Abstract: An edge protector for mounting to a lip of a ground engaging tool and shielding an edge of the lip is disclosed. The edge protector may include a tip configured to extend forward from the edge of the lip of the ground engaging tool. The edge protector may also include a first mounting leg extending rearward from the tip. Additionally, the edge protector may include a second mounting leg extending rearward from the tip and spaced from the first mounting leg by a recess configured to receive the lip of the ground engaging tool between the first mounting leg and the second mounting leg. The first mounting leg may include a lock cavity configured to house a lock in such a manner that the lock is sandwiched between the first mounting leg and the lip of the ground engaging tool.

Abstract: Disclosed are various exemplary embodiments of a retainer bushing for use with a lock in a ground engaging tool. The retainer bushing may include a skirt extending around a retainer axis, where the skirt may include an outer surface configured to mate with a lock cavity of the ground engaging tool and an inner surface configured to rotatably receive an outer surface of the lock. The retainer bushing may also include a detent projection extending radially inward from the inner surface with respect to the retainer axis and configured to engage a detent recess of the lock to releasably hold the lock. The detent projection may include a convex surface with a substantially constant radius, and a center of the radius of the convex surface may be positioned at a first distance from the retainer axis that is greater than a second distance between the retainer axis and the outer surface of the skirt.
