death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
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.
Safety
This machine meets or exceeds CEN standard EN
836:1997, ISO standard 5395:1990, and ANSI
B71.4-1999 specifications in effect at the time of
production when 40 lb. of ballast is added to the rear
wheel.
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 the CEN standard EN
836:1997, ISO standard 5395:1990, and 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.
•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.

4
•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
refuelling.
– 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.
•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.
•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;
– 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.
•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 before stopping engine 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.

5
•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 reels if not mowing.
•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,
battery compartment and fuel storage area free of grass,
leaves, or excessive grease.
•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-reel machines, take care as rotating one reel
can cause other reels to rotate.
•Disengage drives, lower the cutting units, set parking
brake and stop engine. Wait for all movement to stop
before adjusting, cleaning or repairing.
•Clean grass and debris from cutting units, drives,
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 before making any repairs.
Disconnect the negative terminal first and the positive
last. Reconnect positive first and negative last.
•Use care when checking the 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 CEN, ISO, or 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.
•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.
•The operator must be skilled and trained in how to drive
on hillsides. Failure to use caution on slopes or hills
may cause loss of control and cause the vehicle to tip or
roll, possibly resulting in personal injury or death.
•Handle gasoline 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 four interlock switches in the safety system,
regardless if they are working properly or not.
•Before starting the engine, sit on the seat, depress the
lift pedal, and release it to ensure that the cutting units
are disengaged. Verify that the traction system is in
neutral and the parking brake is set.
•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.

6
•The grass baskets must be in place during operation of
the reels or thatchers for maximum safety. Shut the
engine off before emptying the baskets.
•Raise the cutting units when driving from one work
area to another.
•Do not touch the engine, 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.
•Stay clear of the rotating screen at the side of the engine
to prevent direct contact with your body or clothing.
•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.
•Before getting off of the seat, move the functional
control lever to neutral (N), raise the cutting units and
wait for the reels to stop spinning. Set the parking
brake. Stop the engine and remove the key from the
ignition switch.
•Whenever the machine is left unattended, make sure
that the cutting units are fully raised and the reels are
not spinning, the key is removed from the ignition
switch, and the parking brake is set.
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.
•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.
•The engine must be shut off before checking the oil or
adding oil to the crankcase.
•To ensure safety and accuracy, have an Authorized Toro
Distributor check the maximum engine speed with a
tachometer. Maximum governed engine speed should be
2900 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.

Before Operating
Checking the Engine Oil
The engine uses any high-quality detergent oil having the
American Petroleum Institute (API) service classification
of CD, CE, CF or CF-4 or CG-4 or higher. The
recommended viscosity (weight) is SAE 10W30.
The engine is shipped with 3.5 quarts (w/ filter) (3.3 l) of
oil in the crankcase; however, the level of oil must be
checked before and after the engine is first started.
1. Position the machine on a level surface.
2. Remove the dipstick and wipe it with a clean rag
(Fig. 23). Push the dipstick into the tube and make sure
it is seated fully. Remove the dipstick from the tube and
check the level of oil. If the oil level is low, remove the
filler cap from the valve cover and slowly add enough
oil to raise the level to the Full mark on the dipstick.
Add the oil slowly and check the level often during this
process. Do not overfill.
Important Make sure that the dipstick is removed
while filling the engine with oil.When adding engine oil or
filling oil, there must be clearance between the oil fill
device and the oil fill hole in the valve cover as shown in
figure 22. This clearance is necessary to permit venting
when filling, which prevents oil from overrunning into
breather.
Figure 22

Figure 23
1. Dipstick 2. Filler cap
3. Replace the dipstick.
4. Start and run the engine at idle for 30 seconds, then shut
the engine off. Wait 30 seconds, then repeat steps 2–3.
Important Check the level of oil every 8 operating
hours or daily. Change the oil and filter initially after the
first 50 hours of operation, thereafter change the oil every
50 hours and the filter every 100 hours. However, change
the oil more frequently when the engine is operated in
extremely dusty or dirty conditions.
5. Install the filler cap and dipstick firmly in place.
Filling the Fuel Tank
The engine runs on No. 2 diesel fuel.
The fuel tank capacity is approximately 6 gallons (22.7 l).
1. Clean the area around the fuel tank cap (Fig. 24).
