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 symbol, which means CAUTION,
WARNING, or DANGER-"personal safety
instruction." Failure to comply with the instruction
may result in personal injury or death.
• Never leave a running machine unattended. Always
turn off blades, set paring brake, stop engine, and
remove key before dismounting.
• Turn off blades when not mowing. Stop the engine
and wait 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.
Safe Operating Practices
The following instructions are from ANSI standard
B71.1-2003.
This product is capable of amputating hands and
feet and throwing objects. Always follow all safety
instructions to avoid serious injury or death.
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 dear 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 awone enters the area.
• Never carry passengers.
• Do not mow in reverse unless absolutely necessar>
Always look down and behind before and while
bac_ng up.
• Be aware of the mower discharge direction and do
not point it at awone. Avoid discharging material
against a wall or obstruction. Material m W ricochet
back toward the operator. Stop the blade(s) when
crossing gravel surfaces.
• Do not operate the machine without deflector,
discharge cover or entire grass collection system in
place and wor_ng.
• Be alert, slow down and use caution when maMng
turns. Look behind and to the side before changing
directions.
• Use extra care when loading or unloading the
machine into a trailer or truck.
Always wear eye protection when operating the
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 injur>
• Always follow the recommendations for wheel
weights or counterweights.
• Lightning can cause severe injury or death. If
lightning is seen or thunder is heard in the area, do
not operate the machine; seek shelter.
Slope Operation
Slopes are a major factor related to loss of control and
tip-over accidents, which can result in severe injury or
death. Operation on all slopes requires extra caution. If
you cannot back up the slope or if you feel uneasy on it,
do not mow it.
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 wheel motors engaged when going
down slopes.
• Reduce speed and use extreme caution on slopes.
• Do not make sudden turns or rapid speed changes.

obstacles.
Avoidsuddenstartswhenmovdnguphillbecause
themowermaytip 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 brak:ing
and steering.
Ahvays avoid sudden starting or stopping on a
slope. If tires lose traction, disengage the blades and
proceed slovdy off the slope.
Use extreme care with grass catchers or other
attachments. These can change the stabiliD- of the
machine and cause loss of control.
Do not try to stabilize the machine by putting your
foot on the ground.
Towing
A hitch -kitis available for this machine and can be
obtained by contacting an Authorized Toro Dealer.
Do not tow without first installing this manufacturer
approved hitch. The follovdng guidelines apply when
towing with the approved hitch -kitinstalled.
• Tow only vdth a machine that has a hitch designed
for towing. Do not attach towed equipment except
at the hitch point.
• Follow the manufacturer's recommendation for
weight limits for towed equipment and towing on
slopes.
• Never allow children or others in or on towed
equipment.
• On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
• Travel slowly and allow extra distance to stop.
Do not mow near drop-offs, ditches, steep banks
or water. Wheels dropping over edges can cause
rollovers, which may result in serious injur B death
or drowning.
Use a walk behind mower and/or a hand trimmer
near drop-offs, ditches, steep banks or water.
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 activi_: Never assume that
children vdll remain where you last saw them.
Keep children out of the mowing area and under
the watchful care of another responsible adult, not
the operator.
Be alert and turn the machine off if children enter
the area.
Before and while bac "tdng 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 vdth
safe machine operation.
Children who have been given rides in the past may
suddenly appear in the movdng 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
Safe Handling of Gasoline:
To avoid personal injury or property damage, use extra
care when handling gasoline and other fuels. They are
flammable and the 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.
• 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 vdth a plastic liner. Ahvays 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 vdth a portable
container, rather than from a gasoline dispenser
nozzle.
• Keep the nozzle in contact vdth 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.
• If fuel is spilled on clothing, change clothing
immediatel3:
• Never overfill the fuel tank. Replace gas cap and

Motion Control Levers and Park
Position
The motion control levers are speed sensitive controls of
independent wheel motors. Moving a lever 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. Move the control levers outward from
the center to the park position and exit the machine
(Figure 16). Always position the motion control levers
into the park position when you stop the machine or
leave it unattended.
Fuel Gauge
The fuel window located below the operator position
can be used to veri_; the level of gasoline in the tank
(Figure 7).
Ignition Switch
The ignition switch has three positions, Off, Run and
Start. The key will turn to Start and move back to
Run upon release. Turning the key to the Off position
will stop the engine; however, always remove the key
when leaving the machine to prevent someone from
accidentally starting the engine (Figure 6).
Throttle Control
The throttle controls the engine speed and it has a
continuous variable setting from Slow to Fast (Figure 6).
Choke Control
Pull up on the Choke control until it stops to choke the
engine (Figure 6). Push down on the Choke control for
normal engine operation
Throttle/Choke Control
The throttle and choke is combined into one control
lever. The throttle controls the engine speed and it has a
continuous variable setting from Slow to Fast. Engage
the choke by moving the lever past the Fast setting until
it stops (Figure 6).

Height-of-Cut Lever
The height of cut lever allows the operator to lower
and raise the deck from the seated position. When the
lever is moved up, toward the operator the deck is raised
from the ground and when moved down, away from the
operator it is lowered toward the ground. Only adjust the
height of cut while machine is not moving (Figure 19).

Think Safety First
Please carefully read all of the safe b- instructions and
decals in the safety section. Knowing this information
could help you, your famil3; pets or bystanders avoid
injur3=
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.
A loss of traction is a loss of steering control.
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.
• When mowing slopes, gradually work from
lower to higher areas on the incline.
• Avoid sudden turns or rapid speed changes.

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 percent ethanol because the fuel system
could be damaged. Do not mix oil with gasoline.
• Turn up, into an incline when changing
directions on slopes. Turning down the slope
reduces traction.
Attachments change the handling
characteristics of the machine. Use
extra caution when using attachments with the
machine.
14

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.
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.
Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the body of the
tank is full but fuel does not fill the neck of
the tank. 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.
Do not operate without entire exhaust system
in place and in proper working condition.
In certain conditions during fueling, static
electricity can be released causing a spark which
can ignite the gasoline vapors. A fire or explosion
from gasoline can burn you and others and can
damage property.
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.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to
provide the following benefits:
• Keeps gasoline flesh during storage of 30 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.
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.
Gasoline/Alcohol blends
Gasohol (up to 10 percent ethJ alcohol, 90 percent
unleaded gasoline by volume) is approved for fuel use
by the engine manufacturer. Other gasoline/alcohol
blends, such as E85, are not approved.
Gasoline/Ether blends
Methyl Tertiary Bu@ Ether (MTBE) and unleaded
gasoline blends (up to a maximum of 15 percent MTBE
by volume) are approved for fuel use by the engine
manufacturer. Other gasoline/ether blends are not
approved.
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.
Fuel Gauge
Use the fuel window below the operator to veri_- the
level of gasoline before filling the tank (Figure 9).
