EXMARK PARTS PLUSÒ PROGRAM
EFFECTIVE DATE: September 1, 1995
Program
If your Exmark dealer does not have the Exmark part in stock,
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 PlusÒ 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 PlusÒ order, he contacts Exmark by 3:00 p.m.,
central time, with an Exmark Parts PlusÒ 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 PlusÒ 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 PlusÒ 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 PlusÒ 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 PlusÒ Program is available only through participating Exmark
Dealers and applies only to orders submitted on this program Monday through Thursday. Parts Plus service is only available
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 PlusÒ 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 PlusÒ Program are: Any wholegood or accessory in its
entirety, engines and engine replacement parts, 5-speed Peerless transmissions and 5-speed transaxles, hydraulic or

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.

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.

DANGER
POTENTIAL HAZARD
¨
Mowing on wet grass or steep slopes can cause sliding and
loss of control.
WHAT CAN HAPPEN
¨
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, which may result in serious injury or death.
HOW TO AVOID THE HAZARD
¨
¨
¨
¨
¨
¨
Mow across slopes, never up and down.
Do not mow slopes when grass is wet.
Do not mow near drop-offs or near water.
Do not mow slopes greater than 20 degrees.
Reduce speed and use extreme caution on slopes.
Avoid sudden turns or rapid speed changes.
·
See inside the back cover to determine the approximate slope angle of the
area to be mowed.
·
·
Progressively greater care is needed as the slope increases.
Always avoid sudden starting or stopping on a slope. If tires lose traction,
disengage the blades and proceed slowly off the slope.
·
Be aware that loss of traction may occur going downhill. Weight transfer to
the front wheels may cause drive wheels to slip and cause loss of braking
and steering.
·
·
·
Watch for ditches, holes, rocks, dips, and rises that change the operating
angle, as rough terrain could overturn the machine.
Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing
area. Tall grass can hide obstacles.
Use extreme care with grass catchers or attachments. These can change the
stability of the machine and cause loss of control.

4. OPERATION INSTRUCTIONS
4.1 Controls
4.1.1 Operator Presence Control (OPC) Levers: Located on the upper handle
assembly directly above the handle grips. See Figure 3. 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
PTO is engaged.
4.1.2 Drive Levers: Located on each side of the upper handle assembly directly below
the handle grips. See Figure 3. 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 3, 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.
4.1.3 Neutral Lock Latches: These latches allow the operator to lock the drive levers in a
“neutral” position where the drive wheels are not engaged in either a forward or
reverse direction. See Figure 3.

Check the battery charge.
Allowing the batteries to stand for an extended period 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.
Check the voltage of the battery with a digital voltmeter. Locate the voltage
reading of the battery in the table below and charge the battery for the
recommended time interval to bring the charge up to a full charge of 12.6 volts or
greater.
IMPORTANT: Make sure the negative battery cables are disconnected and the
battery charger used for charging the battery has an output of 16 volts and 7
amps or less to avoid damaging the battery (see chart below for recommended
charger settings).

Check hydraulic oil level.
Service Interval: 40 hr.
a)
b)
c)
Stop engine and wait for all moving parts to stop.
Clean area around hydraulic reservoir cap and remove cap.
Check hydraulic reservoir and if necessary fill the reservoir to the
appropriate level with Mobil 1 15W-50 synthetic motor oil. Replace
hydraulic reservoir cap and tighten until snug. Do not overtighten.
NOTE: The baffle is labeled “HOT” and “COLD”. The oil level varies with the
temperature of the oil. The “HOT” level shows the level of oil when it is at
225°F (107°C). The “COLD” level shows the level of the oil when it is at 75°F
(24°C). Fill to the appropriate level depending upon the temperature of the
oil. For example: If the oil is about 150°F (65°C), fill halfway between the
“HOT” and “COLD” levels. If the oil is at room temperature (about 75°F
(24°C)), fill only to the “COLD” level.
5.1.10 Change hydraulic system filter.
Service Interval: After First 250 hrs, then yearly thereafter.
Note: Use only Exmark P/N 1-513211 for Summer use above 32° F (0° C) or P/N
1-523541 for Winter use below 32° F (0° C). (Refer to Section 2.6.2 for filter
specifications)
a)
b)
c)
Place unit on a level surface. Stop engine, wait for all moving parts to stop,

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 5.1.9.
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)
h)
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 6) may have lost
their “prime”. Refer to Section 5.1.11.
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.
5.1.11 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”.

Thoroughly clean the area around each of the charge pump housings.
To “prime” charge pump, loosen two hex socket head capscrews (shown in
Figure 7) 1-1/2 turns only. Make sure engine is not running. Lift the
charge pump housing upward and wait for a steady flow of oil to flow out
from under the housing. Retighten the capscrews. Do this for both pumps.
Note: Hydraulic reservoir can be pressurized up to 5 psi to speed this process.
f)
If either drive wheel still does not rotate, stop and repeat steps (d) and (e)
above for the respective pump. If wheels rotate slowly, the system may
prime after additional running. Check oil level as stated in Section 5.1.9.
g)
h)
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

CAUTION
POTENTIAL HAZARD
¨
When mower deck is not installed or the two front
support rod hairpins are removed, the unbalanced
weight of the tractor or tractor with mounted mower
deck support frame may cause the front of the unit to
rise suddenly.
WHAT CAN HAPPEN
If the unit rises suddenly, injury may occur.
HOW TO AVOID THE HAZARD
¨
¨
Securely hold down the front end of the unit when the
mower deck is not installed or front support rod
hairpins are removed.
a)
b)
Stop engine and wait for all moving parts to stop.
Install hairpin clips in the holes for the desired cutting height. See Figure 9.
IMPORTANT: To maintain correct cutting height and rake, check the following
for proper adjustment.
1. The front and rear hairpins are in the same holes with the proper spacers
under the hair pins. See Figure 9.
2. The tire pressures are set as directed in Section 5.1.12.
3. The length of the rear deck support link assemblies should average 6.89”
(approximately 6 7/8” (17.5 cm)) from the center of the balljoint to the
center of the farthest hole. See Figure 9.
NOTE: All (4) pins must equally support the weight of the deck.
Adjustment in the length of the rear deck support assemblies may be
necessary. If one side is longer than 6.89” (17.5 cm), than the opposite

1. Stop engine and wait for all moving parts to stop.
2. Move speed control lever (located on console) to the full forward position
and check orientation of tabs on the ends of the speed control crank. See
Figure 11. These tabs should be pointing straight down at the 6 o’clock
position or slightly forward. Adjust threaded yoke at the bottom of speed
control linkage until tabs are positioned correctly. See Figure 11.
3. Pull 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 Figure 11. If
necessary, move the switch fore and aft.
FIGURE 11
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 “forward” position as shown in
Figures 4 & 5 and move the speed control lever to the “mid-speed”
position.
Note: The park brake must be disengaged and 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.
For Standard Pistol Grip Models: 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 wheels stop then go to step 7.

HYDRO DRIVE LINKAGE ADJUSTMENT
4. Loosen the nut against the neutral control linkage yoke as shown in
Figure 12.
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 lever is
in the neutral position, tighten the nut against the yokes.
c) Adjust Hydro Control Linkage:
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 lever is moved out of neutral position.
Note: The neutral lock latches should still be “unlocked” and in the
“forward” position.
2. Loosen the front nut on left hydro control link as shown in Figure 13. Turn
the rear control linkage adjusting nut counter-clockwise until wheel rotates
forward. Turn the rear nut of left control link 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 nut an additional 1/2 turn and
tighten the front jam 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 12.

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” (2.5 cm) between 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 14. If the tire rotates in either
direction, the length of the drive lever linkage 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 these 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 checking that the tire stops.
Continue this process until the tire is at a dead stop.
