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 mower
from starting unless:
•
The blade control knob (PTO) is pushed off.
•

with the mower engaged and/or the speed control is out
of neutral.
•
The speed control lever is shifted out of neutral without
holding OPC levers or with the brake engaged.
•
The blade control knob (PTO) is pulled up without
holding the OPC levers.

machine may move forward and cause personal
injury or property damage.

Ensure no one is standing in front of the
machine while performing the safety interlock
test.
