The Safety Interlock System

CAUTION
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.
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 neutral locked
position
The safety interlock system also is designed to stop the
engine when the traction controls are moved from the locked
position with the parking brake engaged or if you rise from
the seat when the PTO is engaged.
The hour meter has symbols to notify the user when the
interlock component is in the correct position. When the
component is in the correct position, a triangle will light up
in the corresponding square.
G009181
1. Triangles light up when the interlock components are in the
correct position
Testing the Safety Interlock System
Service Interval: Before each use or daily

system immediately.
