Safety

Improperly using or maintaining this lawn mower can
result in injury. To reduce the potential for injury,
comply with these safety instructions.

Toro designed and tested this lawn mower for to offer
reasonably safe service; however, failure to comply with the

following instructions may result in personal injury.

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.

• Never allow adults unfamiliar with these instructions to

operate the lawn mower.

• 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.

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. Pay particular attention to the
safety alert symbol which means caution, warning,

or danger — “personal safety instruction.” Read and
understand the instruction because it has to do with
safety. Failure to comply with the instruction may result
in personal injury.

General Lawn Mower Safety

The following instructions have been adapted from the
ANSI/OPEI standard B71.1—1998 and ISO standard
5395:1990(E). Information or terminology specific to Toro
lawn mowers is enclosed in parenthesis.

• 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:
– Store fuel in containers specifically designed for this

purpose.

3

– Refuel outdoors only and do not smoke while

refuelling.

• Disengage all blade and drive clutches before starting

the engine.

– 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.
– If you must drain the fuel from the fuel tank, do it

outdoors.

• 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.

• 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.

• Never pick up or carry a lawn mower while the engine

is running.

• 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.

4

• Do not mow on wet grass. Reduced footing could cause

slipping.

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.

• Stop and inspect the lawn mower if you strike an object.

Repair the lawn mower, if necessary, before starting the
engine.

• Grass catcher components are subject to wear, damage,

and deterioration, which could expose moving parts or
allow objects to be thrown. Frequently check the
components and replace them with the manufacturer’s
recommended parts when necessary.

• Lawn mower blades are sharp and can cut. Wrap the

blade(s) or wear gloves, and use extra caution when
servicing them.

• Do not change the speed settings on the engine.

• If you must drain the fuel from the fuel tank, do it

outdoors.

• To ensure the best performance and safety, purchase

only genuine Toro replacement parts and accessories.

• Maintain or replace safety and instruction decals when

necessary.

Before Starting

Filling the Crankcase with Oil

The crankcase can hold 22 ounces (0.65 liters) of oil. Use
only high-quality, SAE 30 or SAE 10W30 weight detergent
oil that has the American Petroleum Institute (API) service
classification SF, SG, SH, or SJ.

Before each use, ensure that the oil level is between the
Add and the Full marks on the dipstick (Fig. 6).

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. Fully insert the dipstick into the filler neck, then remove

it.

Note: To ensure an accurate oil level reading, you must
fully install the dipstick.

6. Read the oil level on the dipstick (Fig. 6).

7. If the oil level reading is below the Add mark on the

dipstick, slowly pour only enough oil into the filler hole
to raise the oil level to the Full mark on the dipstick.

Important Do not overfill the crankcase with oil and

run the engine; engine damage will result. Drain the excess
oil until the oil level on the dipstick reads Full.

8. Insert the dipstick into the filler neck and rotate the cap

clockwise until it is tight.

Filling the Fuel Tank with
Gasoline

For best results, use clean, fresh, lead-free gasoline,
including oxygenated or reformulated 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. Unleaded gasoline burns cleaner, extends engine life,
and promotes good starting. You may use leaded gasoline if
unleaded gasoline is not available.

Important Do not add oil to the gasoline.

8

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.

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.

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, 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.

• 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 round.

• 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.

Use a fuel stabilizer/conditioner regularly during operation
and storage. A 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.

1. Clean around the fuel tank cap (Fig. 7).

1626

Figure 7

1. Fuel tank cap

2. Remove the cap from the tank.

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.

4. Install the fuel tank cap and wipe up any spilled

gasoline.

Reviewing the Maintenance
Schedule

Note: Do not use the primer to start a warm engine after a
brief shutdown. However, cool weather may require you to
prime the engine again.

Review the Recommended Maintenance Schedule on
page 14. You may need to perform one or more additional
procedures before or soon after you begin operating the
lawn mower.

Operation

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
(self-propel model only) and the blade control bail operate
properly. When you release the blade control bail, the
engine and the self-propel drive should stop. If they do not,
contact an Authorized Service Dealer.

Controls

The starter handle and the blade control bail are on the
upper handle as shown in Figure 8.

Figure 11

Note: If the battery is too low to start the engine, start
the engine manually.

Note: If the engine fails to start after 3 attempts, repeat
steps 2 through 4.

Stopping the Engine

Release the blade control bail. Both the engine and the
blade should stop. If they do not stop properly, contact your
Authorized Service Dealer.

Using the Self-propel Drive

To operate the self-propel drive, simply walk forward with
your hands on the upper handle and your elbows at your
sides, and the lawn mower will automatically keep pace
with you. The faster you walk, the farther the handle will
slide and the faster the lawn mower will propel (Fig. 12).

10

m–4206

Figure 12

To slow down the drive, simply slow your walking speed;
to stop the drive, stop walking (Fig. 12).

Note: If, when backing up after self-propelling, the lawn
mower does not roll backward freely, nudge the lawn
mower forward about an inch without engaging the
self-propel drive, then pull the lawn mower backward.

Adjusting the Cutting Height

2. Move the lawn mower into the grass; stop moving the

lawn mower when the SmartWheel design on one of the
rear wheels is upright (Fig. 13).

3. Use the SmartWheel design to compare the tips of the

grass blades to the letters on the wheel. The letter on the
SmartWheel that matches the tips of the grass blades is
the proper cutting height.

4. Press down on the red button and hold the cutting

height adjustment handle to move the cutting height up
or down (Fig. 14).

1

2

The SmartWheel has 2 cutting scales: Sparse/Normal and
Lush—to ensure the best cutting height setting in any

mowing condition (Fig. 13). Use the Sparse/Normal scale
during the warm summer season for the majority of your
mowing. The Lush scale is for thick, moist, and succulent
grass that grows most often in the spring.

Toro recommends the following:

• Cut the grass at the D, E, or F settings or keep the grass
between 2 to 3 inches (5.1 to 7.6 cm) high.

3. Pointer

• Do not cut below the D setting unless the grass is sparse

or it is late fall when grass growth begins to slow down.
When you cut long grass, use a higher cutting height
setting and walk slower; then cut the grass again at a
normal setting. Mowing the grass when it is too long
can plug the lawn mower and cause the engine to stall.

Note: The SmartWheel calculates the proper setting to
ensure that you cut no more than a third of the grass blade.

1. Stop the engine and wait for all moving parts to stop.

Using the Grass Bag

Occasionally, you may want to use the grass bag for
bagging lush grass or collecting leaves.

Installing the Grass Bag

1. Stop the engine and wait for all moving parts to stop.

2. Open the rear door (Fig. 1).

3. Hold the spring-loaded rear door up to prevent it from

closing.

Danger

If the rear door does not close completely, the lawn
mower could throw objects, causing serious
personal injury or death.

If you cannot close the rear door because the grass
clippings clog the discharge area, stop the engine,
wait for all moving parts to stop, and remove the
grass clippings (with a stick, not your hand) until
the rear door closes completely.

4. Remove the recycler plug.

5. Hang the grass bag frame pins onto the deck hooks as

Rear Discharge

Occasionally, you may need to cut the lawn without the
grass bag or the recycler plug when the grass is too long for
bagging.

To use the rear discharge feature, remove the recycler plug
or the grass bag (refer to Removing the Grass Bag on
page 12), and close the rear door.

Danger

Warning

If the rear door does not close completely, the lawn
mower could throw objects, causing serious
personal injury or death.

If you cannot close the rear door because the grass
clippings clog the discharge area, stop the engine,
wait for all moving parts to stop, and remove the
grass clippings (with a stick, not your hand) until
the rear door closes completely.

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.

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.

• Clean the air filter frequently. Recycling stirs up more
clippings and dust which clogs the air filter and reduces
engine performance.

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 C,
D, or E cutting height settings. Cut only about a third of
the grass blade at a time. Do not cut below the C setting
unless the grass is sparse or it is late fall when grass
growth begins to slow down.

• When cutting grass over 6 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.

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 deck after each

mowing. See Cleaning the Underside of the Lawn
Mower Housing on page 15.

• Keep the engine in good running condition.

• Set the engine speed to the fastest position for the best

cutting results.

• Raise the cutting height on your lawn mower.

• 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 the C setting and the rear wheels at the D
setting.

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.

13

• For light leaf coverage, set all the wheels at the same

cutting height setting.

• Slow down your mowing speed if the lawn mower does

not cut the leaves finely enough.

• If there are more than 5 inches (12.7 cm) of leaves on

the lawn, set the front cutting height one or 2 notches
higher than the rear cutting height. This makes it easier
to feed the leaves under the lawn mower deck.

• If you mow over oak leaves, you can add lime to the

grass in the spring to reduce the acidity of the oak
leaves.

Maintenance

Note: Determine the left and right sides of the machine from the normal operating position.
