Safety
DANGER
DANGER
In certain conditions gasoline is extremely
flammable and vapors are explosive.
In certain conditions during fueling, static
electricity can be released causing a spark
which can ignite gasoline vapors. A fire or
explosion from gasoline can burn you and
others and cause property damage.
A fire or explosion from gasoline can burn
you, others, and cause property damage.
• Fill the fuel tank outdoors in an open
area, when the engine is cold. Wipe up
any gasoline that spills.
• Always place gasoline containers on the
ground away from your vehicle before
filling.
• Never refill the fuel tank or drain the
machine indoors or inside an enclosed
trailer.
• Do Not fill gasoline containers inside a
vehicle or on a truck or trailer bed because
interior carpets or plastic truck bed liners
may insulate the container and slow the
loss of any static charge.
• Do Not fill the fuel tank completely
full. Add gasoline to the fuel tank until
the level is 1/4 to 1/2 inch (6–13 mm)
below the bottom of the filler neck. This
empty space in the tank allows gasoline
to expand.
• When practical, remove gas-powered
equipment from the truck or trailer and
refuel the equipment with its wheels on
the ground.
• Never smoke when handling gasoline,
and stay away from an open flame or
where gasoline fumes may be ignited by
spark.
• If this is not possible, then refuel such
equipment on a truck or trailer from a
portable container, rather than from a
gasoline dispenser nozzle.
• Store gasoline in an approved container
and keep it out of the reach of children.
• If a gasoline dispenser nozzle must be
used, keep the nozzle in contact with the
rim of the fuel tank or container opening
at all times until fueling is complete.
• Add fuel before starting the engine.
Never remove the cap of the fuel tank or
add fuel when engine is running or when
the engine is hot.
WARNING
• If fuel is spilled, Do Not attempt to start
the engine. Move away from the area of
the spill and avoid creating any source of
ignition until fuel vapors have dissipated.
Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors has caused
cancer in laboratory animals. Failure to use
caution may cause serious injury or illness.
• Do Not operate without entire exhaust
system in place and in proper working
condition.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas
tank/container opening.
• Keep away from eyes and skin.
• Never siphon by mouth.
• Check that the operator’s presence controls,
safety switches, and shields are attached and
functioning properly. Do Not operate unless they
are functioning properly.

and operating the mower).
Operation
– Before clearing blockages.
WARNING
– Whenever you leave the mower.
Operating engine parts, especially the
muffler, become extremely hot. Severe burns
can occur on contact and debris, such as
leaves, grass, brush, etc. can catch fire.
• Stop engine, wait for all moving parts to stop, and
engage parking brake:
– Before refueling.
• Allow engine parts, especially the muffler,
to cool before touching.
– Before dumping the grass catcher.
• Remove accumulated debris from muffler
and engine area.
WARNING
Hands, feet, hair, clothing, or accessories can
become entangled in rotating parts. Contact
with the rotating parts can cause traumatic
amputation or severe lacerations.
• Install and maintain in working order a
spark arrester before using equipment
on forest-covered, grass-covered, or
brush-covered unimproved land.
• Do Not operate the machine without
guards, shields, and safety devices in
place and working properly.
WARNING
Engine exhaust contains carbon monoxide,
which is an odorless deadly poison that can
kill you.
• Keep hands, feet, hair, jewelry, or clothing
away from rotating parts.
• NEVER carry passengers. DO NOT operate
the mower when people, especially children, or
pets are in the area.
Do Not run engine indoors or in a small
confined area where dangerous carbon
monoxide fumes can collect.
• Be alert, slow down and use caution when making
turns. Look behind and to the side before
changing directions.
• Operate only in daylight or good artificial light,
keeping away from holes and hidden hazards.
• Stop the blades, slow down, and use caution when
crossing surfaces other than grass and when
transporting the mower to and from the area to
be mowed.
• Be sure all drives are in neutral and parking brake
is engaged before starting engine. Use seat belts.
• Never operate the mower with damaged guards,
shields, or covers. Always have safety shields,
guards, switches and other devices in place and in
proper working condition.
• Be aware of the mower discharge path and direct
discharge away from others.
• Do Not operate the mower under the influence
of alcohol or drugs.

Safety
• Watch for ditches, holes, rocks, dips and rises that
change the operating angle, as rough terrain could
overturn the machine.
DANGER
Operating on wet grass or steep slopes can
cause sliding and loss of control. Wheels
dropping over edges, ditches, steep banks, or
water can cause rollovers, which may result
in serious injury, death or drowning.
• Avoid sudden starts when mowing uphill because
the mower may tip backwards.
• Be aware that loss of traction may occur going
downhill. Weight transfer to the front wheels
may cause drive wheels to slip and cause loss of
braking and steering.
• Do Not mow slopes when grass is wet.
• Do Not mow near drop-offs or near water.
• Always avoid sudden starting or stopping on a
slope. If tires lose traction, disengage the blades
and proceed slowly off the slope.
• Do Not mow slopes greater than 15
degrees.
• Reduce speed and use extreme caution
on slopes.
• Follow the manufacturer’s recommendations for
wheel weights or counter weights to improve
stability.
• Avoid sudden turns or rapid speed
changes.
• Use extreme care with grass catchers or
attachments. These can change the stability of the
machine and cause loss of control.
• See inside the back cover to determine the
approximate slope angle of the area to be mowed.
• Use a walk behind mower and/or a hand trimmer
near drop-offs, ditches, steep banks or water.
Using the Rollover Protection System
(ROPS)
A Rollover Protection System (roll bar) is installed
on the unit.
WARNING
There is no rollover protection when the roll
bar is down. Wheels dropping over edges,
ditches, steep banks, or water can cause

the machine. The levers control the flow of hydraulic
oil from the hydrostatic pump to the drive wheel
motor for each side.
Moving the levers forward or backward turns the
wheel on the same side forward or in reverse. Wheel
speed is proportional to the amount the lever is
moved.
Note: Brake must be engaged, motion control levers
out (neutral lock position) and PTO switch “OFF” to
start engine. (It is not necessary for the operator to
be in the seat to start the engine.)

Operation
WARNING
Loading a unit on a trailer or truck increases
the possibility of backward tip-over.
Backward tip-over could cause serious injury
or death.
• Use extreme caution when operating a
unit on a ramp.
• Use only a single, full width ramp; Do
Not use individual ramps for each side
of the unit.
• If individual ramps must be used, use
enough ramps to create an unbroken
ramp surface wider than the unit.

(41-47 N-m)
• Do Not exceed a 15° angle between ramp
and ground or between ramp and trailer
or truck.
• Avoid sudden acceleration while driving
unit up a ramp to avoid tipping backward.
Transporting
• Avoid sudden deceleration while backing
unit down a ramp to avoid tipping
backward.
Transporting a Unit
Use a heavy-duty trailer or truck to transport the
machine. Lock brake and block wheels. Securely
fasten the machine to the trailer or truck with straps,
chains, cable, or ropes. Be sure that the trailer or truck
has all necessary lighting and marking as required by
law. Secure a trailer with a safety chain.
Loading a Unit
Use extreme caution when loading units on trailers or
trucks. One full width ramp that is wide enough to
extend beyond the rear tires is recommended instead
of individual ramps for each side of the unit. The
lower rear section of the tractor frame extends back
between the rear wheels and serves as a stop for
tipping backward. Having a full width ramp provides
a surface for the frame members to contact if the
unit starts to tip backward. If it is not possible to use
one full width ramp, use enough individual ramps to
simulate a full width continuous ramp.
CAUTION
This unit does not have proper turn
signals, lights, reflective markings, or a
slow moving vehicle emblem. Driving on a
street or roadway without such equipment
is dangerous and can lead to accidents
causing personal injury. Driving on a street
or roadway without such equipment may also
be a violation of State laws and the operator
may be subject to traffic tickets and/or fines.
Ramp should be long enough so that the angles
between the ramp and the ground and the ramp and
the trailer or truck do not exceed 15°. A steeper angle
may cause mower deck components to get caught as
the unit moves from ramp to trailer or truck. Steeper
angles may also cause the unit to tip backward. If
loading on or near a slope, position the trailer or
truck so it is on the down side of the slope and the
ramp extends up the slope. This will minimize the
ramp angle. The trailer or truck should be as level
as possible.
Do Not drive a unit on a public street or
roadway.

Operation
Important: Do Not attempt to turn the unit
while on the ramp, you may lose control and
drive off the side.
Avoid sudden acceleration when driving up a ramp
and sudden deceleration when backing down a ramp.
Both maneuvers can cause the unit to tip backward.
