Patent number: 11898320Abstract: A grading machine includes a machine body, a grading blade supported by a circle, a drawbar connecting the grading blade and the circle to the machine body, and a circle drive system. The circle drive system includes a circle drive motor with a motor shaft, a gear box, a gear coupling, and a braking mechanism. The gear box is configured to engage with and rotate the circle relative to the drawbar around a circle axis. The braking mechanism is positioned between the circle drive motor and the gear coupling and is configured to selectively engage the motor shaft.Type: GrantFiled: October 25, 2019Date of Patent: February 13, 2024Assignee: Caterpillar Inc.Inventor: Bruce R. Vahling

Patent number: 11505912Abstract: In accordance with one or more aspects, a circle drawbar for a motor grader has a drawbar frame having two elongated members, and a circle frame that has a surface defined by an inner and outer diameter. The circle frame has a circle gear located radially inward of the inner diameter, allowing the circle frame to be rotatable relative to the drawbar frame around an axis of the circle gear. A platform having a top, bottom, and an edge depends from the drawbar frame and covers the circle gear. A debris remover is connected to the platform and removes debris from the surface of the circle frame as the circle frame rotates.Type: GrantFiled: October 3, 2019Date of Patent: November 22, 2022Assignee: Caterpillar Inc.Inventors: Benjamin J. Kovalick, Lankesh Kumar Mathur Shanmukappa, Nathaniel K. Harshman, Bruce R. Vahling

Patent number: 8770612Abstract: A hitch system for automatically hitching a tractor to a trailing implement is provided. The hitch system may allow an operator that is in a cab of the tractor to remotely connect and electrical system and/or a hydraulic system of a tractor an implement to each other and to remotely secure a hitch pin that connects a tongue of the implement to a drawbar of the tractor. The hitch system may include implement and tractor connector bank assemblies that are respectively provided on the implement and tractor. The tractor connector bank assembly may be moveable in multiple directions for allowing the tractor connector bank assembly to be remotely controlled from the cab of the tractor to align and move into engagement with the implement connector bank assembly.Type: GrantFiled: April 19, 2012Date of Patent: July 8, 2014Assignee: CNH Industrial America LLCInventors: Keith W.
