Checking Interlock Switches
The purpose of the interlock switches is to prevent
the engine from cranking or starting unless the
traction pedal is in NEUTRAL, the Enable/Disable
switch is in DISABLE and the Lower Mow/Raise

engine will stop when the traction pedal is
depressed with operator off the seat or when
parking brake is engaged.
CAUTION
THE INTERLOCK SWITCHES ARE FOR THE
PROTECTION OF THE OPERATOR AND
BYSTANDERS, AND TO ENSURE CORRECT
OPERATION OF THE MACHINE, SO DO NOT
