operator’s manual and on the machine before starting.
Serial No.
• 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.
This manual identifies potential hazards and has special
safety messages that help you and others avoid personal
injury and even death. Danger, Warning, and Caution are
signal words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
• Be sure the area is clear of other people before mowing.
Stop the machine if anyone enters the area.
• Never carry passengers.
Danger signals an extreme hazard that will cause serious
injury or death if you do not follow the recommended
precautions.
• Do not mow in reverse unless absolutely necessary.
Always look down and behind before and while
backing.
Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.
• 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.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
• Slow down before turning.
This manual uses two other words to highlight information.
Important calls attention to special mechanical
information and Note: emphasizes general information
worthy of special attention.
• 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
• Use extra care when loading or unloading the machine
into a trailer or truck.
• Keep children out of the mowing area and under the
watchful care of another responsible adult.
• Always wear safety goggles or safety glasses with side
shields when operating mower.
• Be alert and turn the machine off if children enter the
area.
• 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.
• Before and while backing, look behind and down 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.
• Never allow children to operate the machine.
Slope Operation
• Use extra care when approaching blind corners, shrubs,
trees, the end of a fence or other objects that may
obscure vision.
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.
Service
• Mow up and down slopes, not across.
• Use extra care when handling gasoline and other fuels.
They are flammable and vapors are explosive.
• Remove obstacles such as rocks, tree limbs, etc.
A. Use only an approved container.
• Watch for holes, ruts or bumps. Uneven terrain could
overturn the machine. Tall grass can hide obstacles.
B. Never remove the gas cap or add fuel when the
engine is running. Allow the engine to cool before
refueling. Do not smoke.
• Use slow speed. Choose a low gear so that you will not
have to stop or shift while on the slope.
C. Never refuel the machine indoors.
• Follow Toro’s recommendations for wheel weight or
counterweights to improve stability.
D. Never store the machine or fuel container inside
where there is an open flame, such as near a water
heater or furnace.
• Use extra care with grass catchers or other attachments.
These can change the stability of the machine.
• Never run a machine inside a closed area.
• Keep all movement on slopes slow and gradual. Do not
make sudden changes in speed or direction.
• Keep nuts and bolts tight, especially the blade
attachment bolts. Keep equipment in good condition.
• Avoid starting or stopping on a slope. If tires lose
traction, disengage the blades and proceed slowly
straight down the slope.
• Never tamper with safety devices. Check their proper
operation regularly.
• Do not turn on slopes unless necessary, and then, turn
slowly and gradually downhill, if possible.
• Keep the machine free of grass, leaves, or other debris
build-up. Clean up oil or fuel spillage. Allow the
machine to cool before storing.
• 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.
• Stop and inspect the equipment if you strike an object.
Repair, if necessary, before restarting.
• Do not mow on wet grass. Reduced traction could cause
sliding.
• Grass catcher components are subject to wear, damage
and deterioration, which could expose moving parts or
allow objects to be thrown. Frequently check
components and replace with manufacturer’s
recommended parts, when necessary.
• Do not try to stabilize the machine by putting your foot
on the ground.
• Do not use a grass catcher on steep slopes.
• Mower blades are sharp and can cut. Wrap the blade(s)
or wear gloves, and use extra caution when servicing
them.
Children
• Use only genuine Toro replacement parts to ensure that
original standards are maintained.
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.

Toro Riding Mower Safety
The following list contains safety information specific to
Toro products or other safety information that you must
know that is not included in the ANSI standards.
Warning
Engine exhaust contains carbon monoxide, which
is an odorless, deadly poison that can kill you.
Do not run engine indoors or in an enclosed area.
• Stop the engine, disconnect spark plug wire(s) and
remove key before performing any service, repairs,
maintenance or adjustments.
• Slow down before turning. Sharp turns on any terrain
may cause loss of control.
• Never leave a running machine unattended. Always turn
off blades, set parking brake, stop engine, and remove
the ignition key before dismounting.
• Keep hands, feet, hair, and loose clothing away from
attachment discharge area, underside of mower and any
moving parts while engine is running.
• Do not touch equipment or attachment parts which may
be hot from operation. Allow to cool before attempting
to maintain, adjust or service.
• Battery acid is poisonous and can cause burns. Avoid
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 genuine replacement parts to ensure that
original standards are maintained.
• Use only Toro approved attachments. Warranty may be
voided if used with unapproved attachments.
• Do not mow across slopes exceeding 5 degrees.
• Do not mow down slopes exceeding 15 degrees.
• Do not mow up slopes exceeding 10 degrees.
• If a steep slope must be ascended, back up the hill, and
drive forward down the hill, keeping the machine in
gear.
• Avoid turning on slopes. If you must turn, turn slowly
and gradually downhill, if possible.
• Do not use a grass catcher on steep slopes. Heavy grass
bags could cause loss of control or overturn the
machine.
• If loading the machine onto a trailer or truck, use a
single, full-width ramp only. The ramp angle should not
exceed 15 degrees.

Gasoline and Oil
Recommended Gasoline
Warning
Use UNLEADED Regular Gasoline suitable for automotive
use (87 pump octane minimum). Leaded regular gasoline
may be used if unleaded regular is not available.
Gasoline is harmful or fatal if swallowed.
Long–term exposure to vapors can cause serious
injury and illness.
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.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
conditioner opening.
• Keep gas away from eyes and skin.
Danger
Using Stabilizer/Conditioner
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.
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.
• 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 in. (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.
• 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 in. (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 24.

Pushing the Machine by Hand
Side Discharge
Important Always push the machine by hand. Never
tow the machine because damage may occur.
The mower has a hinged grass deflector that disperses
clippings to the side and down toward the turf.
Danger
To Push the Machine
1. Disengage the PTO, stop the engine, and remove the
key.
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.
2. Pull the two bypass levers up and push them until the
washer on the rod passes through the slot. Push the
levers down to lock them in place (Fig. 14).
3. Disengage the parking brake to push the machine.
• Never remove the grass deflector from the
2
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
Figure 14
1. Position for pushing the
machine
2. Position for operating the
machine
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.
To Operate the Machine
Pull each bypass lever up and pull them completely out.
Push the levers down (Fig. 14).
Note: The machine will not drive unless the bypass levers
are pulled out.
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.
18
Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which enhances
decomposition and fertilization.
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.
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.

Remove the key from the ignition and disconnect the wire from the spark plug(s) before you do
any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.
20
Cutting Blades
Checking for Bent 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.
1. Stop the engine, set the parking brake, remove the key,
and disconnect the spark plug wire(s) from the spark
plug(s).
2. Rotate the blades until the ends face forward and
backward (Fig. 16). Measure from a level surface to the
cutting edge of the blades (Fig. 17). Note this
dimension.
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.

Inspecting the Blades
3. Rotate the opposite ends of the blades forward. Measure
from a level surface to the cutting edge of the blades at
the same position as in step 2 above. The difference
between the dimensions obtained in steps 2 and 3 must
not exceed 1/8 in. (3 mm). If this dimension exceeds
1/8 in. (3 mm), the blade is bent and must be replaced;
refer to Removing the Blades and Installing the Blades,
page 22.
1. Inspect the cutting edges (Fig. 15). If the edges are not
sharp or have nicks, remove and sharpen the blades;
refer to Sharpening the Blades, page 22.
2. Inspect the blades, especially the curved area (Fig. 15).
If you notice any damage, wear, or a slot forming in this
area (item 3 in Fig. 15), immediately install a new
blade.
Warning
