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.
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 standard
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
this manual, it is the owner’s responsibility to explain
this material to them.
•Never allow children or people unfamiliar with these
instructions to use 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 himself or herself,
other people, or 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.

4
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 tank and container caps securely.
•Replace faulty silencers/mufflers.
•Before using, always visually inspect to see that the
blades, blade bolts, and cutting assembly are not worn
or damaged. Replace worn or damaged blades and bolts
in sets to preserve balance.
•On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.
•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.
•Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.
•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. Only start the engine from the
operator’s position. Use seat belts, if provided.
•Do not use this machine on slopes greater than 13°.
•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 speed changes should be gradual,
especially when travelling downhill.
– The machine speed 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
machine is designed for that 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, stop the engine, and
remove the ignition key:
– before clearing blockages;
– before checking, cleaning, or working on the
machine;
– after striking a foreign object. Inspect the machine
for damage and make repairs before restarting and
operating the equipment;
– if the machine starts to vibrate abnormally (check
immediately).

5
•Disengage drive to attachments when transporting or
not is use.
•Stop the engine and disengage drive to attachment:
– before refuelling;
– before making height adjustment unless adjustment
can be made from the operator’s position.
•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.
•Never raise deck with the blades running.
•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.
•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.
•The operator shall turn on flashing warning lights, if
provided, whenever traveling on a public road, except
where such use is prohibited by law.
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
and do not store near flame.
•To reduce the fire hazard, keep the engine,
silencer/muffler, battery compartment, cutting units,
drives, and fuel storage area free of grass, leaves, or
excessive grease. Clean up oil or fuel spillage.
•Replace worn or damaged parts for safety.
•If the fuel tank has to be drained, do this outdoors.
•On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.
•When machine is to be parked, stored, or left
unattended, lower the cutting units unless a positive
mechanical lock is provided.
•Disengage drives, lower the cutting units, move traction
pedal to Neutral, set parking brake, stop engine and
remove key from ignition. Wait for all movement to
stop before adjusting, cleaning or repairing.
•Shut off fuel while storing or transporting. Do not store
fuel near flames.
•Park machine on level ground. Never allow untrained
personnel to service machine.
•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 blades. Wrap the blades or
wear gloves, and use caution when servicing them.
Only replace blades. Never straighten or weld 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 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
standards.
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.

Warning
Operation
•Before operating a machine with ROPS (roll over
protection system), be certain that the seat belts are
attached and the seat is latched to prevent the seat from
pivoting forward.
•Know how to stop the machine and engine quickly.

6
•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.
•Keep hands, feet, and clothing away from moving parts
and the mower discharge area and underside of the
mower while the engine is running.
•Fill fuel tank until level is 1 in. (25 mm) below the
bottom of the filler neck. Do not overfill.
•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,
regardless if they are working properly or not.
•Check carefully for overhead clearances (i.e. branches,
doorways, electrical wires) before driving under any
objects and do not contact them.
•Do not mow in reverse unless absolutely necessary.
•Reduce speed when making sharp turns.
•If a steep slope must be ascended, back up the hill and
drive forward down the hill, keeping the machine in
gear.
•If you cannot back up a slope or if you feel uneasy on it,
do not mow it.
•Avoid starting or stopping on a slope. If tires lose
traction, disengage the blades and proceed slowly
straight down the slope. Avoid raising the wing cutting
units on a slope.
•Avoid turning on slopes. If you must turn, turn slowly
and gradually downhill, if possible.
•When operating the machine on slopes, banks, or near
drop offs, always have the ROPS installed.
•When operating a machine with a ROPS, always use a
seat belt.
•Be certain that the seat belt can be released quickly if
the machine is driven or rolls into a pond or water.
•Watch for traffic when near or crossing roads. Always
yield the right-of-way.
•Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly turn over if a wheel goes
over the edge of a cliff or ditch, or if an edge caves in.
•Do not mow on wet grass. Reduced traction could cause
sliding.
•Do not try to stabilize the machine by putting your foot
on the ground.
•Use extra care with other attachments. These can
change the stability of the machine.
•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.
•Turn off the blades when not mowing.
Maintenance and Storage
•Do not touch equipment or attachment parts which may
be hot from operation. Allow to cool before attempting
to maintain, adjust, or service.
•Never store the machine or fuel container inside where
there is an open flame, such as near a water heater or
furnace.
•Keep nuts and bolts tight, especially the blade
attachment bolts. Keep equipment in good condition.
•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. If fluid is injected into the skin it must be
surgically removed within a few hours by a doctor
familiar with this form of injury or gangrene may result.
•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. Keep everyone away.
•Check brake operation frequently. Adjust and service as
required.
•Battery acid is poisonous and can cause burns. Avoid
contact with skin, eyes, and clothing. Protect your face,
eyes, and clothing when working with a battery.
•Battery gases can explode. Keep cigarettes, sparks, and
flames away from the battery.
•The engine must be shut off before checking the oil or
adding oil to the crankcase.
•If major repairs are ever needed or if assistance is
desired, contact an Authorized Toro Distributor.
•To make sure of optimum performance and continued
safety certification of the machine, use only genuine
Toro replacement parts and accessories. Replacement
parts and accessories made by other manufacturers
could be dangerous, and such use could void the
product warranty.

Before Operating
If you leave the key in the ignition switch, someone
could accidently start the engine and seriously
injure you or other bystanders.
Remove the key from the ignition before you do
any maintenance.
Caution
Checking the Engine Oil
The engine is shipped with oil in the crankcase; however,
the oil level must be checked before and after the engine is
first started.
Crankcase capacity is approximately 8 qt. (7.6 l) with the
filter.
Use high-quality engine oil that meets the following
specifications:
API Classification Level Required: CH–4, CI–4 or
higher.
Preferred oil: SAE 15W–40 (above 0_F)
Alternate oil: SAE 10W–30 or 5W–30
(all temperatures)
Toro Premium Engine oil is available from your distributor
in either 15W–40 or 10W–30 viscosity. See the parts
catalog for part numbers.
1. Park the machine on a level surface. Unlock the engine
cover latches.
2. Open the engine cover.
3. Remove the dipstick, wipe it clean, install the dipstick
into the tube, and pull it out again. The oil level should
be up to the FULL mark (Fig. 1).

1. Oil fill cap
Note: When using different oil, drain all old oil from the
crankcase before adding new oil.
5. Install the oil fill cap and dipstick.
6. Close the engine cover and secure it with the latches.
Checking the Cooling System
Check level of coolant at the beginning of each day.
Capacity of system is 2-3/4 gal. (10.4 l).
1. Carefully remove the radiator cap and expansion tank
cap (Fig. 3).
If the engine has been running, the pressurized,
hot coolant can escape and cause burns.
•Do not open the radiator cap when the engine is
running.
•Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
Caution
2. Check the coolant level in the radiator. The radiator
should be filled to the top of the filler neck and the
expansion tank filled to the FULL mark.

3. If the coolant is low, add a 50/50 mixture of water and
ethylene glycol anti-freeze. Do not use water only or
alcohol/methanol base coolants.
4. Install the radiator cap and expansion tank cap.
Filling the Fuel Tank
The capacity of the fuel tank is 19 gallons (72 l).
1. Remove the fuel tank cap (Fig. 4).
2. Fill the tank to about 1 inch (25 mm) below the top of
the tank, not the filler neck, with No. 2 diesel fuel. Then
install the cap.

Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
•Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
•Do not fill the fuel tank completely full. Add fuel
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 the fuel to expand.
•Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
•Store fuel in a clean, safety-approved container
and keep the cap in place.
Checking the Hydraulic Fluid
The machines reservoir is filled at the factory with
approximately 8 U.S. gallons (30 l) of high quality
hydraulic fluid. Check the level of the hydraulic fluid
before the engine is first started and daily thereafter.
The recommended replacement fluid is:
Toro Premium All Season Hydraulic Fluid
(Available in 5 gallon pails or 55 gallon drums. See
parts catalog or Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other
fluids may be used provided they meet all the following
material properties and industry specifications. We do not
recommend the use of synthetic fluid. Consult with your
lubricant distributor to identify a satisfactory product Note:
Toro will not assume responsibility for damage caused by
improper substitutions, so use only products from reputable
manufacturers who will stand behind their
recommendation.

Note: Many hydraulic fluids are almost colorless, making it
difficult to spot leaks. A red dye additive for the hydraulic
system oil is available in 2/3 oz. (20 ml) bottles. One bottle
is sufficient for 4–6 gal (15–22 1) of hydraulic oil. Order
part no.44–2500 from your authorized Toro distributor.
Biodegradable Hydraulic Fluid – Mobil 224H
Toro Biodegradable Hydraulic Fluid
(Available in 5 gallon pails or 55 gallon drums. See
parts catalog or Toro distributor for part numbers.)
Alternate fluid: Mobil EAL 224H
This is vegetable–oil based biodegradable oil tested and
approved by Toro for this model. This fluid is not as
resistant to to high temperatures as standard fluid, so install
an oil cooler if required by the operator manual and follow
recommended fluid change intervals with this fluid.
Contamination by mineral–based hydraulic fluids will
change the biodegradability and toxicity of this oil. When
changing from standard fluid to the biodegradable type, be
certain to follow the approved flushing procedure. Contact
your local Toro Distributor for details.
1. Position the machine on a level surface, lower the
cutting units, stop the engine, and remove the key.
2. Unlatch the seat, raise it, and engage the prop rod.
3. Clean the area around the filler neck and cap of the
