  • Patent number: 12774581
    Abstract: A work machine configured to operate on a ground surface. The work machine comprises a frame, a cab supported by the frame and configured to house an operator of the work machine, and at least one loader arm supported on the frame and shiftable relative to the frame between a raised position and a lowered position. The frame includes (i) a forward portion and a rearward portion, and (ii) a first side and a second side. The first side and the second side are laterally separated from each other. At least the first side of the frame comprises an inner panel and a cover panel at the rearward portion of the frame. The cover panel is spaced outwardly from the inner panel. At least a portion of a top edge of the cover panel is positioned vertically lower than a top edge of the inner panel.

  • Publication number: 20260286644
    Abstract: A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve f(x)=4.641e0.34x. The value “x” represents a horizontal direction and the function f(x) represents a vertical direction.
