 OPERATION

Safe Operating Practices

This product is capable of amputating hands and feet and 

throwing objects. Always follow all safety instructions to avoid 
serious injury or death.

Safe Operation

Evaluate the terrain to determine what accessories and 
attachments are needed to properly and safely perform 
the job. Only use accessories and attachments approved 
by the manufacturer.

Never leave a running mower unattended. Always stop 
on level ground, disengage deck clutch, place steering 
control levers in park brake position, stop the engine, and 
remove ignition key before leaving operator’s seat for 
any reason. Wait for engine and all moving parts to come 
to a complete stop before leaving the mower for any rea-
son including emptying the catcher or unclogging the 
chute.

Do not change the engine governor setting or overspeed 
the engine. Operating the engine at excessive speed may 
increase the hazard of personal injury.

Always remain seated while operating mower.

Always keep safety shields and covers in place, except 
for servicing.

Always maintain a safe distance from people and pets 
when mowing. Always stop mower if someone enters the 
area.

Always operate mower in daylight or with adequate 
working lights. 

Follow daily and weekly checklists, making sure hoses 
are tightly secured and bolts are tightened.

Always observe traffic laws while driving mower from 
one location to another. Watch for traffic when operating 
near or crossing roadways.

Always be alert for hazards such as rocks, metal objects 
and other debris which may be thrown or entangled by 
mower blades. Watch out for holes or deep depressions.

Inspect area to be mowed for hazards such as rocks, 
metal objects and other debris which may be thrown or 
entangled by mower blades. Remove these objects before 
mowing.

Always inspect mower for damage after striking a foreign 
object. If damage is found, repair mower immediately. 

Be 

sure to stop on level ground,

 disengage deck clutch, set 

park brake, stop the engine, and remove the ignition 
switch key when leaving the operator’s seat to inspect 
damage.

Always wear adequate ear protection, such as earplugs, 
when operating this equipment as prolonged exposure to 
uncomfortable or loud noises can cause impairment or 
loss of hearing. Do not wear radios or music headphones 
while operating the machinery. Safe operation requires 
your full attention.

Do not operate the equipment while wearing sandals, ten-
nis shoes, sneakers, shorts or any type of loose fitting 

clothing. Do not use a towel as a headband or neck wrap 
and do not hang towel from the waist. Long hair, loose 
clothing or jewelry may get tangled in moving parts. 
Always wear long pants, safety glasses, ear protection 
and safety shoes when operating this mower. 

Always be aware of what is behind the mower before 
backing up. Never mow in reverse. Always look down 
and behind before and while backing up.

Never push forward suddenly on your steering control 
levers while the mower is in rearward motion because 
mower may tip backwards.

Never pull back suddenly on your steering control levers 
while the mower is in forward motion.

When mowing in reverse, push forward slowly on the 
steering control levers and avoid sudden movement. 
rapid movement of the steering control levers in either 
direction could result in a reaction of the mower that can 
cause serious injury.

Never operate a poorly maintained mower.

Never attempt high speed maneuvering, especially in 
crowded or congested areas.

Never allow persons to operate this mower without 
proper instruction or allow children to operate mower. 
Allow only responsible adults who are familiar with 
these instructions to operate this mower.

Never put hands or feet under any part of the mower 
while it is running.

Never carry passengers.

Never direct discharged material toward anyone. Avoid 
discharging material against a wall or obstruction. Mate-
rial may ricochet back towards the operator. Always dis-
engage the mower blades and wait for them to stop 
before crossing gravel drives, walks or roads.

Always keep clear of the mower blades and attachments 
during their operation.

Do not use any unauthorized attachment or modify the 
mower.

Turn off mower blades when not mowing.

Slow down before turning.

Stop the engine before removing the grass catcher or 
unclogging the discharge chute. Never clear the discharge 
chute with the engine running. Turn off the engine and be 
sure the blades have stopped before cleaning. Use a stick 
to clear a plugged discharge area. 

Never use your hand!

Do not operate the mower if you are fatigued, sick or 
while under the influence of alcohol or drugs, if your are 
pregnant or under 18 years old.

Exercise caution when loading or unloading the mower 
onto a trailer or truck.

Always wear safety goggles or safety glasses with side 
shields when operating the mower.

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