A control for controlling the operation of a vehicle drive having speed control apparatus including a movable control element for causing the speed of the drive to vary in accordance with the positioning of the control element. The control element may be moved by means of a manually operable speed lever. A manually operable range selector lever is provided for actuating an adjusting apparatus for causing the amount of movement of the control element caused by a movement of the speed lever to be selectively varied. The adjusting apparatus may include a pair of cams, an actuator apparatus, movable selectively against the camming surfaces of either of the cams as a function of the movement of the speed lever. The cams are connected to the control element for providing resultingly a variable amount of movement of the control element selectively in either of the reverse or forward directions.
