PTO Switch
The PTO switch provides battery voltage from the ignition switch to the PTO clutch.
As part of the safety interlock system, the PTO switch will prevent the engine from cranking/starting when in the
ON position by preventing the starter solenoid from grounding through the kill relay.
NOTE: The engine will not crank over when the PTO switch is in the ON position.
The PTO Switch provides battery voltage from the ignition switch to the parking brake switch and the neutral
switches as part of the safety interlock system.
