Abstract: A base includes a male portion including a first projection, and a second projection facing in a diametrically opposed manner to the first projection. A stepped bore extends from the first projection to the second projection that has a large diameter portion that is at least partially formed by the first projection.

Abstract: A wear member includes a body defining an exterior with an outside perimeter, an interior aperture with an at least partially interior polygonal perimeter, and at least one fastener receiving hole extending from the exterior to the interior aperture. The exterior lacks any large openings to limit the risk of material packing.

Abstract: A cutting edge tip includes an attachment portion defining an adapter receiving void. A working portion extends forwardly from the attachment portion. A first lateral end portion is disposed along the lateral direction, the first lateral end portion defining a first lateral end surface that jogs laterally. Also, a second lateral end portion is disposed along the lateral direction opposite of the first lateral end portion. The second lateral end portion also defines a second lateral end surface that jogs laterally.

Abstract: The top cover defines a first fastener receiving void that is disposed along the direction of material flow between the forward ramp portion and the rear edge. The top male angled surface of the top cover defines a first material flow groove that extends along the direction of material flow, and includes a first flow ramp. The first material flow groove is disposed adjacent along the lateral direction and the direction of material flow to the first fastener receiving void.

Abstract: A load sharing block includes a body including a flat outer surface defining a first end and a second end, a first arcuate outer portion extending from the first end of the flat outer surface, and a second arcuate outer portion extending from the second end of the flat outer surface. The first arcuate outer portion terminates at a first free end and includes a first elliptical outer surface extending from the first free end.

Abstract: A retainer sleeve includes an at least partially annular body defining an axis of rotation, a radial direction, and a circumferential direction. The body may also have a radially inner annular surface defining a radially inner aperture, and a first anti-rotation feature extending radially inwardly from the radially inner annular surface including a sloping ledge having a locking surface, and an outer peripheral surface defining a notch that is at least partially aligned with the first anti-rotation feature or an array of a plurality of external ribs extending outwardly radially from the outer peripheral surface.

Abstract: A retainer includes a drive portion defining a drive portion outer diameter, and a lug receiving portion with a skirt defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. The skirt also defines a skirt outer diameter that is greater than the drive portion outer diameter. Also, the drive portion has a hook tab that extends from the drive portion and that is spaced away from the skirt a minimum distance.

Abstract: Each of the plurality of center notches and the first and the second end notches of a base edge includes a different configuration including a different end notch depth along the direction of assembly that is greater than a center notch depth along the direction of assembly.

Abstract: An adapter cover includes a front face portion that defines a thru-hole configured to allow a nose portion of an adapter to pass horizontally through the thru-hole past the interior surface and then past the exterior surface, and a top single leg extends horizontally from the front face portion. The thru-hole defines a perimeter with a right side edge, a left side edge, a top edge, an upper right corner and an upper left corner, and further defines a bottom open end.

Abstract: An adapter includes a first leg, a second leg, and a throat portion at least partially define a slot that defines a projection at the closed end of the slot that includes a flat middle portion straddled laterally by a first arcuate portion and a second arcuate portion, defining a lateral middle portion width. A projection protruding distance is measured along the direction of assembly from the closed end of the slot to the flat middle portion. The projection protruding distance ranges from 0.8 to 1.2 multiplied by the lateral middle portion width.

Abstract: An adaptor includes a body defining a longitudinal axis, and a transverse axis that is normal to the longitudinal axis. The body also has a leading portion defining a lock receiving recess extending transversely at least partially through the leading portion, and a wire receiving conduit that is in communication with the lock receiving recess.
