Safety
This machine meets or exceeds CEN standard EN
836:1997 (when appropriate decals applied), and ANSI
B71.4-1999 specifications in effect at the time of
production when equipped with required weights 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 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.
•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 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 the task;

4
•lack of awareness of the effect of ground
conditions, especially slopes.
•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 hearing
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 tank 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.
•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.
– Use counterweight(s) or wheel weights when
suggested in the operator’s manual.
•Stay alert for holes in the terrain and other hidden
hazards.
•Watch out for traffic when crossing or near roadways.
•Stop the blades from 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 making height adjustment unless adjustment
can be made from the operator’s position.
– before clearing blockages;
– before checking, cleaning or working on the mower;

5
– 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. Torque all the spindle pulley nuts to
130–150 ft–lbs.;
•Reduce the throttle setting before stopping the engine
and, if the engine is provided with a fuel 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 blades from rotating.
•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 onto 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 fuel storage area,
cutting units and drives free of grass, leaves, or
excessive grease. Clean up oil or fuel spillage.
•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. Wait for all
movement to stop before adjusting, cleaning or
repairing.
•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 blades. 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.
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
•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 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.

6
•Using the machine demands attention. To prevent loss
of control:
– Do not drive close to sand traps, ditches, creeks,
embankments, 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.
•When operating a machine on slopes, by banks, or drop
offs, always have ROPS (roll–over protection system)
installed.
•When operating a machine with ROPS (roll–over
protection system) always use the seat belt and make
sure seat pivot retainer pin is installed (GM only).
•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.
•Raise the cutting units when driving from one work
area to another but they must be lowered when going
down slopes to maintain steering control.
•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.
•On any hill, there is the possibility of tipping or rolling
over, but the risk increases as the slope angle increases.
Steep hills should be avoided.
•Engage traction drive slowly, always keep foot on
traction pedal, especially when traveling downhill.
– Use reverse on traction pedal for braking.
•If the machine stalls when climbing 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.
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.
•To ensure safety and accuracy, have an Authorized Toro
Distributor check the maximum engine speed with a
tachometer.
•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 is shipped with 8.5 qt. (8 l) of oil in the
crankcase. However, check level of oil before and after the
engine is first started.
The engine uses any high quality detergent oil having the
American Petroleum Institute (API) “service classification”
CH–4, CI–4 or higher.
Use the following chart to select the appropriate oil
viscosity according to the ambient temperature.
Recommended oil viscosity is SAE 15W–40 for all
seasons.
Ambient Temperature Oil Viscosity
23°to 104°F (–5°to 40°C) SAE 30
41°to 122°F (5°to 50°C) SAE 40
5°to 122°F (–15°to 50°C) SAE 15W–40
–13 to 104°F (–25°to 40°C) SAE 10W–30
–22°to 68°F (–30°to 20°C) SAE 5W–20
Toro Premium Engine oil is available from your distributor
in either 15W–40 or 10W–30 viscosity. See the parts
catalog for part numbers.
Important After the engine is operated, the oil drains
back to the oil pan very slowly. Before checking the oil
level, allow adequate time for the oil to drain back to the
pan so an accurate measurement can be attained.
1. Be sure machine is positioned on a level surface.
2. Unlatch hood and raise and prop it open (Fig. 3). Make
sure hood prop is secured in one of the mounting
brackets on hood. Unlatch and remove the left side
panel.

3. Remove dipstick (Fig. 5), wipe with a clean rag, and
insert into tube until fully seated. Remove dipstick from
tube and check oil level. If oil level is low, remove filler
cap (Fig. 6). Add proper type of oil until level is
between the upper and lower holes on the dipstick
(Fig. 7). Do not overfill.

Important Check oil after every 5 hours operation or
daily. Change oil and filter after the first 50 hours, then
change both every 100 hours operation thereafter. Change
oil and filter more frequently when engine is operated in
extremely dusty or dirty conditions.
4. Insert dipstick into tube and close and latch hood.

Checking the Cooling System
The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol anti-freeze. Check coolant
level at beginning of each day before starting the engine.
Capacity of cooling system is approximately 3.9 gal.
(14.7 l).
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
1. Unlatch, raise and prop hood open. Make sure hood
prop is secured in one of the mounting brackets on
hood.
2. Check level of coolant in expansion tank (Fig. 8). The
expansion tank must be filled to the FULL mark.

Figure 8
1. Expansion tank 2. Expansion tank cap
3. If coolant level is low, add a 50/50 solution of water and
permanent ethylene glycol anti-freeze. Do not use
alcohol/methanol base coolants or water only. Do not
overfill.
4. Remove expansion tank cap and fill expansion tank to
the FULL mark.
5. If adding large quantities of solution, remove radiator
cap (Fig. 9) and fill radiator until level of coolant is
above the radiator core and about 1 in. (25 mm) below
bottom of filler neck.

6. Install radiator cap and expansion tank cap.
7. Close and latch the hood.
Checking the Hydraulic System
Fluid
1. Fluid level should be checked daily through sight glass
at rear of hydraulic reservoir (Fig. 10). When oil is cold,
level will be slightly below center, but should be in the
middle of the sight glass when the oil is warm.

2. If oil level is low, add hydraulic oil to the reservoir
(Fig. 10); refer to Servicing the Hydraulic System,
page 44.
Filling the Fuel Tank
The engine runs on ASTM No. 2-D diesel fuel.
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.
1. Remove fuel tank cap (Fig. 11).
2. Fill tank to about 1 in. (25 mm) below bottom of filler
neck with No. 2 diesel fuel. Install cap.

Checking the Tire Pressure
Since the machine can be operated under many different
types of turf conditions, proper tire pressure is very
important. Use the following as a guide:
Traction Unit Tires
•Under Normal mowing conditions and when used on a
wide variety of turf grasses: 15 psi (100 kPa) front; 13
psi (90 kPa) rear.
•When turf is wet and softer than normal, use low
pressure: 12 psi (80 kPa) front and 9 psi (60 kPa) rear.
•When turf is dry and harder than normal, use higher tire
pressure: 18 psi (120 kPa) front and rear.
Castor Wheel Tires
•All conditions use 50 psi (340 kPa) castors.
Checking Systems Operation
Start engine. Move the machine, slowly, to an area where
the machine can be checked for proper function. Check
operation of controls, safety interlock system, engine,
hydraulic system, brakes and cutting units; refer to
Operation, page 23, for proper procedures.
Checking Cutting Unit
Mismatch
To ensure all cutting units are at the same height-of-cut:
1. Adjust all cutting units to the highest height–of–cut.
Position all castor arm height-of-cut spacers to on the
underside of the castor arms. Do not move washers.
Leave them in their original position.
Note: Unless all castor wheel axles are not in the same
location, axles do not have to be relocated. All, however
must be in the same holes (Fig. 12).
2. Place a flat 4’x8’ sheet of 3/4 in. plywood on a level
surface and lower a cutting unit onto the plywood.
3. Taking each cutting blade in turn, position blade so it
faces fore and aft. Measure from plywood to front tip of
cutter blade and record dimension. All blade heights on
same deck should be within 1/4 in. (6.3 mm) of one
another. If blade heights meet criteria, proceed to step 5.
If blade heights are not within 1/4 in. (6.3 mm), proceed
to step 4.
4. To match cutting blade height, transfer washers from
one side of a castor wheel arm to the other. If end is to
be lowered, transfer one or both washers from the
underside to the top. By contrast, if end is to be raised,
transfer washer(s) from the top to the underside. Each
washer is 1/8 in. (3 mm) thick. Repeat measurement of
blade tip height and record new dimensions.
5. Repeat steps 2–3 on remaining cutting units, and step 4,
if necessary. If washers are transferred on a outboard
cutting unit castor arm, be sure to transfer the same
number on both ends of the castor arm.
6. Compare blade height dimensions of all cutting units.
Blade heights must be within 3/8 in. (9.5 mm) of one
another. If they are not, determine which cutting unit
