ABSTRACT:
A vehicular control mechanism is known that incorporates a steering assembly swingable about an upstanding axis in either direction from a central NEUTRAL position. Even if the transmission is not powerably driving an associated cross drive mechanism the angular displacement of the steering assembly away from NEUTRAL could cause an input to the cross drive and an undesirable movement of the vehicle under some circumstances. To obviate this, an indexing device is provided that is responsive to the movement of an actuating lever pivotally mounted on a steering assembly between BRAKE-OFF and BRAKE-ON positions. The vehicle frame defines an indexing pocket, and an elongate locking element is reciprocally mounted on the steering assembly and interconnectable with the pocket when the steering assembly is angularly positioned in NEUTRAL. The operator is quickly aware that the steering assembly is displaced from NEUTRAL when he is prevented from moving the actuating lever to the BRAKE-ON position by the indexing device. A microswitch is also activated to allow restarting of an engine starting circuit when the actuating lever is moved to the BRAKE-ON position.
