness, concern, pru-  
dence and proper training of the personnel involved  
in the operation, transport, maintenance and stor-  
age of the equipment.

SAFETY PRECAUTIONS  
A. General  
1. Read this Operator’s Manual before starting the mower. Study the  
controls and learn the proper sequence of operation.  
2. Do not allow anyone to operate or maintain this machine who has  
not read this manual. Never permit children to operate this  
machine.  
3. Never carry passengers.  
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.  
6. Disconnect the spark plug wires or 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 adequate 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.  
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.  
10. Lead-acid batteries generate hydrogen and oxygen gases which  
form an explosive mixture. Keep sparks and flames away at all  
times.  
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 doctor familiar with this form of injury or serious complications  
may result.  
B. Related to Fuel  
1. Fuel is highly flammable. Please respect it.  
2. Do not smoke or permit others to smoke while handling fuel.  
3. Always use approved containers for fuel.  
4. Always shut off the engine and permit it to cool before removing  
the fuel tank cap.  
5. Always fill the fuel tank outdoors.  
6. If the fuel container spout will not fit inside the fuel tank opening,  
use a funnel.  
4

7. When filling the fuel tank, stop when the fuel reaches one inch from the  
top. This space is necessary for tank expansion. Do not overfill  
.
8. Wipe up any spilled fuel.  
C. 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 posi-  
tion.  
4. Always remove debris and other objects from the area to be  
mowed.(Note: debris and loose grass will reduce traction.)  
5. Mow only in daylight.  
6. Watch for holes, sprinkler heads and other hidden hazards.  
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.  
10. Always mow up and down slopes, never across 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 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 compo-  
nents clean and free of grease, grass and leaves to reduce the  
chance of fire and to permit proper cooling.

Ignition Switch  
A. Controls  
1. Engine Ignition and Start Switch: (See Figure 1.) Located on the  
instrument housing below the right side of the operator’s seat.  
When the key is inserted and turned clockwise, 45 degrees, the  
ignition circuit is closed. 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 steering 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.  
2. 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.  
3. 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 forearm’s length away. These levers control all of the  
movements of the mower. Pushing both levers forward causes the  
mower to move forward. 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.  
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.  
Note:  
The Steering Lever will return toward neutral when released, but they  
should be placed in neutral by the driver. If the Drive Handles are not placed in neutral,  
the tractor may creep.  
4. Electric Blade Clutch Switch: (See Figure 1.) Located on the  
right side of the mower beside the ignition switch. This is an “on/off”  
toggle switch that controls the electric blade clutch which supplies  
power to the cutting blades through the PTO. The switch must be  
turned off to start the engine and should be turned off for safety  
any time another person 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.  
5. Parking Brake: (See Figure 3.) Located on the left side of the trac-  
tion unit. The handle is an overcenter lever which applies the inter-  
nal drum-type brake on each drive wheel when the handle is pulled  
to the rear. The brake must be engaged in order to start the engine.  
6. Deck Lift Handle: (See Figure 3.)

the deck lift handle and move it outward. This allows the handle to  
move forward, lowering the deck to the cutting position.  
7. Fuel Shutoff Valve: (See Figure 4.)  
Located on top of the fuel tank. When  
turned in a clockwise direction until it  
stops, it will shut off the flow of fuel to  
the engine. When turned in a coun-  
terclockwise direction it will open and  
allow fuel to flow to the engine. 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.  
Fuel Shutoff Valve  
Figure. 4  
8. Seat Adjustment Lever: The Seat  
Adjustment Lever is located beneath the seat. The Seat Adjust-  
ment Lever is used to move the seat forward and backward. To  
place the seat in the desired position pull the seat adjustment lever  
to the left then push the seat forward or back to the desired posi-  
tion. Release the lever so the seat will lock in place.  
9. Digital Tachometer and Hour Meter: (See Figure 1) 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 running time.  
10. Choke Lever: (See Figure 2) The Choke Lever is located on the  
left instrument panel next to the seat. The Choke Lever is operated  
manually. Having the Choke Lever in the ON position helps the  
engine to start during initial start-up. During normal operation the  
Choke Lever should be in the OFF position.  
Note:  
There will be a flashing “LUBE” for each recommended lubrication interval.  
There is a flashing “OIL” at each recommended engine oil and filter change.  
B. Initial Adjustments  
1. Check the fluid levels and tires:  
Note:  
These checks should be made daily, before starting the engine.  
a.  
Fuel: Using a good grade of unleaded, regular gasoline (for  
a gasoline engine), 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 OVER-  
FILL. Space must be left for expansion.  
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  
9

oil through the fill tube using a funnel to bring it up to the  
top of the operating range.  
Note:  
Gasoline Engine: Use SAE 10W30 or SAE 10W40 engine oil, rated for ser-  
vice SJ.  
c.  
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 up to the  
lowest hole on the oil tank fill neck. The top hole is for vent-  
ing. If the oil level is low, fill with a good grade of SAE20W-  
50 oil.  
d.  
Tires: 10 psi Rear, 30 psi Front Caster Tires  
Note:  
New tires are overinflated in order to properly seat the bead to the rim. The  
normal working pressure for the traction tires is 8-10 psi. The front caster wheels  
should be inflated to 30 psi.  
2. Check that all Nuts, Bolts and Screws are Tight.  
3. Check the tension of the deck drive belts.  
a.  
b.  
Remove the deck cover  
The tension of the deck drive belts are maintained by a  
spring mechanism that adjusts for wear and stretch.  
Examine the belts for cuts, fraying, and excessive wear.  
Replace if any of these are detected.  
c.  
d.  
Replace the deck cover.  
4. Adjust the Mowing Deck: The cutting height is set anywhere in  
the range of 1-1/2" to 5-1/2". You may need to adjust the mowing  
deck to achieve the proper angle for mowing. Follow the proce-  
dures below to set the appropriate angle to the mowing deck.  
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 posi-  
tion.  
b.  
Using a ruler, pencil and paper, measure and note the dis-  
tance from the paved surface to the bottom edge of the  
mowing blade at the front and the back of the deck on each  
side of the mower. (Four dimensions.)  
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.

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).  
Deck Lift Spring inner bolt  
Deck Links  
Figure. 5  
d.  
e.  
Lower the mower deck to the  
cutting position. With a  
wrench loosen the inner rear bolt 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 bolt of the Deck Lift Spring Assist. Repeat this  
procedure on the opposite side of the MMZ. Once the deck  
is adjusted, retighten bolts.  
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. Retighten bolts.  
Raise the mowing deck to the transport position using the  
transport lever.  
f.  
g.  
Use the transport lever to lower the mowing deck to the cut-  
ting position and repeat step “b.” above to make sure that  
the desired cutting height has been attained. If the dimen-  
sions are not correct, repeat steps “c.” through “f.” above.  
5. Lubricate all fittings listed in the maintenance section.  
C. Break-In And Operation  
DANGER:  
Reread the “When Mowing” Safety Precautions.  
1. Start the Engine:  
a.  
b.  
c.  
Open the fuel shutoff valve.

e.  
f.  
Push the throttle control to a position a third of the way  
between slow and fast.  
Insert the key in the ignition and start switch and turn the  
switch to “On”.  
g.  
h.  
Gasoline Engine: If the engine is cold, push the choke to  
the on position.  
Turn the ignition key in a clockwise direction 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.  
i.  
Gasoline Engine: Once the engine starts, push the choke  
on halfway and as the engine warms, push the choke off all  
the way.  
2. Operating the Mower: Operating a zero-turning-radius mower is  
not like operating a tractor-type riding mower. The zero-turning-  
radius mower is much more maneuverable and much less fatiguing  
to operate. However, getting used to the fingertip control of the  
zero-turning-radius mower takes some practice. We strongly rec-  
ommend that you locate a “test area” where you can operate the  
mower for about 30 minutes without being disturbed.  
a.  
b.  
c.  
Get into the operator’s seat.  
Start the engine.  
Use the transport lever to raise the mowing deck to the  
transport position. Make sure the blade clutch switch is off.  
After the engine has warmed, adjust the throttle to the fast  
position.  
d.  
e.  
f.  
Release the parking brake.  
Fold in the steering levers to the operating position.  
WARNING:  
When operating this mower forward, do not allow the steering levers  
to return to the neutral 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.  
h.  
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 for-  
ward.  
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.  
12

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 care-  
ful 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 posi-  
tion and pull on the electric blade clutch switch to start the  
blades rotating.  
k.  
Practice mowing in straight passes. When you feel confi-  
dent, slowly practice mowing around obstacles such as  
trees.  
3. Parking the Mower:  
a.  
b.  
Push off the electric blade clutch switch.  
Use the Deck Lift Handle to raise the mowing deck to the  
transport position.  
c.  
d.

6. Fuses: There is one fuse located in the wiring between the ignition  
and start switch and other electrical components. This is a stan-  
dard plug-in type automotive fuse rated at 7.5 amp.  
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 shorted  
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 following operational  
checks should be made daily.  
a.  
Blade Clutch Switch: Sit in the operator’s seat. With both  
steering levers opened-out in the neutral position and the  
parking brake engaged, turn the blade clutch 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 electric PTO clutch must be repaired.  
Parking Brake Switch: Sit in the operator’s seat. With both  
steering levers opened-out in the neutral position and the  
blade clutch switch “off”, release the parking brake and try  
to start the engine. The engine should not start. If it does,  
b.  
19  
Download from Www.Somanuals.com. All Manuals Search And Download.  
the parking 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  
repositioned or replaced.  
c.  
Left and Right Steering Lever Switches: Sit in the opera-  
tor’s seat. With both steering levers opened-out in the neu-  
tral position, 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 perhaps 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  
steering lever switch must be repositioned or perhaps  
replaced. If the engine does not start, Open the right steer-  
ing lever to the neutral position and start the engine. Swing  
the left steering lever up to the operating position and the  
engine should stop. If the engine does not stop, the left  
steering lever switch must be repositioned or 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 repo-  
sitioned or replaced.  
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 one of  
the steering levers up to the operating 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 park-  
ing 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 operator’s seat, the seat  
switch must be replaced.  
e.  
Electric PTO Clutch: This clutch operates when the  
engine is running, the operator is in the operator’s seat and  
20

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 7.5 amp fuse in the yel-  
low, 16-gauge wire between terminal “L” (for the Gasoline  
Engine) on the ignition switch and the hour meter and then  
investigate the wiring harness and the connections 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.  
D.Tires  
The two front wheels are caster wheels that are free to swivel to  
accommodate the direction of the MMZ.  
The two rear wheels are used to propel the MMZ in the direction of input  
from the drive handles. Inflation pressure of the rear tires is important for  
stability while the MMZ is in operation. If the tire diameter is not equal  
between the two tires, the MMZ will pull to one side.  
1. Inflation Pressure:  
a.  
b.  
c.  
Traction Tires—20 psi max; 8-10 psi recommended  
Front Caster Wheel—40 psi max; 25-30 psi recommended  
Cutting Deck Ball Wheels—Solid Polyurethane.  
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  
pressure).  
b.  
Keep the valve caps tightened to prevent air pressure loss.  
2. Leaking Tires: When a flat tire occurs, repair or replace immedi-  
ately. 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  
lbs.  
±
10 ft-  
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  
21

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.  
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.  
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.  
a.  
b.  
c.  
Jack up rear of unit.  
Place Lapbars in neutral opened-out position.  
Locate jam nuts (ref no. 23 in the control assembly parts  
list). See Illustrated Parts Book.  
d.  
Loosen jam nuts on both ends of rod connectors. (ONLY if  
mower creeps.)  
e.  
f.  
Start unit and push throttle all the way on.  
Locate the left and right rod connectors between each jam  
nut. See Control assembly in the Illustrated Parts Book.  
If unit creeps forward rotate counter-clockwise. And if unit  
creeps in reverse, rotate clockwise.  
g.  
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.  
22  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Note:  
If you wish to move the mower by  
pushing, you must release the dynamic brak-  
ing. Locate the levers at the rear of the mower.  
Pull both levers out and lock in position. After  
pushing the mower to the desired location,  
return both levers to the operating position  
(See photo at right).  
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.  
Hydro Release Levers  
1. Adjustments: The parking brake handle is an overcenter lever that  
should engage with moderate force.  
Note:  
To increase parking brake capacity 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, disconnect the brake rod from the brake  
arm by removing the cotter pin from the clevis pin and pulling the clevis pin  
from the brake clevis. Loosen the hex nut and turn the brake clevis in a  
clockwise direction one full turn looking down the brake rod. This will  
tighten the brake about .040 inch. Tighten the hex nut and reassemble the  
brake clevis to the brake shaft assembly. Normally, both brakes should be  
adjusted and equal amount.  
2. Repair: The mower is equipped with internal wet drum brakes and  
will not normally require maintenance. If they are not working prop-  
erly, please contact your service center.  
F. Hydraulic System  
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:  
Note:  
Change the hydraulic oil and the oil filter after the first 50 hours of operation  
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. Place the drain pan under the filter and  
remove the filter by unscrewing in a counterclockwise direction. The filter  
will be full of oil, so empty it into the drain pan. You don’t have to drain the  
23

rest of the hydraulic system. Fill the replacement filter with a good grade of  
20W-50 oil and lubricate the sealing surface. Screw the filter onto the filter  
base until it seats and then another one-half turn to seal.  
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.  
Remove the fill cap and fill the tank with the same 20W-50 oil selected for  
the filter until the oil level is up to the level of the second hole in the fill  
tube. 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 up to the second hole n the fill tube.  
3. Hydrostatic Transmissions 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 important factor in their life. Contami-  
nants in the hydraulic oil and cavitation does the greatest harm to  
the pumps. Cavitation is a blockage in the supply lines that pro-  
duces a partial vacuum causing violent bubbling in the hydraulic oil  
in the pump.  
Check the two suction hoses (the hoses connected 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.  
Contaminants or foreign matter in the oil will also damage the  
pumps . To prevent this, use a filter that captures particles as small  
as 30 microns or 30 millionths of a meter in diameter. You can help  
in the battle against dirt by being very careful when you remove or  
repair a component in the hydraulic system. Thoroughly 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 working on the hydraulic components.  
Note:  
The pumps are not owner-repairable. If a pump fails, call our Service  
Department for a replacement. Do not disassemble the pump.  
4. Steering Lever Adjustments: Place the mower on level ground  
with the engine running, parking brake off and steering levers  
24

opened out to the neutral position. If the MMZ begins to creep,  
adjust the Steering Levers.  
If the mower creeps, first determine whether it creeps to the right or  
left side and which direction the mower moves — to the front or the  
rear. To make the adjustment, place the steering 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 for-  
ward. 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 bear-  
ing 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 linkage control  
arm. If the mower creeps backward, 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 con-  
trol lever pivot by replacing the cap screw and lock washer.  
After adjusting the steering linkage, swing the seat back to its nor-  
mal 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 for-  
ward, turn the hex-shaped lever return bolt clockwise one-half turn  
off of the lever return rod. If the steering 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.

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 performed.  
a.  
b.  
c.  
Clean the mower. The entire tractor and cutting deck  
should be washed and cleaned.  
Sharpen the blades so that the mower will be ready to use  
when needed.  
Protect the metal surfaces. Repair scratches with the  
appropriate touch-up paint spray. Brush a rust preventive  
oil on any unpainted surfaces including the pulleys and  
blades. (Be careful not to get any oil on the drive belts.)  
Lubricate the mower.  
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.  
d.  
e.  
f.  
Gasoline Engine: Drain all the fuel. Close the fuel tank  
shutoff valve. Disconnect the fuel line from the carbuetor  
and put the end into an approved fuel container. Open the  
fuel tank shutoff valve and drain the fuel tank and  
line into the approved container. Replace the fuel line on  
the carburetor. Start the engine and allow it to run out of  
fuel. This will prevent gum and varnish deposits from form-  
ing. Replace the fuel filter.  
g.  
Gasoline Engine Only: Remove the spark plugs and pour  
approximately one ounce of oil into each cylinder. Crank  
the engine one or two turns to spread the oil evenly on the  
cylinder walls. Replace the spark plugs.  
h.  
i.  
Clean the battery and make sure it is fully charged.  
Inspect the hydraulic hoses, lines and fittings. Replace as  
necessary.  
j.  
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.  
b.  
Check the battery. Charge if necessary.  
Gasoline Engine Only: Remove the spark plugs and wipe  
them off. Using the starter, crank the engine to pump the  
excess oil out of the spark plug holes. Replace the spark  
plugs and the ignition leads. Refill the fuel tank with fresh  
gasoline.  
c.  
d.  
Check the level of the oil in the crankcase and the hydraulic  
tank.  
Lower the mower off the block and check the tire pressure.
