Abstract: An implement end cutting-bit with a body having front, rear, top, bottom, inner side and outer side portions. The body has a cutting edge along a bottom interface between the front and bottom portions. The body has a flat front surface on the front portion extending between a top edge along a top interface between the front and top portions, an outer side edge along an outer side interface between the front and outer side portions, a ridge on the front portion, and a spearhead edge along the bottom interface between the outer side portion and the cutting edge. The body has a contoured front surface on the front portion of the body adjacent the flat front surface. The contoured front surface can be defined between an inner side edge, which is along an inner side interface between the front and inner side portions, the cutting edge, and the ridge.

Abstract: A dozing blade assembly includes a dozing blade and a multi-piece cutter mounted to the dozing blade and including an elongate body having a first outer body piece and a second outer body piece that are mirror images of one another, and each including an inboard stem having a linear leading edge profile, and an integral outboard end bit having a curvilinear leading edge profile. The outer body pieces are structured for mounting to the dozing blade such that digging faces of the outer body pieces are oriented at a shallower angle than digging faces of the middle body piece, relative to a horizontal plane.

Abstract: A wear member including a body having front, rear, top, bottom, inner side and outer side portions. The wear member includes a front bottom edge, a front top edge parallel to the front bottom edge, a front inner side edge, and a front outer side edge. The wear member includes a front face defined on the front portion extending between the front inner side edge, the front outer side edge, the front top edge, and the front bottom edge. A lower wear indicator groove is formed in the front face parallel to the front bottom edge, and a lower wear face is defined between the front bottom edge and the lower wear indicator groove. The body mounts to the earth-working implement to dispose the lower wear face between a mounting edge and a work surface.
