A control linkage for controlling the speed and direction of a hydrostatic transmission in a lawn and garden tractor. A directional control arm, coupled to a dash mounted direction and speed control lever, pivots relative to the hydrostatic transmission in response to movement of the direction and speed control lever. A cam roller on the directional control arm engages a cam plate mounted on the control input shaft of the hydrostatic transmission so as to rotate the control input shaft in response to movement of the direction and speed control lever. A detent adjacent the transmission and engaging the cam plate fixes the position of the cam plate to eliminate backlash and avoid vehicle "creep" when the direction and speed control lever is placed in "neutral." An additional cam, responsive to engagement of a vehicle clutch/brake system automatically places the transmission in "neutral" when the clutch/brake system is engaged.
A control linkage for controlling the speed and direction of a vehicular hydrostatic transmission of the type having a rotatable control input shaft, said control linkage comprising:
