A control shaft is coupled for oscillating a pump swash plate of a reversible hydrostatic transmission in opposite directions from a neutral position and linked to a control arm that is fixed to the control shaft is a manual control lever that is moveable to opposite sides of a neutral position to respectively effect different forward and reverse transmission driving speeds. The control arm includes a roller at one end which is received within a specially shaped opening provided in a cam plate that is linked to the brake pedal of the tractor such that a cam surface of the cam plate opening acts on the control arm roller to simultaneously return the transmission swash plate and control lever to their respective neutral positions. A neutralizing assist includes a roller- carrying arm that is biased into contact with an elongate cam surface carried by a projection of the control arm and being formed arcuately about the axis of the control shaft. The cam surface has a V-notch formed intermediate of its opposite ends and a spring acts to keep the roller of the roller-carrying arm in contact with the cam surface. The V-notch is located such that the roller will move thereinto to force the control arm to move to its neutral position to precisely locate the transmission in its neutral position when the control lever is in its neutral position.
