Understanding the Safety-Interlock
System
WARNING
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.
The safety-interlock system is designed to prevent the engine
from starting unless:
•
The blades are disengaged.

The motion-control levers are in the park position.
The safety-interlock system also is designed to stop the engine
whenever the control levers are out of the park position and
you rise from the seat.
