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: A wear member includes a forward working portion that is disposed along its longitudinal axis including a closed end, and a rear attachment portion that is disposed along the longitudinal axis including an open end with an exterior surface, and an interior surface. The interior surface defines an interior counterbore with a major diameter, and a minor diameter. A ratio of the major diameter to the minor diameter ranges from 1.8 to 2.2.

Abstract: 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.

Abstract: A lock assembly for attaching a wear member to a base includes a threaded retaining block with a C-spring attached to the retaining block that fits into an aperture of the base. A threaded lock pin fits into the aperture of the wear member, and the threaded aperture of the retaining block, retaining the wear member onto the base. The threaded lock pin engages the C-spring that prevents unintentional rotation of the threaded lock pin so that the threaded lock pin is trapped in the aperture of the wear member, preventing its unintentional removal.

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 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.
