A control linkage system is disclosed for simultaneous control of an engine throttle or governor and a hydrostatic transmission from a single control pedal. The system includes unidirectional linkage means including a pair of lost motion links mounted for reciprocal movement at opposed ends of a lever rotatable in either direction by the single pedal. The lost motion links extend outwardly in the same general direction and are coupled at a common pin with the throttle control linkage through a rocker arm. Each lost motion linkage is retractable upon motion of the linkage system in one direction. A second bidirectional linkage means, including an override link, is interconnected to the pedal and a swash plate control member of the hydrostatic transmission. |
