SAFETY RULES
SAFE OPERATION PRACTICES FOR RIDE-ON MOWERS
DANGER !
THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROWING OBJECTS.
FAILURE TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR
DEATH.
GENERAL OPERATION
• Read, understand and follow all instructions in the
manual and on the machine before starting.
• Only allow responsible adults who are familiar with
the instructions to operate the machine.
• Clear the area of objects such as rocks, stones,
toys, wire etc., that could be picked up and
thrown by the blades.
• Be sure the area is clear of all people and pets
before mowing. Stop the machine if anyone enters
the area.
• Never carry passengers or children, even with
blades off.
• Do not mow in reverse unless absolutely
necessary. Always look down and behind before
and while backing.
• Be aware of the mower discharge direction and
do not direct it towards anyone. Do not operate
the mower without either the entire grass catcher
or the guard in place.
• Slow down before turning.
• Never leave the machine unattended when the
engine is running. Always turn off the blades, set
the parking brake, stop the engine and remove
the key before leaving the machine.
• Turn off blades when not mowing.
• Stop engine before removing grass catcher or
unclogging chute.
• Mow only in daylight or good artificial light.
• Do not operate the machine while under the
influence of alcohol or drugs.
• Watch out for traffic when operating near or
crossing roadways.
• Use extra care when loading and unloading the
machine onto a trailer or truck.
• 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 riding
mower safely enough to protect themselves and
others from serious injury.
• Keep machine free of grass, leaves or other
debris buildup that can touch hot exhaust/engine
parts and burn. Do not allow the mower deck
to plow leaves or other debris that can cause
buildup to occur. Clean any oil or fuel spills before
operating or storing the machine. Allow machine
to cool before storage.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and
tip-over accidents, which can result in severe injury or
death. All slopes require extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not
mow it.
DO
• Mow up and down slopes (10° Max.), not across.
• Remove obstacles such as rocks, tree limbs, etc.
• Watch for holes, ruts, or bumps. Uneven terrain
could overturn the machine. Tall grass can hide
obstacles.
• Use slow speed. Choose a low speed so that you
will not have to stop while on the slope.
• Use extra care with grass catchers or other
attachments. These can change the stability of
the machine.
• Keep all movement on the slopes slow and
gradual. Do not make sudden changes in speed
or direction.
• Avoid starting or stopping on a slope. If tires
lose traction, disengage the blades and proceed
slowly straight down the slope.
DO NOT
• Do not turn on slopes unless necessary, and then,
turn slowly and gradually downhill, if possible.
• Do not mow near drop-off, ditches, or
embankments. The mower could suddenly turn
over if a wheel is over the edge of a cliff or ditch,
or if an edge caves in.
• Do not mow on wet grass. Reduced traction
could cause sliding.
• Do not try to stabilize the machine by putting your
foot on the ground.

SAFETY RULES
SAFE OPERATION PRACTICES FOR RIDE-ON MOWERS
CAUTION
In order to prevent accidental starting
when setting up, transporting,
adjusting or making repairs, always
disconnect spark plug wire and place
wire where it cannot contact spark
plug.
WARNING!
DO NOT tow any trailers, etc. with this
mower. They may jackknife or over
turn causing damage to the mower and
possibly serious injury to the operator.
WARNING!
Battery posts, terminals and related
accessories contain lead and lead
compounds, chemicals know to the
State of California to cause cancer
and birth defects or other reproductive
harm. Wash hands after handling.
CHILDREN
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 allow children to operate the machine.
• Keep children out of the mowing area and under
the watchful care of another responsible adult.
• Be alert and turn off the machine if children enter
the area.
• Before and when backing, look behind and down
for small children.
• Never carry children. They may fall off and be
seriously injured or interfere with safe machine
operation.
• Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.
SERVICE
• The operation of any mower can result in foreign
objects being thrown into the eyes, which can
result in severe eye damage. Always wear safety
glasses or eye shields while operating your
mower or performing any adjustments or repairs.
We recommend a wide vision safety mask over
spectacles or standard safety glasses.
• Use extra care in handling gasoline and other
fuels. They are flammable and vapors are
explosive.
- Use only an approved container.
- Never remove gas cap or add fuel with the
engine running.
- Allow engine to cool before refueling.
- Do not smoke.
- Never refuel the machine indoors.
- Never store the machine or fuel container
inside where there is an open flame, such as
a water heater.
• Never run a machine inside a closed area.
• Keep nuts and bolts, especially blade attachment
bolts, tight and keep equipment in good
condition.
• Never tamper with safety devices. Check their
proper operation regularly.
• Keep machine free of grass, leaves, or other
debris buildup. Clean oil or fuel spills. Allow
machine to cool before storing.
• Stop and inspect the equipment if you strike an
object. Repair, if necessary, before restarting.
• Never make adjustments or repairs with the
engine running.
• Grass catcher components are subject to wear,
damage, and deterioration, which could expose
moving parts or allow objects to be thrown.
Frequently check components and replace
with manufacturer’s recommended parts, when
necessary.
• Mower blades are sharp and can cut. Wrap the

OPERATION
TIPS FOR IMPROVED BAGGING
Follow the mower operation instructions in you mower
operator’s manual.
When operating your grass catcher on a lawn where
grass and leaf bagging equipment has not been
used, you are picking up thatch and debris that has
accumulated for long periods of time. The amount
collected and the total time of operation may be
greater than you will experience with regular use of
your grass catcher.
• Always run throttle at full speed when bagging.
• Select a speed low enough to give good mower
cutting performance, good quality cut and good
bagging performance.
NOTE: It may be necessary to overlap width of
cut to suit your conditions.
• If grass is extremely tall, it should be mowed twice.
The first time relatively high, the second time to
desired height.
• Use left hand side of mower for trimming.
• Plastic trash bags (3.0 mil, 30 gallon) can be
inserted inside grass catcher containers for ease
of debris disposal. To remove the plastic trash
bags when full:
a. Disengage blades, shift into neutral, engage
the parking brake and stop the engine.
b. Unlatch and raise cover.
c. Remove one container at a time by grasping
container handles and pulling toward the rear,
off of the tube rails.
d. With the container resting on the ground,
close and secure the top of the plastic lawn
bag.
e. Tip the container on its side and slide the
filled bag from the container.
f. Install a new plastic lawn bag with the edges
of the bag draped over upper lip of the
Container.
g. Repeat for other container.
h. Reinstall containers making sure right
container overlaps left container at center
supports.
i. Close cover and secure latches over center
support tubes.
• Avoid cutting wet grass or in the morning while the
dew is still heavy. Grass clippings collected under
these conditions tend to be sticky and adhere to
the walls of the flow path causing clogging.
• If the grass catcher fails to pick up cut grass
or leaves, it is an indication that clogging has
occurred in the system or that the grass catcher
containers are full.
a. Disengage blades, place motion control levers
in neutral position.
- Unlatch and raise cover.
- Slide out containers and dispose of
clippings.
- Replace containers, close cover, and latch.
b. Unlatch chutes and check for clogging.
- Remove all debris in chute.
- Reassemble and latch chutes.
GENERAL RECOMMENDATIONS
Always observe safety rules when performing any
maintenance.
• Before each use check for loose fasteners.
• Clean unit thoroughly after each use.
BLADE CARE
• For best results mower blades must be kept
sharp. Replace bent or damaged blades.
• See BLADE CARE instructions in your mower
operator’s manual.
CAUTION
BEFORE PERFORMING
MAINTENANCE, SERVICE OR
ADJUSTMENTS:
• Set parking brake.
• Place motion control levers in
NEUTRAL position.
• Place clutch control in
DISENGAGED position.
• Turn ignition key to OFF position.
• Make sure blades and all moving
parts have completely stopped.
• Disconnect spark plug wire(s) from
spark plug(s) and place wire where
it cannot come in contact with plug.
