Abstract: A lock for a ground engaging tool may have a first diameter body portion, a neck portion extending from the body portion along a rotational axis of the lock and having a second diameter smaller than the first diameter, and a head portion extending from the neck portion along the rotational axis. The head portion may have first and second generally planar end surfaces extending from a bottom surface to a top surface, and first and second cam surfaces, which connect the end surfaces and each include a convex portion and a concave portion.

Abstract: A lock for a ground engaging tool may have a body portion having a first diameter. The lock may also have a neck portion, which may have a second diameter smaller than the first diameter. The neck portion may extend from the body portion along a rotational axis of the lock. The lock may also have a head portion, which may extend from the neck portion along the rotational axis. The head portion may have a surface facing the body portion, a top surface facing away from the body portion, first and second generally planar end surfaces extending from the bottom surface to the top surface, and first and second cam surfaces extending from the bottom surface to the top surface, and connecting the first and second end surfaces. A portion of the first cam surface adjacent the first generally planar end surface may have a first radius of curvature, and another portion of the first cam surface may have a second radius of curvature larger than the first radius of curvature.

Abstract: Disclosed are various exemplary embodiments of a ground engaging tool. The tool may have an engagement end. The tool may also have a mounting end opposite the engagement end along a longitudinal axis of the tool. The mounting end may have a first mounting leg. The mounting end may also have a second mounting leg, which may have a mounting surface facing the first mounting leg. The second mounting leg may define a cavity in the tool accessible only through an opening in the mounting surface.
