Setting the KeyChoice
Switch to
Operate in Reverse
The interlock feature on the tractor prevents the power
take-off (PTO) from operating when you back up the
tractor. If you operate the tractor in reverse with the blades
(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 blades (PTO) while backing up, turn
off the interlock feature using the KeyChoice switch
located near the seat bracket (Fig. 12).

Danger
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 the tractor.
• Use the KeyChoice switch only if you are certain
that 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
you leave the tractor unattended.
1. Engage the blades (PTO).
2. Insert the KeyChoice key into the switch (Fig. 12).
3. Turn the KeyChoice key.
A red light on the front console (Fig. 13) turns on,
indicating that the interlock is disabled.

Testing the Safety Interlock
System
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.
Caution
Test the safety interlock system before you use the tractor
each time. If the safety interlock system does not operate as
described below, have an Authorized Service Dealer repair
the safety interlock system immediately. While sitting in
the seat, perform the following checks:
1. Set the parking brake, shift the blade control (PTO)
knob to the Engage position, and turn the ignition key
to Start: The engine should not crank.
2. Shift the blade control (PTO) knob to the Disengage
position, release the parking brake, and turn the ignition
key to Start: The engine should not crank.
3. Set the parking brake, shift the blade control (PTO)
knob to Disengage, and start the engine. While the
engine is running, release the parking brake and rise
slightly from the seat: The engine should stop.
