  • Implement ground engaging tip assembly having tip with tapered retention channel
    Patent number: 11788260
    Abstract: A ground engaging tip of a ground engaging tip assembly includes an adapter that attaches to the base edge and having a forwardly extending adapter nose, and a ground engaging tip. The tip has a rear edge and a top and bottom outer surfaces. The top and bottom outer surfaces extend forward from the rear edge of the ground engaging tip and converge at a front edge of the tip. The tip includes first and second side outer surfaces extending forward from the rear edge to the front edge. Tip includes a nose cavity for receiving the adapter nose therein. The nose cavity has first and second side inner surfaces opposite the first and second side outer surfaces, respectively. The nose cavity has an aperture and a retention channel on at least one of the first and second side inner surfaces. The retention channel extends from the rear edge to the aperture and guides a lug of the adapter into the aperture during installation of the ground engaging tip on the adapter.

  • Implement tip assembly having tip with wear indicator
    Patent number: 11613874
    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.
