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.

The safety interlock system is designed to prevent the mower
blades from rotating unless:

The control bail is depressed.
•
The power take off switch (PTO) is pulled on.
The safety interlock system is designed to stop the mower
blades if you release the blade control bail.
