Abstract:
An interlock circuit is provided for a vehicle having a first PTO shaft and an optional second PTO shaft. When the optional PTO is installed, a standard seat switch utilized with the base interlock circuit is connected to an additional relay to put the interlock into a potential defeat mode as soon as the operator leaves the seat, provided the vehicle parking brake is engaged and a mechanical selector lever is in a position wherein the optional PTO only is selected. Other interlock functions remain unaffected whether or not the optional PTO is installed.
