Patent number: 9216681Abstract: 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: May 22, 2015Date of Patent: December 22, 2015Assignee: Unverferth Manufacturing Company, Inc.Inventors: Michael D. Van Mill, Ronald J. Schlimgen, John Walvatne, Christopher M. Self

Patent number: 9205715Abstract: A towable farm implement includes a plurality of wheel assemblies coupled to a frame by a plurality of suspension systems. Each suspension system includes an upper support structure and a lower support structure. Each of the upper and lower support structures have a first end configured to be pivotably coupled to the frame about a first pivot axis parallel to a longitudinal axis of the frame, and a second end pivotably coupled to a portion of the wheel assembly about a second pivot axis parallel to the first pivot axis. Each suspension system further includes a damping device having a first end configured to be pivotably coupled to the frame, and a second end pivotably coupled to the wheel assembly. The damping device is configured to move the wheel assembly generally vertically while maintaining the longitudinal position and, optionally, a steering angle of the wheel.Type: GrantFiled: January 13, 2012Date of Patent: December 8, 2015Assignee: Unverferth Manufacturing Company, Inc.Inventors: Michael D.

Patent number: 8967727Abstract: A gravity wagon includes a container for storing grain or other material and a discharge for allowing material to exit the hopper via gravity. A discharge chute and kickback are used to direct the material from the discharge and are coupled via a linkage such that they can be positioned to direct the material exiting the hopper to an area generally to the side of the hopper in a first position or an area generally towards the center of the hopper in a second position. The movement of the discharge chute and the kickback between the first and second positions is facilitated by a pusher or pushing member coupled to the kickback.Type: GrantFiled: July 2, 2012Date of Patent: March 3, 2015Assignee: Unverferth Manufacturing Company, Inc.Inventors: Michael Van Mill, John Walvatne, Daryl Rubner

Patent number: 7810823Abstract: An oscillating in-line steering system for a pulled agricultural implement includes first and second in-line axles pivotably coupled with a frame. The system also includes at least first and second in-line wheel arrangements pivotably coupled with the first and second axles respectively. Each wheel arrangement has a plurality of pivotable wheel assemblies arranged in-line and wheel linkages coupling the in-line wheel assemblies such that in-line wheel assemblies oscillate together. A right-to-left linkage couples the wheel linkage of the first in-line wheel arrangement to the wheel linkage of the second in-line wheel arrangement so that the first in-line wheel arrangement oscillates at a steering angle proportional to that of the second in-line wheel arrangement.Type: GrantFiled: August 21, 2007Date of Patent: October 12, 2010Assignee: Unverferth Manufacturing Co., Inc.Inventors: Michael D.
