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 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.
