Abstract
A steering mechanism that controls a drive and steer transmission and that causes the transmission to execute turns in the direction a steering wheel is turned when operating in either the forward or reverse direction of travel. In response to operator engagement of a drive control, an actuation linkage shifts an elongate member within a slot formed in a cam member that pivots in response to turning of a steering wheel. Shifting of the rod member between two positions on either side of the cam member pivot axis causes the drive and steer transmission to steer the vehicle in the desired direction when the vehicle is traveling in both forward and reverse.
