ABSTRACT:
A steering mechanism for an excavator or similar vehicle having a pair of steerable wheels and a pair of fixed wheels wherein the steerable wheels are carried by a movable steering fork which is mounted on a circular-shaped rail such that movement of the steering fork around the rail causes steering of the steerable wheels. The axes of rotation of the steerable and fixed wheels remain substantially equidistant from the center of the circle defined by the rail in all positions of the steering fork on the rail. Fluid motors carried by the excavator are operatively connected to the steering fork for moving same around the rail.
