  • Patent number: 11993319
    Abstract: An operator station for a cab of a work vehicle is provided. The operator station includes a base frame configured to be fixedly secured to a floor of the cab; an operator chair including a chair frame rotatably coupled to the base frame to rotate about an upright swivel axis; and a first chair arm positioned on a lateral side of the operator chair. The first chair arm includes a first chair arm body; and a first chair arm adjustment mechanism coupled to the base frame and the first chair arm body and configured to pivot the first chair arm body about a lateral axis substantially perpendicular to the swivel axis as the chair frame rotates about the swivel axis with respect to the base frame.
    Type: Grant

  • Patent number: 11975768
    Abstract: An operator station includes a base frame; a chair is configured to swivel in first and second clock directions; and first and second chair arms. The first chair arm includes a first chair arm body disposed proximate and repositionable with respect to a first lateral side of the chair; and a first chair arm adjustment mechanism coupled to the base frame and the first chair arm body and configured to permit the first chair arm to rotate in a first lateral plane relative to the chair in the first clock direction when the chair rotates in the second clock direction relative to the base frame and to rotate in the first lateral plane relative to the chair frame in the second clock direction when the chair rotates in the first clock direction relative to the base frame.

  • Patent number: 7690973
    Abstract: A harvesting machine including a frame, a plurality of ground engaging wheels, at least one grain separating section, a plurality of cross augers and a grain moving device. The plurality of ground engaging wheels support the frame. The at least one grain separating section is supported by the frame. The plurality of cross augers are positioned to receive grain from the at least one grain separating section. The plurality of cross augers each have an end. The grain moving device is associated with each of the plurality of cross augers proximate to the end of the plurality of cross augers.

  • Patent number: 6691861
    Abstract: A discharge chute for the unloading auger of a combine is provided with a discharge opening which provides maximum discharge flow rate and maximum clearance for moving and positioning of the auger. The discharge chute has an upper surface extending downwardly at a first angle relative to a horizontal plane, and a lower surface extending downwardly in a second angle relative to a horizontal plane. The first angle of the upper surface is greater than the second angle of the lower surface. The discharge chute also includes an internally mounted dribble door pivotal between raised and lowered positions. The door prevents grain dribble when in the upper position, and allows unobstructed grain discharge when in the lowered position.
