Safety
DANGER
DANGER
In certain conditions gasoline is extremely
flammable and vapors are explosive.
A fire or explosion from gasoline can burn
you, others, and cause property damage.
In certain conditions during fueling, static
electricity can be released causing a spark
which can ignite gasoline vapors. A fire or
explosion from gasoline can burn you and
others and cause property damage.
• Fill the fuel tank outdoors in an open
area, when the engine is cold. Wipe up
any gasoline that spills.
• Always place gasoline containers on the
ground away from your vehicle before
filling.
• Never refill the fuel tank or drain the
machine indoors or inside an enclosed
trailer.
• 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.
• Do Not fill the fuel tank completely
full. Add gasoline to the fuel tank until
the level is 1/4 to 1/2 inch (6–13 mm)
below the bottom of the filler neck. This
empty space in the tank allows gasoline
to expand.
• When practical, remove gas-powered
equipment from the truck or trailer and
refuel the equipment with its wheels on
the ground.
• Never smoke when handling gasoline,
and stay away from an open flame or
where gasoline fumes may be ignited by
spark.
• 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.
• Store gasoline in an approved container
and keep it out of the reach of children.
• 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.
• 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.
WARNING
• 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.
Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors has caused
cancer in laboratory animals. Failure to use
caution may cause serious injury or illness.
• Do Not operate without entire exhaust
system in place and in proper working
condition.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas
tank/container opening.
• Keep away from eyes and skin.
• Never siphon by mouth.
• Check that the operator’s presence controls,
safety switches, and shields are attached and
functioning properly. Do Not operate unless they
are functioning properly.
6
Safety
Operation
• Be sure all drives are in neutral and parking brake
is engaged before starting engine. Use seat belts
with the roll bar in the raised and locked position.
• Never operate the mower with damaged guards,
shields, or covers. Always have safety shields,
guards, switches and other devices in place and in
proper working condition.
• Never mow with the discharge deflector raised,
removed or altered unless there is a grass
collection system or mulch kit in place and
working properly.
• Do Not change the engine governor setting or
overspeed the engine.
• Stop engine, wait for all moving parts to stop,
remove key and engage parking brake:
– Before checking, cleaning or working on the
mower.
– After striking a foreign object or abnormal
vibration occurs (inspect the mower for
damage and make repairs before restarting
and operating the mower).
– Before clearing blockages.
– Whenever you leave the mower.
• Stop engine, wait for all moving parts to stop, and
engage parking brake:
– Before refueling.
– Before dumping the grass catcher.
WARNING
Operating engine parts, especially the
muffler, become extremely hot. Severe burns
can occur on contact and debris, such as
leaves, grass, brush, etc. can catch fire.
• 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
Engine exhaust contains carbon monoxide,
which is an odorless deadly poison that can
kill you.
Do Not run engine indoors or in a small
confined area where dangerous carbon
monoxide fumes can collect.
WARNING
Operating a FrontRunner tractor without an
approved Exmark front mount attachment
increases the possibility of forward tip over.
Tip-over could cause serious injury or death.
WARNING
Hands, feet, hair, clothing, or accessories can
become entangled in rotating parts. Contact
with the rotating parts can cause traumatic
amputation or severe lacerations.
When operating a FrontRunner tractor
without an approved Exmark front mount
attachment, observe the following:
• Do Not operate the machine without
guards, shields, and safety devices in
place and working properly.
• Limit operation to minimum required to
install a different front mount attachment.
• Keep hands, feet, hair, jewelry, or clothing
away from rotating parts.
• Minimize speed and use extreme caution.
• Only operate on a flat level surface.
• NEVER carry passengers. DO NOT operate
the mower when people, especially children, or
pets are in the area.
• Be alert, slow down and use caution when making
turns. Look behind and to the side before
changing directions.
• Do Not operate up or down a trailer ramp.
• Avoid sudden acceleration or deceleration.
• Operate only in daylight or good artificial light,
keeping away from holes and hidden hazards.
7
Safety
• Stop the blades, slow down, and use caution when
crossing surfaces other than grass and when
transporting the mower to and from the area to
be mowed.
• Be aware of the mower discharge path and direct
discharge away from others.
• Do Not operate the mower under the influence
of alcohol or drugs.
• Use extreme care when loading or unloading the
machine into a trailer or truck.
• Use care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.
Figure 3
Slope Operation
1. Safe Zone-Use the mower here on slopes less than 15
degrees
2. Danger Zone-Use a walk behind mower and/or hand
trimmer on slopes greater than 15 degrees, near
drop-offs and water.
3. Water
Use Extreme caution when mowing and/or turning
on slopes as loss of traction and/or tip-over could
occur. The operator is responsible for safe operation
on slopes.
DANGER
• Remove or mark obstacles such as rocks, tree
limbs, etc. from the mowing area. Tall grass can
hide obstacles.
Operating on wet grass or steep slopes can
cause sliding and loss of control. Wheels
dropping over edges, ditches, steep banks, or
water can cause rollovers, which may result
in serious injury, death or drowning.
• Watch for ditches, holes, rocks, dips and rises that
change the operating angle, as rough terrain could
overturn the machine.
• Avoid sudden stops when mowing downhill
because the mower may tip forwards.
• Do Not mow slopes when grass is wet.
• Do Not mow near drop-offs or near water.
• Be aware that operating on wet grass, across steep
slopes or down hill may cause the mower to lose
traction. Loss of traction to the drive wheels may
result in sliding and loss of braking and steering.
• Do Not mow slopes greater than 15
degrees.
• Reduce speed and use extreme caution
on slopes.
• Always avoid sudden starting or stopping on a
slope. If tires lose traction, disengage the blades
and proceed slowly off the slope.
• Avoid sudden turns or rapid speed
changes.
• Keep the roll bar in the raised and locked
position and use seat belt.
• Follow the manufacturer’s recommendations for
wheel weights or counter weights to improve
stability.
• See inside the back cover to determine the
approximate slope angle of the area to be mowed.
• Use extreme care with grass catchers or
attachments. These can change the stability of the
machine and cause loss of control.
• Use a walk behind mower and/or a hand trimmer
near drop-offs, ditches, steep banks or water.

of the unit.
1. Move the motion control levers inward to the
center to the neutral unlocked position.
2. To move rearward in a straight line applying equal
pressure pull both motion control levers rearward.
• If individual ramps must be used, use
enough ramps to create an unbroken
ramp surface wider than the unit.
To turn left or right, release pressure on the
motion control lever toward the direction desired.
• Do Not exceed a 15° angle between ramp
and ground or between ramp and trailer
or truck.
3. To stop, push the motion control levers to the
neutral position.
• Avoid sudden acceleration while driving
unit on a ramp.
22
Operation
Loading a Unit
Use extreme caution when loading units on trailers
or trucks. One full width ramp is required. If it is
not possible to use one full width ramp, use enough
individual ramps to simulate a full width continuous
ramp.
Ramp should be long enough so that the angles
between the ramp and the ground and the ramp and
the trailer or truck do not exceed 15°. A steeper angle
may cause mower deck components to get caught as
the unit moves from ramp to trailer or truck. Steeper
angles may also cause the unit to tip. If loading on or
near a slope, position the trailer or truck so it is on
the down side of the slope and the ramp extends up
the slope. This will minimize the ramp angle. The
trailer or truck should be as level as possible.
Important: Do Not attempt to turn the unit
while on the ramp, you may lose control and
drive off the side.
Avoid sudden acceleration when driving on a ramp.

4. To adjust the weight transfer springs, fold
the mower deck and front frame and lock in
service position. See Deck Manual for complete
instructions.
10. Stop engine and wait for all moving parts to stop.
Remove jumper wire from wire harness connector
and plug connector into seat switch.
WARNING
11. Lower from jackstands.
Weight transfer springs may have stored
energy. Removing the weight transfer
springs without releasing the stored energy
can cause serious injury.
Weight Transfer Spring
Adjustment
Fold mower deck and front frame and lock in
service position to remove spring tension and
release stored energy before performing any
maintenance or adjustments on the weight
transfer springs. (See Deck Manual for Deck
Raising instructions).
Weight transfer springs are assembled from the
factory to apply the maximum amount of weight onto
the drive wheels. This setting provides the greatest
amount of traction. Some conditions may require
the rear wheel lift to be reduced. This can be done
by reducing the amount to weight transfer, which
will increase the amount of weight on the front and
rear casters.
5. Remove the retaining ring and washer at either
end of the weight transfer spring that retains it to
the transfer bellcrank pins and/or weight transfer
spring anchor pins (see Figure 16).
1. Rotate the left motion control arm up and into
the operation position.
2. Locate and loosen the knob under the rear of the
left fender (see Figure 15).
6. Pull the spring off of front or rear pin and
re-install in the outer hole, to reduce the spring
force. Re-install the washer and retaining ring.

Maintenance
Clutch Shim
Some later model year units have been built with
clutches that contain a brake shim. When the clutch
brake has worn to the point where the clutch no
longer engages consistently, the shim can be removed
to extend the clutch life.

Maintenance
3. Check the condition of the wire harness leads,
connectors, and terminals. Clean or repair as
necessary.
4. Verify that 12V is present at the clutch connector
when the PTO switch is engaged.
5. Measure the gap between the rotor and armature.
If the gap is greater than .04 inch (1 mm), proceed
with the following steps:
A. Loosen both brake mounting bolts one-half
to one full turn as shown below.
C. Using a pneumatic line, blow out any debris
from under the brake pole and around the
brake spacers.
D. Re-torque each bolt (M6 x 1) to 10 ft-lb (13
N-m) +/-0.5 ft-lb (0.7 N-m).
E. Using a 0.010 inch thick feeler gauge, verify
that a gap is present between the rotor and
armature face on both sides of the brake pole
as shown. (Due to the way the rotor and
armature faces wear (peaks and valleys) it is
sometimes difficult to measure the true gap.)
Note: Do Not remove the brake pole from
the field shell/armature. The brake pole has
worn to match the armature and needs to
continue to match after the shim is removed
to ensure proper brake torque.
Figure 22
1. Feeler gauge

B. Using needle nose pliers, or by hand, take
hold of the tab and remove the shim (Do Not
discard the shim until proper clutch function
has been confirmed).
Figure 23
1. Feeler gauge
• If the gap is less than 0.010 inch, then
reinstall the shim and reference the
Troubleshooting section.
• If the gap is sufficient, proceed to the
safety check in step F.
F. Perform the following safety check:
a. Sit on the seat and start the engine.
b. Make sure the blades Do Not engage
with the PTO switch “off ” and the clutch
disengaged.

Waste Disposal
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.
Battery Disposal
DANGER
Battery electrolyte contains sulfuric acid,
which is poisonous and can cause severe
burns. Swallowing electrolyte can be fatal or
if it touches skin can cause severe burns.
• 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.

Conditions and Products Covered
Exmark Mfg. Co. Inc. and its affiliate, Exmark Warranty
Company, pursuant to an agreement between them, jointly
warrant on the terms and conditions herein, that we will repair,
replace or adjust any part on these products and found by us
(in the exercise of our reasonable discretion) to be defective in
factory materials or workmanship for a period of two years.
This warranty applies to Exmark commercial turf equipment
sold in the U.S. or Canada. This warranty may only be
assigned or transferred to a second (or third) owner by an
authorized Exmark dealer. The warranty period commences
upon the date of the original retail purchase.
Warranty Exceptions
• Bags, Belts and Tires
• Battery
• Engine
Owner’s Responsibilities
The Exmark turf equipment, including any defective part,
must be returned to an authorized Exmark service dealer
within the warranty period. This warranty extends only to turf
equipment operated under normal conditions. You must read
the operator’s manual. You must also properly service and
maintain your Exmark product as described in the operator’s
manual. Such routine maintenance, whether performed by a
dealer or by you, is at your expense.
Warranty Period
90 days
1 Year Prorated
2 years*
* The Engine warranty is covered by the engine manufacturer.
Please refer to the engine manufacturer’s warranty statement
that is included in the literature packet.
General Conditions
The sole liability of Exmark and Exmark Warranty Company
with respect to this warranty shall be repair or replacement of
defective components as set forth herein. Neither Exmark
nor Exmark Warranty Company shall be liable for any
incidental or consequential loss or damage.
This warranty only includes the cost of parts and labor.
Items and Conditions Not Covered
This warranty does not cover the following:
• Pickup and delivery charges to and from any authorized
Exmark Service Dealer.
• Any damage or deterioration due to normal use, wear and
tear, or exposure.
• Cost of regular maintenance service or parts, such as filters,
fuel, lubricants, tune-up parts, and adjustments.
• Any product or part which has been altered or misused or
required replacement or repair due to normal wear,
accidents, or lack of proper maintenance.
• Any repairs necessary due to use of parts, accessories or
supplies, including gasoline, oil or lubricants, incompatible
with the turf equipment or other than as recommended in
the operator's manual or other operational instructions
provided by Exmark.
Such damages include but are not limited to:
• Expenses related to gasoline, oil or lubricants.
• Travel time, overtime, after hours time or other
extraordinary repair charges or charges relating to repairs or
replacements outside of normal business hours at the place
of business of the authorized Exmark Service Dealer.
• Rental of like or similar replacement equipment during the
period of any warranty, repair or replacement work.
• Any telephone or telegram charges or travel charges.
• Loss or damage to person or property other than that
covered by the terms of this warranty.
• Any claims for lost revenue, lost profit or additional cost as
a result of a claim of breach of warranty.
• Attorney's fees.
There are no other express warranties except for engine and
special emission system coverage.
All warranty work must be performed by an authorized
Exmark Service Dealer using Exmark approved replacement
parts.
No Claim of breach of warranty shall be cause for cancellation
or rescission of the contract of sale of any Exmark mower.
All implied warranties of merchantability (that the
product is fit for ordinary use) and fitness for use (that the
product is fit for a particular purpose) are limited to the
duration of the express warranty.
Some states do not allow exclusions of incidental or
consequential damages, or limitations on how long an
implied warranty lasts, so the above exclusions and
limitations may not apply to you.
Instructions for Obtaining Warranty Service
The product must be registered with original proof of purchase
by an Exmark Service Dealer before obtaining any warranty
service.
Contact any Exmark Service Dealer to arrange service at their
dealership. To locate a dealer convenient to you, access our
website at www.exmark.com. U.S. or Canada customers may
also call 402-223-6375.
This warranty gives you specific legal rights, and you may
also have other rights which vary from state to state.
