Abstract: A ground engaging tip of a ground engaging tip assembly includes an adapter configured for attachment to the base edge of the implement and having a forwardly extending adapter nose. The ground engaging tip has a rear edge, a top outer surface, and a bottom outer surface. The top and bottom outer surfaces extend forward from the rear edge and converge at a front edge of the ground engaging tip. The tip has first and second side outer surfaces extending forward from the rear edge of the ground engaging tip to the front edge. The tip has a nose cavity for receiving the adapter nose therein. The tip has a support rib on at least one of the first or second side outer surfaces, the support rib being positioned at the rear edge and extending lengthwise from the bottom outer surface toward the top outer surface.

Abstract: In some implementations, a retainer sleeve may include a body including an at least partially annular configuration defining a retainer axis. The body may include an inner surface configured to rotatably receive an outer surface of a lock. The body may include a plurality of plates circumferentially joined together with respect to the retainer axis, where a first plate of the plurality of plates includes a first leg joined to the first plate extending away from the retainer axis and configured to contact a lock cavity of the lock. The body may include an anti-rotation feature, disposed on the first plate, extending inward from the inner surface toward the retainer axis, the anti-rotation feature including a locking surface configured to contact a lock skirt of the lock, the locking surface disposed at a first angle with respect to a bottom end of the first plate.

Abstract: A retainer sleeve for use with a lock in a ground engaging tool. The retainer sleeve may include an outer skirt extending around a retainer axis, where the outer skirt may include an outer surface formed to mate with a lock cavity of the ground engaging tool. The retainer sleeve can further include an inner sleeve flexibly connected to the outer skirt via a lower bend. The inner skirt may be formed to rotatably receive an outer surface of the lock. The retainer sleeve may also include a detent projection extending radially inward from the inner skirt with respect to the retainer axis and formed to engage a detent recess of the lock to releasably hold the lock.

Abstract: A ground engaging tip of a tip assembly for a base edge of a ground engaging implement has an adapter configured for attachment to the base edge of implement and having a forwardly extending adapter nose. The ground engaging tip has a rear edge, a top outer surface, and a bottom outer surface. The top outer surface and the bottom outer surface extend forward from the rear edge of the ground engaging tip and converge at a front edge of the ground engaging tip. The ground engaging tip also has a nose cavity, within the ground engaging tip and defined between the converging top and bottom outer surfaces of the ground engaging tip, for receiving the adapter nose therein. The nose cavity includes a wear indicator extending from an inner surface of the nose cavity, into the ground engaging tip, toward the bottom outer surface of the ground engaging tip.
