specifications of the American National Standards
Institute, in effect at the time of production.
However, improper use or maintenance by the
operator or owner can result in injury. To reduce
the potential for injury, comply with these safety
instructions and always pay attention to the safety
alert
symbol, which means CAUTION,
WARNING, or DANGER—“personal safety
instruction.” Failure to comply with the
instruction may result in personal injury or death.
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.
POTENTIAL HAZARD
• Engine exhaust contains carbon monoxide,
which is an odorless, deadly poison.
WHAT CAN HAPPEN
• Carbon monoxide can kill you and is also
known to the State of California to cause
birth defects.
HOW TO AV
OID THE HAZARD
• Do not run engine indoors or in an enclosed
area.
General Operation
1. Read, understand, and follow all instructions in
the operator’s manual and on the machine before
starting.
2. Allow only responsible adults who are familiar
with the instructions to operate the machine.
3. Clear the area of objects such as rocks, toys,
wire, etc., which could be picked up and thrown
by the blade.
4. Be sure the area is clear of other people before
mowing. Stop the machine if anyone enters the
area.
5. Never carry passengers.
6. Do not mow in reverse unless absolutely
necessary. Always look down and behind before
and while backing.
7. Be aware of the mower discharge direction and
do not point it at anyone. Do not operate the
mower without either the entire grass catcher or
the guard in place.
8. Slow down before turning. Sharp turns on any
terrain may cause loss of control.
9. Never leave a running machine unattended.
Always turn off blades, set parking brake, stop
engine, and remove keys before dismounting.
10. Remove both the “ignition” and “Key Choice”
keys and put in a safe place, out of reach of
children, when not using the machine.
11. Turn off blades when not mowing.
12. Keep hands, feet, hair and loose clothing away

17. Use extra care when loading or unloading the
machine onto a trailer or truck.
18. Do not touch equipment or attachment parts
which may be hot from operation. Allow to cool
before attempting to maintain, adjust or service.
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 greater than 5°, not
across.
• Mow downhill only on slopes above 10°, never
mow uphill. If a steep slope must be ascended,
back up the hill, and drive forward down the hill,
keeping the machine in gear.
• Remove obstacles such as rocks, tree limbs, etc.
from the mowing area. Watch for holes, ruts or
bumps, as uneven terrain could overturn the
machine. T
all grass can hide obstacles.
• Use slow speed. Choose a low gear so that you
will not have to stop or shift while on the slope.
• Follow the manufacturer’s recommendations for
wheel weight or counterweights to improve
stability.
• Use extra care with grass catchers or other
attachments. These can change the stability of
the machine.
• Keep all movement on 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 operate machine on hillsides or slopes
exceeding 15
°.
• Avoid turning on slopes. If you must turn, turn
slowly and gradually downhill, if possible.
• Do not mow near drop-offs, ditches, or
embankments. The machine could suddenly turn
over if a wheel goes 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.
• Do not use a grass catcher on steep slopes.
Heavy grass bags could cause loss of control or
overturn the machine.
Safety
4
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. The following requirements must be
followed to prevent injury to children.
1. Keep children out of the mowing area and under
the watchful care of another responsible adult.
2. Be alert and turn the machine off if children
enter the area.
3. Before and while backing, look behind and down
for small children.
4. Never carry children. They may fall off and be
seriously injured or interfere with safe machine
operation.
5. Never allow children to operate the machine.
6. Use extra care when approaching blind corners,
shrubs, trees, the end of a fence or other objects
that may obscure vision.

Adding
Fuel
Use UNLEADED Regular Gasoline suitable for
automotive use (85 pump octane minimum). Leaded
regular gasoline may be used if unleaded regular is
not available.
IMPORTANT: Never use methanol, gasoline
containing methanol, or gasohol containing
more than 10% ethanol because the fuel
system could be damaged. Do not mix oil with
gasoline.
POTENTIAL HAZARD
• In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
• A fire or explosion from gasoline can burn
you, others, and cause property damage.
HOW TO AV
OID THE HAZARD
• Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine is cold.
Wipe up any gasoline that spills.
• Do not fill the fuel tank completely full.
Add gasoline to the fuel tank until the level
is 1/4” to 1/2” (6 mm to 13 mm) below the
bottom of the filler neck. This empty space
in the tank allows gasoline to expand.
• Never smoke when handling gasoline, and
stay away from an open flame or where
gasoline fumes may be ignited by a spark.
• Store gasoline in an approved container
and keep it out of the reach of children.
Never buy more than a 30-day supply of
gasoline.
IMPORTANT: Never use fuel additives
containing methanol or ethanol.
POTENTIAL HAZARD
• When fueling, under certain circumstances,
a static charge can develop, igniting the
gasoline.
WHAT CAN HAPPEN
• A fire or explosion from gasoline can burn
you and others and cause property damage.
HOW TO AV
OID THE HAZARD
• Always place gasoline containers on the
ground away from your vehicle before
filling.
• 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.
• When practical, r
emove gas–power
ed
equipment from the truck or trailer and
refuel the equipment with its wheels on the
ground.
• 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.
• 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.
Filling the Fuel Tank
1. Park the machine on a level surface, disengage
the power take off (PTO), set the parking brake,
lower the attachment lift, and turn the ignition
key to “STOP” to stop the engine. Remove the

The
Safety Interlock System
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
• You are sitting on the seat
• The brake pedal is depressed
• The power take off (PTO) is OFF
The safety interlock system is designed to stop the
engine if:
• You rise from the seat when the brake pedal is
released
• You rise from the seat when the power take off
(PTO) is “ON”.
The safety interlock system is designed to stop the
power take off (PTO) if:
• You shift into reverse with the power take off
(PTO) engaged.
Operating–in–Reverse
An interlock feature is provided that prevents the
Power Take Off (PTO) from operating while the
tractor is traveling in reverse. If the unit is shifted into
reverse while the mower blade or other PTO driven
attachment is engaged, the PTO will stop.
If you need to mow while in reverse gear or use other
PTO driven attachments (such as a snowthrower or
tiller), this operating–in–reverse interlock feature may
be temporarily deactivated. Do not mow while
backing up unless it is absolutely necessary.
Operation
17
Before deactivating this feature, be sure there are no
children present on or near the property where you are
using the tractor, and that none are likely to appear
while you are mowing or operating an attachment. Be
extra observant after you have chosen to deactivate
the interlock feature because the sound of the tractor’s
engine might prevent you from being aware that a
child or a bystander has entered the area where you
are operating the tractor.
If you are certain that you can safely mow in reverse
or operate an attachment, deactivate the
operating–in–reverse interlock feature by turning the
“Key Choice” key (Fig. 15), located on the seat
bracket in front of and just below the seat, after
engaging the blade (PTO). A red light on the front
console (Fig. 16) will turn on as a reminder that the
operating–in–reverse interlock has been deactivated.
Once the interlock is deactivated it stays in this
mode––with your mower blade or PTO–driven
attachment operating whenever you back up–– and
the console light stays on until either the blade (PTO)
is disengaged, or the engine is turned off.
Note: Do not insert the “Key Choice” key
unless it is absolutely necessary to
mow in reverse or operate an
attachment. The “Key Choice” key
should also be removed from the unit
if it will be operated by someone other
than a responsible, experienced
operator. This will prevent the PTO
from operating when the tractor is
moving in reverse. Always remove
both the ignition and the “Key Choice”
keys and put them in a safe place out
of the reach of children when leaving
the unit unattended.
POTENTIAL HAZARD
• A child or bystander could be backed over
by a riding mower with its blade(s)
engaged.
WHAT CAN HAPPEN
• Blade contact will cause serious personal
injury or death.
HOW TO AV
OID THE HAZARD
• Do not mow in r
everse unless absolutely
necessary.
• Always look backward and down before
backing up.
• Use “Key Choice” key only if you are
certain no children or other bystanders will
appear in the mowing area.
•
Always r
emove both the ignition and “Key
Choice” keys and put them in a safe place
out of the reach of children or unauthorized
users when leaving the unit unattended.

Testing the Safety Interlock System
Test the safety interlock system each time before you
use the machine. Do not operate the machine if the
safety system is not functioning properly. If the safety
system does not operate as described below, have an
Authorized Service Dealer repair the safety system
immediately.
1. Fully depress the brake pedal. Pull the power
take–off (PTO) switch to ON. Now turn the
ignition key to START. The starter should not
crank.
2. Push the power take–off (PTO) switch to OFF
and release the brake pedal. Now turn the
ignition key to START; the starter should not
crank.
3. Fully depress the brake pedal and set the parking
brake. Push the PTO switch to OFF and rise
from the seat. Now turn the ignition key to
START. The starter should not crank.
4. Fully depress the brake pedal and set the parking
brake. Push the power take–off (PTO) switch to
OFF. Now start the engine. While the engine is
running, release the parking brake and rise
slightly from the seat; the engine should stop.
5. Fully depress the brake pedal, set the parking
brake, push the PTO switch to OFF and start the
engine. Pull the PTO switch to ON. Rise slightly
from the seat; the engine should stop.
6. With the parking brake released, turn the ignition
key to RUN without starting the engine. Pull the
PTO switch to ON. You should hear an audible
click indicating the PTO is activated and the
PTO light will illuminate. Move the foot pedal
to reverse. You should hear an audible click
indicating the PTO is deactivated and the PTO
light should turn off.
7. With the parking brake released, turn the ignition
switch to RUN without starting the engine. Pull
the PTO switch to ON. Turn the “Key Choice”
key and release. The Operating–in–Reverse
warning light should illuminate. Move the foot
pedal to reverse. The PTO and PTO light on the
dash should remain on. Push the PTO switch to
OFF. The PTO light and the
Operating–in–Reverse warning light should turn
off.
