IMPORTANT SAFETY PRECAUTIONS
This symbol is used to call attention to safety 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
dependent 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 maintenance procedures. Read this manual and review the safety precautions often until you know the limitations.
ACCIDENT PATTERNS TO AVOID
1. CONTACT WITH THE ROTATING BLADE - This accident usually happens when the operator is clearing 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 discharge chute or from under the mower housing. Bystanders are particularly vulnerable.
3. GRASS DISCHARGE CHUTE - 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.
MOWERRUNNING OVERTHEVICTIM - This usually happenswhen a riding mower is driveninreverse.
5.
The accident victims are most often young children whom, unseen by the operator of the mower, were
in the area being mowed.
WE SHARE YOUR DESIRE TO PROTECT YOURSELF, YOUR FAMILY, YOUR FRIENDS AND YOUR
NEIGHBORS FROM ACCIDENTAL INJURY. OBSERVING AND ENFORCING THE FOLLOWING GUIDE
LINES WILL HELP TO INSURE THE SAFETY OF EVERYONE.
SAFETY INSTRUCTIONS AND RECOMMENDATIONS
1. PEOPLE WHO OPERATE, SERVICE, OR ARE OTHERWISE ASSOCIATED with the Zero Turning
Riding Mower should be trained in its proper use and warned of its dangers. Before operating, adjusting,
or servicing the Zero Turning Riding Mower they should read and understand this entire manual and the
engine manual.
2. AVOID CONTACT WITH 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 chute.
3. AVOID HILLS 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 SHOULD LEARN HOW TO STEER the Zero Turning 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 CONTINUED
6. KNOW HOW 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 THE 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 CHILDREN TO OPERATE MOWER. Do not allow others who have not had instructions 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 running. 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, ROUGH-SOLED WORK SHOES AND CLOSE-FITTING TROUSERS AND SHIRTS.
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 equipment moving parts.
12. NEVER CARRY PASSENGERS.
13. KNOW THE 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 THE 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 THE 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 THE MOWER or the gasoline storage container. Gasoline fumes can easily 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 TIGHT to be sure equipment is in safe working condition, especially blade bolts.
21. VEHICLE SHOULD 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 THE MOWER HOUSING. Step or stand only on the tread areas on the deck.
25. WATCH OUT FOR TRAFFIC near roadways and when crossing roads.
26. THIS MACHINE IS NOT MEANT FOR HIGHWAY OR STREET USE. It is not a recreational vehicle and it should
not be operated as such.
27. WHEN FEASIBLE, DO NOT USE MOWER WHEN GRASS IS WET OR SLIPPERY.
28. MOW ONLY IN DAYLIGHT OR GOOD ARTIFICIAL LIGHT.
6
SAFETY CONTINUED
29. ALWAYS DISENGAGE THE MOWER BLADE CLUTCH 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.
TOWING
1. Use for towing only if equipped with a Rhino 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.

Start Safely
Make The Right Start
Mow only in daylight or good arti cial light conditions.
Avoid serious injury or death from mower-thrown
objects or blade contact:
— Keep chain shields, exible or solid de ector shields
or discharge chutes in place and in good repair.
— Keep bystanders at least 300 ft (92 m) from mowing
operation.
— Never direct mower discharge toward anyone.
— Keep hands, feet and other body parts away from
rotating parts, blades and discharge openings.
— Do not operate mower in transport position.
Do not approach a mower until all motion has stopped.
Mower PTO drive engagement:
— Raise mower to maximum cutting height.
— Engage PTO at low engine rpm.
— Increase engine rpm to mower’s rated rpm PTO speed.
— Lower mower to desired cutting height.
— Stop and shut down immediately if the mower strikes
an obstruction.
— Inspect and repair any mower damage before
resuming mowing.
— Do not operate mower with severe vibrations or with
unusual noise.
Rotating Blades –
Keep Away
Do Not Operate a
Damaged Mower
Mower-Thrown Objects
Depending on the designed purpose, mowers are
designed to cut grass, weeds, brush and crops. The
mower blades have been designed and tested for
rugged use. The mower blades, however, are not
intended to contact solid objects like rocks, concrete
or metal. Such impact can cause broken objects to be
thrown up to 300 ft (92 m). Bystanders should never
be within 300 ft (92 m) of an operating rotary mower or
within 100 ft (30 M) of a properly equipped disc mower.
Operate Safely
Mower shielding is designed to reduce the risk of thrown
objects and must be properly maintained and in place
during mowing operations.
The risk of serious injury or death from thrown objects
can be signi cantly reduced by following three rules.
If all of these safety rules are not followed, the
mowing operation must be stopped if anyone comes
within the safety limit for the mower type.
First — Inspect the area prior to mowing and remove
stones, branches, wire, cable, metal, glass and other
solid objects before operating. Any objects that cannot
be removed must be clearly marked and carefully
avoided by the operator.
In non-crop areas with grass and weeds high enough to
hide objects that could be struck by the blades, inspect
the area and remove or mark large debris or obstacles.
Mow the area at an intermediate height. Inspect the area
closely and remove or mark any remaining debris or
obstacles. Mow again at desired nal height.
Follow
All Mower
Safety Rules
Second — Mower-thrown object shielding must be
used when operating near roads, parks, populated
areas or other areas where thrown objects could
injure bystanders or damage property. Follow the
manufacturer's operator's manual.
Third — Cross diagonally when mowing through
ditches, sharp dips, and drops. Raise the mower to
prevent the mower blades from hitting the ground.
13
Mower-Thrown Objects (continued)
Operate Safely
Disc Mowers — When using a disc mower it is
important to know the area to be mowed. If the operator
has mowed the eld before and is familiar with all
obstacles that may be present, it is suf cient to watch
ahead of the mower path for any additional objects that
may have entered the eld. Be ready to stop or avoid
any objects that could be hazardous if thrown by the
mower. If you plan to mow an unfamiliar eld and it is
next to a traveled road or people may be within 100
ft (30 m) of the mower you must inspect, and clean or
mark the eld.
Mowing In Reverse
Do not mow while traveling in reverse. Objects are more
likely to be thrown and can travel further.
Shut off the PTO, wait for the blades to stop turning,
raise the mower, and then back up.
Mow traveling in the forward direction.
Do Not Mow
in Reverse
Use Proper
Ground Speed
Mowing Ground Speed
Proper ground speed depends on terrain conditions and
grass type, density and height to be cut:
— Normal ground speed range is 2 to 5 mph.
— Use slower ground speed for mowing tall, dense grass.
— Use faster ground speed for mowing medium height,
thin grass and under smooth terrain conditions.
— Use slower ground speed for mowing in rough,
sloping or unfamiliar terrain.
Disc mowers are designed to use faster ground speeds
for operating in elds clear of debris and surface hazards.
Operate Safely
Extremely Tall Grass Mowing
You may need to mow extremely tall, non-crop grass
twice. (See page 13, Mower-Thrown Objects.)
First mowing pass:
— Shut the mower and tractor down using proper
equipment shut down practice before dismounting
tractor. (See page 18, Proper Equipment Shut Down
Practices.)
— Inspect the area and remove or mark debris and
obstacles.
— Cut grass higher (10-15 inches) to avoid hidden objects.
Second mowing pass:
— Shut the mower and tractor down using proper
equipment shut down practice before dismounting
tractor.
— Inspect the area and remove or mark debris and
obstacles.
— Cut grass at desired height and, when possible,
90 degrees to the rst mowing pass.
Stop Blade
Before
Unclogging
Provide Adequate
Clearance for

Under Mount Mower Safety Practices
When mowing with an under mount mower:
— Keep removable discharge chute in place and over
discharge opening.
— Never stand on a mower housing when the tractor
engine is operating.
— Distribute grass clippings with discharge chute facing
mowed area.
— Before clearing a clogged mower or discharge
chute, shut down your machine using proper
equipment shut down practice. (See page 18, Proper

Wing And Side Mount Mowers Safety Practices
Raised wing positions reduce shielding protection and
increases the thrown object and blade contact hazard
risks.
Avoid possible serious injury or death by thrown
objects or blade contact from raising and lowering
wings during mowing operations:
— Do not mow with bystanders within 300 ft (92 m) of
the mower.
— Be sure no one is near mower while raising or
lowering wings.
— Shut off the PTO and wait for all rotating elements to
stop before raising the mower deck or wing section.
— Only raise wing to clear objects in the mowing path
or to match ground slope.
— Lower raised wing to ground after clearing object or
ground slope conditions.
— Stop mowing if anyone approaches within 300 ft
(92 m) of mowing area.

Ditch Bank Mowing Safety Practices
Use extreme care when mowing ditch banks. Watch for
washouts, eroded areas and mowing obstructions along
the ditch banks. Hitting obstructions with side-mount
or boom mowers may swerve the tractor’s front end
toward the ditch.
Operate Safely
Raised wing and boom mower ditch bank operations may
reduce the mower’s thrown object shielding effectiveness
for the mower operator’s protection.
— Use enclosed ROPS cabs, special protective
enclosures and other operator shielding available from
the manufacturer when performing these operations.
— Inspect mowing area and remove or mark all foreign
objects and debris to be avoided by mower.
Uneven Terrain Mowing Safety Practices
Tractor and mower stability is reduced on slopes and
uneven terrain.
As in all conditions when mowing, use tractors
equipped with ROPS and seat belt. Make sure the
ROPS are raised and locked in place and always
wear your seat belt.
Prevent tractor and mower overturns and maintain
equipment stability control:
— Review tractor and mower operator’s manuals for
operating safety practices on slopes and uneven
terrain conditions. Explain the practices to those
users and operators who cannot read.
— Avoid extremely steep slope operations.
