SAFETY RULES

Safe Operation Practices for Ride-On Mowers

DANGER: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROW ING OBJECTS. FAILURE
TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.

WARNING: In order to prevent ac ci den tal
starting when setting up, trans port ing,
ad just ing or making repairs, al ways
dis con nect spark plug wire and place
wire where it can not contact spark plug.

WARNING: Do not coast down a hill in neu­tral, you may lose control of the tractor.

WARNING: Tow only the attachments
that are rec om mend ed by and comply
with spec i fi ca tions of the man u fac tur er
of your tractor. Use common sense
when towing. Operate only at the low est
possible speed when on a slope. Too
heavy of a load, while on a slope, is
dan ger ous. Tires can lose trac tion with
the ground and cause you to lose control
of your tractor.

• Do not operate the machine while under the influence
of alcohol or drugs.

• Watch for traffic when operating near or crossing
road ways.

• Use extra care when loading or unloading the machine
into a trailer or truck.

• Always wear eye protection when operating
machine.

• Data indicates that operators, age 60 years and above,
are involved in a large percentage of riding mower­related injuries. These operators should evaluate their
ability to operate the riding mower safely enough to
protect them selves and others from serious injury.

• Follow the manufacturer's recommendation for wheel
weights or counterweights.

• Keep machine free of grass , leaves or other debris
build-up which can touch hot exhaust / engine parts
and burn. Do not allow the mower deck to plow leaves
or other debris which can cause build-up to occur.
Clean any oil or fuel spillage before operating or storing
the machine. Allow machine to cool before storage.

I. GENERAL OPERATION

• Read, understand, and follow all instructions on the
machine and in the manual before starting.

• Do not put hands or feet near rotating parts or under
the machine. Keep clear of the discharge opening at
all times.

• Only allow responsible adults, who are familiar with
the in struc tions, to operate the machine.

• Clear the area of objects such as rocks, toys, wire, etc.,
which could be picked up and thrown by the blades.

• Be sure the area is clear of bystanders before
operating. Stop 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
back ing.

• Never direct discharged material toward anyone. Avoid
discharging material against a wall or obstruction.
Material may ricochet back toward the operator. Stop
the blades when crossing gravel surfaces.

• Do not operate machine without the entire grass catcher,
discharge chute, or other safety devices in place and
working.

• Slow down before turning.

• Never leave a running machine unattended. Always
turn off blades, set parking brake, stop engine, and
remove keys before dismounting.

• Disengage blades when not mowing. Shut off engine
and wait for all parts to come to a complete stop before
cleaning the machine, removing the grass catcher, or
unclogging the discharge chute.

• Operate machine only in daylight or good artificial
light.

II. 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.

• Mow up and down slopes, not across.

• Watch for holes, ruts, bumps, rocks, or other hidden
objects. Uneven terrain could overturn the machine.
Tall grass can hide obstacles.

• Choose a low ground speed so that you will not have
to stop or shift while on the slope.

• Do not mow on wet grass. Tires may lose traction.

Always keep the machine in gear when going down

slopes. Do not shift to neutral and coast downhill.

• Avoid starting, stopping, or turning on a slope. If the
tires lose traction, disengage the blades and proceed
slowly straight down the slope.

• Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction,
which could cause the machine to roll over.

• Use extra care while operating machine with grass
catchers or other at tach ments; they can affect the
stability of the machine. Do no use on steep slopes.

• Do not try to stabilize the machine by putting your foot
on the ground.

• Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly roll over if a wheel is over
the edge or if the edge caves in.

SAFETY RULES

Safe Operation Practices for Ride-On Mowers

III. CHILDREN

Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted to
the ma chine and the mowing activity. Never assume that
children will remain where you last saw them.

• Keep children out of the mowing area and in the watchful
care of a responsible adult other than the operator.

• Be alert and turn machine off if a child enters the
area.

• Before and while backing, look behind and down for
small children.

• Never carry children, even with the blades shut 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 machine.

• Never allow children to operate the machine.

• Use extra care when approaching blind corners, shrubs,
trees, or other objects that may block your view of a child.

IV. TOWING

• Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the
hitch point.

• Follow the manufacturer's recommendation for weight
limits for towed equipment and towing on slopes.

• 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.

V. SERVICE

SAFE HANDLING OF GASOLINE

To avoid personal injury or property damage, use extreme
care in handling gasoline. Gasoline is extremely flammable
and the vapors are explosive.

• Extinguish all cigarettes, cigars, pipes, and other
sources of ignition.

• Use only approved gasoline container.

• Never remove gas cap or add fuel with the engine
running. Allow engine to cool before refueling.

• Never fuel the machine indoors.

• Never store the machine or fuel container where there
is an open flame, spark, or pilot light such as on a water
heater or other appliances.

• Never fill containers inside a vehicle or on a truck or
trailer bed with plastic liner. Always place containers
on the ground away from your vehicle when filling.

• 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.

• Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete.
Do not use a nozzle lock-open device.

• If fuel is spilled on clothing, change clothing immediately.

• Never overfill fuel tank. Replace gas cap and tighten
securely.

GENERAL SERVICE

• Never operate machine in a closed area.

• Keep all nuts and bolts tight to be sure the equipment
is in safe working condition.

• Never tamper with safety devices. Check their proper
operation regularly.

• Keep machine free of grass, leaves, or other debris
build-up. Clean oil or fuel spillage and remove any fuel­soaked debris. Allow machine to cool before storing.

• If you strike a foreign object, stop and inspect the
machine. Repair, if necessary, before restarting.

• Never make any adjustments or repairs with the engine
run ning.

• Check grass catcher components and the discharge
chute frequently and replace with manufacturer's rec­ommended parts, when necessary.

• Mower blades are sharp. Wrap the blade or wear
gloves, and use extra caution when servicing them.

• Check brake operation frequently. Adjust and service
as required.

• Maintain or replace safety and instruction labels, as
necessary.

• Be sure the area is clear of bystanders before operat­ing. Stop machine if anyone enters the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely necessary.
Al ways look down and behind before and while backing.

• Never carry children, even with the blades shut 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 machine.

• Keep children out of the mowing area and in the watchful
care of a responsible adult other than the operator.

• Be alert and turn machine off if a child enters the
area.

• Before and while backing, look behind and down for
small children.

• Mow up and down slopes (15° Max), not across.

• Choose a low ground speed so that you will not have
to stop or shift while on the slope.

• Avoid starting, stopping, or turning on a slope. If the
tires lose traction, disengage the blades and proceed
slowly straight down the slope.

• If machine stops while going uphill, disengage blades,
shift into reverse and back down slowly.

• Do not turn on slopes unless necessary, and then, turn
slowly and gradually downhill, if possible.
