Safety
Toro designed this lawn mower for cutting and mulching grass, or, when equipped with a grass bag, for catching cut grass. Any use for purposes other than these could prove dangerous to the operator or to bystanders.
Note: This engine is not equipped with a spark
arrester muffler. Operating this mower on any forest-covered, brush-covered, or unimproved grass-covered land without an approved spark arrester muffler may violate your state law.
POTENTIAL HAZARD
Engine exhaust contains carbon monoxide,
which is an odorless, deadly poison.
WHAT CAN HAPPEN
Carbon monoxide can kill you and is also
known to the State of California to cause birth defects.
HOW TO AV
Do not run engine indoors or in an enclosed
area.
OID THE HAZARD
Training
Read the instructions carefully. Be familiar with
the controls and the proper use of the equipment before starting.
See manufacturer’s instructions for proper
operation and installation of accessories. Only use accessories approved by the manufacturer.

pets are nearby. Stop 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 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 mower off if children enter the
area.
Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure vision.
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 motor 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 instruction may result in personal injury.
General
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.
This cutting machine is capable of amputating hands and feet and throwing objects. Failure to observe the following safety instructions could result in serious injury or death.
Lawn Mower Safety
Keep in mind that the operator or user is
responsible for accidents or hazards occurring to other people or their property.
Preparation
While mowing, always wear substantial footwear
and long trousers.
Do not operate the equipment when barefoot or
wearing open sandals.
Always wear safety goggles or safety glasses with
side shields when operating mower.
Thoroughly inspect the area where the equipment
is to be used and remove all stones, sticks, wires, bones, and other foreign objects.
Warning: Gasoline is highly flammable. Take
the following precautions:
Store fuel in containers specifically
designed for this purpose.
2
Page 5
Safety
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 but move the machine away from the area of spillage and avoid creating any source of ignition until gasoline vapors have dissipated.
Replace all fuel tank and container caps
securely.
If the fuel tank has to be drained, do this
outdoors.
Replace faulty mufflers.
Before using, always visually inspect to see that
the blades, blade bolts, and cutter assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance.
On multibladed machines, take care as rotating
one blade can cause other blades to rotate.
Stop the blade(s) if the mower has to be tilted for
transportation when crossing surfaces other than grass and when transporting the mower to and from the area to be mowed.
Never operate the mower with damaged or
missing guards or shields, or without safety devices; for example, deflectors and/or grass catchers in place.
Do not change the engine governor settings or
overspeed the engine.
Disengage all blade and drive clutches before
starting the engine.
Start the engine or switch on the motor carefully
according to instructions and with feet well away from the blade(s).
Do not tilt when starting the engine or switching
on the motor, unless the mower has to be tilted for starting. 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 hands or feet near or under rotating
parts. Keep clear of the discharge opening at all times.
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 machines, mow across the face
of slopes, never up and down.
Exercise extreme caution when changing direction
on slopes.
Do not mow excessively steep slopes.
Use extreme caution when reversing or pulling the
mower towards you.
Before and while moving backwards, look behind
and down for small children.
Never pick up or carry a mower while the engine
is running.
Stop the engine and disconnect the spark plug lead
before clearing blockages or unclogging
chute;
before checking, cleaning, or working on
the mower;
after striking a foreign object. Inspect the
mower for damage and make repairs before restarting and operating the mower;
if mower starts to vibrate abnormally (check
immediately).
Stop the engine
whenever you leave the mower; – before refuelling.

Page 6
Safety
Reduce the throttle setting during engine run-out
and, if the engine is provided with a shut-off valve, turn the fuel off at the conclusion of mowing.
Stop the blade(s) when crossing gravel drives,
walks, or roads.
Shut the engine (motor) off and wait until the
blade comes to complete stop before removing grass catcher
.
Do not operate the mower while under the
influence of alcohol or drugs.
If the equipment should start to vibrate
abnormally, stop the engine (motor) 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. The operator could lose footing or balance.
Do not mow on wet grass. Reduced footing could
cause slipping.
tamper with safety devices. Check their proper
operation regularly.
Keep the mower free of grass, leaves, or other
debris build-up. Clean up oil or fuel spillage.
Stop and inspect the equipment if you strike an
object. Repair, if necessary, before restarting.
Never attempt to make wheel height adjustments
while the engine (motor) is running.
Always disconnect electric mowers (live operated)
before cleaning, repairing, or adjusting.
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.
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 engine governor setting or
overspeed the engine.
To ensure the best performance and safety,
purchase only genuine Toro replacement parts and accessories.
Do not use “will fit” parts and
accessories; they may cause a safety hazard.
Maintenance and Storage
Keep all nuts, bolts (especially blade attachment
bolts), and screws tight to be sure the equipment is in safe working condition.
Never store the equipment with gasoline in the
tank inside a building where fumes may reach an open flame or spark.
Allow the engine to cool before storing 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 for safety.
Use extra care when handling gasoline; vapors are
explosive.

Gasoline and Oil
Recommended
Use UNLEADED Regular Gasoline suitable for automotive use (85 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.
POTENTIAL HAZARD
Gasoline
In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
A fire or explosion from gasoline can burn
you, others, and cause property damage.
HOW TO AV
OID THE HAZARD
Use a funnel and 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” (6 mm 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.
POTENTIAL HAZARD
When fueling, under certain circumstances,
a static charge can develop, igniting the gasoline.
WHAT CAN HAPPEN
A fire or explosion from gasoline can burn
you and others and cause property damage.
HOW TO AV
OID THE HAZARD
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, r

Adjusting
Height-of-Cut
A 25mm to 108mm (1” to 4-1/4”) range for height-of-cut can be achieved by adjusting blade spacers, rear axle height and front castor spacers. Use the Height-of-Cut chart on page 26 to select the combination required
Adjust Blade Height
Blades are adjusted by using the four, 6.35mm (1/4”) spacers found on the blade spindle bolts. This allows a range, in 6.35mm (1/4”) increments, of cutting height in any axle position. The same number of blade spacers must be used on all blades to achieve a level cut (two above and two below, one above and three below, etc.).
1. Stop engine and remove spark plug wire(s).
2. Hold blade bolt and remove nut. Slide bolt
down, through spindle, and change spacers as required (Fig. 19).
3. Insert bolt, add extra spacer(s), and secure with
thin washer and nut (Fig. 19).
4. Torque blade bolt to 101–108 NSm
(75–80 ft. lb.).

Adjust Axle Height
Desired height-of-cut range can be obtained by adjusting the rear axle and placing caster spacers above or below the caster arm (see chart).
1. Stop engine, remove spark plug wire(s) and belt
guard (Fig. 20).
2. Loosen but do not remove the (2) axle pivot
bolts and the (2) axle adjustment bolts (Fig. 20).
3. Place a jack under the rear center of the engine
frame. Raise the back end of the engine frame up enough to remove front (2) axle adjustment bolts (Fig. 20).
4. Raise or lower the engine frame with the jack,so
that front (2) axle adjustment bolts can be installed in the desired hole location (Fig. 20). A tapered punch can be used to help align the holes.
5. Tighten all (4) bolts and lower the unit.
6. Adjust control rods and brake linkages as

Spark
Plug
Service Interval/Specification
Check the spark plug(s) after every 200 operating hours. Make sure the air gap between the center and side electrodes is correct before installing the spark plug. Use a spark plug wrench for removing and installing the spark plug(s) and a gapping tool/feeler gauge to check and adjust the air gap. Install a new spark plug(s) if necessary.
Type: Champion RC12YC (or equivalent) Air Gap:
1.02 mm (0.040 in.).
Removing the Spark Plug(s)
1. Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to “OFF” to stop the engine. Remove the key.
2. Pull the wire(s) off the spark plug(s) (Fig. 29).
Now clean around the spark plug(s) to prevent dirt from falling into the engine and potentially causing damage.
Checking the Spark Plug
1. Look at the center of the spark plug(s) (Fig. 30).
If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty.
IMPORTANT: Never clean the spark plug(s). Always r a black coating, worn electrodes, an oily film, or cracks.
2. Check the gap between the center and side
electrodes (Fig. 30). Bend the side electrode (Fig. 30) if the gap is not correct.
