Safety
Safety
• Allow only responsible adults who are familiar
with the instructions to operate the machine.
Safety Alert Symbol
• Clear the area of objects such as rocks, toys, wire,
etc., which could be picked up and thrown by the
blade.
This manual identifies potential hazards and has
safety messages identified by the safety alert symbol
(Figure 2), which signals a hazard that may cause
serious injury or death if you do not follow the
recommended precautions.
• Be sure the area is clear of other people before
mowing. Stop the machine if anyone enters the
area.
• Never carry passengers.
• Do Not mow in reverse unless absolutely
necessary. Always look down and behind before
and while backing up.
Figure 2
Safety Alert Symbol
• Be aware of the mower discharge direction and
Do Not point it at anyone. Avoid discharging
material against a wall or obstruction. Material
may ricochet back toward the operator. Stop the
blades when crossing gravel surfaces.
This manual uses two other words to highlight
information. Important calls attention to special
mechanical information and Note emphasizes
general information worthy of special attention.
• Do Not operate the mower without either the
entire grass collection system or the discharge
deflector in place.
This machine meets or exceeds the safety
specifications of the American National
Standards Institute B71.1-2003 in effect at the
time of production. However, improper use
or maintenance by the operator or owner can
result in injury. To reduce the potential for
injury, comply with these safety instructions
and always pay attention to the safety alert
symbol, which means CAUTION, WARNING,
or DANGER-"personal safety instruction."
Failure to comply with the instruction may result
in personal injury or death.
• Be alert, slow down and use caution when
making turns. Look behind and to the side before
changing directions.
• Never leave a running machine unattended.
Always turn off blades, engage parking brake,
stop engine, and remove key before dismounting.
• Turn off blades when not mowing. Stop the
engine, wait for all parts to come to a complete
stop, engage parking brake, and remove key
before cleaning the machine, removing the grass
or unclogging the deflector.
Safe Operating Practices
• Operate the machine only in daylight or good
artificial light.
The following instructions are from ANSI standard
B71.1-2003.
• Do Not operate the machine while under the
influence of alcohol or drugs.
This product is capable of amputating hands and
feet and throwing objects. Always follow all safety
instructions to avoid serious injury or death.
• Watch for traffic when operating near or crossing
roadways.
• Use extra care when loading or unloading the
machine into a trailer or truck
General Operation
• Always wear eye protection when operating the
mower.
• Read, understand, and follow all instructions in
the operator’s manual and on the machine before
starting.
• Data indicates that operators, age 60 years and
above, are involved in a large percentage of riding
mower-related injuries. These operators should
evaluate their ability to operate the riding mower
• Do Not place hands or feet near rotating parts or
under the machine. Keep clear of the discharge
opening at all times.
5
Safety
Children
safely enough to protect themselves and others
from serious injury.
• Always follow the recommendations for wheel
weights or counterweights.
Tragic accidents can occur if the operator is not
alert to the presence of children. Children are often
attracted to the machine and the mowing activity.
Never assume that children will remain where you
last saw them.
• Keep children out of the mowing area and under
the watchful care of another responsible adult,
not the operator.
• Be alert and turn the machine off if children enter
the area.
• Before and while backing or changing direction,
look behind, down, and side-to-side for small
children.
• Never carry children, even with the blades off.
They may fall off and be seriously injured or
interfere with safe machine operation.
• Children who have been given rides in the past
may suddenly appear in the mowing area for
another ride and be run over or backed over by
the mower.
• Never allow children to operate the machine.
• Use extra care when approaching blind corners,
shrubs, trees, the end of a fence or other objects
that may obscure vision.
Slope Operation
Slopes are a major factor related to loss of control
and tip-over accidents, which can result in severe
injury or death. Operation on all slopes requires extra
caution. If you cannot back up the slope or if you feel
uneasy on it, Do Not mow it.
• Do Not mow slopes greater than 15 degrees.
• Watch for ditches, holes, rocks, dips, and rises that
change the operating angle, as rough terrain could
overturn the machine.
• Choose a low ground speed so you will not have
to stop while operating on a slope.
• Do Not mow slopes when grass is wet. Slippery
conditions reduce traction and could cause sliding
and loss of control.
• Reduce speed and use extreme caution on slopes.
• Do Not make sudden turns or rapid speed
changes.
• Remove or mark obstacles such as rocks, tree
limbs, etc. from the mowing area. Tall grass can
hide obstacles.
• Avoid sudden starts when mowing uphill because
the mower may tip backwards.
• Be aware that operating on wet grass, across steep
slopes or downhill may cause the mower to lose
traction. Loss of traction to the drive wheels may
result in sliding and a loss of braking and steering.
• Always avoid sudden starting or stopping on a
slope. If tires lose traction, disengage the blades
and proceed slowly off the slope.
• Use extreme care with grass collection systems or
other attachments. These can change the stability
of the machine and cause loss of control.
• Do Not try to stabilize the machine by putting
your foot on the ground.
• Do Not mow near drop-offs, ditches, steep banks
or water. Wheels dropping over edges can cause
rollovers, which may result in serious injury, death
or drowning.
• Use a walk behind mower and/or a hand trimmer
on slopes greater than 15 degrees, near drop-offs,
ditches, steep banks or water.
Towing
• Use for towing only if equipped with an Exmark
hitch kit. Do Not attach towed equipment except
at the hitch point.
• Follow Exmark’s recommendation for weight
limits for towed equipment and towing on slopes.
This information can be found in the hitch kit
instruction sheet and on the decal.
• Never allow children or others in or on towed
equipment.
• On slopes, the weight of the towed equipment
may cause loss of traction and loss of control.
• Travel slowly and allow extra distance to stop.
Service
Safe Handling of Gasoline
To avoid personal injury or property damage, use
extra care when handling gasoline and other fuels.
They are flammable and the vapors are explosive.

The motion control levers are speed sensitive controls
of independent wheel motors. Moving a lever
forward or backward turns the wheel on the same side
forward or in reverse; wheel speed is proportional to
the amount the lever is moved. Moving the control
levers outward from the center position engages the
parking brake on the drive wheels. Always position
the motion control levers into the parking brake
position when you stop the machine or leave it
unattended. The unit must be tied down and brake
engaged when transporting.
Note: Brake must be engaged (motion control levers
out) and PTO switch “OFF” to start engine. (It is
not necessary for the operator to be in the seat to
start the engine.)
Turning the key to the Off position will stop the
engine; however, always remove the key when leaving
the machine to prevent someone from accidentally
starting the engine.
Deck Height Adjustment Lever
Located below the RH motion control lever
(Figure 3).
17
Operation
Pull the lever inward and rearward to raise the cutting
deck. Allow the handle to move forward to lower the
cutting deck. Move the deck height adjustment lever
outward at the desired height-of-cut. Only adjust the
height of cut while the machine is not moving.
DANGER
Mowing on wet grass or steep slopes can cause
sliding and loss of control. Wheels dropping
over edges can cause rollovers, which may result
in serious injury, death or drowning. A loss of
traction is a loss of steering control.
Height-of-Cut Foot Lever
To avoid loss of control and possibility of rollover:
The height-of-cut foot lever allows the operator to
use their leg to assist in lowering and raising the deck
from the seated position (Figure 3). When the lever
is moved forward, away from the operator the deck
is raised from the ground and when moved back,
towards the operator it is lowered toward the ground.
• Do Not mow near drop-offs or near water.
• Do Not mow slopes greater than 15 degrees.
• Reduce speed and use extreme caution on
slopes.
Fuel Window
• When mowing slopes, gradually work from
lower to higher areas on the incline.
Located on the left side of the machine (see Figure 5).
• Avoid sudden turns or rapid speed changes.
The fuel window can be used to verify the presence
of fuel in the tank.
• Turn up, into an incline when changing
directions on slopes. Turning down the slope
reduces traction.
• Attachments change the handling
characteristics of the machine. Use extra
caution when using attachments with the
machine.

Operation
Recommended Gasoline
DANGER
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.
• 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.
Fill fuel tank on level ground. See Fuel
Recommendations in the Specifications section for
additional gasoline information.
Do Not add oil to gasoline.
Do Not overfill fuel tank. Fill the fuel tank to the
bottom of the filler neck. The empty space in the
tank allows gasoline to expand. Overfilling may result
in fuel leakage or damage to the engine or emission
system.
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.
• Fill the fuel tank outdoors on level ground, in
an open area, when the engine is cold. Wipe
up any gasoline that spills.
• Never refill the fuel tank or drain the machine
indoors or inside an enclosed trailer.
• Do Not fill the fuel tank completely full. Add
gasoline to the fuel tank until the body of the
tank is full but fuel does not fill the neck of
the tank. This empty space in the tank allows
gasoline to expand.
WARNING
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.
• 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.
• Never smoke when handling gasoline, and
stay away from an open flame or where
gasoline fumes may be ignited by spark.
• Store gasoline in an approved container and
keep it out of the reach of children. Never
buy more than a 30-day supply of gasoline.
• Do Not operate without entire exhaust system
in place and in proper working condition.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to
provide the following benefits:
• Keeps gasoline fresh during storage of 30 days or
less. For longer storage it is recommended that
the fuel tank be drained.
• Cleans the engine while it runs.
• Eliminates gum-like varnish buildup in the fuel
system, which causes hard starting Add the

Operation
correct amount of gas stabilizer/conditioner to
the gas.
Note: A fuel stabilizer/conditioner is most effective
when mixed with fresh gasoline. To minimize the
chance of varnish deposits in the fuel system, use fuel
stabilizer at all times.
Filling the Fuel Tank
Make sure the engine is shut off and the motion
controls are in the park position. Tank maximum
capacity is 2.9 gallons.
Important: Do Not overfill fuel tank. Fill the
fuel tank to the bottom of the filler neck. The
empty space in the tank allows the fuel to expand.
Overfilling may result in fuel leakage or damage
to the engine or emission system.

3. Add unleaded regular gasoline until the fuel
reaches the base of the filler neck and does not
fill the neck of the tank (Figure 7). This space
at the base of the filler neck allows gasoline to
expand. Do Not fill the fuel tank completely full.
Overfilling may result in fuel leakage or damage
to the engine or emissions system.
Checking the Engine Oil

The Safety Interlock System
do not get off of machine) engine must initiate
shutdown.
CAUTION
Run engine at one-third throttle, with brake
disengaged, move levers in and raise off seat (but
do not get off of machine) engine must initiate
shutdown.
If the safety interlock switches are disconnected
or damaged the machine could operate
unexpectedly causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches
before operating the machine.
Note: If machine does not pass any of these tests,
Do Not operate. Contact your authorized EXMARK
SERVICE DEALER.
Important: It is essential that operator safety
mechanisms be connected and in proper
operating condition prior to use for mowing.
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
• The blades are disengaged.
• The motion control levers are in the neutral
position.
• The parking brake is engaged.
Driving Forward or Backward
The throttle control regulates the engine speed as
measured in rpm (revolutions per minute). Place
the throttle control in the Fast position for best
performance. Always operate in the Fast (full throttle)
position.
The safety interlock system is designed to initiate
engine shutdown when:
• The parking brake is disengaged and the operator
gets off machine.
• The PTO is engaged and the operator gets off
machine.
• The parking brake is disengaged and levers are in
and the operator gets off machine.
CAUTION
Machine can spin very rapidly by positioning one
lever too much ahead of the other. Operator may
lose control of the machine, which may cause
damage to the machine or injury.
• Use caution when making turns.
• Slow the machine down before making sharp
turns.
Testing the Safety Interlock System
Test the safety interlock system before you use the
machine each time
1. Check starting circuit. Starter should crank with
the PTO disengaged and motion control levers
moved out in the parking brake position. The
operator does not need to be in the seat to start
the engine.

2. To go forward, slowly push the motion control
levers forward (Figure 10).
Try to start with operator in seat, PTO
disengaged and motion control levers in the
parking brake position - starter must not crank.
Try to start with operator in seat, PTO
disengaged, and the left motion control lever
in, starter must not crank, repeat again with the
right lever in, then with both levers in - starter
must not crank.
2. Check kill circuits. Run engine at one-third

Operation
Operating Tips
WARNING
Loading a unit on a trailer or truck increases
the possibility of backward tip-over. Backward
tip-over could cause serious injury or death.
• Use extreme caution when operating a unit
on a ramp.
• Use only a single, full width ramp; Do Not
use individual ramps for each side of the unit.
• If individual ramps must be used, use enough
ramps to create an unbroken ramp surface
wider than the unit.
• Do Not exceed a 15° angle between ramp and
ground or between ramp and trailer or truck.
• Avoid sudden acceleration while driving unit
up a ramp to avoid tipping backward.
• Avoid sudden deceleration while backing unit
down a ramp to avoid tipping backward.
Cut grass slightly longer than normal to ensure that
the cutting height of the mower does not scalp any
uneven ground. However, the cutting height used in
the past is generally the best one to use. When cutting
grass longer than six inches tall, you may want to cut
the lawn twice to ensure an acceptable quality of cut.
Loading a Unit
Cut 1/3 of the Grass Blade
Use extreme caution when loading units on trailers or
trucks. One full width ramp that is wide enough to
extend beyond the rear tires is recommended instead
of individual ramps for each side of the unit. The
lower rear section of the tractor frame extends back
between the rear wheels and serves as a stop for
tipping backward. Having a full width ramp provides
a surface for the frame members to contact if the
unit starts to tip backward. If it is not possible to use
one full width ramp, use enough individual ramps to
simulate a full width continuous ramp.
It is best to cut only about 1/3 of the grass blade.
Cutting more than that is not recommended unless
grass is sparse, or it is late fall when grass grows more
slowly.
Fast Throttle Setting
For best mowing and maximum air circulation,
operate the engine at the Fast position. Air is required
to thoroughly cut grass clippings, so Do Not set the
height-of-cut so low as to totally surround the mower
by uncut grass. Always try to have one side of the
mower free from uncut grass, which allows air to be
drawn into the mower.
Cutting a Lawn for the First Time
Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which
enhances decomposition and fertilization.
Mow at Correct Intervals
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
backward. 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.
Normally, mow every four days. But remember,
grass grows at different rates at different times.
So to maintain the same cutting height, which is a
good practice, mow more often in early spring. As
the grass growth rate slows in mid summer, mow
less frequently. If you cannot mow for an extended
period, first mow at a high cutting height; then mow
again two days later at a lower height setting.
Cutting Speed
Important: Do Not attempt to turn the unit
while on the ramp, you may lose control and
drive off the side.
To improve cut quality, use a slower ground speed.
Avoid sudden acceleration when driving up a ramp
and sudden deceleration when backing down a ramp.
Both maneuvers can cause the unit to tip backward.
If the cutting width of the mower is wider than the
mower you previously used, raise the cutting height
to ensure that uneven turf is not cut too short.
Avoid Cutting Too Low
28
Operation
Long Grass
If the grass is ever allowed to grow slightly longer
than normal, or if it contains a high degree of
moisture, raise the cutting height higher than usual
and cut the grass at this setting. Then cut the grass
again using the lower, normal setting.
When Stopping
If the machine’s forward motion must be stopped
while mowing, a clump of grass clippings may drop
onto your lawn. To avoid this, move onto a previously
cut area with the blades engaged.
Keep the Underside of the Mower
Clean
Clean clippings and dirt from the underside of the
mower after each use. If grass and dirt build up inside
the mower, cutting quality will eventually become
unsatisfactory.
Blade Maintenance
Maintain a sharp blade throughout the cutting season
because a sharp blade cuts cleanly without tearing or
shredding the grass blades. Tearing and shredding
turns grass brown at the edges, which slows growth
and increases the chance of disease. Check the
cutter blades daily for sharpness, and for any wear or
damage. File down any nicks and sharpen the blades
as necessary. If a blade is damaged or worn, replace
it immediately with a genuine Exmark replacement
blade. Only Exmark blades are to be used with this
unit. No other blades are approved.

warm. The oil will flow more freely and carry away
more impurities. Make sure the engine is level when
filling, checking, or changing the oil.
2. Make sure the engine is stopped, level, and is cool
so the oil has had time to drain into the sump.
3. To keep dirt, grass clippings, etc., out of
the engine, clean the area around the oil fill
cap/dipstick before removing it.
1. Start the engine and let it run until warm. This
warms the oil so it drains better.
4. Remove the oil fill cap/dipstick; wipe oil off.
Reinsert the dipstick push into place, but Do Not
screw it in (Figure 24).
2. Disengage the blade control switch and move the
motion controls outward to the parking brake
position.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating

until it reaches the FULL COLD line on the
expansion reservoir.
2. Repeat step 1 until all the air is completely purged
from the system.
Inspecting the Blades
1. Inspect the cutting edges (Figure 39). If the edges
are not sharp or have nicks, remove and sharpen
the blades; refer to Sharpening the Blades.
When the transaxle operates at normal noise
levels and moves smoothly forward and reverse at
normal speeds, then the transaxle is considered
purged.
2. Inspect the blades, especially the curved area. If
you notice any damage, wear, or a slot forming in
this area (item 3 in Figure 39), immediately install
a new blade.
3. Check the oil level in the expansion reservoir one

Leveling the Mower Deck
Check to ensure the mower deck is level any time
you install the mower or when you see an uneven cut
on your lawn.
Figure 45
The mower deck must be checked for bent blades
prior to leveling; any bent blades must be removed
and replaced. Refer to the Checking for Bent
Blades procedure before continuing.
1. Sharpen at original angle
2. Check the balance of the blade by putting it on a
blade balancer (Figure 46). If the blade stays in a
horizontal position, the blade is balanced and can
be used. If the blade is not balanced, file some
metal off the end of the sail area only (Figure 46).
Repeat this procedure until the blade is balanced.
The mower deck must be leveled side-to-side first
then the front to rear slope can be adjusted.
Requirements:
• The machine must be on a level surface.
• All four tire must be properly inflated. Refer to
Checking the Tire Pressure in the Drive System
Maintenance section.

and wait for all moving parts to stop before
leaving the operating position.
Installing the Blades
1. Install the blade onto the spindle shaft (Figure 44).
3. Set the height-of-cut lever to middle position.
Important: The curved part of the blade
must be pointing upward toward the inside of
the mower to ensure proper cutting.
4. Carefully rotate the blades so that they are all side
to side (Figure 47 and Figure 48).
2. Hold the blade end using a rag or thickly-padded
glove (or place a wrench on the top sheave nut).
Apply lubricant to the threads of the blade bolt
as needed to prevent seizing. Copper based
anti-seize is preferable. Grease is an acceptable
substitute. Install the washer and blade bolt and
washer assembly.

particular purpose) are limited to the duration of the express
warranty.
