WARNING
FAILURE TO FOLLOW SAFE OPERATING PRACTICES MAY RESULT
IN SERIOUS INJURY OR DEATH.
• Read this manual completely as well as other manuals that came with your mower.
• DO NOT operate on steep slopes. To check a slope, attempt to back up it (with the
cutter deck down). If the machine can back up the slope without the wheels slipping,
reduce speed and use extreme caution.
• Under no circumstances should the machine be operated on slopes greater than 15
degrees. ALWAYS FOLLOW OSHA APPROVED OPERATION.
• Stay two cut widths away from slopes, drop offs, ditches and retaining walls.
• DO NOT mow on wet grass. Wet grass reduces traction and steering control.
• Keep all shields in place, especially the grass discharge chute.
• Before performing any maintenance or service, stop the machine and remove the
spark plug wire and ignition key.
• If a mechanism becomes clogged, stop the engine before cleaning.
• Keep hands, feet and clothing away from power-driven parts.
• Keep others off the mower (only one person at a time).
REMEMBER - YOUR MOWER IS ONLY AS SAFE AS THE OPERATOR!
Hazard control and accident prevention are dependent upon the awareness,
concern, prudence, and proper training of the personnel involved in the
operation, transport, maintenance, and storage of the equipment.

DO NOT use your hand to dislodge the clogged
discharge chute. Use a stick or other device to
remove clogged material after the engine has
stopped running and the blades have stopped
turning.
WARNING
DO NOT operate on steep slopes. To check a slope,
attempt to back up it (with the cutter deck down).
If the machine can back up the slope without the
wheels slipping, reduce speed and use extreme
caution. Under no circumstances should the
machine be operated on slopes greater than 15
degrees. See Figure 2-2, Page 7 to determine
approximate slope of area to be mowed. ALWAYS
FOLLOW OSHA APPROVED OPERATION.
9. Be alert for holes, rocks, roots and other hidden
hazards in the terrain. Keep away from any drop-offs.
Beware of overhead obstructions (low limbs, etc.)
and underground obstacles (sprinklers, pipes, tree
roots, etc.). Cautiously enter a new area. Be alert for
hidden hazards.
10. Disengage power to cutter deck before backing up.
Do not mow in reverse unless absolutely necessary
and then only after observation of the entire area
behind the mower. If you must mow in reverse,
maintain a constant lookout to the rear of the
machine and mow slowly.
2. Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tipping or loss
of control. Be especially cautious when changing
directions on slopes.
3. Stay two cut widths away from slopes, drop offs,
ditches and retaining walls.
11. DO NOT turn sharply. Use care when backing up.
12. Disengage power to cutter deck before crossing
roads, walks or gravel drives.
4. To prevent tipping or loss of control, start and stop
smoothly, avoid unnecessary turns and travel at
reduced speed. Use caution when operating the
mower on an incline with the optional grass catcher
installed.
13. Mow only in daylight or good artificial light.
14. NEVER raise the deck with the blades engaged.
5. Immediately apply the parking brake if you lose
steering control while operating. Inspect the machine
and correct the problem before continuing to operate.
15. Take all possible precautions when leaving the
machine unattended, such as disengaging the
mower, lowering the attachments, setting the parking

6. When using any attachment, never direct the
discharge of material toward bystanders or allow
anyone near the machine while in operation.
16. Disengage power to the attachments when
transporting or when not in use.
7. Before attempting to start the engine, with the
operator in the seat, disengage power to the cutter
deck, place the steering control levers in the neutral
position and engage the parking brake.
17. The machine and attachments should be stopped
and inspected for damage after striking a foreign
object, and damage should be repaired before
restarting and operating the machine.
8. If the mower discharge ever plugs, shut off the
engine, remove the ignition key, and wait for all
movement to stop before removing the obstruction.
Caution
Do not touch the engine or the muffler while the
engine is running or immediately after stopping.
These areas may be hot enough to cause a
burn.

Section 2
R
DANGER
Any or all parts of the Roll-Over Protection System MUST
NOT be removed. Failure to adhere to this guideline could
result in injury or death.
DO NOT run the engine inside a building or
a confined area without proper ventilation.
Exhaust fumes are hazardous and contain
carbon monoxide which can cause brain injury
and death.
The potential exposure of the seat belt to severe
environmental conditions make it crucial to inspect the seat
belt system regularly.
It is recommended that the seat belt be inspected on a
daily basis for signs of damage. Any seat belt system that
shows cuts, fraying, extreme or unusual wear, significant
discoloration due to UV exposure, dirt or stiffness, abrasion
to the seat belt webbing, or damage to the buckle, latch
plate, hardware or any other obvious problem should be
replaced immediately.
18. Keep hands and feet away from cutter blades and
moving parts. Contact can injure.
19. Transport the mower using a heavy duty trailer
or truck. Insure the trailer or truck has all of the
necessary lighting and markings as required by
laws, codes, and ordinances. Secure a trailer with a
safety chain.
WARNING
20. Be cautious when loading and unloading onto
trailers or trucks. Use only a full width ramp. Ramp
angle should be no more than 15 degrees. Back up
the ramp and drive down forward.
Failure to properly inspect and maintain the seat
belt can cause serious injury or loss of life.
21. When transporting the mower, make sure the park
brake is engaged, the steering control levers are in
the neutral position, the engine is off with the key
removed, and the wheels have been blocked.
1. Check the full length of the seat belt webbing for
cuts, wear, fraying, dirt and stiffness. See Figure 2-1.
2. Check the seat belt webbing in areas exposed to
ultra violet rays from the sun or extreme dust or
dirt. If the original color of the webbing in these
areas is extremely faded and/or is packed with dirt,
the physical strength of this webbing may have
deteriorated. If this condition exists, replace the seat
belt system.
22. Tie the mower down securely using straps, chains,
cable, or ropes. Both front and rear straps must be
directed down and outward from machine.
23. Use care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.
24. NEVER leave the machine running unattended.
3. Check the buckle and latch for proper operation
and determine if the latch plate is excessively worn,
deformed, or if the buckle is damaged or cracked.
See Figure 2-1.
2.5 Roll-over protection system
WARNING
INSPECT BUCkLE
& LATCH
The seat belt must be securely fastened during
operation. Failure to do so could cause serious
injury or loss of life.
INSPECT WEBBING
Figure 2-1. Seat Belt Inspection
This mower has been designed for good traction and
stability under normal mowing conditions. However, caution
must be used when traveling on slopes, especially when the
grass is wet. Do not mow on wet grass. Wet grass reduces

4.4 STARTING THE ENGINE
Practice operating the mower until you are
comfortable with the controls before proceeding
to mow.
CAUTION
Forward Travel
To travel forward with the mower, disengage the parking
brake, pull levers inward out of the neutral lock position
and slowly push the steering control levers forward an
equal distance. The further the steering control levers are
pushed forward the greater the forward speed will be. To
increase the speed, push the steering control levers further
forward and to decrease the speed, pull the steering control
levers back.
DO NOT USE STARTING FLUIDS. Use of starting
fluids in the air intake system may be potentially
explosive or cause a “runaway” engine condition
that could result in engine damage and/or
personal injury.
1. Be sure the fuel shutoff valve, located behind the
operator's seat, is completely open.
To stop the forward travel, pull the steering control levers
back to the neutral position.
2. Sit in the operator’s seat, fasten seat belt and place
the steering control levers in the neutral position.
To steer the mower left while traveling forward, pull the left
steering lever back. The further the lever is pulled back, the
quicker the mower will turn left.
3. Engage the parking brake.
4. Place the PTO switch in the disengaged position.
5. If the engine is cold, choke the engine as needed.
To steer the mower right while traveling forward, pull the
right steering control lever back. The further the lever is
pulled back, the quicker the mower will turn right.
6. Move the engine throttle control to about half engine
speed.
7. Turn the ignition key to the START position and
release the key as soon as the engine starts. Do
not hold the key in the START position for more
than 15 seconds at a time. Allow at least 60
seconds between each cranking attempt to prevent
overheating of the starter motor. Prolonged cranking
can damage the starter motor and shorten battery
life.
- NOTE Smooth operation of the steering levers will
produce smooth mower operation. While learning
the operation of the steering controls, keep the
travel speed low.
- IMPORTANT -
8. Allow engine to warm before operating the mower.
Do not travel forward over a curb. The mower will
hang up on the curb. Raise the deck and travel
backwards over the curb at a 45 degree angle.
(See Figure 4-1 item 12 for cutter deck raising
description.)
4.5 GROUND TRAVEL AND STEERING
- IMPORTANT If you are not familiar with the operation of a
machine with lever steering and/or hydrostatic
transmissions, the steering and ground speed
operations should be learned and practiced in
an open area, away from buildings, fences, or
obstructions.
Learn the operation on flat ground before operating
on slopes.

4.6 ENGAGING THE DECK DRIVE (CUTTER
BLADES)
Reverse Travel
Caution
1. Set the throttle at about 3/4 speed. Do not attempt to
engage the deck drive at high speed as this shortens
the electric clutch life — use only moderate engine
speed when engaging the deck drive.
Disengage power to the mower before backing
up. Do not mow in reverse unless absolutely
necessary and then only after observation of the
entire area behind the mower.
2. Engage the deck drive by pulling out on the yellow
switch, located on the instrument panel, to the
engage position. See Figure 4-3.
Caution
Before backing up, observe the rear for persons
and obstructions. Clear the area before backing
up. Possible injury or property damage could
occur.
PULL UP TO ENGAGE
PUSH DOWN TO DISENGAGE
To travel in reverse, pull levers inward out of the neutral
lock position and pull both handles back. Keep the travel
speed low while traveling in reverse.
Figure 4-3. Cutter Engage Switch
- NOTE -
- NOTE -
The mower may not travel straight in reverse.
Slight adjustments may need to be made using
the steering controls.
A squealing noise may be heard when engaging
or disengaging the deck drive. It is caused by the
electric clutch plates meshing as the mower comes
up to speed. This is normal.
390S0138
To steer left while traveling in reverse, allow the left steering
control lever to move forward. The further the control is
allowed to move forward, the quicker the mower will turn
left.
3. To disengage the deck drive, push the switch in to
the disengage position.
4. Always operate the engine at full throttle to properly
maintain cutting speed. If the engine starts to lug
down, reduce the forward speed and allow the
engine to operate at maximum RPM.
To steer right while traveling in reverse, allow the right
steering control lever to move forward. The further the
control is allowed to move forward, the quicker the mower
will turn right.
To stop the reverse travel, allow the steering control levers
to return to the neutral position. If the mower is to be parked,
place the handles in the neutral lock position and engage
the parking brake.

Section 4
R
4.7 HILLSIDE OPERATION
4.8 PARKING THE MOWER
1. Park the machine on a flat, level surface only. Do not
park the machine on an incline.
WARNING
2. Place the steering control levers in the neutral
position.
DO NOT operate on steep slopes. To check a slope,
attempt to back up it (with the cutter deck down).
If the machine can back up the slope without the
wheels slipping, reduce speed and use extreme
caution. Under no circumstances should the
machine be operated on slopes greater than 15
degrees. See Figure 2-2, Page 7 to help determine
approximate slope of area to be mowed. ALWAYS
FOLLOW OSHA APPROVED OPERATION.
3. Disengage the cutter blades.
4. Slow the engine to idle speed.
5. Engage the parking brake.
6. Turn the ignition key to the OFF position and remove
the key.
4.9 AFTER OPERATION
1. Wash the entire mower after each use. Do not
use high pressure spray or direct the spray onto
electrical components.
1. This mower has been designed for good traction
and stability under normal mowing conditions.
However, caution must be used when traveling on
slopes, especially when the grass is wet. Wet grass
reduces traction and steering control. The Roll-Over
Protection System is standard equipment for this
machine. See Section 2.5, page 6 of this manual for
further details.
- IMPORTANT Do not wash a hot or running engine. Cold water
will damage the engine. Use compressed air to
clean the engine if it is hot.
2. Stay two cut widths away from slopes, drop offs,
ditches and retaining walls.
2. Keep the entire mower clean to inhibit serious heat
damage to the engine or hydraulic oil circuit.
3. Some areas may need to be mowed with a walkbehind mower or string trimmer.
3. Check the drive belts for proper alignment and any
signs of wear. Correct and adjust if necessary.
4. To prevent tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel
at reduced speed. If tires lose traction, disengage
blades and proceed slowly off the slope.
Danger
5. Avoid sudden starts when mowing uphill. Sudden
starts may cause the machine to tip backwards.
To avoid injury from burns, allow the mower
to cool before removing the fuel tank cap and
refueling.
6. Loss of traction may occur when traveling down hill.
Weight transfers to the front of the machine and
may cause the drive wheels to slip causing loss of
braking or steering.
4. After the mower has cooled down, fill the fuel tank
with fresh, clean fuel at the end of every day of
operation. See Engine Owner's Manual for proper
octane requirements.
7. Keep tires properly inflated.
8. Use caution when operating the mower on an incline
with the optional grass catcher installed.
5. Check the tire pressure. Adjust pressure if
necessary.

Section 4
R
4.10 REMOVING CLOGGED MATERIAL
ROTATING BLADES
2. The discharge chute must not be removed and
must be kept in the lowest position to deflect grass
clippings and thrown objects downward. Direct the
side discharge away from sidewalks or streets to
minimize cleanup of clippings. When mowing close
to obstacles, direct the discharge away from the
obstacles to reduce the chance of property damage
by thrown objects.
NEVER PUT YOUR HANDS INTO THE DISCHARGE
CHUTE FOR ANY REASON!
3. Cut grass when it is dry and not too tall. Do not cut
grass too short (cut off 1/3 or less of existing grass
for best appearance). Mow frequently.
Danger
4. Keep mower and discharge chute clean.
Shut off the engine and remove the key and
only then use a stick or similar object to remove
material if clogging has occurred.
5. When mowing wet or tall grass, mow the grass twice.
Raise the mower to the highest setting for the first
pass and then make a second pass to the desired
height.
1. If the discharge chute becomes clogged, shut off
the engine and remove the ignition key. Using a stick
or similar item, dislodge the clogged material. Then
resume normal mowing.
6. Use a slow travel speed for trimming purposes.
7. Operate the engine at full throttle for best cutting.
Mowing with a lower RPM causes the mower to tear
the grass. The engine is designed to be operated at
full speed.
4.11 MOVING MOWER WITH ENGINE
STOPPED
8. Use the alternate stripe pattern for best lawn
appearance. Vary the direction of the stripe each
time the grass is mowed to avoid wear patterns in
the grass.
To “free-wheel” or move the mower around without the
engine running, place the dump valve levers in the FREEWHEEL position. See Figure 4-2, page 13. Disengage the
parking brake and move the mower by hand. When the
machine is in the desired position, engage the parking
brake and place the dump valve levers in the DRIVE
position. The dump valve levers must be returned to the
DRIVE position to drive the mower.
4.13 ADJUSTING CUTTING HEIGHT
The mower deck can be adjusted from a height of 1 inch
to 4-1/2 inches at 1/4-inch intervals. To adjust the cutting
height:
4.12 RECOMMENDATIONS FOR MOWING
WARNING
1. Do not mow with dull blades. A dull blade will tear
grass, resulting in poor lawn appearance and
reduced mowing power.
DO NOT adjust the cutting height with the mower
blades rotating. Disengage the power to the cutter
blades and then adjust cutting height.
WARNING
1. Disengage the power to the cutter blades.
DO NOT operate without Discharge Chute,
Mulching Kit, or entire Grass Catcher properly
installed.
2. Push the cutting height adjustment foot pedal all
the way forward using your right foot until it locks in

6.6 CUTTER DECK ADJUSTMENTS
Cutter Deck Pitch
Cutter deck level, pitch and height are set at the factory.
However, if these adjustments should ever need to be
made, the following procedures will aid in obtaining the
proper cutter deck adjustment.
The pitch of the cutter deck should be equal between
the front and rear of the cutter deck for proper cutting
performance. To check for proper deck pitch, be sure
that the mower is on a flat, level surface and the tires are
properly inflated.
- NOTE -
Check the distance from the top of the cutter deck to the
floor at the rear RH side of the cutter deck directly behind
the cutter deck hanging chains. Next check the distance
from the top of the cutter deck to the floor at the front RH
side of the cutter deck directly in front of the cutter deck
hanging chains. The measurement at the front of the cutter
deck should be the same as the rear of the deck. Make
these measurements at the LH side of the cutter deck also.
If the measurement at the front of the deck is not the same,
the cutter deck pitch must be adjusted as follows:
Before proceeding with the cutter deck adjustments,
be sure that all tires are properly inflated.
Cutter Deck Level
The cutter deck should be level from side-to-side for
proper cutting performance. To check for level, be sure
that the mower is on a flat, level surface, the tires are
properly inflated and the cutter deck is set at the most
common cutting height that you will use. On the RH side
of the machine, check the distance from the top of the
cutter deck to the floor. Next check the distance from the
top of the cutter deck to the floor on the LH side of the
machine. Both measurements should be the same. If the
two measurements are different, the cutter deck level must
be adjusted as follows:
1. Loosen the elastic stop nuts securing the deck level
links on the front of the cutter deck on both sides.

6.7 electric clutch adjustment
ADJUSTMENT NUTS
The electric clutch serves two functions in the operation of
the mower. In addition to starting and stopping the power
flow to the cutter blades, the clutch also acts as a brake to
assist in stopping blade rotation when the PTO is switched
off or the operator presence circuit is interrupted.
When the clutch is disengaged, the air gap between the
armature and rotor must be adjusted to fifteen thousandths
of an inch, 0.015, for proper operation. The airgap
adjustment is made at three bolts on the clutch. There are
three inspection windows, one next to each adjusting bolt.
See Figure 6-8.
INSPECTION WINDOW (x3)
ADJUSTMENT NUTS
Figure 6-10. Clutch Air Gap Adjustment
Figure 6-8. Clutch Air Gap Adjustment
This adjustment should be done every 500 hours of
operation or annually, whichever comes first. In cases
where the machine is heavily used, airgap settings should
be checked more often.
1. Locate the inspection windows on the clutch.
2. Place a 0.015 feeler gauge in the slot between the
rotor and the armature. See Figure 6-9.
If the air gap is too narrow, the clutch armature may drag
when disengaged, resulting in premature failure.
INSERT 0.015 FEELER GAUGE HERE
If the air gap is too wide, the clutch may be slow to engage
as the magnet must pull the armature in from a greater
distance.
Figure 6-9. Clutch Air Gap Adjustment
3. Tighten or loosen the adjusting bolt as needed to
acheive the 0.015 inch airgap. See Figure 6-10.
Perform this operation at all three inspection
windows.

- IMPORTANT -
7.2 Hydraulic System
The hydraulic system oil should be changed if you
notice the presence of water or a rancid odor to
the hydraulic oil.
A. Checking Hydraulic Oil Level
The hydraulic oil level should be checked after the first 10
hours of operation. Thereafter, check the oil after every
200 hours of machine operation or monthly, whichever
occurs first.
1. Park the mower on a level surface and stop the
engine.
2. Remove the three 1/4" filter guard screws and filter
guard from both axles. See Figure 7-2. Clean any
loose debris around the perimeter of the filter.
- IMPORTANT If the oil level is consistently low, check for leaks
and correct immediately.
1. Wipe dirt and contaminants from around the
reservoir cap. Remove the cap from the hydraulic oil
reservoir.
2. When the machine is "cold" (before operation),
visually check the level of the hydraulic system oil.
Hydraulic system oil level should be in the middle of
the indicator window located on the left side of the
machine. See Figure 7-1. DO NOT overfill; (overfilling
the oil reservoir may cause oil seepage).
3. Clean the fill cap and install it onto the reservoir.

3. Place a suitable container under the hydraulic oil
filters. Remove the cover from the left side tank to
gain access to the hydraulic expansion reservoir.
Remove the fill cap from the reservoir.
4. Remove the hydraulic filters from both axles and
allow the fluid to drain into the container. Properly
discard the oil when the system has drained
completely. See Figure 7-2.
Figure 7-1. Hydraulic System Oil Level
B. Changing Hydraulic Oil
5. Once the hydraulic system has drained, install new
hydraulic oil filters to both axles by hand, turn 3/4
to one complete turn after filter gasket contacts the
filter base.
The hydraulic system oil should be changed after the first
120 hours of machine operation and every 400 hours or
annually thereafter, whichever occurs first. The oil should
also be changed if the color of the fluid has become black
or milky. A black color and/or a rancid odor usually indicates
possible overheating of the oil, and a milky color usually
indicates water in the hydraulic oil.
6. Reinstall the filter guards and torque the screws to
65 in/lbs.

control levers to full forward and reverse 5 to 6 times.
-NOTE-
14. Engage the parking brake. Move the dump valve
comtrol levers to the "drive" position. See Figure 7-4.
The left side axle will fill with oil first using
approximately 4 quarts of oil. Reinstall the top port
plug in the left axle and continue to fill the hydraulic
system through the expansion reservoir. The right
side axle should fill up to the bottom on the top
port plug after adding an additional one quart of
oil. Reinstall the top port plug on the right axle and
fill the hydraulic expansion reservoir to the proper
level as explained in Section 7.2.
15. While in the operator's position, run the engine at
1/2 throttle. Release the parking brake, move the
steering control levers to full forward and reverse 5
to 6 times. It may be necessary to repeat steps 12 to
15 until the air is completely purged from the system.
16. Check the hydraulic system oil level as explained in
Section 7.2.
9. Reinstall the hydraulic expansion reservoir cap.
7.3 Engine Oil
10. The hydraulic system will need to be purged of
all air. Raise the rear of the machine so the drive
wheels are off the ground. Use jackstands and block
the front caster wheels to prevent the machine from
moving.
A. Checking Engine Crankcase Oil Level
The engine oil level should be checked after every 8 hours
of operation or daily as instructed in the Engine Operator’s
Manual furnished with this mower.
11. Move the dump valve control levers to the
"freewheel" position. See Figure 7-4.
B. Changing Engine Crankcase Oil

7.6 Battery
A. Charging the Battery
Refer to the battery charger’s manual for specific
instructions.
WARNING
Under normal conditions the engine’s alternator will have
no problem keeping a charge on the battery. If the battery
has been completely discharged for a long period of time,
the alternator may not be able to recharge the battery, and
a battery charger will be required.
Lead-acid batteries produce flammable and
explosive gases. To avoid personal injury when
checking, testing or charging batteries, DO NOT
use smoking materials near batteries. Keep arcs,
sparks and flames away from batteries. Provide
proper ventilation and wear safety glasses.
DO NOT charge a frozen battery. It may explode and cause
injury. Let the battery warm before attaching a charger.
Whenever possible, remove the battery from the mower
before charging and make sure the electrolyte covers the
plates in all cells.
WARNING
WARNING
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to cause cancer and reproductive harm.
Wash hands after handling.
BATTERIES PRODUCE EXPLOSIVE GASES.
Charge the battery in a well ventilated space so
gases produced while charging can dissipate.
WARNING
Charging rates between 3 and 50 amperes are satisfactory
if excessive gassing or spewing of electrolyte does not
occur or the battery does not feel excessively hot (over
125°F). If spewing or gassing occurs or the temperature
exceeds 125°F, the charging rate must be reduced or
temporarily stopped to permit cooling.
Electric storage battery fluid contains sulfuric
acid which is POISON and can cause SEVERE
CHEMICAL BURNS. Avoid contact of fluid with
eyes, skin, or clothing. Use proper protective gear
when handling batteries. DO NOT tip any battery
beyond 45° angle in any direction. If fluid contact
does occur, follow first aid suggestions below.
B. Jump Starting
1. The booster battery must be a 12 volt type. If a
vehicle is used for jump starting, it must have a
negative ground system.
BATTERY ELECTROLYTE FIRST AID
2. When connecting the jumper cables, connect the
positive cable to the positive battery post, then
connect the negative cable to the negative battery
post.
External Contact — Flush with water.
Eyes — Flush with water for at least 15 minutes
and get medical attention immediately.
Internal — Drink large quantities of water. Follow
with Milk Of Magnesia, beaten egg, or vegetable
oil. Get medical attention immediately. In case of
internal contact, DO NOT give fluids that would
induce vomiting.

7.7 DRIVE BELTS
5. If a blade cutting edge is dull or nicked, it should be
sharpened. Remove the blades for sharpening. See
"Blade Replacement."
All drive belts are spring-loaded and self-tensioning,
however after the first 2, 4, 8 and 10 hours of operation,
the belts should be checked for proper alignment and wear.
Thereafter, check the belts after every 40 hours of operation
or weekly, whichever occurs first.
- NOTE Keep the blades sharp. Cutting with dull blades not
only yields a poor mowing job, but slows the cutting
speed of the mower and causes extra wear on the
engine and the blade drive by pulling hard.
- NOTE If you experience frequent belt wear or breakage,
see your authorized Scag service center for belt
adjustment.
B. Blade Sharpening
- NOTE If possible, use a file to sharpen the blade. Using
a wheel grinder may burn the blade.
WARNING
If the pump drive belt fails, steering control will be
lost which could result in serious injury or death.
Replace the pump drive belt as needed or every
400 hours / 2 years, whichever occurs first.
- NOTE DO NOT sharpen the blades beyond 1/3 of the
width of the blade. See Figure 7-8.
1. Sharpen the cutting edge at the same bevel as the
original. See Figure 7-8. Sharpen only the top of the
cutting edge to maintain sharpness.

for by the owner. Scag’s responsibility is limited to making the required repairs and no claim of breach of warranty shall be cause for
cancellation or rescission of the contract of sale of any Scag mower. “Non-Commercial” use is defined as a single property owner,
where the single property is the residence of the owner of the mower. If the mower is cutting more than the owners single property, it is
deemed commercial use and the “non-commercial” warranty does not apply. Scag Power Equipment reserves the right to deny and / or
void the non-commercial warranty if it believes it to be in commercial use.
This warranty does not cover any mower that has been subject to misuse, neglect, negligence, or accident, or that has been
operated in any way contrary to the operating instructions as specified in the Operator’s Manual. The warranty does not apply

the expiration of the appropriate one year, three year / 500 hour or ninety day warranty period. Scag’s obligation under this warranty is
strictly and exclusively limited to the repair or replacement of defective parts and Scag does not assume or authorize anyone to assume
for them any other obligation. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may
not apply to you.
Scag assumes no responsibility for incidental, consequential or other damages including, but not limited to, expense for gasoline,
expense of delivering the mower to an Authorized Scag Service Dealer and expense of returning it to the owner, mechanic’s travel time,
telephone or telegram charges, rental of a like product during the time warranty repairs are being performed, travel, loss or damage to
personal property, loss of revenue, loss of use of the mower, loss of time or inconvenience. Some states do not allow the exclusion or
limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you
specific legal rights, and you may also have other rights which vary from state to state.
