Using the Safety Interlock
System
Caution
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.
Replace switches every 2 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:
The clutch/brake pedal is depressed.
The blade control (PTO) lever is in the Disengage
position.
The safety interlock system stops the engine if you rise
from the seat when you release the clutch/brake pedal or
engage the blade.
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 shift the ground speed lever into Reverse
with the 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 PTO while backing up, turn off the
interlock feature using the KeyChoice switch located near
the seat bracket (Fig. 10).
