Safety
Toro designed and tested this lawn mower to offer
reasonably safe service; however, failure to comply with
the following instructions may result in personal
injury.
Warning
Engine exhaust contains carbon monoxide, an
odorless, deadly poison that can kill you.
Do not run the engine indoors or in an enclosed
area.
To ensure maximum safety, best performance, and to
gain knowledge of the product, it is essential that you
and any other operator of the lawn mower read and
understand the contents of this manual before the
engine is ever started.
This is the safety alert symbol. It is used to alert
you to potential personal injury hazards. Obey all
safety messages that follow this symbol to avoid
possible injury or death.
Improperly using or maintaining this lawn mower can
result in injury. To reduce the potential for injury,
comply with these safety instructions.
• Never mow while people (especially children) or pets
are nearby. Stop the lawn mower if anyone enters the
area.
• Tragic accidents can occur if the operator is not alert
to the presence of children. Children are often
attracted to the lawn mower 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 a responsible adult.
• Be alert and turn the lawn mower off if children enter
the area.
• Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure vision.
• Keep in mind that the operator or user is responsible
for accidents or hazards occurring to other people or
their property.
• See the manufacturer’s instructions for proper
operation and installation of accessories. Use only the
accessories that are approved by the manufacturer.
Preparation
• Thoroughly inspect the area where you will use the
lawn mower, and remove all stones, sticks, wires,
bones, and other foreign objects.
• While mowing, always wear substantial footwear and
long trousers.
• Do not operate the lawn mower when barefoot or
wearing open sandals.
• Always wear safety goggles or safety glasses with side
shields when operating the lawn mower.
• Warning: Gasoline is highly flammable. Take the
following precautions:
General Lawn Mower Safety
This lawn mower is capable of amputating hands and feet
and of throwing objects. Failure to observe the following
safety instructions could result in serious injury or death.
Training
• Read this operator’s manual carefully. Be thoroughly
familiar with the controls and the proper use of the
lawn mower before starting it.
• Never allow children to operate the lawn mower.
Local regulations may restrict the age of the operator.
– Store fuel in containers specifically designed for
this purpose.
– Refuel outdoors only and do not smoke while
refuelling.
– Add fuel before starting the engine. Never remove
the cap of the fuel tank or add gasoline while the
engine is running or when the engine is hot.
– If gasoline is spilled, do not attempt to start the
engine. Move the lawn mower away from the area
of spillage to avoid creating any source of ignition
until the gasoline vapors have dissipated.
– Replace all fuel tank and container caps securely.
3
– If you must drain the fuel from the fuel tank, do it
outdoors.
• Never pick up or carry a lawn mower while the engine
is running.
• Replace faulty mufflers.
• Before using, always visually inspect the blades, blade
bolts, and cutter assembly for wear or damage.
Replace worn or damaged blades and bolts in sets to
preserve balance.
• On multibladed lawn mowers, use care as rotating one
blade can cause the other blades to rotate.
Operation
• Do not operate the engine in a confined space where
dangerous carbon monoxide fumes can collect.
• Mow only in daylight or in good artificial light.
• Always be sure of your footing on slopes.
• Walk; never run.
• Keep a firm hold on the handle.
• For wheeled rotary lawn mowers, mow across the face
of slopes, never up and down.
• Exercise extreme caution when changing the direction
on slopes.
• Do not mow excessively steep slopes.
• Use extreme caution when reversing or pulling the
lawn mower toward you.
• Before and while moving backward, look behind and
down for small children.
• Stop the blade(s) if you must tilt the lawn mower for
transportation when crossing surfaces other than grass
and when transporting the lawn mower to and from the
area to be mowed.
• Never operate the lawn mower with damaged or
missing guards or shields, or without safety devices
(such as deflectors and grass catchers) in place.
• Do not change the speed settings on the engine.
• Disengage all blade and drive clutches before starting
the engine.
• Stop the engine and disconnect the spark-plug wire:
– before clearing blockages or unclogging the chute;
– before checking, cleaning, or working on the lawn
mower;
– after striking a foreign object. Inspect the lawn
mower for damage and make repairs before starting
and operating the lawn mower; and
– if the lawn mower starts to vibrate abnormally
(check it immediately).
• Stop the engine:
– whenever you leave the lawn mower; and
– before refuelling.
• Reduce the throttle setting during engine run-out and,
if the engine has a shutoff valve, turn the fuel off after
mowing.
• Stop the blade(s) when crossing gravel drives, walks,
or roads.
• Shut the engine off and wait until the blade comes to a
complete stop before removing the grass catcher.
• Do not operate the lawn mower while under the
influence of alcohol or drugs.
• If the lawn mower should start to vibrate abnormally,
stop the engine and check immediately for the cause.
Vibration is generally a warning of trouble.
Slopes are a major factor related to slip and fall accidents
which can result in a severe injury. If you feel uneasy on a
slope, do not mow it.
• Watch for holes, ruts, or bumps. Tall grass can hide
obstacles.
• Do not mow near drop-offs, ditches, or embankments.
You could lose your footing or balance.
• Do not mow on wet grass. Reduced footing could
cause slipping.
• Start the engine carefully according to instructions and
with feet well away from the blade(s).
• Do not tilt the lawn mower when starting the engine,
unless you must tilt the lawn mower to start it. In this
case, do not tilt it more than absolutely necessary and
lift only the part which is away from the operator.
• Do not start the engine when standing in front of the
discharge chute.
• Do not put your hands or feet near or under rotating
parts. Keep clear of the discharge opening at all times.
4
Maintenance and Storage
• Keep all nuts, bolts (especially blade attachment
bolts), and screws tight to ensure that the lawn mower
is in safe working condition.
• Never store the lawn mower with gasoline in the tank
inside a building where fumes may reach an open
flame or spark.
• Allow the engine to cool before storing the lawn
mower in any enclosure.
• To reduce the fire hazard, keep the engine, muffler,
battery compartment, and gasoline storage area free of
grass, leaves, or excessive grease.
• Check the grass catcher frequently for wear or
deterioration.
• Replace worn or damaged parts.
• Use extra care when handling gasoline; gasoline
vapors are explosive.
• Never tamper with safety devices. Check their proper
operation regularly.
• Keep the lawn mower free of grass, leaves, or other
debris buildup. Clean up any oil or fuel that spills.

To add oil:
1. Move the lawn mower to a level surface.
2. Clean around the dipstick (Fig. 6).
3. Remove the dipstick by rotating the cap
counterclockwise and pulling it out.
4. Wipe the dipstick clean with a clean cloth.
5. Insert the dipstick into the filler neck (but do not
rotate the cap clockwise to secure it), then remove it.
6. Read the oil level on the dipstick (Fig. 6).
7. If the oil level reading is below the lower limit mark
on the dipstick, remove the dipstick and slowly pour
only enough oil into the filler hole to raise the oil level
to the upper limit mark on the dipstick (Fig. 6).
Important Do not overfill the crankcase with oil and
run the engine; engine damage will result. Drain the
excess oil until the oil level reaches the upper limit mark
on the dipstick.
8. Insert the dipstick into the filler neck and rotate the
cap clockwise until it is tight.
Before Starting
Filling the Crankcase with Oil
The engine crankcase can hold 22 ounces (0.65 liters) of
oil. Use only high-quality SAE 10W–30 weight detergent
oil that has the American Petroleum Institute (API)
service classification SH, SJ, or equivalent.
Before each use, ensure that the oil level is between the
lower limit and upper limit marks on the dipstick (Fig. 6).

3. Lower limit mark
Filling the Fuel Tank with
Gasoline
For best results, use clean, fresh, lead-free gasoline with
an octane rating of 87 or higher. To ensure freshness,
purchase only the quantity of gasoline that you expect to
use in 30 days. Using unleaded gasoline results in fewer
combustion deposits and longer engine life. You may use
leaded gasoline if unleaded gasoline is not available.
Important Do not add oil to the gasoline.
Important Do not use methanol, gasoline containing
methanol, gasohol containing more than 10% ethanol,
premium gasoline, or white gas. Using these fuels can
damage the engine’s fuel system.
Important Do not use gasoline that is more than 30
days old.
Note: When the crankcase is empty, pour about
three-fourths of the crankcase capacity of oil in the
crankcase, then follow the procedure in this section.
9
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.
1. Clean around the fuel tank cap (Fig. 7).
1

3
• Fill the fuel tank outdoors, in an open area, and
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
the gasoline to expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
• Store gasoline in an approved fuel container
and keep it out of the reach of children.
• Never buy more than a 30-day supply of
gasoline.
Danger
When fueling, under certain circumstances, a
static charge can develop, igniting the gasoline. A
fire or explosion from gasoline can burn you and
others and damage property.
• Always place gasoline containers on the ground
and 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 gasoline-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, not from a gasoline dispenser nozzle.
• If you must use a gasoline dispenser nozzle,
keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete.

3. Fill the fuel tank with unleaded gasoline to within 1/4
to 1/2 inch (6 to 13 mm) from the top of the tank. Do
not fill into the filler neck.
Note: The fuel tank capacity is 2.1 qt. (2.0 l).
Important Do not fill the tank more than 1/4 inch
(6 mm) from the top of the tank because the gasoline must
have room to expand.

Reviewing the Maintenance
Schedule
Review the Recommended Maintenance Schedule on
page 15. You may need to perform one or more additional
procedures before or soon after you begin operating the
lawn mower.
Use a fuel stabilizer/conditioner regularly during
operation and storage. A fuel stabilizer/conditioner cleans
the engine during operation and prevents gum-like varnish
deposits from forming in the engine during periods of
storage.
Important Do not use fuel additives other than a fuel
stabilizer/conditioner . Do not use fuel stabilizers with an
alcohol base such as ethanol, methanol, or isopropanol.

Operation
3. Move the throttle control to the Choke position
(Fig. 8).
Note: Determine the left and right sides of the machine
from the normal operating position.
Each time before you mow, ensure that the self-propel
drive and the control bar operate properly. When you
release the control bar, the engine and the blade should
stop within 3 seconds. If they do not, contact an
Authorized Service Dealer.
Caution
This machine produces sound levels in excess of
85dBA at the operator’s ear and can cause
hearing loss through extended periods of
exposure.
Wear hearing protection when operating this
machine.
Controls
The control bar, the throttle control, and the starter handle
are on the upper handle as shown in Figure 8.
2
Note: Do not use the choke when the engine is warm.
4. Hold the control bar to the handle (Fig. 8).
5. Pull the starter handle (Fig. 8) lightly until you feel
resistance, then pull it sharply. Allow the rope to return
to the handle slowly.
6. When the engine starts, move the throttle control to
the Fast position, and set the ground speed control as
desired.
Note: If the engine fails to start after three pulls, repeat
steps 4 through 6.
Stopping the Engine
Release the control bar. Both the engine and the blade
should stop within 3 seconds. If they do not, contact an
Authorized Service Dealer.
Note: Close the fuel valve by moving the lever to the left
if you will not be starting the engine soon afterward.
Using the Self-propel Drive
The lawn mower has three ground speeds. 1 is slow, 2 is
medium, and 3 is fast. The ground speed control is located

2. Run/Shift position
Note: Do not shift speeds while squeezing the control bar
against the handle in the Run/Drive position; this can
damage the transmission. Move the control bar to the
Run/Shift position (Fig. 11) when you change the ground
speed.
Note: You can vary the ground speed by increasing or
decreasing the distance between the control bar and the
handle. Lower the control bar to decrease the ground
speed when you are making a turn or if the lawn mower is
moving too fast for you. If you lower the control bar too
far, the lawn mower stops self-propelling. Squeeze the
control bar closer to the handle to increase the ground
speed. When you hold the control bar tight against the
handle, the lawn mower self-propels at the maximum
ground speed. Move the ground speed control to the
Neutral position when you use the lawn mower for
trimming or whenever you leave the lawn mower.

Warning
A worn grass bag could allow small stones and
other similar debris to be thrown in the operator’s
or bystander’s direction and result in serious
personal injury or death to the operator or
bystanders.
Check the grass bag frequently. If it is damaged,
install a new Toro replacement bag.
Cut the grass until the bag is full.
Important Do not overfill the bag.
Removing the Grass Bag
Danger
If the discharge door does not close completely,
the lawn mower could throw objects, causing
serious personal injury or death.
If you cannot close the door because the grass
clippings clog the discharge area, stop the engine
and gently move the discharge door handle back
and forth until you can close the door completely.
If you still cannot close the door, remove the
obstruction with a stick, not your hand.

Operating Tips
• Review the safety instructions and read this manual
carefully before operating the lawn mower.
• Clear the area of sticks, stones, wire, branches, and
other debris that the blade could hit and throw.
• Keep everyone, especially children and pets, away
from the area of operation.
• Avoid striking trees, walls, curbs, or other solid
objects. Never deliberately mow over any object.
• If the lawn mower strikes an object or starts to vibrate,
immediately stop the engine, disconnect the wire from
the spark plug, and examine the lawn mower for
damage.
• Maintain a sharp blade throughout the cutting season.
Periodically file down nicks on the blade.
• Replace the blade when necessary with an original
Toro replacement blade.
• Mow only dry grass or leaves. Wet grass and leaves
tend to clump on the yard and can cause the lawn
mower to plug or the engine to stall.
Cutting Grass
• Grass grows at different rates at different times of the
year. In the summer heat, it is best to cut grass at the
2-1/4-inch (5.7 cm), 2-3/4-inch (7.0 cm), or 3-1/4-inch
(8.3 cm) cutting height settings. Cut only about a third
of the grass blade at a time. Do not cut below the
2-1/4-inch (5.7 cm) setting unless the grass is sparse or
it is late fall when grass growth begins to slow down.
• When cutting grass over six inches (15 cm) tall, first
mow at the highest cutting height setting and walk
slower; then mow again at a lower setting for the best
lawn appearance. If the grass is too long and the leaves
clump on top of the lawn, the lawn mower may plug
and cause the engine to stall.
• Alternate the mowing direction. This helps disperse
the clippings over the lawn for even fertilization.
If the finished lawn appearance is unsatisfactory, try one
or more of the following:
• Sharpen the blade.
• Walk at a slower pace while mowing.
• Raise the cutting height on your lawn mower.
Warning
Wet grass or leaves can cause serious injury if you
slip and contact the blade.
Mow only in dry conditions.
• Clean the underside of the lawn mower housing after
each mowing. See Cleaning under the Housing on
page 16.
• Keep the engine in good running condition.
• Set the engine speed to the fastest position for the best
cutting results.
Warning
Operating a lawn mower with its engine running
at a speed greater than the factory setting can
cause the lawn mower to throw a part of the blade
or engine into the operator’s or bystander’s area
and result in serious personal injury or death.
• Do not change the engine speed setting.
• If you suspect the engine speed is faster than
normal, contact an Authorized Service Dealer.
• Cut the grass more frequently.
• Overlap cutting swaths instead of cutting a full swath
with each pass.
• Set the cutting height on the front wheels one notch
lower than the rear wheels. For example, set the front
wheels at 2-1/4 inches (5.7 cm) and the rear wheels at
2-3/4 inches (7.0 cm).
Cutting Leaves
• After cutting the lawn, ensure that half of the lawn
shows through the cut leaf cover. You may need to
make more than one pass over the leaves.
• For light leaf coverage, set all the wheels at the same
cutting height setting.
• If there are more than five inches (12.7 cm) of leaves
on the lawn, set the front cutting height one or two
notches higher than the rear cutting height. This makes
it easier to feed the leaves under the lawn mower
housing.
• Slow down your mowing speed if the lawn mower
does not cut the leaves finely enough.
• If you mow over oak leaves, you can add lime to the
grass in the spring to reduce the acidity of the oak
leaves.
• Clean the air filter frequently. Mulching stirs up more
clippings and dust which clogs the air filter and
reduces engine performance.
