SAFETY
SAFE OPERATION PRACTICES FOR RIDE-ON MOWERS
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., which 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.
• Do not operate the mower without either the entire
grass catcher or the guard in place.
• Slow down before turning.
• 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.
• If the collection system has front weights included,
DO NOT operate mower with the grass catcher
unless the front weights are installed.
• Keep machine free of grass, leaves or other debris
buildup which can touch hot exhaust/engine parts
and burn. Do not allow the mower deck to plow
leaves or other debris which can cause buildup to
occur.
• 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
• Use extra care with grass catchers or other
attachments. These can change the stability of the
machine.
• 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.
• 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.
SERVICE
• The operation of any mower can result in foreign
objects thrown into the eyes, which can result in
severe eye damage. Always wear safety glasses
or eye shields while operating the mower or
performing any adjustments or repairs. Wide vision
safety mask over spectacles or standard safety
glasses are recommended.
• Keep nuts and bolts, especially blade attachment
bolts, tight and keep equipment in good condition.
• Never tamper with safety devices. Check there
proper operation regularly.
• 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.

OPERATION
TIPS FOR IMPROVED BAGGING
Follow the mower operation instructions in the 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 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.
STORAGE
When grass catcher is to be stored for a period of
time, clean it thoroughly, remove all dirt, grass, leaves,
etc. Store in a clean, dry place.
CAUTION
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.
CAUTION
Do not leave grass in bagger containers. Empty
containers after each use and before storing.
Failure to do so may result in spontaneous
combustion which could develop into a fire.
