Safety
This machine meets or exceeds ANSI B71.4-1999
specifications in effect at the time of production when
and equipped with rear weight as listed in the weight
chart.
Improper use or maintenance by the operator or owner
can result in injury. To reduce the potential for injury,
comply with these safety instructions and always pay
attention to the safety alert symbol, which means
CAUTION, WARNING, or DANGER—“personal
safety instruction.” Failure to comply with the
instruction may result in personal injury or death.
Safe Operating Practices
The following instructions are from ANSI B71.4-1999.
Training
•Read the operator’s manual and other training material
carefully. Be familiar with the controls, safety signs,
and the proper use of the equipment.
•If the operator or mechanic can not read the language of
is the owner’s responsibility to explain this material to
them.
•Never allow children or people unfamiliar with these
instructions to use or service the mower. Local
regulations may restrict the age of the operator.
•Never mow while people, especially children, or pets
are nearby.
•Keep in mind that the operator or user is responsible for
accidents or hazards occurring to other people or their
property.
•Do not carry passengers.
•All drivers and mechanics should seek and obtain
professional and practical instruction. The owner is
responsible for training the users. Such instruction
should emphasize:
– the need for care and concentration when working
with ride-on machines;
– control of a ride-on machine sliding on a slope will
not be regained by the application of the brake. The
main reasons for loss of control are:
•insufficient wheel grip;
•being driven too fast;
•inadequate braking;
•the type of machine is unsuitable for its task;
•lack of awareness of the effect of ground
conditions, especially slopes;
•incorrect hitching and load distribution.
•The owner/user can prevent and is responsible for
accidents or injuries occurring to himself or herself,
other people, or property.
Preparation
•While mowing, always wear substantial footwear, long
trousers, hard hat, safety glasses, and ear protection.
Long hair, loose clothing, or jewelry may get tangled in
moving parts. Do not operate the equipment when
barefoot or wearing open sandals.
•Thoroughly inspect the area where the equipment is to
be used and remove all objects which may be thrown by
the machine.
•Warning—Fuel is highly flammable. Take the
following precautions:
– Store fuel in containers specifically designed for this
purpose.
– Refuel outdoors only and do not smoke while
refueling.
– Add fuel before starting the engine. Never remove
the cap of the fuel tank or add fuel while the engine
is running or when the engine is hot.
– If fuel 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 fuel vapors have dissipated.
– Replace all fuel tanks and container caps securely.
•Replace faulty silencers/mufflers.
•Evaluate the terrain to determine what accessories and
attachments are needed to properly and safely perform
the job. Only use accessories and attachments approved
by the manufacturer.
•Check that operator’s presence controls, safety switches
and shields are attached and functioning properly. Do
not operate unless they are functioning properly.
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.
•Before attempting to start the engine, disengage all
blade attachment clutches, shift into neutral, and engage
the parking brake.
•Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.

5
•Do not use on slopes of more than
–20°when mowing across a slope
–30°when mowing up or down a slope
•The maximum value of 50% of the limit of stability for
EN836 is
–10°when mowing across a slope
–15°when mowing up or down a slope
•Remember there is no such thing as a safe slope. Travel
on grass slopes requires particular care. To guard
against overturning:
– do not stop or start suddenly when going up or
downhill;
– engage clutch slowly, always keep machine in gear,
especially when travelling downhill;
– machine speeds should be kept low on slopes and
during tight turns;
– stay alert for humps and hollows and other hidden
hazards;
– never mow across the face of the slope, unless the
mower is designed for this purpose.
•Stay alert for holes in the terrain and other hidden
hazards.
•Use care when pulling loads or using heavy equipment.
– Use only approved drawbar hitch points.
– Limit loads to those you can safely control.
– Do not turn sharply. Use care when reversing.
– Use counterweight(s) or wheel weights when
suggested in the operator’s manual.
•Watch out for traffic when crossing or near roadways.
•Stop the blades rotating before crossing surfaces other
than grass.
•When using any attachments, never direct discharge of
material toward bystanders nor allow anyone near the
machine while in operation.
•Never operate the machine with damaged guards,
shields, or without safety protective devices in place. Be
sure all interlocks are attached, adjusted properly, and
functioning properly.
•Do not change the engine governor settings or
overspeed the engine. Operating the engine at excessive
speed may increase the hazard of personal injury.
•Before leaving the operator’s position:
– stop on level ground;
– disengage the power take-off and lower the
attachments;
– change into neutral and set the parking brake;
– stop the engine and remove the key.
•Disengage drive to attachments when transporting or
not in use.
•Stop the engine and disengage drive to attachment
– before refuelling;
– before removing the grass catcher/catchers;
– before making height adjustment unless adjustment
can be made from the operator’s position.
– before clearing blockages;
– before checking, cleaning or working on the mower;
– after striking a foreign object or if an abnormal
vibration occurs. Inspect the mower for damage and
make repairs before restarting and operating the
equipment.
•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.
•Keep hands and feet away from the cutting units.
•Look behind and down before backing up to be sure of
a clear path.
•Slow down and use caution when making turns and
crossing roads and sidewalks. Stop cylinders/reels if not
mowing.
•Be aware of the mower discharge direction and do not
point it at anyone.
•Do not operate the mower under the influence of
alcohol or drugs
•Use care when loading or unloading the machine into a
trailer or truck
•Use care when approaching blind corners, shrubs, trees,
or other objects that may obscure vision.
Maintenance and Storage
•Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
•Never store the equipment with fuel 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,
silencer/muffler, battery compartment and fuel storage
area free of grass, leaves, or excessive grease.

6
•Check the grass catcher frequently for wear or
deterioration.
•Keep all parts in good working condition and all
hardware and hydraulic fittings tightened. Replace all
worn or damaged parts and decals.
•If the fuel tank has to be drained, do this outdoors.
•Be careful during adjustment of the machine to prevent
entrapment of the fingers between moving blades and
fixed parts of the machine.
•On multi-spindle mowers, take care as rotating one
blade can cause other blades to rotate.
•Disengage drives, lower the cutting units, set parking
brake, stop engine and remove key and disconnect spark
plug wire. Wait for all movement to stop before
adjusting, cleaning or repairing.
•Clean grass and debris from cutting units, drives,
silencers/mufflers, and engine to help prevent fires.
Clean up oil or fuel spillage.
•Use jack stands to support components when required.
•Carefully release pressure from components with stored
energy.
•Disconnect battery and remove spark plug wire before
making any repairs. Disconnect the negative terminal
first and the positive last. Reconnect positive first and
negative last.
•Use care when checking the cylinders/reels. Wear
gloves and use caution when servicing them.
•Keep hands and feet away from moving parts. If
possible, do not make adjustments with the engine
running.
•Charge batteries in an open well ventilated area, away
from spark and flames. Unplug charger before
connecting or disconnecting from battery. Wear
protective clothing and use insulated tools.
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 standard.
This product is capable of amputating hands and feet and
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
Use of this product for purposes other than its intended use
could prove dangerous to user and bystanders.
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.
Warning
•Know how to stop the engine quickly.
•Do not operate the machine while wearing tennis shoes
or sneakers.
•Wearing safety shoes and long pants is advisable and
required by some local ordinances and insurance
regulations.
•Handle fuel carefully. Wipe up any spills.
•Check the safety interlock switches daily for proper
operation. If a switch should fail, replace the switch
before operating the machine. After every two years,
replace all interlock switches in the safety system,
whether they are working properly or not.
•Before starting the engine, sit on the seat.
•Using the machine demands attention. To prevent loss
of control:
– Do not drive close to sand traps, ditches, creeks, or
other hazards.
– Reduce speed when making sharp turns. Avoid
sudden stops and starts.
– When near or crossing roads, always yield the
right-of-way.
– Apply the service brakes when going downhill to
keep forward speed slow and to maintain control of
the machine.
•Raise the cutting units when driving from one work
area to another.
•Do not touch the engine, silencer/muffler, or exhaust
pipe while the engine is running or soon after it has
stopped because these areas could be hot enough to
cause burns.
•If the engine stalls or loses headway and cannot make it
to the top of a slope, do not turn the machine around.
Always back slowly, straight down the slope.
•When a person or pet appears unexpectedly in or near
the mowing area, stop mowing. Careless operation,
combined with terrain angles, ricochets, or improperly
positioned guards can lead to thrown object injuries. Do
not resume mowing until the area is cleared.

7
Maintenance and Storage
•Make sure all hydraulic line connectors are tight and all
hydraulic hoses and lines are in good condition before
applying pressure to the system.
•Keep your body and hands away from pin hole leaks or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not your hands, to search for
leaks. Hydraulic fluid escaping under pressure can have
sufficient force to penetrate the skin and cause serious
injury. Seek immediate medical attention if fluid is
injected into skin.
•Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be
relieved by stopping the engine and lowering the cutting
units and attachments to the ground.
•Check all fuel lines for tightness and wear on a regular
basis. Tighten or repair them as needed.
•If the engine must be running to perform a maintenance
adjustment, keep hands, feet, clothing, and any parts of
the body away from the cutting units, attachments, and
any moving parts, especially the screen at the side of the
engine. Keep everyone away.
•To ensure safety and accuracy, have an Authorized Toro
Distributor check the maximum engine speed with a
tachometer. Maximum governed engine speed should be
3200 RPM.
•If major repairs are ever needed or if assistance is
desired, contact an Authorized Toro Distributor.
•Use only Toro-approved attachments and replacement
parts. The warranty may be voided if used with
unapproved attachments.

Filling the Fuel Tank
THE TORO COMPANY STRONGLY
RECOMMENDS THE USE OF FRESH, CLEAN,
UNLEADED REGULAR GRADE GASOLINE IN
TORO GASOLINE POWERED PRODUCTS.
UNLEADED GASOLINE BURNS CLEANER,
EXTENDS ENGINE LIFE, AND PROMOTES GOOD
STARTING BY REDUCING THE BUILD–UP OF
COMBUSTION CHAMBER DEPOSITS. LEADED
GASOLINE CAN BE USED IF UNLEADED IS NOT
AVAILABLE.
Note: Never Use Methanol, Gasoline Containing Methanol,
Gasoline Containing More Than 10% Ethanol, Gasoline
Additives, Premium Gasoline Or White Gas Because
Engine Fuel System Damage Could Result.
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.
•Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1 in.
(25 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.
1. Tip seat forward and prop it with the support rod so
it cannot fall accidentally. Using a clean rag, clean
area around fuel tank cap (Fig. 14).
2. Remove cap from the fuel tank and fill the 6-1/2 gallon
(24 L) tank to within 1 inch (25 mm) from the top with
gasoline. DO NOT OVERFILL.
3. Install fuel tank cap tightly after filling tank.

Check Cooling System
Clean debris off screen and radiator/oil cooler daily, more
often if conditions are extremely dusty and dirty.
The cooling system is filled with a 50 / 50 solution of water
and permanent ethylene glycol anti–freeze. Check level of
coolant in expansion tank at beginning of each day before
starting the engine. Capacity of cooling system is 6 quarts
(5.6 l).
•If engine has been running, pressurized hot
coolant can escape when radiator cap is
removed and cause burns.
Caution
1. Carefully remove radiator cap. Coolant is pressurized
and may be hot if engine has been running.
2. Check level of coolant in radiator. Level of coolant
must be above the core and about 1 inch (25 mm) below
bottom of filler neck.
3. If coolant level is low, replenish the system. DO NOT
OVERFILL.
4. Install radiator cap.
