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.
• 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 controls; use a steady motion.
• Watch for traffic when operating near or crossing
roadways.
• 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 traction
unit loses 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.
4
• 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.
• 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.

Attachments
Many attachments are available for use with the traction
unit. These attachments allow you to to perform many
different functions with the traction unit such as hauling
materials, digging holes, grading, and more. Contact your
Toro dealer for a list of all approved attachments and
accessories.
Important Use only Toro-approved attachments.
Stability Data
The following tables list the maximum slope recommended for the traction unit in the positions listed in the tables. Slopes
over the listed degree may cause the traction unit to become unstable. The data in the tables assume that the loader arms
are fully lowered; raised arms may affect the stability.
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 stability ratings of the
attachment. Example: If the attachment installed on a TX 420 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 following table for the TX 420 traction unit.

Danger
Add the correct amount of gas stabilizer/conditioner to the
gas.
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.
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.
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.
3. Clean around the fuel tank cap and remove it.
4. Add unleaded gasoline to the fuel tank, until the level
is just 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.
Checking the Oil Level
1. Park the traction unit on a level surface, lower the
loader arms, and stop the engine.

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.
• 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.

Key Switch
Loader Arm/Attachment Tilt Lever
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 Lever
Before starting a cold engine, move the choke lever
forward. After the engine starts, regulate the choke to
keep the engine running smoothly. As soon as possible,
move the choke lever all the way rearward.
Note: 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. 9).
To tilt the attachment forward, slowly move the lever to
the right (Fig. 10).
To tilt the attachment rearward, slowly move the lever to
the left (Fig. 10).
To lower the loader arms, slowly move the lever forward
