A power angling bulldozer comprises a blade operatively connected to the forward end of a C-frame by spaced links arranged to diverge toward each other forwardly of the frame. A pair of double-acting hydraulic cylinders are pivotally connected between the frame and blade to selectively impart angling movements to the blade for earth-moving purposes. The links are constructed and arranged so that the blade will completely cover and protect the frame during all such movements. A third double-acting hydraulic cylinder may be operatively associated with the blade to selectively impart tilting movements thereto.
