MPORTANT SAFETY PRECAUT ONS
This symbol is used to call attention to safe-
ty precautions that should be followed by
the operator to avoid accidents. When you
see this symbol, carefully read the message
that follows and heed its advice. Failure to
comply with safety precautions could result
in serious bodily injury.
In addition to the design and configuration of equipment, hazard control and accident prevention are depen-
dent upon the awareness, concern, prudence and proper training of personnel in the operation, transport,
maintenance and storage of equipment. Lack of attention to safety can result in accident, personal injury,
reduction of efficiency and worst of all—loss of life. Watch for safety hazards and correct deficiencies
promptly. Use the following safety precautions as a general guide to safe operations when using this
machine. Additional safety precautions are used throughout this manual for specific operating and mainte
nance procedures. Read this manual and review the safety precautions often until you know the limitations.
ACC DENT PATTERNS TO AVO D
1. CONTACT WIT T E ROTATING BLADE - This accident usually happens when the operator is clear-
ing the discharge chute of grass, (especially when the grass is wet), or when the operator adjusts the
machine without turning it off and waiting for the blades to completely stop.
2. PROPELLED OBJECTS - Sticks, rocks, wires, and other objects can be propelled out through the dis-
charge chute or from under the mower housing. Bystanders are particularly vulnerable.
3. GRASS DISC ARGE C UTE - The mower shall not be operated without the grass discharge chute
in its lowered position.
4. OVERTURNING - This happens when riding mowers are used on steep slopes, embankments or hills.
The operator in these cases can come in contact with blades or sustain injuries during a fall.
5. MOWER RUNNING OVER T E VICTIM - This usually happens when a riding mower is driven in
reverse. The accident victims are most often young children whom, unseen by the operator of the
mower, were in the area being mowed.

NE GHBORS FROM ACC DENTAL NJURY. OBSERV NG AND ENFORC NG THE FOLLOW NG GU DE
L NES W LL HELP TO NSURE THE SAFETY OF EVERYONE.
SAFETY NSTRUCT ONS AND RECOMMENDAT ONS
1. PEOPLE W O OPERATE, SERVICE, OR ARE OT ERWISE ASSOCIATED with the Zero Turn Riding Mower
should be trained in its proper use and warned of its dangers. Before operating, adjusting,
or servicing the Zero Turn Riding Mower they should read and understand this entire manual and the
engine manual.
2. AVOID CONTACT WIT MOVING PARTS. Keep hands and feet from under mowing deck and away
from blades at all times. Turn engine (motor) off if you must unclog the discharge chute.
3. AVOID ILLS AND SLOPES. Use EXTREME caution when mowing and/or turning on slopes as loss of traction
and/or tip-over could occur. Drive slower on slopes. DO NOT mow slopes greater than 15 degrees. Watch for
ditches, holes, rocks, dips and rises, which change the operating angle. Keep away from drop-offs and steep
banks. Avoid sudden starts when mowing uphill - mower may tip backwards. Loss of traction may occur going
downhill - weight transfer to the front wheels may cause drive wheels to slip and cause loss of braking. DO NOT
mow slopes when grass is wet - slippery conditions affect steering and reduce traction and braking. The operator is
responsible for safe operation on slopes.
4. DISENGAGE POWER TO MOWER BEFORE BACKING UP. Do not mow in reverse unless absolutely
necessary and then only after turning around and observing the entire area behind the mower. Go slowly.
Most “running over victim” accidents occur in reverse.
5. BEGINNING OPERATORS S OULD LEARN OW TO STEER the Zero Turn Riding Mower before
attempting to mow. Start with slow engine speed and drive without the blades engaged in open area until
comfortable with the machine.
5

SAFETY CONT NUED
6. KNOW OW TO STOP QUICKLY. Know the location and operation of every control, especially how to brake and
how to disengage the mower blades.
7. DO NOT MOVE T E CONTROL LEVERS from forward position to reverse position rapidly. The speed
and/or direction of travel is affected instantly by movement of the Control Levers.
8. DO NOT ALLOW C ILDREN TO OPERATE MOWER. Do not allow others who have not had instruc-
tions to operate mower. Do not operate the mower when children or others are in the area.
9. ALWAYS TURN ENGINE OFF AND REMOVE KEY before leaving mower to prevent children and
inexperienced operators from starting the engine. Never leave the mower unattended with engine run-
ning. Always wait for all moving parts and all sounds to stop before leaving operator’s seat. Always set
the parking brake on an unattended mower.
10. WEAR STURDY, ROUG -SOLED WORK S OES AND CLOSE-FITTING TROUSERS AND S IRTS.
Never operate mower in bare feet, sandals or sneakers.
11. WEAR PERSONAL PROTECTIVE EQUIPMENT such as, but not limitied to, protection for eyes, ears, feet, hands
and head when operating or repairing equipment. Do not wear loose clothing or jewelry that may catch on equip-
ment moving parts.
12. NEVER CARRY PASSENGERS.
13. KNOW T E AREA YOU ARE TO MOW. Watch for hidden dangers such as rocks, roots, sticks, holes,
bumps, and drop-offs, etc. Before mowing, pick up all debris in area to be mowed. Sharp and hard
objects can be propelled at a high speed and can act like shrapnel. Walk through tall grass BEFORE
MOWING to make sure there are no hidden dangers. Mow higher than desired in tall grass to expose
any hidden objects and/or obstacles, clean the area, and then mow to the desired height.
14. BE SURE T E AREA IS CLEAR of other people before mowing. Stop machine if anyone enters the area.
15. NEVER REFUEL A MOWER INDOORS. Allow the engine time to cool before refueling. Unseen vapors may be
ignited by a spark. Always clean up spilled gasoline. Never run the engine indoors in a garage
or any other closed building. Allow engine to cool before storing in any enclosure. The engine exhaust
and gasoline fumes are dangerous.
16. NEVER REMOVE T E FUEL CAP or add gasoline to a running or hot engine or an
engine that has not been allowed to cool for several minutes after running. Always make sure the gas
cap is in place.
17. DO NOT SMOKE AROUND T E MOWER or the gasoline storage container. Gasoline fumes can easi-
ly ignite.
18. KEEP GASOLINE IN A WELL-VENTILATED AREA away from your living quarters and in tightly
capped safety cans. Never store mower with gasoline in the tank inside a building where fumes may
reach open flame or spark.
19. DISENGAGE BLADES, STOP ENGINE, ENGAGE PARKING BRAKE AND REMOVE IGNITION KEY before any
servicing. Be sure all moving parts and all sounds have stopped. Let engine cool and disconnect the spark plugs so
the engine cannot start by accident.
20. KEEP ALL NUTS, BOLTS, AND SCREWS TIG T to be sure equipment is in safe working condition, espe-
cially blade bolts.
21. VE ICLE S OULD BE STOPPED AND INSPECTED FOR DAMAGE after striking a foreign object and
the damage should be repaired before restarting and operating the equipment. Stop immediately and
check for damage or loose parts if mower should start vibrating.
22. DISENGAGE BLADES BEFORE DRIVING ACROSS WALKS or projecting objects or transporting.
23. KEEP SAFETY DEVICES AND GUARDS IN PLACE. If any of the safety switches become inoperable,
have them repaired immediately.
24. DO NOT STEP OR STAND ON T E MOWER OUSING. Step or stand only on the tread areas on the deck.
25. WATC OUT FOR TRAFFIC near roadways and when crossing roads.
26. T IS MAC INE IS NOT MEANT FOR IG WAY OR STREET USE. It is not a recreational vehicle and it should not
be operated as such.
27. W EN FEASIBLE, DO NOT USE MOWER W EN GRASS IS WET OR SLIPPERY.
28. MOW ONLY IN DAYLIG T OR GOOD ARTIF ICIAL LIG T.

SAFETY CONT NUED
29. ALWAYS DISENGAGE T E MOWER BLADE CLUTC when transporting.
30. Do not operate the mower under influence of drugs or alcohol.
31. Do not change the engine governor settings or overspeed the engine. Operating an engine at excessive speed may
increase the hazard of personal injury.
TOW NG
1. Use for towing only if equipped with a Bush og hitch kit. Do not attach towed equipment except at the hitch point.
2. Never allow children or others in or on towed equipment.
3. On slopes, the weight of the towed equipment may cause loss of traction and loss of control.
4. Travel slowly and allow extra distance to stop.
SLOPE OPERAT ON
1. 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.
2. See inside of the back cover to determine the approximate slope angle of the area to be mowed.
3. Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water. This area can be dangerous.
4. Progressively greater care is needed as the slope increases.
5. Always avoid sudden starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly down the slope.
6. Avoid sudden starts when mowing uphill. Mower may tip backwards.
7. Be aware that loss of traction may occur going downhill. Weight transfer to the front wheels may cause drive wheels to slip and
cause loss of braking and steering.
8. Watch for ditches, holes, rocks, dips, and rises that change the operating angle, as rough terrain could overturn the machine. Tall
grass can hide obstacles.
9. Remove or mark obstacles such as rocks, tree limbs, etc. from the ,mowing area. Tall grass can hide obstacles.
10. Use extreme care with grass catches or attachments. These can change the stability of the machine and cause loss of control.
11. Follow the manufacturer’s recommendations for counterweights to improve stability.
12.. Check carefully for overhead clearances (ie. branches, doorways, and electrical wires) before driving under objects and do not
contact them.

f the operator is inexperienced with the zero
turn mower lever steering/speed control, he/she
should follow these recommendations:
Disengage the mower blades. Go very slowly
until thoroughly familiar with the machine. Keep
away from fences, buildings, and other obstruc-
tions. While becoming familiar with the machine,
move the Control Levers smoothly and slowly.
Practice until operation is smooth and efficient.
10. A roll-over protection system (ROPS) is installed
on your machine. Operate unit with the ROPS in
the raised and locked position and use seat belt.
There is no roll-over protection when the ROPS
is down. If it is necessary to lower the ROPS, do
not wear seat belt. Raise the ROPS as soon as
clearance permits.
11. TO DRIVE: Adjust seat forward or backward for
operator comfort. Move the Control Levers to the
“IN” position. Move Control Levers forward to
move forward. Move levers slowly forward to
increase speed. To reverse direction, move the
Control Lever on the side to which you want to
turn slightly rearward of the other Control Lever.
To turn on a zero radius axis, go slowly and pull
one Control Lever back and push the other

WARN NG
Use EXTREME caution when mowing and/or
turning on slopes as loss of traction and/or
tip-over could occur. Drive slower on
slopes. DO NOT mow slopes greater than 15
degrees. Watch for ditches, holes, rocks,
dips and rises, which change the operating
angle. Keep away from drop-offs and steep
banks. Avoid sudden starts when mowing
uphill - mower may tip backwards. Loss of
traction may occur going downhill - weight
transfer to the front wheels may cause drive
wheels to slip and cause loss of braking. DO
NOT mow slopes when grass is wet - slip-
pery conditions affect steering and reduce
traction and braking. The operator is respon-
sible for safe OPERAT ON ON SLOPES.
15. TO STOP:
A. Slow engine speed with throttle to slowest
position
B. Disengage the mower blade clutch by mov-
ing the PTO clutch switch to the “OFF” position.
C. Move Control Levers to neutral position and

operation of the mower. Check tire air pres-
sure periodically. Inflate front and rear tires to 15 psi.

MOTON CONTROL STEERNG ADJUSTMENT
1. Raise the drive wheels of the Zero Turn
off of the ground. Safely block the frame
in this position so it is secure. This
adjustment must be made with the drive
wheels turning.
2. Remove the electrical connection from
the seat switch and temporarily install a
jumper wire across the terminals of the
wiring harness.
3. Loosen the jamnuts on the hex turnbuckle,
which connects the lever control arm to
the pump control arm. Note: the nuts to
the front of the hex turnbuckle have left-
handed threads.
4. Start the engine. Run the engine at full
throttle and release brake.
5. Position the control levers in the neutral
position. If the drive wheels creep
(rotate) in the neutral position then
lengthen or shorten the turnbuckle
assembly. Make the adjustment to stop
the wheel from rotating.
6. Re-tighten the nuts at the end of the hex
turnbuckles and repeat the procedure for
the opposite side of the unit.
7. Shut the unit off. Remove the jumper wire from
the wiring harness and replace the connectors
into the seat switch. Never operate the mower
unless all safety switches are operating properly.
DR VE ADJUSTMENTS
Steering and motion controls should be uniform in all
forward and reverse speeds. From the reverse posi-
tion the levers should automatically return to neutral
when released.
TEST DR VE OPERAT ONS
