摘要： 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.

摘要： 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 that faces at least partially in the circumferential direction and along a direction that is parallel to the axis of rotation, forming an oblique angle with the direction that is parallel to the axis of rotation.

摘要： 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.

摘要： A spring loaded retainer includes a lug receiving portion defining a first maximum outside dimension, the lug receiving portion also 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. A drive portion defines a second maximum outside dimension, and a first flat is disposed on the outside of the lug receiving portion proximate to the first sidewall or the second sidewall.

摘要： 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.
