The Safety Interlock System

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 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.
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.
While testing the safety interlock system, the
machine may move forward and cause personal
injury or property damage.
• Perform the safety interlock test in an open
area.
• Ensure no one is standing in front of
the machine while performing the safety
interlock test.
