Using the Safety-Interlock
System
CAUTION
If the 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 parking brake is engaged.
•
The blade-control switch (PTO) is disengaged.
•
The motion-control levers are in the N
position.
The safety-interlock system also is designed to stop the
engine when you move the traction controls from the locked
position with the parking brake engaged or if you rise from
the seat when the PTO is engaged.
