Safe Operating Practices
The following instructions are from ANSI standard
B71.1—1998.
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.
• 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.
• 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.
• 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.
• Turn off blades when not mowing.
• Stop the engine before removing the grass catcher or
unclogging the chute.
• Mow 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.
3
Page 4
• Be alert, slow down and use caution when making
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 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.
Slope Operation
• Do not mow slopes greater than 15 degrees.
• 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.
• Do not mow slopes when grass is wet. Slippery
conditions reduce traction and could cause sliding and
loss of control.
• 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.
• Watch for ditches, holes, rocks, dips, and rises that
change the operating angle, as rough terrain could
overturn the machine.
• 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.
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.
A. Use only an approved container.

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 21.

Think Safety First
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.

Side Discharge
The mower has a hinged grass deflector that disperses
clippings to the side and down toward the turf.
Danger
Without the grass deflector, discharge cover, or
complete grass catcher assembly mounted in
place, you and others are exposed to blade contact
and thrown debris. Contact with rotating mower
blade(s) and thrown debris will cause injury or
death.
• Never remove the grass deflector from the
mower because the grass deflector routes
material down toward the turf. If the grass
deflector is ever damaged, replace it
immediately.
• Never put your hands or feet under the mower.
• Never try to clear discharge area or mower
blades unless you move the PTO to Off and
rotate the ignition key to Off. Also remove the
key and pull the wire off the spark plug(s).

Tips for Mowing Grass
Fast Throttle Setting
For best mowing and maximum air circulation, operate
the engine at Fast. Air is required to thoroughly cut grass
clippings, so do not set the height-of-cut so low as to
totally surround the mower by uncut grass. Always try to
have one side of the mower free from uncut grass, which
allows air to be drawn into the mower.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure that the
cutting height of the mower does not scalp any uneven
ground. However, the cutting height used in the past is
generally the best one to use. When cutting grass longer
than six inches tall, you may want to cut the lawn twice to
ensure an acceptable quality of cut.
Cut 1/3 of the Grass Blade
It is best to cut only about 1/3 of the grass blade. Cutting
more than that is not recommended unless grass is sparse,
or it is late fall when grass grows more slowly.
Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which enhances
decomposition and fertilization.
Long Grass
If the grass is ever allowed to grow slightly longer than
normal, or if it contains a high degree of moisture, raise
the cutting height higher than usual and cut the grass at
this setting. Then cut the grass again using the lower,
normal setting.
When Stopping
If the machine’s forward motion must be stopped while
mowing, a clump of grass clippings may drop onto your
lawn. To avoid this, move onto a previously cut area with
the blades engaged.
Keep the Underside of the Mower Clean
Clean clippings and dirt from the underside of the mower
after each use. If grass and dirt build up inside the mower,
cutting quality will eventually become unsatisfactory.
Blade Maintenance
Maintain a sharp blade throughout the cutting season
because a sharp blade cuts cleanly without tearing or
shredding the grass blades. Tearing and shredding turns
grass brown at the edges, which slows growth and
increases the chance of disease. Check the cutter blades
daily for sharpness, and for any wear or damage. File
down any nicks and sharpen the blades as necessary. If a
blade is damaged or worn, replace it immediately with a
genuine Toro replacement blade.
Mow at Correct Intervals
Normally, mow every four days. But remember, grass
grows at different rates at different times. So to maintain
the same cutting height, which is a good practice, mow
more often in early spring. As the grass growth rate slows
in mid summer, mow less frequently. If you cannot mow
for an extended period, first mow at a high cutting height;
then mow again two days later at a lower height setting.
Cutting Speed
To improve cut quality, use a slower ground speed.
Avoid Cutting Too Low
If the cutting width of the mower is wider than the mower
you previously used, raise the cutting height to ensure that
uneven turf is not cut too short.

correctly.
2. Tighten the spark plug to 30 ft.-lb. (41 N⋅m).
3. Push the wire onto the spark plug (Fig. 22).
Cutting Blades
Maintain sharp blades throughout the cutting season
because sharp blades cut cleanly without tearing or
shredding the grass blades. Tearing and shredding turns
grass brown at the edges, which slows growth and
increases the chance of disease.
Check the cutter blades daily for sharpness, and for any
wear or damage. File down any nicks and sharpen the
blades as necessary. If a blade is damaged or worn,
replace it immediately with a genuine Toro replacement
blade. For convenient sharpening and replacement, you
may want to keep extra blades on hand.
