The Safety Interlock System
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 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. 10).
Danger
You could back over a child or bystander while the
mower blade(s) or other attachment is engaged
and cause serious injury or death.
Do not mow in reverse unless 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 unit unattended.
1. Engage the PTO.
2. Insert the KeyChoice key into the switch (Fig. 10).
