NEUTRAL START AND PARK BRAKE SAFETY INTERLOCK CIRCUITRY FOR A TRACTOR Abstract of the Disclosure Electric control circuitry is provided for preventing a tractor engine from being started with the tractor transmission or power take-off engaged and for preventing the tractor from being driven with the park brake engaged. The control circuitry includes normally open power take-off and transmission condition sensing switches connected in series with each other and a starting solenoid and thus defining a portion of a starting circuit. These two switches in the starting circuit are respec- tively held closed only when a power take-off control lever is in a clutch-disengage position and the transmission shift lever is in a neutral position. The control circuitry also includes a second normally open transmission condition sensing switch connected in parallel with a normally open park brake condition sensing switch, these two switches being in series with the ignition coil and thus defining a portion of an ignition circuit. Also, these two switches are respectively held closed only when the transmission shift lever is in its neutral position and a brake pedal locking pawl is in a pedal-release position.
