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 power take off (PTO) is off
The hydro control pedal is in the neutral position.
The safety interlock system is designed to stop the power
take off (PTO) if:
You rise from the seat when the brake pedal is released
You rise from the seat when the power take off (PTO)
is on.
You move the hydro control pedal out of the neutral
position when the parking brake is engaged.
You shift into reverse with the power take off (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 PTO will
disengage. 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. 7).

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. 7).
