with the instructions to operate the machine.  
• Clear the area of objects such as rocks, toys, wire,  
etc., which could be picked up and thrown by the  
blade.  
• 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  
1. 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  
The following instructions are from ANSI standard  
B71.1-2003.  
• Operate the machine only in daylight or good  
artificial light.  
• 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.

Safety  
safely enough to protect themselves and others  
from serious injury.  
Children  
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.  
• Always follow the recommendations for wheel  
weights or counterweights.  
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.  
• 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.  
• Do Not mow slopes greater than 15 degrees.  
• Before and while backing or changing direction,  
look behind, down, and side-to-side for small  
children.  
• Watch for ditches, holes, rocks, dips, and rises that  
change the operating angle, as rough terrain could  
overturn the machine.  
• Never carry children, even with the blades off.  
They may fall off and be seriously injured or  
interfere with safe machine operation.  
• 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.  
• 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.  
• Reduce speed and use extreme caution on slopes.  
• Do Not make sudden turns or rapid speed  
changes.  
• 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.  
• 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.  
Towing  
• Use for towing only if equipped with an Exmark  
hitch kit. Do Not attach towed equipment except  
at the hitch point.  
• 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.  
• 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.  
• Always avoid sudden starting or stopping on a  
slope. If tires lose traction, disengage the blades  
and proceed slowly off the slope.  
• Never allow children or others in or on towed  
equipment.  
• Use extreme care with grass collection systems or  
other attachments. These can change the stability  
of the machine and cause loss of control.  
• On slopes, the weight of the towed equipment  
may cause loss of traction and loss of control.  
• Do Not try to stabilize the machine by putting  
your foot on the ground.  
• Travel slowly and allow extra distance to stop.  
• 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.  
Service  
Safe Handling of Gasoline  
• Use a walk behind mower and/or a hand trimmer  
on slopes greater than 15 degrees, near drop-offs,  
ditches, steep banks or water.  
To avoid personal injury or property damage, use  
extra care when handling gasoline and other fuels.  
They are flammable and the vapors are explosive.

heater or furnace.  
• Use only genuine Exmark replacement parts to  
ensure that original standards are maintained.  
• Never fill containers inside a vehicle or on a  
truck or trailer with a plastic liner. Always place  
containers on the ground away from your vehicle  
before filling.  
Exmark Riding Mower Safety  
The following list contains safety information specific  
to Exmark products or other safety information that  
you must know that is not included in the ANSI  
standards.  
• Remove gas-powered equipment from the truck  
or trailer and refuel it on the ground. If this is  
not possible, then refuel such equipment with a  
portable container, rather than from a gasoline  
dispenser nozzle.  
• Engine exhaust contains carbon monoxide, which  
is an odorless, deadly poison that can kill you. Do  
Not run engine indoors or in an enclosed area.  
• Keep the nozzle in contact with the rim of the  
fuel tank or container opening at all times until  
the fueling is complete. Do Not use a nozzle  
lock-open device.  
• Stop the engine, wait for all moving parts to stop,  
engage parking brake, disconnect spark plug  
wire(s) and remove key before performing any  
service, repairs, maintenance or adjustments.  
• If fuel is spilled on clothing, change clothing  
immediately.  
• Keep hands, feet, hair, and loose clothing away  
from attachment discharge area, underside of  
mower and any moving parts while engine is  
running.  
• Never overfill the fuel tank. Replace gas cap and  
tighten securely.  
General Service:  
• Do Not touch equipment or attachment parts  
which may be hot from operation. Allow to cool  
before attempting to maintain, adjust or service.  
• Never run a machine inside a closed area.  
• Keep nuts and bolts tight, especially the blade  
attachment bolts. Keep equipment in good  
condition.  
• Battery acid is poisonous and can cause burns.  
Avoid contact with skin, eyes, and clothing.  
Protect your face, eyes, and clothing when  
working with a battery.  
• Never tamper with safety devices. Check their  
proper operation regularly.  
• Keep the machine free of grass, leaves, or other  
debris build-up. Clean up oil or fuel spillage and  
fuel soaked debris. Allow the machine to cool  
before storing.  
• Battery gases can explode. Keep cigarettes, sparks  
and flames away from battery.  
• Use only Exmark approved attachments.  
Warranty may be voided if used with unapproved  
attachments.  
• Stop and inspect the equipment if you strike an  
object. Repair, if necessary, before restarting.  
• If loading the machine onto a trailer or truck, use  
a single, full-width ramp only. The ramp angle  
should not exceed 15 degrees.  
• Never make any adjustments or repairs with the  
engine running.  
• Grass collection system components are subject  
to wear, damage and deterioration, which could  
expose moving parts or allow objects to be  
thrown. Frequently check components and  
Note: The left and right sides of the machine are  
determined while sitting in the seat in the normal  
operating position

Operation  
Blade Control Switch (Power  
Take-Off)  
Operation  
Located on the control panel.  
Controls  
The blade control switch, represented by a power  
take-off (PTO) symbol, engages and disengages  
power to the mower blades (see Figure 4).  
Note: Become familiar with all of the controls in  
Figure 3 and Figure 4 before you start the engine and  
operate the machine.  
Pull out on the blade control switch to “On” to  
engage the blades.  
Ignition Switch  
Located on control panel.  
Push the blade control switch to “Off ” to disengage  
the blades.  
The ignition switch is used to start and stop the  
engine. The switch has three positions “OFF”,  
“RUN” and “START” ( Figure 4). 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).  
Throttle/Choke Lever  
Located on control panel.  
The throttle is used to control engine speed. Moving  
throttle lever forward will increase engine speed and  
moving throttle lever to the rear will decrease engine  
speed. Moving the throttle forward into the detent is  
full throttle (see Figure 4).  
The choke is used to aid in starting a cold engine.  
Do Not run a warm engine with the choke in the

4. Ignition switch  
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 locks them  
in the neutral position. Always position the motion  
control levers into the neutral position and engage  
the park brake lever 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 (neutral lock position) 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

Operation  
Parking Brake Lever  
DANGER  
Located on left side of the console (Figure 3).  
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.  
The brake lever engages a parking 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.  
To avoid loss of control and possibility of  
rollover:  
Height-of-Cut Foot Lever  
• Do Not mow near drop-offs or near water.  
The height of cut lever allows the operator to lower  
and raise 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. Only adjust the height of cut  
while machine is not moving.  
• Do Not mow slopes greater than 15  
degrees.  
• Reduce speed and use extreme caution  
on slopes.  
• When mowing slopes, gradually work  
from lower to higher areas on the incline.  
• Avoid sudden turns or rapid speed  
changes.  
Hour Meter  
Located on the control panel.  
• Turn up, into an incline when changing  
directions on slopes. Turning down the  
slope reduces traction.  
The hour meter is connected to a pressure switch  
installed in the engine block and it records the number  
of hours that the engine has run ( Figure 4). If the  
ignition switch is left on without engine running, hour  
meter will not run. The hour meter is standard on the  
48 and 52 inch units and optional for the 42 inch unit.  
• Attachments change the handling  
characteristics of the machine. Use extra  
caution when using attachments with the  
machine.  
Note: This switch is not a low oil sensor and will not  
alert the operator if the engine oil is low.  
Operating Instructions  
Think Safety First  
Note: Determine the left and right sides of the  
machine from the normal operating position.  
Please carefully read all of the safety instructions  
and decals in the safety section. Knowing this  
information could help you, your family, pets or  
bystanders avoid injury.

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.  
Recommended Gasoline  
Use UNLEADED Regular Gasoline suitable for  
automotive use (87 pump octane minimum).  
• Always place gasoline containers on the  
ground away from your vehicle before  
filling.  
Important: Never use methanol, gasoline  
containing methanol, or gasohol containing  
more than 10% ethanol because the fuel system  
could be damaged. Do Not mix oil with gasoline.  
• 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.  
DANGER  
In certain conditions gasoline is extremely  
flammable and vapors are explosive.  
• When practical, remove gas-powered  
equipment from the truck or trailer and  
refuel the equipment with its wheels on  
the ground.  
A fire or explosion from gasoline can burn  
you, 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.  
• 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.  
• Never refill the fuel tank or drain the  
machine indoors or inside an enclosed  
trailer.  
• 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.  
• 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  
• Never smoke when handling gasoline,  
and stay away from an open flame or  
where gasoline fumes may be ignited by  
spark.  
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.  
• 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.  
• Avoid prolonged breathing of vapors.  
• Keep face away from nozzle and gas  
tank/container opening.  
• Do Not operate without entire exhaust  
system in place and in proper working  
condition.  
• Keep away from eyes and skin.  
• Never siphon by mouth.

Operation  
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  
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.

and raise off of seat (but do not get off of  
machine) engine must initiate shutdown.  
Understanding the Safety Interlock  
System  
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.  
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.  
Again, run engine at one-third throttle, brake  
engaged, and move left motion control lever in  
- engine must initiate shutdown.  
• The parking brake is engaged.  
The safety interlock system is designed to initiate  
engine shutdown when:  
Repeat again moving the right lever in, then  
moving both levers in - engine must initiate  
shutdown whether operator is on seat or not.  
• The parking brake is disengaged and the operator  
gets off machine.  
Note: If machine does not pass any of these tests,  
Do Not operate. Contact your authorized EXMARK  
SERVICE DEALER.  
• 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.  
Important: It is essential that operator safety  
mechanisms be connected and in proper  
operating condition prior to use for mowing.  
• The parking brake is engaged and motion control  
levers are in.

Operation  
Important: Do Not attempt to turn the unit  
while on the ramp, you may lose control and  
drive off the side.  
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.  
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.  
• Use extreme caution when operating a  
unit on a ramp.  
Operating Tips  
• Use only a single, full width ramp; Do  
Not use individual ramps for each side  
of the unit.  
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.  
• 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.  
Cutting a Lawn for the First Time  
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.  
• Avoid sudden deceleration while backing  
unit down a ramp to avoid tipping  
backward.  
Loading a Unit  
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.  
Cut 1/3 of the Grass Blade  
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.  
Mowing Direction  
Alternate mowing direction to keep the grass standing  
straight. This also helps disperse clippings which  
enhances decomposition and fertilization.  
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.  
Mow at Correct Intervals  
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.  
26

Operation  
Cutting Speed  
To improve cut quality, use a slower ground speed.  
Avoid Cutting Too Low  
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.  
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.

Maintenance  
Drive System Maintenance  
Checking the Tire Pressure  
Service Interval: Every 25 hours/Monthly  
(whichever comes first)  
WARNING  
A worn or damaged blade can break, and a  
piece of the blade could be thrown into the  
operator’s or bystander’s area, resulting in  
serious personal injury or death.  
• Inspect the blade periodically for wear or  
damage.  
Maintain the air pressure in the front and rear tires as  
specified. Uneven tire pressure can cause uneven cut.  
Check the pressure at the valve stem (Figure 31).  
• Replace a worn or damaged blade.  
Check the tires when they are cold to get the most  
accurate pressure reading.  
Before Inspecting or Servicing the  
Blades  
Rear Tires: 13 psi (90 kPa)  
Front Tires (caster wheels):  
• Smooth: 13 psi (90 kPa)  
• Sawtooth: 20 psi (138 kPa)  
Park the machine on a level surface, disengage the  
blade control switch, and move the motion control  
levers outward to the neutral position and engage  
parking brake. Stop the engine, remove the key, and  
disconnect the spark plug wire(s) from the spark  
plug(s).  
Inspecting the Blades  
1. Inspect the cutting edges (Figure 32). If the edges  
are not sharp or have nicks, remove and sharpen  
the blades; refer to Sharpening the Blades.  
Figure 31  
1. Valve stem  
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 32), immediately install  
a new blade.  
Mower Maintenance  
Servicing the Cutting Blades  
Service Interval: Before each use or daily  
Maintain sharp blades throughout the cutting season  
because sharp blades cut 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.  
Figure 32  
1. Cutting edge  
2. Curved area  
3. Wear/slot forming  
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. For convenient sharpening and  
replacement, you may want to keep extra blades on  
hand.  
Checking for Bent Blades  
1. Rotate the blades until the ends face forward and  
backward (Figure 33 and Figure 34). Measure  
from a level surface to the cutting edge, of the  
blades. Note this dimension.

1. Place a wrench on the blade bolt and torque to  
32-42 ft lb (43-57 N-m).  
2. With the wrench still on the blade bolt, hold the  
blade spindle stationary and using a rag or thickly  
padded glove, try to rotate the blade. If the blade  
rotates relative to the spindle guard without  
further tightening the blade bolt, the spring  
disc washer has been flattened or damaged and  
the bolt and washer assembly must be replaced  
(Figure 35). Refer to Removing the Blades and  
Installing the Blades.  
3. Once the blade has been removed, inspect the  
spring disc washer. If the washer appears to be  
damaged (the washer surface has been marred)  
or flattened, the bolt and washer assembly must  
be replaced.

Removing the Blades  
2. Rotate the opposite ends of the blades forward.  
The blades must be replaced if a solid object is hit, if  
the blade is out of balance, or the blade is bent. To  
ensure optimum performance and continued safety  
conformance of the machine, use genuine Exmark  
replacement blades. Replacement blades made by  
other manufacturers may result in an unsafe machine.  
3. Measure from a level surface to the cutting edge  
of the blades at the same position as in step 1.  
The difference between the dimensions obtained  
in steps 1 and 3 must not exceed 1/8 inch (3  
mm). If this dimension exceeds 1/8 inch (3 mm),  
the blade is bent and must be replaced. Refer  
to Removing the Blades and Installing the  
Blades.  
Hold the blade end using a rag or thickly-padded  
glove (or place a wrench on the top sheave nut).  
Remove the blade bolt and washer assembly, washer,  
and blade from the spindle shaft (Figure 35).

Important: The curved part of the blade  
must be pointing upward toward the inside of  
the mower to ensure proper cutting.  
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.  
3. Torque the blade bolt to 32-42 ft-lb (43-57 N-m).

WARNING  
3. Bolt and washer assembly. Apply lubricant to  
threads—torque to 32-42 ft-lb (43-57 N-m).  
Incorrect installation of the blade or  
components used to retain the blade cause  
the blade to come loose and could seriously  
injure or kill you or bystanders.  
Sharpening the Blades  
1. Use a file to sharpen the cutting edge at both ends  
of the blade (Figure 36). Maintain the original  
angle. The blade retains its balance if the same  
amount of material is removed from both cutting  
edges.  
Always install the original Exmark blades,  
washers and blade bolts as shown.  
Mower Belt Maintenance

Check the belts for cracks, frayed edges, burn marks,  
or any other damage. Replace damaged belts.  
1. Sharpen at original angle  
Replacing the Mower Belt  
2. Check the balance of the blade by putting it on a  
blade balancer (Figure 37). 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 37).  
Repeat this procedure until the blade is balanced.  
Squealing when the belt is rotating, blades slipping  
when cutting grass, frayed belt edges, burn marks,  
and cracks are signs of a worn mower belt. Replace  
the mower belt if any of these conditions are evident.  
1. Park the machine on a level surface and disengage  
the blade control switch.  
2. Move the motion control levers outward to the  
neutral position, engage parking brake, stop the  
engine, remove the key, and wait for all moving
