SAFETY RULES
Safe Operation Practices for Ride-On Mowers
GENERAL SERVICE
III. CHILDREN
•
Never operate machine in a closed area.
Keep all nuts and bolts tight to be sure the equipment
is in safe working condition.
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.
•
•
•
Never tamper with safety devices. Check their proper
operation regularly.
•
•
•
•
Keepchildrenoutofthemowingareaandinthewatchful
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.
Nevercarrychildren,evenwiththebladesshutoff.They
may fall off and be seriously injured or interfere with
safemachineoperation.Childrenwhohavebeengiven
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.
Useextracarewhenapproachingblindcorners,shrubs,
trees, or other objects that may block your view of a
child.
Keep machine free of grass, leaves, or other debris
build-up. Cleanoilorfuelspillageandremoveanyfuel-
soaked debris. Allow machine to cool before storing.
If you strike a foreign object, stop and inspect the
machine. Repair, if necessary, before restarting.
Nevermakeanyadjustmentsorrepairswiththeengine
running.
Check grass catcher components and the discharge
guard frequently and replace with manufacturer's rec-
ommended 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.

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 equip-
ment.
•
Be sure the area is clear of bystanders before operat-
ing. Stop machine if anyone enters the area.
Never carry passengers.
Do not mow in reverse unless absolutely necessary.
Alwayslookdownandbehindbeforeandwhilebacking.
Nevercarrychildren,evenwiththebladesshutoff.They
may fall off and be seriously injured or interfere with
safemachineoperation.Childrenwhohavebeengiven
rides in the past may suddenly appear in the mowing
area for another ride and be run over or backed over
by the machine.
Keepchildrenoutofthemowingareaandinthewatchful
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.
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.

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.
