Abstract
A mower control linkage having a double ended dead man control lever, left and right steering control levers, and a linkage interconnecting said levers with left and right transmission mechanisms. The linkage has swingable left and right are members that adjust the transmission mechanisms between braked, clutch disengaged and driven modes. The arm members arm connected to the dead man control lever via a lost motion coupling and are each linked with respective steering control levers. As the dead man control lever is depressed, both arm members are placed in a driven mode, and either steering control lever can then be depressed to shift the respective arm member to its braked mode to execute a turn about that wheel.
