Important calls attention to special mechanical
information and Note: emphasizes general information
worthy of special attention.
General Operation
• Read, understand, and follow all instructions in the
operator’s manual and on the machine before starting.
• Do not place hands or feet near rotating parts or under
the machine. Keep clear of the discharge opening at all
times.
• Allow only responsible adults who are familiar with the
instructions to operate the machine.
• Clear the area of objects such as rocks, toys, wire, etc.,
which could be picked up and thrown by the blade.
• Be sure the area is clear of other people before mowing.
Stop the machine if anyone enters the area.
• Never carry passengers.
• Do not mow in reverse. Always look down and behind
before and while backing up.
• Be aware of the mower discharge direction and do not
point it at anyone. Avoid discharging material against a
wall or obstruction. Material may ricochet back toward
the operator. Stop the blade(s) when crossing gravel
surfaces.
• Do not operate the mower without either the entire
grass catcher or the guard in place.
• Be alert, slow down and use caution when making
turns. Look behind and to the side before changing
directions.
• Never leave a running machine unattended. Always turn
off blades, set parking brake, stop engine, and remove
key before dismounting.
Safety
This machine meets or exceeds the B71.1–2003
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
CAUTION, WARNING, or DANGER—“personal
safety instruction.” Failure to comply with the
instruction may result in personal injury or death.
symbol, which means
• Turn off blades when not mowing. Stop the engine and
what for all parts to come to a complete stop before
cleaning the machine, removing the grass catcher or
unclogging the discharge chute.
• Operate the machine only in daylight or good artificial
light.
• Do not operate the machine while under the influence
of alcohol or drugs.
• Watch for traffic when operating near or crossing
roadways.
• Use extra care when loading or unloading the machine
into a trailer or truck.
3
• Always wear safety goggles or safety glasses with side
shields when operating 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 riding mower safely
enough to protect themselves and others from serious
.
injury
• Always follow the recommendations for wheel weights
or counterweights.
Slope Operation
• Do not mow slopes greater than 15 degrees.
• Watch for ditches, holes, rocks, dips, and rises that
change the operating angle, as rough terrain could
overturn the machine.
• Choose a low ground speed so you will not have to stop
while operating on a slope.
• Do not mow slopes when grass is wet. Slippery
conditions reduce traction and could cause sliding and
loss of control.
• Always keep the machine in gear when going down
slopes. Do not shift to neutral and coast downhill.
• Reduce speed and use extreme caution on slopes.
• Do not make sudden turns or rapid speed changes.
• Use a walk behind mower and/or a hand trimmer near
drop–offs, ditches, steep banks or water.
• Remove or mark obstacles such as rocks, tree limbs,
etc. from the mowing area. Tall grass can hide
obstacles.
• 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.
• Always avoid sudden starting or stopping on a slope. If
tires lose traction, disengage the blades and proceed
slowly off the slope.
• Use extreme care with grass catchers or other
attachments. These can change the stability of the
machine and cause loss of control.
• Do not try to stabilize the machine by putting your foot
on the ground.
• Do not mow near drop–offs, ditches, steep banks or
water. Wheels dropping over edges can cause rollovers,
which may result in serious injury, death or drowning.
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.
• Keep children out of the mowing area and under the
watchful care of another responsible adult.
• Be alert and turn the machine off if children enter the
area.
• Before and while backing or changing direction, look
behind, down, and side–to–side for small children.
• Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere with
safe machine operation.
• Children who have been given rides in the past may
suddenly appear in the mowing area for another ride
and be run over or backed over by the mower.
• Never allow children to operate the machine.
• Use extra care when approaching blind corners, shrubs,
trees, the end of a fence or other objects that may
obscure vision.
Service
• Use extra care when handling gasoline and other fuels.
They are flammable and vapors are explosive.
• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
• Use only an approved container.
• Never remove the gas cap or add fuel when the
engine is running. Allow the 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 near a water
heater or furnace.
• Never fill containers inside a vehicle or on a truck or
trailer with a plastic liner. Always place containers
on the ground away from your vehicle before filling.
• Remove gas-powered equipment from the truck or
trailer and refuel it on the ground. If this is not
possible, then refuel such equipment with a portable
container, rather than from a gasoline dispenser
nozzle.
• Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times until the
fueling is complete. Do not use a nozzle lock-open
device.
4
• If fuel is spilled on clothing, change clothing

contact with skin, eyes, and clothing. Protect your face,
eyes, and clothing when working with a battery.
• Battery gases can explode. Keep cigarettes, sparks and
flames away from battery.
• Use only Toro approved attachments. Warranty may be
voided if used with unapproved attachments.
• If loading the machine onto a trailer or truck, use a
single, full-width ramp only. The ramp angle should not
exceed 15 degrees.
• Mower blades are sharp and can cut. Wrap the blade(s)
or wear gloves, and use extra caution when servicing
them.
• Check for proper brake operation frequently. Adjust and
service as required.
• Maintain or replace safety and instruction decals as
necessary.
• Use only genuine Toro replacement parts to ensure that
original standards are maintained.

Gasoline and Oil
Recommended Gasoline
Use UNLEADED Regular Gasoline suitable for automotive
use (87 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.
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
• Never fill the fuel tank inside an enclosed trailer.
• 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 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.
• 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, remove gas–powered
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.
Warning
Gasoline is harmful or fatal if swallowed.
Long–term exposure to vapors can cause serious
injury and illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
conditioner opening.
• Keep gas away from eyes and skin.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
• Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank
be drained.
• Cleans the engine while it runs
• Eliminates gum-like varnish buildup in the fuel system,
which causes hard starting
Important Do not use fuel additives containing
methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner to the
gas.
Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline. To minimize the chance of
varnish deposits in the fuel system, use fuel stabilizer at all
times.
Filling the Fuel Tank
1. Shut the engine off and set the parking brake.
2. Clean around the fuel tank cap and remove the cap. Add
unleaded regular gasoline to the fuel tank until the level
is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the
filler neck. This space in the tank allows gasoline to
expand. Do not fill the fuel tank completely full.
3. Install the fuel tank cap securely. Wipe up any gasoline
that may have spilled.
Checking the Engine Oil Level
Before you start the engine and use the machine, check the
oil level in the engine crankcase; refer to Checking the Oil
Level, page 20.

Please carefully read all of the safety instructions and
decals in the safety section. Knowing this information
could help you, your family, pets or bystanders avoid
injury.
Danger
Mowing on wet grass or steep slopes can cause
sliding and loss of control.
Wheels dropping over edges can cause rollovers,
which may result in serious injury, death or
drowning.
To avoid loss of control and possibility of rollover:
• Do not mow near drop–offs or near water.
• Do not mow slopes greater than 15 degrees.
• Reduce speed and use extreme caution on slopes.
• Avoid sudden turns or rapid speed changes.
