Toro Mower Safety
The following list contains safety information specific
to Toro products or other safety information that you
must know.
This product can amputate hands and feet and throw
objects. Always follow all safety instructions to avoid
5

serious injury or death.
Using this product for purposes other than its intended
use could be dangerous to the user and bystanders.
Operation
• Always wear substantial shoes. Do not operate
the machine while wearing sandals, tennis shoes,
or sneakers.
• Wearing safety shoes and long pants is advisable
and required by some local ordinances and
insurance regulations.
• Fill the fuel tank until the 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 three interlock
switches in the safety system, regardless of
whether or not they are working properly.
• The grass deflector(s) must always be installed
and in the lowest position on the cutting unit.
• Pay attention when using the machine. To
prevent loss of control:
– Drive slowly.
– Do not drive close to sand traps, ditches,
creeks, or other hazards.
– Reduce speed when making sharp turns.
Avoid sudden stops and starts.
– Lower the cutting unit when going down
slopes.
• Do not touch the engine, radiator, or muffler
while the engine is running or soon after it has
stopped because these areas might burn you.
• If a cutting blade strikes a solid object or vibrates
abnormally, disengage the power take off, move
the throttle to Slow, set the parking brake, stop
the engine, and remove the ignition key. Wait for
all motion to stop, and inspect the machine for
damage. Repair or replace any damaged parts
before operating. Ensure that the cutting blades
are in good condition and the blade bolts are
torqued to proper specifications (see the cutting
deck operator’s manual).
• Check carefully for overhead clearances such as
branches, doorways, and electrical wires before
driving under any objects. Do not contact the
objects.
• Make sure that the set belt can be removed
quickly if the machine is driven or rolls into a
pond or lake.
• If the engine stalls or the machine loses headway
and cannot get to the top of a slope, do not turn
the machine around. Always back slowly straight
down the slope.
• If the cutting unit discharge area ever plugs,
disengage the power take off and shut the engine
off before removing the obstruction.
• When operating a 4-wheel drive machine or any
machine on slopes, by banks, or drop offs,
always have the roll-over protection system
installed.
• When operating the machine with the roll-over
protection system, always use the seat belt and
make sure that the seat pivot retaining pin is
installed.
Maintenance and Storage
• Before servicing or making adjustments, stop the
engine and remove the ignition key.
• Ensure that the entire machine is properly
maintained and in good operating condition.
Frequently check all nuts, bolts, and screws.
Check all cutting unit blade bolts frequently to
ensure that they are torqued to proper
specifications (see the cutting deck operator’s
manual).
• Make sure all hydraulic line connectors are tight
and all hydraulic hoses and lines are in good
6

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.
• If the engine must be running to perform a
maintenance adjustment, keep hands, feet,
clothing, and all body parts away from the
cutting units, attachments, power take off shaft,
and any moving parts.
• Do not overspeed the engine by changing
governor settings. To ensure safety and accuracy,
have an authorized Toro distributor check the
maximum engine speed with a tachometer.
Maximum governed engine speed with no load
should be 3200–3250 RPM.
• The engine must be shut off before checking the
oil or adding oil.
• Periodically inspect the roll bar and roll bar
mounting.
Replace, if necessary. Do not modify roll over
protection frames or structures because they are
specifically designed, sized, located, and tested
for injury reduction. If a rollover occurs, a
modified roll-over protection system will not
provide adequate protection.
• If major repairs are ever needed or if assistance is
desired, contact an authorized Toro distributor.
• For 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.

2. If coolant level is low, remove the expansion tank
cap and replenish the system. DO NOT
OVERFILL.
3. Install the expansion tank cap.
Checking the Hydraulic System
Oil
The hydraulic system is designed to operate on any
high-quality detergent oil having the American
Petroleum Institute—API —“ service classification”
SF/CC or CD. Oil viscosity—weight—must be
selected according to anticipated ambient temperature.

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.
DANGER
If the engine has been running, pressurized hot
coolant can escape when the radiator cap is
removed and cause burns.

dipstick cap finger-tight onto the filler neck, then
unscrew the dipstick and check the oil level. If
the level is not within 1⁄2in. (13 mm) from the
groove in the dipstick (Fig. 7), add enough oil to
raise the level to the groove mark. Do not overfill
by more than 1⁄2in. (13 mm) above the groove.
When adding oil to the hydraulic
system, use a funnel with a fine wire screen—
200 mesh—and ensure the funnel and oil are
immaculately clean. This procedure prevents
accidental contamination of the hydraulic system.
3. Screw the dipstick filler cap finger-tight onto the
filler neck. It is not necessary to tighten the cap
with a wrench.
4. Lower the implement.

Controls
Traction Pedal
The traction pedal (Fig. 8) makes the machine move
forward and backward. Using the heel and toe of your
right foot, press the top of the pedal to move forward
and the bottom of the pedal to move backward.
Ground speed is proportionate to how far you press
the pedal. For maximum ground speed with no load,
the traction pedal must be fully depressed while the
throttle is in the FAST position. Maximum speed
forward is approximately 9.5 mph (15 km/h). For
maximum power under a heavy load or when
ascending a hill, have the throttle in the FAST position
while depressing the traction pedal slightly to keep
engine rpm high. If engine rpm begins to decrease,
release the traction pedal slightly to allow engine rpm
to increase.
Turn Pedals
The left- and right-turn pedals (Fig. 8) are connected
to the left and right front wheel brakes, since both
brakes work independently of each other. You can use
the brakes to turn sharply or to increase traction if one
wheel slips while operating on a hillside. However,
wet grass or soft turf could be damaged when you use
brakes to turn.
Tilt Steering Control
The tilt steering control is a lever on the right side of
the steering column (Fig. 8). Pull the lever rearward to
adjust steering wheel to desired fore or aft operating
position and push the lever forward to lock
adjustment.
Brake Pedal
Whenever you shut off the engine, you must engage
the parking brake (Fig. 8) to prevent accidental
machine movement.
The hydrostatic transmission will not, at any time, act
as a parking brake for the machine. To engage the
parking brake, push down fully on the brake pedal and
pull the parking brake knob out; then release the
pedal. To release the parking brake, depress the brake
pedal until the parking brake knob retracts. To stop
quickly, remove your foot from the traction pedal and
press the brake pedal. For straight stops, the brake
cables must be evenly adjusted.

Lift Lever
The hydraulic lift lever (Fig. 9) has three positions:
FLOAT, TRANSPORT, and RAISE. To lower the
implement to the ground, move the lift lever forward
into the notch, which is the FLOAT position. The
FLOAT position is used for operation and also when
the machine is not in operation. To raise the
implement, pull the lift lever backward to the RAISE
position. After the implement is raised, allow the lift

Operation
When your foot is removed from the traction pedal,
the machine should stop; It must not creep in either
direction. If it does, don’t operate it until the neutral
assembly has been repaired and adjusted; refer to
Adjusting the Traction Drive for Neutral, page 30.

Power Take Off Lever
The power take-off lever (Fig. 10) has two positions:
ON (engage) and OFF (disengage). Slowly push the
power take-off lever fully forward to the ON position
to start the implement or the cutting unit blades.
Slowly, pull the lever backward to the OFF position to
stop implement operation. The only time the power
take-off lever should be in the ON position is when
the implement or cutting unit is down in operating
position.
Fuel Gauge
The fuel gauge (Fig. 10) indicates quantity of fuel
remaining in the fuel tank.
Hour Meter
The hour meter (Fig. 10) shows the accumulated
hours of engine operation.
Oil Pressure Warning Light
The oil pressure warning light (Fig. 10) glows when
oil pressure in the engine drops below a safe level. If
low oil pressure ever occurs, stop the engine and
determine the cause. Repair the damage before
starting the engine again.
Charge Indicator
Illuminates when the system charging circuit
malfunctions (Fig. 10).
Engine Coolant Temperature Warning
Light
The light illuminates and the engine shuts down when
coolant reaches an excessively high temperature
(Fig. 10).

Temperature Override Switch
Press and hold the override switch to start the engine
after a high-temperature shut down. Use it only for
emergency operation.
Glow Plug Indicator
When lit, indicates glow plugs are on (Fig. 10).
Key Switch
Three positions: OFF, ON/Preheat and START
(Fig. 10).
Throttle Control
Use the throttle (Fig. 10) to operate the engine at
different speeds. Moving the throttle forward
increases engine speed—FAST; moving it backward
decreases engine speed—SLOW. The throttle
regulates the speed of the cutter blades or other
implement components and, with the traction pedal,
controls the traction unit’s ground speed.
Seat Adjusting Lever
To adjust the standard seat, push the lever (Fig. 11)
backward and slide the seat to the desired position.
Release the lever to lock the seat in place. The
suspension seat may be adjusted forward or rearward
by pulling out the lever at the left side of the seat,
sliding the seat to the desired position, and releasing
the lever. The weight adjustment knob may be
adjusted for any operator’s comfort.

Starting/Stopping the engine
The fuel system must be bled if any of
the following situations have occurred.
A. Initial start up of a new machine.
B. The engine has ceased running due to lack of
fuel.
C. Maintenance has been performed on fuel system
components; i.e., filter replaced, separator
serviced, etc.
Refer to Bleeding the Fuel System.
1. Set the parking brake, put the power take-off
switch in the OFF position and the lift lever in
the TRANSPORT or FLOAT position. Remove
your foot from the traction pedal and make sure it
is in neutral.
2. Move the throttle control to the 1⁄2-throttle
position.
3. Turn the ignition switch to ON/Preheat position.
An automatic timer will control preheat for 10
seconds. After preheat, turn the key to the
START position. CRANK THE ENGINE FOR
NO LONGER THAN 15 SECONDS. Release the
key when the engine starts. If additional preheat
is needed, turn the key to the OFF position then
to the ON/preheat position. Repeat the process as
needed.
4. Run the engine at idle speed or partial throttle
until it warms up.
Note: Move the throttle to the 1⁄2-throttle position
when restarting a warm engine.
5. When the engine is started for the first time, or
after an engine oil change, or overhaul of the
engine, transmission or axle, operate the machine
in forward and reverse for one or two minutes.
Also operate the lift lever and power take-off
lever to assure all parts operate correctly. Turn
the power steering wheel to the left and right to
check steering response. Then shut the engine off
and check fluid levels, check for oil leaks, loose

parts and any other noticeable malfunctions.
6. To stop the engine, move the throttle control
backward to the SLOW position, move the power
take-off switch to the OFF position and turn the
ignition key to OFF. Remove the key from the
switch to prevent accidental starting.
Bleeding the Fuel System
1. Park the machine on a level surface. Make sure
the fuel tank is at least half full.
2. Unlatch and raise the hood.
3. Open the air bleed screw on the fuel injection
pump (Fig. 12).
Figure 12
1. Fuel injection pump bleed screw
4. Turn the key in the ignition switch to ON. The
electric fuel pump will begin operation, and force
air out around the air bleed screw. Leave the key
in the ON position until a solid stream of fuel
flows out around the screw. Tighten the screw
and turn the key to OFF.
Note: Normally, the engine should start after these
bleeding procedures. However, if it doesn’t, air may
be trapped between the injection pump and injectors;
refer to Bleeding Air from Injectors, page 27.
Checking the Interlock Switches
The machine has interlock switches in the electrical
system. They are designed to stop the engine when
you get off the seat while the power take-off lever is
engaged or the traction pedal is depressed. However,
you may get off the seat while the engine is running.
Although the engine will continue to run if the power

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.
DANGER
If safety interlock switches are disconnected or
damaged the machine could operate
unexpectedly causing personal injury.
• Do not tamper with the interlock switches.
• Check interlock switch operation daily
and replace any damaged switches before
operating the machine.
• Replace switches every two years or 1,000
hours, whichever occurs first.
CAUTION
Shut off the engine and wait for all moving
parts to stop before checking for oil leaks, loose
parts or other malfunctions.

take-off lever is disengaged and the traction pedal is
released, it is strongly recommended that you stop the
engine before dismounting from the seat.
To check interlock switch operation:
1. Drive the machine slowly to a large, relatively
open area. Lower the cutting unit, stop the engine
and apply the parking brake.
2. Sit on the seat. Move the power take-off lever to
the ON position. With the traction pedal in
neutral, try to start the engine. The engine should
not crank. If it does, there is a malfunction in the
interlock system that should be corrected before
beginning operation.
3. Sit on the seat. Move the power take-off lever to
OFF and depress the traction pedal. Try to start
the engine. The engine should not crank. If it
does, there is a malfunction in the interlock
system that should be corrected before beginning
operation.
4. Sit on the seat and start the engine. Disengage
the parking brake. Rise from the seat and move
the power take-off lever to ON. The engine
should stop within 2–3 seconds. If it doesn’t,
there is a malfunction in the interlock system that
should be corrected before beginning operation.
5. Engage the parking brake. Depress the traction
pedal while the engine is running and the power
take-off lever is disengaged. The engine should
stop within 2 seconds. If the engine stops, the
switch is operating correctly. If it doesn’t, there is
a malfunction in the interlock system that should
be corrected before beginning operation.
Pushing or Towing the Traction
Unit
In an emergency, the traction unit can be pushed or
towed for a very short distance. However, Toro does
not recommend this as standard procedure.
Do no push or tow the traction unit faster
than 2 to 3 MPH (3 to 4.8 km/h) because the
transmission may be damaged. If the traction unit
must be moved a considerable distance, transport it on
a truck or trailer. Whenever the traction unit is pushed
or towed, the bypass valve must be open.
1. Reach under the traction unit and turn the bypass
valve (Fig. 13) 1⁄2to 1 turn counterclockwise.
Opening the valve opens an internal passage in
the transmission, thereby bypassing transmission
oil. Because fluid is bypassed, the traction unit
can be moved without damaging the
transmission.
Figure 13
1. Bypass valve
2. Before starting the engine, close the bypass valve
by turning it clockwise until it is securely seated.
Do not exceed 5 to 8 ft.-lb. (7 to 11 N•m). Do not
start the engine when the valve is open.
Running the machine with the bypass
valve open will overheat the transmission.
Operating Characteristics
Practice driving the machine because it has a
hydrostatic transmission and its characteristics are
different than many turf maintenance machines. Some
points to consider when operating the traction unit,
cutting unit, or other implement are the transmission,
engine speed, load on the cutting blades or other
implement components, and the importance of the
brakes.
