properly. Do not operate unless they are functioning
properly.
3
Operation
• Never run an engine in an enclosed area.
• Only operate in good light, keeping away from holes
and hidden hazards.
• Be sure all drives are in neutral and parking brake is
engaged before starting the engine. Only start the
engine from the operator’s position.
• Slow down and use extra care on hillsides. Be sure to
travel in the recommended direction on hillsides. Turf
conditions can affect the machine’s stability.
• Slow down and use caution when making turns and
when changing directions on slopes.
• Never operate with the guards not securely in place.
Be sure all interlocks are attached, adjusted properly,
and functioning property.
• Do not change the engine governor setting or
overspeed the engine.
• Stop on level ground, lower implements, disengage the
auxiliary hydraulics, engage parking brake, shut off
the engine before leaving the operator’s position for
any reason.
• Keep hands and feet away from moving attachments.
• Look behind and down before backing up to be sure of
a clear path.
• Never carry passengers and keep pets and bystanders
away.
• Slow down and use caution when making turns and
crossing roads and sidewalks.
• Do not operate the machine under the influence of
alcohol or drugs
• Use care when loading or unloading the machine into a
trailer or truck
• Use care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.
• Read all attachment manuals.
• Ensure that the area is clear of other people before
operating the traction unit. Stop the traction unit if
anyone enters the area.
• 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.
• Never jerk the controls; use a steady motion.
• Watch for traffic when operating near or crossing
roadways.
• 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 14, and those in the attachment
operator’s manual. See also the slope chart on page 7.
• 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 14, 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.
4
• 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.
• 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, setting
the parking brake, and chocking the tracks.
Maintenance and Storage
• Disengage the auxiliary hydraulics, lower the
attachment, set the parking brake, stop the engine, and
remove the key. Wait for all movement to stop before
adjusting, cleaning, or repairing.
• Clean debris from attachments, drives, mufflers, and
engine to help prevent fires. Clean up oil or fuel
spillage.
• Let the engine cool before storing and do not store
near flame.
• Do not store fuel near flames or drain indoors.
• Park the machine on level ground. Never allow
untrained personnel to service the machine.
• Use jack stands to support components when required.
• Carefully release pressure from components with
stored energy.
• Disconnect the battery or remove the spark plug wires
before making any repairs. Disconnect the negative
terminal first and the positive last. Reconnect positive
first and negative last.
• 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 the charger before
connecting or disconnecting it from the battery. Wear
protective clothing and use insulated tools.
• 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.
• Secure the loader arm valve with the loader valve lock
anytime you need to stop the machine with the loader
arms raised.
• Keep nuts and bolts tight. Keep equipment in good
condition.
• Never tamper with safety devices.
• 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.

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.
