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.
• Wear long pants and substantial shoes. Wearing safety
glasses, safety shoes, hearing protection, and a hard
hat are advisable and 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.
• Do not place your feet under the platform.
• 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, and
remove the key before dismounting.
3
• Do not exceed the rated operating capacity, as the
traction unit may become unstable which may result in
loss of control.
• 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.
• Do not carry a load with the arms raised. Always carry
loads close to the ground. Do not step off of the
platform with the load raised.
• 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.
• 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.
• Do not operate the traction unit with any of the covers
or guards removed.
• 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.
• Removing an attachment on a slope will make the rear
of the traction unit heavy. Refer to the Stability Data
section, page 12, 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 slow speed on slopes. Before starting the engine,
put the pump selector lever in the slow (turtle) position
so that you will not have to stop or shift while on the
slope.
• Follow the recommendations in the attachment
manuals for the use of counterweights to improve
stability.
• 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 tires 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 wheel goes over the edge of a cliff or ditch, or
if an edge caves in.
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 12, and those in the attachment
operator’s manual. See also the slope chart on
page 6.
• 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.
• 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
chocking the wheels.
• Do not try to stabilize the traction unit by putting your
foot on the ground.
Children
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.
4
• Before and while backing, look behind and down for
small children.
• Battery gases can explode. Keep cigarettes, sparks and
flames away from the battery.
• 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 locks
included with traction unit.
• 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 your body and hands away from pin hole leaks
or nozzles that eject high pressure hydraulic fluid. Use
cardboard or paper to find hydraulic leaks. Hydraulic
fluid escaping under pressure can penetrate skin and
cause injury requiring surgery within a few hours by a
qualified surgeon or gangrene may result.
• 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 furnace.
• Never fill a container while it is inside a vehicle,
trunk, pick–up bed, or any surface other than the
ground.
• Keep container nozzle in contact with the tank
during filling.
• Stop and inspect the equipment if you strike an object.
Make any necessary repairs before restarting.
• Use only genuine replacement parts to ensure that
original standards are maintained.

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 and that the factory installed tires are on the traction unit, inflated to the recommended pressure; raised
arms and other tire types or pressure may affect the stability.
Maximum Recommended Slope
when Operating with:
Front UphillRear UphillSide Uphill
Configuration
Traction unit without attachment8°20°17°
Traction unit with counterweight, without attachment5°21°17°
Traction unit with an attachment rated with one of the following
stability ratings for each slope position:*
A25°25°20°
B18°19°17°
C15°16°14°
D10°10°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. Unless otherwise specified in the attachment manual, assume that the listed ratings are for use without the
counterweight.
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 18° slope, rearward up a 10° slope, or sideways on a 14° slope,
as listed in the above table.

Before Operating
Before operating, check the fuel and oil level, remove
debris from the traction unit, and check the tire pressure.
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
Danger
Important Never 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.
Important Never use fuel additives containing
methanol or ethanol.
Filling the Fuel Tank
1. Park the traction unit on a level surface, lower the
loader arms, and stop the engine.
2. Remove the key and allow the engine to cool.
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• 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 in. (6 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.
• 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.
Use unleaded regular gasoline (87 pump octane
minimum). Leaded regular gasoline may be used if
unleaded regular is not available.
3. Clean around the fuel tank cap and remove it.
4. Add unleaded regular gasoline the fuel tank, until the
level is 1/4 to 1/2 in. (6 to 13 mm) below the bottom
of the filler neck.
Important This space in the tank allows gasoline to
expand. Do not fill the fuel tank completely full.
5. Install the fuel tank cap securely.
6. Wipe up any gasoline that may have spilled.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
• Keeps gasoline fresh during storage of 90 days or less.
For longer storage, drain the fuel tank.
• 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.
Checking the Oil Level
1. Park the traction unit on a level surface, lower the
loader arms, and stop the engine.
2. Remove the key and allow the engine to cool.
3. Clean around the oil dipstick (Fig. 5).
4. Pull out the dipstick and wipe the metal end clean
(Fig. 5).
13
5. Slide the dipstick fully into the dipstick tube (Fig. 5).
6. Pull the dipstick out and look at the metal end.
7. If the oil level is low, clean around the oil filler cap
and remove the cap (Fig. 5).
8. Slowly pour only enough oil into the valve cover to
raise the level to the F (full) mark.
Important Do not overfill the crankcase with oil
because the engine may be damaged.
9. Replace the filler cap and dipstick.

Important Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or cooling
shrouds removed, will result in engine damage from
overheating.
1. Park the traction unit on a level surface, raise the
loader arms, and install the cylinder locks; refer to
Using the Cylinder Locks, page 18.
2. Stop the engine and remove the key.
3. Clean any debris from the grill before each use and/or
during use, if required.
2. Park the traction unit on a level surface, raise the
loader arms, and install the cylinder locks; refer to
Using the Cylinder Locks, page 18.
3. Stop the engine and remove the key.

proper level.
7. Install the cap on the filler neck.
8. Remove and store the cylinder locks (refer to Using
the Cylinder Locks, page 18) and lower the loader
arms.
4. Wipe away debris from the air cleaner before each use
and/or during use, if required.
5. Clean any debris build–up on the engine with a brush
or blower before each use.
Important It is preferable to blow dirt out, rather than
washing it out. If water is used, keep it away from
electrical items and hydraulic valves. Do not use a
high-pressure washer. High–pressure washing can
damage the electrical system and hydraulic valves or
deplete grease.
Tire pressure
Maintain the air pressure in the tires as specified. Check
the tires when they are cold to get the most accurate
reading.
Pressure: 15–20 psi
Note: Use a lower tire pressure (15 psi) when operating in
sandy soil conditions to provide better traction in the loose
soil.

Warning
If you move the speed selector lever while the
traction unit is in motion, the traction unit will
either stop suddenly or accelerate quickly. If you
operate the traction unit with the speed selector
lever in an intermediate position, the traction unit
will operate erratically and may be damaged. You
could lose control of the traction unit and injure
bystanders or yourself.
• Do not move the speed selector lever when the
traction unit is in motion.
• Do not operate the traction unit when the speed
selector is in any intermediate position (i.e., any
position other than fully forward or fully
rearward).
Hour Meter
The hour meter displays the number of hours of operation
that have been logged on the traction unit.
After 50 hours and then every 100 hours thereafter (that is
at 150, 250, 350, etc.) the screen displays CHG OIL to
remind you to change the oil. After every 100 hours, the
screen displays SVC to remind you to perform the other
maintenance procedures based on a 100, 200, or 400 hour
schedule. These reminders come on starting three hours
prior to the service interval time and flash at regular
intervals for six hours.

• Move the flow divider control to the twelve o’clock
position to provide maximum speed to the traction unit
hydraulics.
Use this setting for fast operation of the traction unit.
• Move the flow divider control between the twelve
o’clock and nine o’clock positions to slow the traction
unit hydraulics and fine tune the speed.
Use a setting in this range with attachments with
hydraulics where you need to both run the attachment
and move the traction unit hydraulics, such as the
auger, boring unit, hydraulic blade, and tiller.
• Move the control to the nine o’clock position to
transfer all hydraulic flow to the auxiliary hydraulics
of the attachment.
In this setting, the traction unit hydraulics will not
work. Use this setting with hydraulic attachments that
do not required the traction unit hydraulics. There are
currently no attachments that require the nine o’clock
position; however, the trencher does work best if you
set it close to nine o’clock so that the traction unit will
creep slowly when trenching.

circuit from the auxiliary hydraulics for powering
attachments; however, the two systems share the same
hydraulic pumps. Using the flow divider control (Fig.
10), you can vary the speed of the traction unit hydraulics
by diverting hydraulic flow to the auxiliary hydraulics
circuit. The flow divider allows you to divide the flow of
fluid in varying degrees to slow the traction unit. Thus,
the more hydraulic flow you divert to the auxiliary
hydraulics, the slower the traction unit hydraulics will
move.
Note: The flow divider control can be fixed in place by
turning the knob on the control clockwise until it contacts
the dial (Fig. 10).
Starting and Stopping the
Engine
Starting the Engine
1. Stand on the platform.
2. Move the auxiliary hydraulics valve lever to neutral.
3. Move the throttle lever midway between slow (turtle)
and fast (rabbit) positions.
4. Move the choke lever fully forward before starting a
cold engine.
Note: A warm or hot engine may not require choking.
17
5. 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.
6. After the engine starts, gradually move the choke to
rearward. If the engine stalls or hesitates, move the
choke forward again until the engine warms up.
7. 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 around 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: The farther you move the traction control levers in
either direction, the faster the traction unit will move in
that direction.
Stopping the Traction Unit
To stop the traction unit, move the traction control levers
to neutral and the throttle lever to slow (turtle), lower
loader arms to the ground, and turn the ignition key off to
stop the engine. Remove the key.
Caution
A child or untrained bystander could attempt to
operate the traction unit and be injured.
Remove the key from the switch when leaving the
traction unit, even if just for a few seconds.
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.
Driving Forward or Backward
The throttle control regulates the engine speed as
measured in rpm (revolutions per minute). Place the
throttle lever in the fast (rabbit) position for best
performance.
Note: Throttle position can be utilized to operate at slower
speeds.
To drive the traction unit, complete the following actions
as necessary:
• To move forward, move the traction control levers
forward.
