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.

WARNING  
POTENTIAL HAZARD  
Engine exhaust contains carbon monoxide, which is  
an odorless deadly poison.  
WHAT CAN HAPPEN  
Carbon monoxide can kill you and is also known to the  
State of California to cause birth defects.  
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.  
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.  
1.4.1  
1.4.2  
Give complete, undivided attention to the job at hand.  
Do Not  
Mow only in daylight or good artificial light.  
children or others are in the area!  
operate the mower when  
1.4.3  
1.4.4  
When feasible, avoid operating the equipment in wet grass.  
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  
DO NOT  
and sustaining serious injury. Drive slower on slopes.  
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  
DO NOT  
behind you before and while moving backwards.  
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.

4. OPERATION INSTRUCTIONS  
4.1 Controls  
4.1.1 Operator Presence Control (OPC) Levers: Located on the upper handle  
When these levers are depressed,  
assembly directly above the handle grips.  
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  
position or the  
not in the neutral  
engine if either the speed control lever is  
blade clutch is engaged  
.
4.1.2 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.  
4.1.3 Drive Levers: Located on each side of the upper handle assembly directly  
below the handle grips (See Figure 5). 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 5, 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 5).  
FIG. 5  
DRIVE LEVER, NEUTRAL LOCK LATCH OPERATION  
4.1.5 Blade Engagement: The “push/pull” blade engagement knob is located on the  
left side of the control console. To engage the blades, the knob must be pulled  
toward the operator until the turnbuckle (attached to the blade engagement  
idler) locks over-center. To disengage the blades, push the knob down until the  
assist arm contacts the pin on the deck.  
4.1.6 Throttle-Choke Control: The throttle-choke control lever is located on the  
control console right side. Choke aids in starting a cold engine. The choke  
control is a part of the throttle control and activates by moving the throttle  
control lever to the full forward position. You will notice a detent at the “full  
throttle” position (approximately 3/4” from top of slot) continue pushing forward  
into the “choke” position.

Once the engine has started, move the throttle control lever to the midway  
point and allow the engine to warm-up before going to full throttle.  
4.1.7 “Off-Run” Switch: 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.  
4.1.8 Fuel Shut-Off Valve: Installed in the fuel line midway between the tank and  
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.  
4.1.9 Drive Wheel Release Valves: Located on the top rear corner of the hydrostatic  
pumps. Drive wheel release valves are used 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.  
Do Not over-tighten.  
Turn clockwise to reset the drive system.  
4.1.10 Cold Start Kit: Located on the right hand side of engine deck, below and  
slightly ahead of 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.  
4.1.11 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.

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.

(located on the top of the main pump as shown in Figure 7) may have lost  
their “prime”. Refer to Section 5.1.10.  
DO NOT  
h)  
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 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 7).  
Air in other parts of the hydraulic system will be purged through normal  
operation once the charge pump is “primed”.  
a) Stop engine. 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 an move throttle control ahead to full throttle position. Move  
the speed control lever to the middle speed position and place the drive  
levers into 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).  
d) Thoroughly clean the area around each of the charge pump housings.

5.2.1  
Blade Spacers:  
Blades may be adjusted for cutting height by using the four 1/4" spacers found  
on the blade spindle bolts (factory setting is two above and two below). This  
allows a 1" range in 1/4" increments of cutting height in any axle position. The  
same number of blade spacers must be used on all blades to achieve a level  
cut (two above and two below, one above and three below, etc.).  
For the best cut and discharge a minimum of two spacers should be placed  
between the blade and spindle shaft. The highest quality cut can be achieved  
with all four spacers between the blade and the spindle shaft.  
If the mulching kit is installed, the highest quality cut can be obtained with 3  
spacers between the blade and spindle (minimum is 1 for a good cut).  
If you need to cut higher or lower than what the spacers will allow, it will be  
necessary to adjust the rear axle height and caster position. See Section 5.2.2  
below.  
5.2.2  
Axle height and caster spacer position:  
Desired cutting height range can be obtained by adjusting the rear axle and  
placing caster spacers above or below the caster arm (See Figure 8).  
To adjust rear axle:  
a) Stop engine and remove spark plug wire(s).  
b) Raise the rear of the machine up onto jack stands and remove the drive  
wheels.  
CAUTION  
POTENTIAL HAZARD  
Raising the mower deck for service or maintenance  
relying solely on mechanical or hydraulic jacks could  
be dangerous.  
WHAT CAN HAPPEN  
The mechanical or hydraulic jacks may not be enough  
support or may misfunction allowing the unit to fall,  
which could cause injury.  
HOW TO AVOID THE HAZARD  
DO NOT rely solely on mechanical or hydraulic jacks  
for support. Use adequate jack stands or equivalent  
support.

c) Be sure the bellcrank  
touch the switch body or damage to  
the switch could occur.  
d) Retighten switch blade mounting bracket.  
5.2.5 Engine to Cutter Deck Belt:  
a) Stop engine and remove spark plug wire(s).  
b) Check belt guides under rear engine and front mower deck to see that  
they are properly set (See Section 5.2.6).  
c) Belt must be tight enough so it does not slip during heavy loads while  
cutting grass. Over-tensioning will reduce belt and spindle bearing life. To  
adjust belt tension, loosen the 5/16" whizlock nut on turnbuckle and  
rotate the turn buckle; rotate turnbuckle toward rear of mower to tighten,  
and toward front of mower to loosen belt tension (See Figure 10).  
For 48” Decks: If there is no adjustment left in the turnbuckle and the  
belt is still loose, the rear idler pulley can be repositioned in the front hole  
(See Figure 10). The belt guide located next to the pulley must also be  
repositioned in the front hole when the pulley is moved. The turnbuckle  
will need to be readjusted.  
Check belt tension after the first hour of operation and at least twice  
during the first 24 hours of operation. Adjust as necessary.  
Note: After readjusting the belt tension check the belt guide adjustment  
Section 5.2.7 and blade brake adjustment Section 5.2.6.

5.2.9 Hydro Drive Linkage Adjustment:  
a) Adjust Speed Control Linkage and neutral safety switch  
1. Move the speed control lever (located on the console) to the full  
forward position and check the orientation of the tabs on the ends of  
the speed control crank (Fig. 15). These tabs should be pointing  
straight down at the 6 o’clock position or slightly forward. Adjust the  
threaded yoke at the bottom of the speed control link until the tabs  
are positioned correctly.  
2. Pull the speed control lever back to neutral. Check that the neutral  
safety switch actuating tab has depressed the plunger of the switch  
so that there is about 5/16” between the tab and the switch. See fig.  
14. If necessary, move the switch fore and aft.  
FIG. 14  
NEUTRAL SAFETY SWITCH ADJUSTMENT  
b) Adjust Neutral Control Linkages  
1. Raise the rear of the machine up onto jack stands high enough to  
raise the drive wheels off of the ground.  
2. Start the engine and move the throttle ahead to the full throttle  
position. Place the neutral lock latches in the drive position as shown  
in Figure 6 and move the speed control lever to the “mid-speed”  
position.  
Note: The OPC levers must be held down whenever the speed  
control lever is out of the neutral position or the engine will kill.  
3. Squeeze the respective drive lever until an increased resistance is  
felt, this is where neutral should be.  
- 29 -  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Make sure you have not reached the end of the neutral lock latch slot.  
If you have, shorten the drive lever linkage. If the wheel turns while  
holding the drive lever in neutral, the neutral control linkages need to  
be adjusted. If wheel stop then go to step 7.  
FIG. 15  
HYDRO DRIVE LINKAGE ADJUSTMENT  
4. Loosen the nut against the neutral control linkage yoke as shown in  
Figure 15.  
5. Adjust the neutral control linkage until the respective drive wheel  
stops when the lever is pulled against the neutral spring (neutral  
position). Turn the adjusting bolt approximately 1/4 turn clockwise if  
the wheel is turning in reverse or turn the bolt approximately 1/4 turn  
counter-clockwise if the wheel is turning forward. Release the drive  
lever to the forward drive position and squeeze back into the neutral  
position. Check to see if the wheel stops. If not, repeat the above  
adjustment procedure.  
6. Make this adjustment on both sides.  
7. After adjustments are made and the wheels stop when the drive  
levers are in the neutral position, tighten the nuts against the yokes.  
c) Adjust Hydro Control Linkages:  
1. Place the speed control lever in the “neutral” position. This  
adjustment is again made with rear of machine on jack stands and  
engine running at full throttle. OPC levers will have to be held down  
whenever speed control levers are moved out of the neutral position.  
2. Loosen the front nut on left hydro control linkage as shown in Figure  
15. Turn the rear control linkage adjusting nut counter-clockwise until  
wheel rotates forward. Turn the rear nut of left control linkage  
clockwise 1/4 of a turn at a time, stopping to move the speed control  
forward and back to 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 Fig. 16.  
FIG. 16  
HYDRO CONTROL LINK/SWIVEL ADJUSTMENT  
- 30 -  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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  
neutral  
respective drive lever upward until it reaches the  
position and  
engage neutral lock latches. See fig. 17. If the tire rotates in either  
direction, the length of the drive lever link will need to be adjusted.  
2. 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 these process until the  
tire is at a dead stop.  
FIG. 17  
DRIVE LEVER AND LATCH IN NEUTRAL POSITION  
3. Replace the hairpin back into each clevis pin.  
4. Make this adjustment for both sides.  
e) Tracking Adjustment  
1. Stop engine, Raise the rear of the machine, remove jack stands and  
carefully lower the machine to the ground.  
2. Check the drive tire pressures and tire circumferences. See 5.1.11.  
3. Run the unit and observe the tracking on a level, smooth, hard  
surface such as concrete or asphalt.

Turn the knob right to “steer” right, turn the knob left to “steer” left.  
5.2.10 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 links to either the  
“medium” or “heavy duty” positions as shown in Figure 18. 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.

6.1 MOWER TRACKS TO LEFT OR RIGHT.  
a) Check the drive tire pressures and circumferences. See 5.1.11.  
b) Turn knob on the right hydro control linkage in the direction in which the  
mower needs to be adjusted. Turn the knob in 1/4 turn increments until  
the mower tracks correctly.  
6.2 MOWER CUTS UNEVENLY.  
a) Check the drive tire pressures and circumferences. 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 blade spacers, they must be equal on each blade.  
c) Check caster 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.)  
6.3 BLADES DO NOT STOP WHEN DISENGAGED.  
a) Check the blade brake adjustment. (See Section 5.2.6)  
b) Check the belt guide under rear deck to make sure they are properly set  
(See Section 5.2.7) and check the blade engagement adjustment (See  
Section 5.2.3.).  
6.4 ENGINE WILL NOT START.  
a) Check that the key switch is in the “Run” position.  
b) Check that the 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 speed control lever is in the “true neutral” position. (See 5.2.9).  
d) Check that the blades are disengaged and the blade switch is depressed.
