ABSTRACT:
A reciprocal control member for a transmission is pivotally connected to a rotatable sleeve for selectively placing the transmission in its neutral, forward or reverse modes of operation. A hand lever is connected to the sleeve to rotate it to place the transmission in a selected mode of operation and to simultaneously control the speed thereof. A foot pedal is adapted to be depressed to control the output speed of the transmission by overriding the first input control when the first input control is either in its forward or reverse position of operation. The foot pedal is connected to the sleeve by a pair of pin and slot connections for inducing rotation of the sleeve upon movement of the foot pedal in either direction.
