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.
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
The power-take-off (PTO) is Off.
The operator is seated.
The brake pedal is depressed.
The safety system is designed to stop the engine if:
You rise from the seat when the clutch/brake pedal is
released.
You rise from the seat when the PTO is Engaged.
You shift into reverse with the PTO engaged and the
operating-in-reverse interlock not deactivated.
Setting the KeyChoice Switch to
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).
