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
mower from starting unless:
The blade control knob (PTO) is pushed off.
The speed control lever is in neutral.
The safety interlock system is designed to kill the engine
when:
The Operator Presence Control (OPC) levers are
released.
The speed control lever is shifted out of neutral without
holding OPC levers.
The blade control knob (PTO) is pulled up without
holding the OPC levers.
Testing the Safety Interlock System
Test the safety interlock system before you use the machine
each time. If the safety system does not operate as
described, have an Authorized Service Dealer repair the
safety system immediately.
1. Set the neutral locks and place speed control lever in
neutral. Start the engine; refer to Starting and Stopping
the Engine, page 20.
2. Without holding the Operator Presence Control (OPC)
levers, pull the blade control knob (PTO) up. The
engine should kill.
