Abstract: A ground engaging tool assembly includes a ground engaging tip, an adapter, and a wear cap. The ground engaging tip has a ground engaging portion and a coupling portion including an interior surface defining a coupler pocket with an adapter opening and first and second lug openings. The adapter includes a mounting nose with first and second retention lugs extending from sides of the mounting nose along oblique taper angles. The mounting nose is disposed within the coupler pocket of the ground engaging tip with the first and second retention lugs extending into the first and second lug openings, respectively. The base includes a shoulder surface and a retention surface that define a mounting groove therebetween. The wear cap includes a mounting rail that is disposed within the mounting groove of the adapter to mount the wear cap thereto.

Abstract: A retention lobe for a ground engaging tip may include a lobe base having a base outline, wherein at least a portion of the base outline may lie in a base plane. The base outline may include a front base edge and a rear base edge opposite the front base edge. The retention lobe may also include a lobe outer surface spaced from the lobe base and extending from the front base edge to the rear base edge. The lobe outer surface may include a front lobe outer surface extending from the front base edge obliquely relative to the base plane and toward the rear base edge. The lobe outer surface may further include a rear lobe outer surface extending obliquely relative to the front lobe outer surface, such that the rear lobe outer surface tapers relative to the front lobe outer surface toward the base plane.
