Abstract
A master slave steering system is provided for earth construction machinery having front and rear steerable wheels or tracks. A front steering sensor is connected to control the front wheel or track, and the rear wheel or track is controlled either from a rear steering sensor in an automatic mode or in response to the steering of the front wheel or track in a slave mode to insure that, in the automatic mode, the front and rear wheels or tracks are rotated independently as dictated by their respective sensors and, in the slave mode, the front and rear wheels or tracks are rotated in an opposite direction with respect to one another.
