ABSTRACT:
A dozing machine comprises a tractor having a transverse dozing blade mounted at the forward end thereof. Steering changes can made by shifting the lateral centerline of the blade laterally relative to the longitudinal centerline of the tractor. To this end, a linear actuator is connected between the blade or a blade push arm and the tractor. The actuator is extended or retracted to shift the centerline of the blade. The centerline may also be shifted by extending the length of the blade to one side of the tractor centerline. Automated methods and apparatus are disclosed which utilize blade centerline shifting to maintain a desired direction of travel or to automatically achieve any desired path. Also, sideshifting of the blade may be useful for purposes other than steering the tractor.
