Abstract: A corner guard includes a rear attachment portion defining a first fastener receiving void, a rear edge that is disposed along the direction of material flow, and a forward ramp portion that extends forwardly from the rear attachment along the direction of material flow, and vertically downwardly forming a front wear edge. The corner guard also includes an outer lateral side, and an inner lateral side. The outer lateral side is flared laterally, defining an outer lateral side extremity that is disposed along the direction of material flow adjacent to the front wear edge, forming a flared portion.

Abstract: A work tool or a wear member includes a working portion or a wear portion, a hollow portion that further defines a lock receiving aperture defining an axis of rotation, a radial direction, and a circumferential direction. The axis of rotation is transverse to the direction of assembly of work tool or wear member as the member is slid over a nose portion of a tool adaptor or the like. The axis of rotation is spaced away from the direction the pin receiving thru-hole extends a predetermined distance measured along the direction of assembly.

Abstract: A cutter bit for a work tool on a machine includes a leading end, conical-shaped tip portion, a rearward, frustoconical-shaped tip portion extending axially rearwardly from the leading end, conical-shaped tip portion, an annular ledge extending radially outwardly from a trailing edge of the rearward, frustoconical-shaped tip portion, a frustoconical-shaped body portion extending axially rearwardly from an outer circumferential edge of the annular ledge, a cylindrical collar portion extending axially rearwardly from a trailing edge of the frustoconical-shaped body portion, and a trailing end, cylindrical-shaped shank portion extending axially rearwardly from the cylindrical collar portion. The cutter bit may also include a plurality of circumferentially-spaced ribs projecting radially outwardly from an outer peripheral surface of at least one of the leading end, conical-shaped tip portion, the rearward, frustoconical-shaped tip portion, or the frustoconical-shaped body portion.
