  • Patent number: 11910754
    Abstract: 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.

  • Publication number: 20230227115
    Abstract: A track assembly for a farm implement includes a camber arm mounted in a camber arm housing, a first mounting bracket coupled to the upper connection point on the front end and pivotably coupled to the lower pivot point on the front end, and a second mounting bracket coupled to the upper connection point on the back end and pivotably coupled to the lower pivot point on the back end. The track assembly further includes first and second set arms having idler wheel sets mounted on one end and bogie wheel sets mounted on another end. The first set arm is pivotably coupled to the first mounting bracket, and the second set arm is pivotably coupled to the second mounting bracket, such that the idler wheel sets and bogie wheel sets are movable in opposing vertical directions.

  • Publication number: 20230070248
    Abstract: A farm implement is provided having a frame and first and second track assemblies for assisting in moving the farm implement along a ground surface in a line of travel. The first track assembly and the second track assembly are positioned on opposite lateral sides of the frame. The first track assembly has a first track frame, a first idler wheel, and a first brake assembly. The first idler wheel has an inboard side facing toward a center of the first track frame and an outboard side facing away from the center the first track frame. The first brake assembly has a first disc coupled to the first idler wheel on the outboard side of the first idler wheel, a first caliper couplable to first and second sides of the first disc, and a first torque arm coupled to the first track frame and a spindle of the first idler wheel.
