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 blades from rotating unless:
• The right side motion control lever is moved to the
center, un-locked position.
• The blade control switch (PTO) is pulled on.
The safety interlock system is designed to stop the
mower blades if you move or release the right side
motion control lever into the neutral lock position.
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.
1. Triangles light up when the interlock components are in the
correct position
