ABSTRACT:
An earth working dozer or tractor having a transverse blade and an adjustable spiral auger supported forward of the blade which further crushes material lifted by the blade and moves the material transverse of the blade. The blade includes opposed support-drive links which are pivotally supported at one end on top of the blade and which extend forwardly to receive the auger. The links are connected by a bar, spaced from the pivotal support, which is connected to the dozer frame by one or more hydraulic piston-cylinders. The position of the auger relative to the blade may thus be adjusted in parallel relation by extending or retracting the piston-cylinders, swinging the spiral auger about the pivot axes of the support links.
