Using The Safety Interlock System - Toro 71428 Operator's Manual

Using the Safety Interlock
System
Caution
If the safety interlock switches are disconnected or
damaged, the tractor could operate unexpectedly,
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the tractor.
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
• You are sitting on the seat.
• The brake pedal is depressed.
• The blade control (PTO) is in the Disengage position.
The safety interlock system is designed to stop the engine if
you do the following:
• You rise from the seat when the brake pedal is released.
• You rise from the seat while the blade control (PTO) is
in the Engage position.
• You shift into reverse while the blade control (PTO) is
in the Engage position.
Setting the KeyChoice
Operate in Reverse
An interlock feature on the tractor prevents the power
take-off (PTO) from operating when you back up the
tractor. If you shift the ground speed switch into Reverse
with the PTO engaged (i.e., with the mower blades or other
attachment running), the engine will stop. Do not mow in
reverse unless it is absolutely necessary.
If you need to use the blade control (PTO) while backing
up, turn off the interlock feature using the KeyChoice
switch located near the seat bracket (Fig. 10).

Switch to
You could back over a child or bystander while the
mower blades or other attachment is engaged and
cause serious injury or death.
• Do not mow in reverse unless it is absolutely
necessary.
• Do not insert the KeyChoice key unless it is
absolutely necessary.
• Always look backward and down before
backing up.
• Use the KeyChoice switch only if you are certain
no children or other bystanders will enter the
mowing area.
• Be very observant after deactivating the
interlock because the sound of the engine may
prevent you from noticing that a child or
bystander has entered the work area.
• Always remove both the ignition and KeyChoice
keys and put them in a safe place out of the
reach of children or unauthorized users when
leaving the tractor unattended.
