Safety
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
This product is capable of amputating hands and feet.
Always follow all safety instructions to avoid serious
injury or death.
POTENTIAL HAZARD
•Engine exhaust contains carbon monoxide,
which is an odorless, deadly poison.
WHAT CAN HAPPEN
•Carbon monoxide can kill you and is also
known to the State of California to cause
birth defects.
HOW TO AVOID THE HAZARD
•Do not run engine indoors or in an enclosed
area.
Because in some areas there are local, state, or federal
regulations requiring that a spark-arrester be used on
engines, a spark-arrester is available as an option for
the traction unit. If a spark-arrester is required,
contact your Toro dealer. Genuine Toro approved
spark-arresters are approved by the USDA Forestry
Service. It is a violation of the State of California
PRC Section 4442 to use or operate the engine on any
forest-covered, brush-covered, or grass-covered land,
unless the engine is equipped with a spark-arrester,
maintained in working order, or the engine is
constricted, equipped, and maintained for the
prevention of fire.
General Operation
•Read, understand, and follow all instructions in
the operator’s manual, in the video, and on the
traction unit before starting. Also, read all
attachment manuals where supplied.
•Allow only responsible adults who are familiar
with the instructions to operate the traction unit.
•Always wear long pants, safety glasses, safety
shoes, hearing protection, and a hard hat when
operating the traction unit and any of its
attachments. Other personal protective
equipment may be required by some local
ordinances and insurance regulations.
•Ensure that the area is clear of other people
before operating the traction unit. Stop the
traction unit if anyone enters the area.
•Never carry passengers on attachments or on the
traction unit.
•Always look down and behind before and while
backing.
•Slow down before turning. Sharp turns on any
terrain may cause loss of control.
•Never leave a running traction unit unattended.
Always lower the loader arms, stop the engine,
set the parking brake, and remove the key before
leaving.
•Do not exceed the rated operating capacity, as
the traction unit may become unstable which
may result in loss of control.
•Do not carry a load with the arms raised. Always
carry loads close to the ground.
•Do not over-load the attachment and always
keep the load level when raising the loader arms.
Logs, boards, and other items could roll down
the loader arms, injuring you.

Safety
3
•Never jerk the control levers; use a steady
motion.
•Keep your hands, feet, hair, and loose clothing
away from any moving parts.
•Operate only in daylight or good artificial light.
•Do not operate the traction unit while under the
influence of alcohol or drugs.
•Watch for traffic when operating near or crossing
roadways.
•Use extra care when loading or unloading the
traction unit onto a trailer or truck.
•Do not touch parts which may be hot from
operation. Allow them to cool before attempting
to maintain, adjust, or service.
•Check for overhead clearances (i.e. branches,
doorways, electrical wires) before driving under
any objects and do not contact them.
•Before digging, have the area marked for
underground utilities, and do not dig in marked
areas.
•Locate the pinch point areas marked on the
traction unit and attachments and keep hands and
feet away from these areas.
Slope Operation
Slopes are a major factor related to loss-of-control
and tip-over accidents, which can result in severe
injury or death. All slopes require extra caution.
•Do not operate the traction unit on hillsides or
slopes exceeding the angles recommended in the
Stability Data section, page 10, and those in the
attachment operator’s manual. See also the
slope chart on page 5.
•Operate up and down slopes with the heavy
end of the traction unit uphill. Weight
distribution changes. An empty bucket will make
the rear of the traction unit the heavy end, and a
full bucket will make the front of the traction
unit the heavy end. Most other attachments will
make the front of traction unit the heavy end.
•Raising the loader arms on a slope will affect the
stability of the machine. Whenever possible,
keep the loader arms in the lowered position
when on slopes.
•Removing an attachment on a slope will make
the rear of the traction unit heavy. Refer to the
Stability Data section, page 10, to determine
whether the attachment can be safely removed
on the slope.
•Remove obstacles such as rocks, tree limbs, etc.
from the work area. Watch for holes, ruts, or
bumps, as uneven terrain could overturn the
traction unit. Tall grass can hide obstacles.
•Use only Toro-approved attachments.
Attachments can change the stability and the
operating characteristics of the traction unit.
Warranty may be voided if used with
unapproved attachments.
•Keep all movements on slopes slow and gradual.
Do not make sudden changes in speed or
direction.
•Avoid starting or stopping on a slope. If the
tracks lose traction, proceed slowly, straight
down the slope.
•Avoid turning on slopes. If you must turn, turn
slowly and keep the heavy end of the traction
unit uphill.
•Do not operate near drop-offs, ditches, or
embankments. The traction unit could suddenly
turn over if a track goes over the edge of a cliff
or ditch, or if an edge caves in.
•Do not operate on wet grass. Reduced traction
could cause sliding.
•Do not park the traction unit on a hillside or
slope without lowering the attachment to the
ground and setting the parking brake.

Tragic accidents can occur if the operator is not alert
to the presence of children. Children are often
attracted to the traction unit and the work activity.
Never assume that children will remain where you
last saw them.
•Keep children out of the work area and under the
watchful care of another responsible adult.
•Be alert and turn the traction unit off if children
enter the area.
•Before and while backing, look behind and down
for small children.
•Never carry children. They may fall off and be
seriously injured or interfere with safe traction
unit operation.
•Never allow children to operate the traction unit.
•Use extra care when approaching blind corners,
shrubs, trees, the end of a fence, or other objects
that may obscure vision.
Service
•Stop the engine and disconnect the spark plug
wires before performing any service, repairs,
maintenance, or adjustments.
•If any maintenance or repair requires the loader
arms to be in the raised position, secure the arms
in the raised position with the hydraulic cylinder
lock.
•Never run a traction unit inside a closed area.
•Keep nuts and bolts tight. Keep equipment in
good condition.
•Never tamper with safety devices. Check safety
systems for proper operation before each use.
•Keep the traction unit free of grass, leaves, or
other debris build-up. Clean up oil or fuel
spillage. Allow the traction unit to cool before
storing.
•Use extra care when handling gasoline and other
fuels. They are flammable and vapors are
explosive.
•Use only an approved container.
•Never remove the gas cap or add fuel when
the engine is running. Allow the engine to
cool before refueling. Do not smoke.
•Never refuel the traction unit indoors.
•Never store the traction unit or fuel
container inside where there is an open
flame, such as near a water heater or

Stability Data
The following table lists the maximum slope recommended for the traction unit in the positions listed in the
table. Slopes over the listed degree may cause the traction unit to become unstable. The data in the table
assumes that the loader arms are fully lowered; raised arms may affect the stability.
Maximum Recommended Slope
when Operating with:
Configuration
Front Uphill Rear Uphill Side Uphill
Traction unit without attachment 11°21°19°
Traction unit with an attachment rated with one of the following
stability ratings for each slope position:*
A25°25°20°
B20°20°18°
C17°17°14°
D10°12°9°
E5°5°5°
* In each attachment manual is a set of three stability ratings, one for each hill position. To determine the
maximum slope you can traverse with the attachment installed, find the degree of slope that corresponds to the
stabilities ratings of the attachment.
Example: If the attachment installed on the traction unit has a Front Uphill rating of B, a Rear Uphill rating of
D, and a Side Uphill rating of C, then you could drive forward up a 20°slope, rearward up a 12°slope, or
sideways on a 14°slope, as listed in the above table.

11
Before Operating
Before operating, check the fuel and oil level, and
remove debris from the traction unit. Also, ensure
that the area is clear of people and debris. You should
also know and have marked the locations of all utility
lines.
Adding Fuel
POTENTIAL HAZARD
•When fueling, under certain circumstances,
a static charge can develop, igniting the
gasoline.
WHAT CAN HAPPEN
•A fire or explosion from gasoline can burn
you, others, and cause property damage.
HOW TO AVOID THE HAZARD
•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.
POTENTIAL HAZARD
•In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
•A fire or explosion from gasoline can burn
you, others, and cause property damage.
HOW TO AVOID THE HAZARD
•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 1/4” to 1/2” (6 mm to 13 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.
Use unleaded gasoline (85 pump octane minimum).
Leaded, regular gasoline may be used if unleaded is
not available.
IMPORTANT: Do not use methanol, gasoline
containing methanol, or gasohol containing
more than 10% ethanol because the fuel
system could be damaged. Do not mix oil with
gasoline.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the traction unit to
provide the following benefits:
•Keeps gasoline fresh during storage of 90 days
or less. For longer storage it is recommended
that the fuel tank be drained.

Check Before Operating
12
•Cleans the engine while it runs
•Eliminates gum-like varnish buildup in the fuel
system, which causes hard starting
IMPORTANT: Do not use fuel additives
containing methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner
to the gas.
Note: A fuel stabilizer/conditioner is most
effective when mixed with fresh
gasoline. To minimize the chance of
varnish deposits in the fuel system, use
fuel stabilizer at all times.

Key Switch
The key switch, used to start and stop the engine, has
three positions: off, run, and start.
To start the engine, rotate the key to the start position.
Release the key when engine starts and it will move
automatically to the run position.
To stop the engine, rotate the key to the off position.
Throttle Lever
Move the control forward to increase the engine
speed and rearward to decrease speed.
Choke Knob
Before starting a cold engine, pull the choke knob
out. After the engine starts, regulate the choke to
keep the engine running smoothly. As soon as
possible, push the choke knob in as far as possible. A
warm engine requires little or no choking.
Reference Bar
When driving the traction unit, use the reference bar
as a handle and a leverage point for controlling the
traction control and the auxiliary hydraulics lever. To
ensure smooth, controlled operation, do not take both
hands off of the reference bar while operating the
traction unit.
Traction Control
To move forward, move the traction control forward.
To move rearward, move the traction control rearward
(Fig. 8).
To turn, rotate the traction control in the desired
direction (Fig. 8).
The farther you move the traction control in any
direction, the faster the traction unit will move in that
direction.
To stop, release the traction control.

Loader Arm/Attachment Tilt Lever
To tilt the attachment forward, slowly move the lever
to the right (Fig. 9).

Operation
16
To tilt the attachment rearward, slowly move the lever
to the left (Fig. 9).
To lower the loader arms, slowly move the lever
forward (Fig. 9).
To raise the loader arms, slowly move the lever
rearward (Fig. 9).
You can also push the lever fully forward into a
detent position (Fig. 9) to release the loader arms so
that the attachment rests on the ground. This allows
attachments such as the leveler and the hydraulic
blade to follow the contours of the ground (i.e., float)
when grading.

5. Detent (Float) position
By moving the lever to an intermediate position (such
as, forward and left), you can move the loader arms
and tilt the attachment at the same time.
Auxiliary Hydraulics Lever
To operate a hydraulic attachment in the forward
direction, rotate the auxiliary hydraulics lever
rearward and pull it down to the reference bar
(Fig. 10, number 2).
To operate a hydraulic attachment in reverse
direction, rotate the hydraulics lever rearward, then
move it left into the upper slot (Fig. 10, number 3).
To operate the auxiliary hydraulics in the reverse
direction using a detent position, rotate the lever
rearward, then move it left into the middle slot
(Fig. 10, Number 4). Only use the detent position for
attachments that require it for operation, such as the
Cement Bowl. To determine if an attachment requires
the detent position, refer to the attachment operator’s
manual.
If you release the lever while in either the forward
position or upper reverse position, the lever will
automatically return to the neutral position
(Fig. 10, Number 1). If it is in the detent position, it
will remain there until you pull it out of the slot.

Parking Brake Lever
To set the parking brake, pull the brake lever rearward
and then push it to the left, hooking it into the notch
(Fig. 11).
Note: The traction unit may roll slightly
before the brakes engage in the drive
sprocket.

To release the brake, pull the lever rearward and right,
out of the notch, and then push it forward.
Fuel Gauge
This gauge measures the amount of fuel in the fuel
tank.
Hydraulic Oil Temperature Light
If the hydraulic oil gets too hot, this light illuminates
and an audible alarm sounds. If this happens, stop
the engine and allow the traction unit to cool.
Hour Meter
This meter displays the number of hours that the
traction unit has run since it was built.
Starting and Stopping the
Engine
Starting the Engine
1. Ensure that the auxiliary hydraulics lever is in
neutral.
2. Move the throttle lever midway between slow
(turtle) and fast (rabbit) positions.
3. Pull out the choke lever if you are starting a cold
engine.
Note: A warm or hot engine may not require
choking.
4. Turn the ignition key to the start position. When
the engines starts, release the key.
IMPORTANT: Do not engage the starter for
more than 10 seconds at a time. If the engine
fails to start, allow a 30 second cool-down
period between attempts. Failure to follow
these instructions can burn out the starter
motor.
5. After the engine starts, gradually push the choke
inward. If the engine stalls or hesitates, pull the
choke out again until the engine warms up.
6. Move the throttle lever to desired setting.
IMPORTANT: If the engine is run at high
speeds when the hydraulic system is cold (i.e.,
when the ambient air temperature is near
freezing or lower), hydraulic system damage
could occur. When starting the engine in cold
conditions, allow the engine to run in the
middle throttle position for 2 to 5 minutes
before moving the throttle to fast (rabbit).
Note: If outdoor temperature is below
freezing, store the traction unit in a
garage to keep it warmer and aid in
starting.
Stopping the Engine
1. Move the throttle lever to the slow (turtle)
position.
2. Lower the loader arms to the ground.
3. Turn the ignition key off.
Note: If the engine has been working hard or
is hot, let it idle for a minute before
turning the ignition key off. This helps
cool the engine before it is stopped. In
an emergency, the engine may be
stopped immediately.
