Publication number: 20240101201Abstract: A track assembly for assisting in moving a farm implement along a ground surface in a line of travel is provided. The track assembly includes a tilt arm comprising front and rear ends. The track assembly includes a camber arm coupled to the tilt arm such that the camber arm permits the tilt arm to pivot about a first axis perpendicular to the line of travel and a second axis parallel to the line of travel. The camber arm is located between the front and rear ends of the tilt arm.Type: ApplicationFiled: September 12, 2023Publication date: March 28, 2024Applicant: Unverferth Manufacturing Company, Inc.Inventors: Michael D. VAN MILL, Christopher M. SELF, John WALVATNE

Patent number: 11910754Abstract: A grain cart and foldable auger assembly having an upper auger assembly portion with a discharge portion, a lower auger assembly portion with an intake portion, and a compound angle joint that allows the upper auger assembly portion to be moved between operating and transport positions. When in an operating position, the upper auger portion and the lower auger portion are offset from each other by an operating offset angle. When in a transport position, the upper auger assembly portion is offset from the lower auger assembly portion by a transport offset angle such that the upper auger assembly portions folded across the front of the grain cart in a non-obstructive and non-protruding manner.Type: GrantFiled: April 20, 2021Date of Patent: February 27, 2024Assignee: UNVERFERTH MANUFACTURING COMPANY, INC.Inventors: Michael D. Van Mill, Ronald J. Schlimgen, John Walvatne, Christopher M. Self
