The Safety Interlock System

Caution
If safety interlock switches are disconnected or
damaged the machine 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 machine.
Replace switches every two years regardless of
whether they are operating properly or not.
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 PTO is Disengaged.
The safety interlock system is designed to stop the engine
if:
You rise from the seat when the brake pedal is released.
You rise from the seat when the PTO is Engaged.
You shift into reverse with the PTO engaged.
Setting the KeyChoice
Operate in Reverse
An interlock feature on the tractor prevents the power take
off (PTO) from operating when backing up. If you shift into
reverse with the PTO engaged (i.e., with mower blades or
other attachment running), the engine will stop. Do not
mow in reverse unless absolutely necessary.
If you need to use the PTO while backing up, you can turn
off this interlock feature using the KeyChoice switch
located near the seat bracket (Fig. 9).
