IMPROVED NEUTRAL START CIRCUIT FOR A VEHICLE INCLUDING A POWER TAKE-OFF ASSEMBLY Abstract of the Disclosure A tractor includes a PTO clutch and is provided with a safety interlock circuit including an ignition switch having separate output terminals respectively coupled to PTO and transmission switches that must be closed, by disengaging the clutch and shifting the transmission to neutral, before the tractor can be started. A start relay is coupled for being energized only when the PTO switch is closed and it then acts to complete a current path between the transmission switch and a starter solenoid. When de-energized, the start relay acts to complete an alternate current path to the solenoid, this path containing a lamp for indicating clutch engagement and which acts to drop the voltage below that required for starting. Mechanical engagement of the PTO clutch is electrically maintained by a PTO coil coupled in parallel with the start relay and with a reset relay, the latter operating when energized to complete an alternate current path for maintaining the PTO coil energized, after the clutch is engaged and the PTO switch opens, for so long as an operator remains seated to close a normally open seat switch which functions to control a transistor that controls grounding of the reset relay.
