Exmark will get the parts to the dealer the next business day or  
the part will be FREE* Guaranteed!!  
How the Program Works  
1.  
If dealer does not have part in stock for a "down" unit at  
the time of request by customer, the dealer contacts his  
distributor by 1:00 p.m., local time, and requests Exmark  
Parts Plus shipment of six (6) line items or less.  
2.  
Distributor ships part(s) to dealer or customer, as  
requested by dealer, same day, overnight UPS  
Distributor bills dealer for part and freight charges where  
applicable.  
3.  
4.  
5.  
6.  
If distributor does not have the part(s) in stock to satisfy Exmark Parts Plus order, he contacts Exmark by 3:00 p.m.,  
central time, with an Exmark Parts Plus order of six (6) line items or less.  
If order is received by 3:00 p.m. central time, Exmark ships part(s) direct to dealer or customer, as requested by  
distributor, same day, overnight UPS, Exmark bills the distributor for parts and shipping charges, where applicable.  
The customer pays for the part and freight if it is shipped under the Exmark Parts Plus and if it arrives in  
accordance to the program.  
Who pays for the part and freight if it fails to arrive overnight in accordance to the program?  
A. Under any circumstance the customer does not pay.  
B. If the part does not arrive overnight due to:  
1. The dealer not submitting the Exmark Parts Plus order to his Exmark distributor by 1:00 p.m., the dealer  
pays for the part and freight.  
2. The Distributor being unable to ship the part the same day or not submitting the Exmark Parts Plus order  
to Exmark by 3:00 p.m., central time, the Distributor pays for the part and freight.  
3. Exmark being unable to ship the part and the Exmark parts order is received by 3:00 p.m., central time,  
Exmark pays for the part and freight.  
4. If the part does not arrive overnight due to the shipper (UPS), the shipper pays for the freight and Exmark  
pays for the part.  
The following restrictions apply -- The Exmark Parts Plus Program is available only through participating Exmark  
Dealers and applies only to orders submitted on this program Monday through Thursday. Parts Plus service is available  
only in the 48 contiguous United States. UPS has initiated a Saturday delivery program to many areas of the continental  
United States and can be requested for an overnight shipment on Friday to be delivered Saturday. The next day air  
charge, plus the Saturday delivery fee will be the responsibility of the purchaser. Exmark Mfg. will assume no  
responsibility for Saturday delivery shipments. To qualify, all Exmark Parts Plus orders must be received by Exmark by  
3:00 p.m., central time. Orders must be six (6) line items or less. Exclusions from the Exmark Parts Plus Program are:

all who operate this unit.  
1.2.2  
Read the instructions carefully. Familiarize yourself with the controls and the  
proper use of the equipment. If the operator(s) or mechanic(s) can not read  
English, it is the owner’s responsibility to explain this material to them.  
1.2.3  
1.2.4  
Do not allow operation of this machine by untrained personnel. Never allow  
children, teenagers, or people unfamiliar with these instructions to use the mower.  
Local regulations may restrict the age of the operator.

1.3.4  
Thoroughly inspect the area where the equipment is to be used and remove all  
stones, sticks, wires, bones and other foreign objects which may damage the  
equipment or cause personal injury to the operator or bystanders.  
WARNING  
POTENTIAL HAZARD  
Engine exhaust contains carbon monoxide, which is  
an odorless deadly poison.  
WHAT CAN HAPPEN  
Carbon monoxide can kill you.  
HOW TO AVOID THE HAZARD  
Do not run engine indoors or in a small confined area  
where dangerous carbon monoxide fumes can collect.  
DANGER  
POTENTIAL HAZARD  
In certain conditions gasoline is extremely flammable  
and highly explosive.  
WHAT CAN HAPPEN  
A fire or explosion from gasoline can burn you, others,  
and cause property damage.  
HOW TO AVOID THE HAZARD  
DO NOT smoke while refueling, and stay away from  
an open flame or where gasoline fumes may be ignited  
by spark.  
Refuel only in a well ventilated area, or refuel  
outdoors.  
Store gasoline in an approved container and keep it  
out of the reach of children.  
Add fuel before starting the engine. Never remove the  
cap of the fuel tank or add fuel when engine is running  
or when the engine is hot.  
Never fill the fuel tank so that the gasoline level rises  
above a level that is 1/2” below the bottom of the filler  
neck to allow for gasoline expansion and prevent fuel  
spillage.  
If fuel is spilled, DO NOT attempt to start the engine.  
Move away from the area of the spill and avoid  
creating any source of ignition until fuel vapors have  
dissipated.

DANGER  
POTENTIAL HAZARD  
In certain conditions gasoline is extremely flammable  
and highly explosive.  
WHAT CAN HAPPEN  
A static charge can ignite gasoline vapors. A fire or  
explosion from gasoline can burn you, others, and  
cause property damage.  
HOW TO AVOID THE HAZARD  
Purchase and store gasoline only in an approved  
container.  
Always place gasoline containers on the ground away  
from your vehicle before filling.  
Do not fill gasoline containers inside a vehicle or on a  
truck or trailer bed because interior carpets or plastic  
truck bed liners may insulate the container and slow  
the loss of any static charge.  
When practical, remove gas-powered equipment from  
the truck or trailer and refuel the equipment with its  
wheels on the ground.  
If this is not possible, then refuel such equipment on a  
truck or trailer from a portable container, rather than  
from a gasoline dispenser nozzle.  
If a gasoline dispenser nozzle must be used, keep the  
nozzle in contact with the rim of the fuel tank or  
container opening at all times until fueling is complete.  
WARNING  
POTENTIAL HAZARD  
Gasoline vapor can collect inside enclosed trailers and  
may be ignited by electrical sparks or hot  
engine/exhaust components.  
WHAT CAN HAPPEN  
Explosion and fire may occur, resulting in property  
damage, personal injury, and/or death.  
HOW TO AVOID THE HAZARD  
Provide adequate ventilation of any enclosed trailer to  
prevent build up of gasoline vapors, especially at floor  
level.  
Never refuel equipment inside an enclosed trailer.  
Be sure all fuel tanks and gasoline storage containers  
have proper caps installed to prevent spillage and  
minimize vapor escaping into the trailer.  
Do not place any equipment that is leaking gasoline in  
an enclosed trailer.

1.4 OPERATION  
Although hazard control and accident prevention are partially dependent upon the  
design and configuration of the equipment, these factors are also dependent upon  
the awareness, concern, prudence and proper training of the personnel involved in  
the operation, transport, maintenance and storage of the equipment. It is essential  
that all Operator Safety Mechanisms be connected and in operating condition prior  
to use for mowing.  
WARNING  
POTENTIAL HAZARD  
Operating engine parts, especially the muffler, become  
extremely hot.  
WHAT CAN HAPPEN  
Severe burns can occur on contact.  
Debris, such as leaves, grass, brush, etc. can catch fire.  
HOW TO AVOID THE HAZARD  
Allow engine parts, especially the muffler, to cool before  
touching.  
Remove accumulated debris from muffler and engine area.  
Install and maintain in working order a spark arrester before  
using equipment on forest-covered, grass-covered, or  
brush-covered unimproved land.  
WARNING  
POTENTIAL HAZARD  
Hands, feet, hair, clothing, or accessories can become  
entangled in rotating parts.  
WHAT CAN HAPPEN  
Contact with rotating parts can cause traumatic amputation  
or severe lacerations.  
HOW TO AVOID THE HAZARD  
Do not operate the machine without guards, shields, and  
safety devices in place and working.  
Keep hands, feet, hair, jewelry, or clothing away from  
rotating parts.  
1.4.1  
1.4.2  
Give complete, undivided attention to the job at hand.  
Mow only in daylight or good artificial light, keeping away from holes and hidden  
hazards. Do Not operate the mower when children or others are in the area!  
1.4.3  
When feasible, avoid operating the equipment in wet grass.  
- 4 -

1.4.4  
Use EXTREME caution when mowing and/or turning on slopes as loss of traction  
and/or control could occur. Mow across slopes with walk behind mowers, never  
up and down. Loss of control and/or loss of operator’s footing could result in a fall  
with an arm or leg getting under the mower or engine deck and sustaining serious  
injury. Drive slower on slopes. Progressively greater care is needed as the slope  
increases. DO NOT operate on slopes greater than 20 degrees. Watch for  
ditches, holes, rocks, dips, and rises, which can cause erratic handlebar  
movement and loss of footing. Keep away from drop-offs and steep banks. Avoid  
sudden starts. Look down and behind you before and while moving backwards.  
DO NOT mow slopes when grass is wet - slippery conditions create hazardous  
footing, affect steering, and reduce traction and braking. The operator is  
responsible for safe operation on slopes. See inside back cover to determine the  
approximate slope angle of the area to be mowed.  
1.4.5  
1.4.6  
Stop the blades when crossing surfaces other than grass, if mower must be tilted  
for transportation, and when transporting the mower to and from the area to be  
mowed.  
Never operate the mower with defective guards, shields, or covers. Always have  
safety shields, guards, switches, and other devices in place and in proper working  
condition.  
1.4.7  
1.4.8  
1.4.9  
Do Not change the engine governor settings or over-speed the engine. Operating  
an engine at excessive speed may increase the hazard of personal injury.  
Place speed control levers in neutral lock position, disengage PTO, and engage  
park brake before starting engine.  
Start the engine carefully with feet well away from blades.  
1.4.10 Keep hands, feet, and clothing away from rotating parts while the mower is being  
operated.  
1.4.11 Stop the engine and wait for all moving parts to stop. Remove plug wire(s) or  
remove ignition key:  
Before checking, cleaning, or working on the mower.  
After striking a foreign object (inspect the mower for damage and make  
repairs before restarting and operating the mower).  
1.4.12 Stop the engine and wait for all moving parts to stop:  
Before clearing blockages.  
Whenever you leave the mower.  
Before removing the grass catcher.  
Before refueling.  
Before making height adjustments.  
1.4.13 Before stopping the engine, return the throttle control to the idle position for about  
one minute to allow the engine to cool down.  
1.4.14 The fuel system is provided with a shut-off valve. The fuel shut-off valve is used to  
shut off the fuel when:  
The machine will not be used for a few days.  
During transport to and from the job.  
When parking inside a building.  
1.4.15 This mower was designed for one operator only. Keep all others away from mower  
during operation.  
1.4.16 Do Not mow without the grass deflector or entire grass collection system in place  
and in proper working condition.

1.4.17 Be aware of the mower discharge direction and do not point it at anyone.  
1.4.18 Do NOT operate the mower under the influence of alcohol or drugs.  
1.4.19 Use care when approaching blind corners, shrubs, trees, or other objects that may  
obscure vision.  
1.4.20 If jump starting is required: (Electric start units only)  
a) connect the positive (+) power cable from the positive post on the booster  
battery to the positive terminal post on the starter solenoid switch (this post  
has the positive battery cable attached to it).  
b) connect the negative or ground cable (-) from the negative post on the  
booster battery to the engine block as far away from the battery as possible.  
c) disconnect battery cables in the reverse order after starting.  
1.5 MAINTENANCE AND STORAGE  
1.5.1  
1.5.2  
1.5.3  
For engine maintenance, follow the engine manufacture’s recommendations  
precisely as stated in the engine manual.  
Disconnect the battery from the negative battery post when the unit will be allowed  
to sit for more than 30 days without use.  
Allowing batteries to stand for an extended period of time without recharging  
them will result in reduced performance and service life. To preserve optimum  
battery performance and life, recharge batteries in storage when the open circuit  
voltage drops to 12.4 volts.  
Note: To prevent damage due to freezing, battery should be fully charged before  
putting away for winter storage.  
1.5.4

grease, or oil and other debris, which can accumulate in these areas. These  
materials can become combustible and may result in a fire.  
1.5.5  
1.5.6  
Store fuel in a container specifically designed for this purpose in a cool, dry place.  
Keep the mower and fuel container in locked storage to prevent children from  
playing or tampering with them.  
1.5.7  
Gasoline powered equipment or fuel containers should not be stored in a  
basement or any enclosed area, where open pilot lights or heat appliances are  
present.  
1.5.8  
1.5.9  
Maximum mowing results and safety can only be achieved if the mower is properly  
maintained and operated correctly.  
Check all bolts frequently to maintain proper tightness.  
1.5.10 Keep all guards, shields, and all safety devices in place and in safe working  
condition.  
1.5.11 Frequently check for worn or deteriorating components that could create a hazard.

4. OPERATION INSTRUCTIONS  
4.1 Controls  
4.1.1  
Operator Presence Control (OPC) Levers: Located on the upperhandle assembly  
directly above the handle grips. When these levers are depressed, the OPC  
system senses that the operator is in the normal operator's position. When  
the levers are released, the OPC system senses that the operator has moved  
from the normal operating position and will kill the engine if either the speed  
control lever is not in the neutral position or the blade clutch is engaged.  
4.1.2  
4.1.3  
Speed Control Lever: Located in middle of control console, it controls the maximum  
forward speed and is infinitely variable from neutral (0 mph) to 6.2 mph.  
Drive Levers: Located on each side of the upper handle assembly directly below  
the handle grips (See Figure 7). These levers individually control the speed and  
direction of each drive wheel. When the speed control lever is moved out of the  
neutral position and the neutral lock latches are moved into the drive position, as  
shown in Figure 7, and the drive levers are released, the drive wheels are engaged  
in the forward direction.  
Squeezing the left hand and/or right hand lever causes the left hand and/or right  
hand drive wheel respectively to slow down, stop, or reverse, depending on how far  
each drive lever is "squeezed". Squeezing the drive levers beyond the neutral  
position causes the drive wheels to engage in the reverse direction regardless of the  
position of the neutral lock latches and the speed control lever.  
4.1.4  
Neutral Lock Latch: Located directly above the drive levers. These latches allow the  
operator to lock the drive levers in a "neutral" position where neither of the drive  
wheels are engaged in either a forward or reverse direction (See Figure 7).  
STANDARD PISTOL GRIP HANDLES

4.1.7  
4.1.8  
Throttle Control: Located on the control console’s right side. The throttle is used to  
control engine speed. Moving the throttle control forward will increase engine  
speed and moving it to the rear will decrease engine speed.  
“Off-Run” Switch (15 & 17 HP Kawasaki Manual Start only):  
Located on the console. Turn key to the “Run” position to allow the engine to be  
started. Turn key to the “Off” position to shut engine off.  
4.1.9  
Ignition Switch (17 HP Kawasaki Electric Start only):  
Located on the control console. The ignition switch starts and stops the engine.  
The switch has three positions “OFF”, “ON”, and “START”. Insert key into switch  
and rotate clockwise to the “ON” position. Rotate clockwise to the next position to  
engage the starter (key must be held against spring pressure in this position).  
When engine starts, release key.  
Operator must have speed control lever in neutral and blade engagement  
lever fully disengaged to start engine.  
4.1.10 Park Brake Lever: Located on the right side of the unit above the hydraulic tank.  
The brake lever engages the park brake on the drive wheels.  
Pull the lever up and rearward to engage the brake.  
Push the lever forward and down to disengage the brake.  
When parking on a steep slope, the wheels must be chocked or blocked in addition  
to the brake being engaged. The unit must be tied down and brake engaged when  
transporting.  
Park brake must be disengaged to move speed control out of neutral or engine will  
kill.  
4.1.11 Fuel Shut-Off Valve: Installed in the fuel line midway between the tank and the  
engine. The fuel shut-off valve is used to shut off the flow of fuel when parking  
inside a building, during transportation to and from the job sites, and when the  
machine will not be used for a few days.  
Rotate valve 1/4 turn clockwise to shut fuel off. Rotate valve 1/4 turn counter-  
clockwise to turn fuel on.  
4.1.12 Drive Wheel Release Valves: Located on the top rear corner of the hydrostatic  
pumps. Drive wheel release valves are use to release the hydro-static drive system  
to allow the machine to be moved by hand without the engine running. Turn valves  
one-half turn counterclockwise to release the drive system.  
Turn clockwise to reset the drive system. Do Not over-tighten.  
4.1.13 Cold Start Kit: (Manual start units only) Located on the right hand side of engine deck,  
below the hydro control shield. The cold start kit is used to ease the starting of the  
unit in cold weather or when the unit has not been operated for a period of time. The  
cold start kit moves the idler pulley away from the pump belt releasing the tension on  
the belt, which allows the engine to turn over with less resistance. See Section 4.3.2.  
4.1.14 Tracking Adjustment Knob: Located on the right-hand side of the rear of the fuel  
tank support. Can be adjusted so that machine will “track” straight ahead with  
drive levers released.  
4.2 Pre-Start  
4.2.1  
Fill fuel tank. For best results use only clean fresh regular grade unleaded  
gasoline with an octane rating of 87 or higher. Regular grade leaded gasoline may  
also be used; however, combustion chamber and cylinder head will require more  
frequent service. See Engine Owner's Manual.  
Do not add oil to gasoline.  
Never fill the fuel tank so that the fuel level rises above a level that is 1/2” below the  
bottom of the filler neck to allow for fuel expansion and prevent fuel spillage.

DANGER  
POTENTIAL HAZARD  
In certain conditions gasoline is extremely flammable and  
highly explosive.  
WHAT CAN HAPPEN  
A fire or explosion from gasoline can burn you, others, and  
cause property damage.  
HOW TO AVOID THE HAZARD  
DO NOT smoke while refueling, and stay away from an open  
flame or where gasoline fumes may be ignited by spark.  
Refuel only in a well ventilated area, or refuel outdoors.  
Store gasoline in an approved container and keep it out of the  
reach of children.  
Add fuel before starting the engine. Never remove the cap of  
the fuel tank or add fuel when engine is running or when the  
engine is hot.  
Never fill the fuel tank so that the gasoline level rises above a  
level that is 1/2” below the bottom of the filler neck to allow for  
gasoline expansion and prevent fuel spillage.  
If fuel is spilled, DO NOT attempt to start the engine. Move  
away from the area of the spill and avoid creating any source  
of ignition until fuel vapors have dissipated.  
DANGER  
POTENTIAL HAZARD  
In certain conditions gasoline is extremely flammable and  
highly explosive.  
WHAT CAN HAPPEN  
A static charge can ignite gasoline vapors. A fire or explosion  
from gasoline can burn you, others, and cause property  
damage.  
HOW TO AVOID THE HAZARD  
Purchase and store gasoline only in an approved container.  
Always place gasoline containers on the ground away from  
your vehicle before filling.  
Do not fill gasoline containers inside a vehicle or on a truck or  
trailer bed because interior carpets or plastic truck bed liners  
may insulate the container and slow the loss of any static  
charge.  
When practical, remove gas-powered equipment from the  
truck or trailer and refuel the equipment with its wheels on the  
ground.  
If this is not possible, then refuel such equipment on a truck or  
trailer from a portable container, rather than from a gasoline  
dispenser nozzle.  
If a gasoline dispenser nozzle must be used, keep the nozzle  
in contact with the rim of the fuel tank or container opening at  
all times until fueling is complete.

Change hydraulic system filter.  
Service Interval: After First 250 hrs, then yearly thereafter.  
Note: Use only Exmark Part No. 513211 for Summer use above 32° F (0° C) or  
Part No. 523541 for Winter use below 32° F (0° C). Refer to 2.7.2 for filter  
specifications.  
a) Place unit on a level surface, stop engine and wait for all moving parts to  
stop. Remove ignition key or spark plug wire(s).  
b) Carefully clean area around filter. It is important that no dirt or contamination  
enters the hydraulic system.  
c) Unscrew filter to remove and allow oil to drain from reservoir.  
IMPORTANT: Before re-installing new filter, fill it completely with Mobil 1  
15W-50 and apply a thin coat of oil on the surface of the rubber seal. Turn  
filter clockwise until rubber seal contacts the filter adapter. Do not tighten yet.  
d) Fill reservoir as stated in Section 5.1.8.  
e) Loosen filter 1/2 turn and allow a small amount of oil to leak from the oil filter  
(this allows air to be purged from the oil filter and supply hose from the  
hydraulic reservoir). Turn filter clockwise until rubber seal contacts the filter  
adapter. Then tighten the filter an additional 2/3 to 3/4 turn.  
f) Raise the rear of the machine up onto jack stands high enough to raise the  
drive wheels off of the ground. Run machine to allow any other air to be  
purged from the hydraulic system and recheck the oil level.  
g) If either drive wheel does not rotate, one or both of the charge pumps  
(located on the top of the main pump as shown in Figure 9) may have lost  
their “prime”. Refer to Section 5.1.10.  
h) DO NOT change hydraulic system oil (except what can be drained when  
changing filter) unless it is felt that oil has been contaminated. Changing oil  
unnecessarily could damage the hydraulic system by introducing  
contaminates into the system.  
5.1.10 Hydraulic system air purge procedure.  
Air must be purged from the hydraulic system when any hydraulic components,  
including the oil filter, are removed or any of the hydraulic lines are disconnected.  
The critical area for purging air from the hydraulic system is between the oil  
reservoir and each charge pump located on the top of each variable displacement  
pump (See Figure 9).  
Air in other parts of the hydraulic system will be purged through normal operation  
once the charge pumps are “primed”.  
a) Stop engine and wait for all moving parts to stop. Raise the rear of the  
machine up onto jack stands high enough to raise the drive wheels off the  
ground.  
b) Check oil level as stated in Section 5.1.8.  
c) Start engine and move throttle control ahead to full throttle position. Move the  
speed control lever to the middle speed position and place the drive levers in  
the “drive” position.  
If either drive wheel does not rotate, it is possible to assist the purging of the  
charge pump by carefully rotating the tire in the forward direction.  
NOTE: It is necessary to lightly touch the charge pump cap with your  
hand to check the pump temperature. If the cap is too hot to touch, turn  
off engine. The pumps may be damaged if the pump becomes too hot.  
If either drive wheel still does not rotate continue with step (d).

e) To “prime” charge pump, loosen two hex socket head capscrews (shown in  
Figure 11) 1-1/2 turns only. Make sure engine is not running. Lift charge  
pump housing upward and wait for a steady flow of oil to flow out from under  
housing. Retighten capscrews. Do this for both pumps. Note: Hydraulic  
reservoir can be pressurized to up to 5 psi to speed this process.  
f) If either drive wheel still does not rotate, stop and repeat Steps (d) through  
(e) above for the respective pump. If tires rotate slowly, the system may  
prime after additional running. Check oil level as stated in Section 5.1.8.  
g) Allow unit to run several minutes after the charge pumps are “primed” with  
drive system in the full speed position.  
Check oil level as stated in Section 5.1.8.

neutral, until left wheel stops rotating forward. Turn the rear nut an  
additional 1/2 turn and tighten the front nut making sure not to put a bind  
on the linkage. Make sure flat part of linkage is perpendicular to pin part  
of swivel. See Figure 15.  
FIGURE 15  
HYDRO CONTROL LINK/SWIVEL ADJUSTMENT  
After adjusting the left hydro control linkage, move the speed control lever  
to the mid-speed position and then back to the neutral position. Recheck  
the left drive wheel rotation to see if further adjustment is necessary - be  
sure the speed control lever is in the neutral position.  
If inconsistent neutral occurs, check to be sure both springs are  
properly tightened on the speed control lever under the console -  
especially the rear pivot spring.  
Repeat above adjustments if necessary.  
3. Place the speed control lever in neutral. Adjust the right side linkage by  
turning the quick track knob counter-clockwise until the tire begins to  
rotate forward. Begin to retighten the knob clockwise about 1/4 turn at a  
time, stopping to move the speed control forward and back to neutral.  
Recheck the drive wheel rotation to see if further adjustment is necessary.  
4. The spring that keeps tension on the knob should normally not need  
adjustment. However if adjustment is needed, adjust to where length of  
spring is about 1” between the washers. Adjust spring length by turning  
nut at front of spring.  
d) Drive Lever Linkage Adjustment  
1. With rear of machine still on jack stands and engine running at full  
throttle, move the speed control lever to the midway position. Move the  
respective drive lever upward until it reaches the neutral position and  
engage neutral lock latches. See Figure 16. If the tire rotates in either  
direction, the length of the drive lever link will need to be adjusted.  
2. For Standard Pistol Grip Handles: Adjust the linkage length by  
releasing the drive lever and removing clevis pin and rotating the linkage  
in the lower swivel. Lengthen the linkage if the tire is turning in reverse  
and shorten the linkage if the tire is creeping forward. Rotate the linkage  
several turns if the tire is rotating fairly fast. But as the adjustment gets  
closer, adjust the linkage in 1/2 turn increments. Release and re-engage  
neutral lock latch checking that the tire stops. Continue this process until  
the tire is at a dead stop. Replace the hairpin back into each clevis pin.  
For ECS Handles: Adjust the linkage length by loosening the jam nuts at  
both ends of the linkage and rotating the linkage in the ball joints.  
Lengthen the linkage if the tire is turning in reverse and shorten the  
linkage if the tire is creeping forward. Tighten the jam nuts at both ends.  
Release and re-engage the neutral lock latch checking that the tire stops.  
Continue this process until the tire is at a dead stop.

3. Make this adjustment for both sides.  
e) Tracking Adjustment  
1. Stop engine and wait for all moving parts to stop. Raise the rear of the  
machine, remove jack stands and carefully lower the machine to the  
ground. (Check the drive tire pressure and tire circumference. See  
5.1.11.)  
2. Run the unit and observe the tracking on a level, smooth, hard surface  
such as concrete or asphalt.  
3. If the unit tracks to one side or the other, turn the quick track knob. Turn  
the knob right to “steer” right; turn the knob left to “steer” left.  
5.2.7 Hydro Pump Spring Tension Setting  
a) For medium or heavy duty drive conditions such as operation with a sulky on  
steep slopes, a higher spring force may be required on the hydro pump  
control arms to prevent the drive system from stalling.  
b)  
For a heavier drive setting, relocate the spring anchor link to either the  
“medium” or “heavy duty” positions as shown in Figure 17. The spring  
anchor links are attached to the upper rear corner of the hydro drive shields  
on the left and right hand sides of the machine.  
Note: In the “medium” or “heavy duty” positions, the drive lever forces at  
the upper handle will also be increased.

6. WASTE DISPOSAL  
6.1 MOTOR OIL DISPOSAL  
Engine oil and hydraulic oil are both pollutants to the environment. Dispose of used oil at a  
certified recycling center or according to your state and local regulations.

6.2 BATTERY DISPOSAL  
DANGER  
POTENTIAL HAZARD  
Battery electrolyte contains sulfuric acid, which is  
poisonous and can cause severe burns  
WHAT CAN HAPPEN  
Swallowing electrolyte can be fatal or if it touches skin  
can cause severe burns.  
HOW TO AVOID THE HAZARD  
Wear safety glasses to shield eyes, and rubber gloves  
to protect skin and clothing when handling electrolyte.  
Do not swallow electrolyte.  
Federal law states that batteries should not be placed in the garbage. Management and  
disposal practices must be within relevant federal, state, or local laws.  
If a battery is being replaced or if the unit containing the battery is no longer operating and is  
being scrapped, take the battery to a local certified recycling center. If no local recycling is  
available return the battery to any certified battery reseller.  
7. TROUBLE SHOOTING  
7.1 MOWER TRACKS TO LEFT OR RIGHT.  
a)  
b)  
Check the drive tire pressure and tire circumference. See 5.1.11.  
Turn knob on the right hydro control linkage in the direction that the mower  
needs to be adjusted to. Turn the knob in 1/4 turn increments until the  
mower tracks correctly.  
7.2 MOWER CUTS UNEVENLY.  
a) Check the drive tire pressure and tire circumference. See 5.1.11.  
A more uniform cutting height may be obtained with higher tire pressure on  
rough terrain. A lower tire pressure provides more flotation.  
b) Check deck support pins. Hairpin clips must be in the same hole position on  
each support pin. See Section 5.2.1  
c) Check deck support alignment and check mounting brackets to be sure all  
bolts are tight.  
d) Check blades tip to tip for straightness. (They should be within 3/16”, or one  
blade width from being in line.)  
7.3 ENGINE WILL NOT START.  
a) Make sure battery has a full charge (Electric start only). (See section 5.1.23)  
b) Check that choke is in the “ON” position for a cold engine or in the “OFF”  
position for a warm engine. See 4.3.2.  
NOTE: Kawasaki engines may need to be choked even when warm.  
c) Make sure the key switch is in the “ON” position (15 & 17 HP Kawasaki  
Manual start).  
d) Make sure the speed control lever is in the “true neutral” position. (See  
section 5.2.6)  
e) Check that the PTO is disengaged and the PTO switch is depressed.  
f) Make sure the OPC levers are depressed. (Electric start only)  
g) Check that there is fuel in the tank and that the fuel valve is open.

h) Check that the spark plug wire(s) are properly connected.  
i) Check for loose or faulty wiring connections. If it is necessary to disconnect  
wire connectors, Do Not pull on the wires while disconnecting.  
j) Check for corrosion at all wiring connections. Even minor corrosion may  
cause a faulty connection. Clean connector terminals thoroughly with  
electrical contact cleaner, apply dielectric grease and reconnect.  
IMPORTANT: It is essential that all operator safety mechanisms be  
connected and in proper operating condition prior to mower use.  
NOTE: After carefully checking the above steps, attempt to start the engine. If  
it does not start, contact your authorized Exmark service dealer.  
ENGINE TROUBLESHOOTING  
When a problem occurs, do not overlook the simple causes. For example, starting  
problems could be caused by an empty fuel tank.  
The following table lists some of the common causes of trouble.  
Do not attempt to service or replace major items or any items that call for special  
timing or adjustment procedures (such as valves, governor, etc.). Have this work  
done by your Engine Service Dealer.
