ABSTRACT:
A dozer blade has (a) a face plate with an exterior surface, (b) an edge plate having a front surface, and (c) a replaceable cutting portion having a front surface and a thickness. The method includes the steps of forming the face plate to include a curved lower portion and attaching the edge plate to the lower portion. Attachment is at a position generally parallel to the projected exterior surface and spaced from the projected exterior surface by a dimension about equal to the thickness of the cutting portion. The method also includes the step of attaching the cutting portion to the edge plate so that the front surface of the cutting portion and the exterior surface of the face plate are generally coextensive. In that way, a "step" in the profile of the blade is avoided and material discharges more readily from the blade.
