  • Publication number: 20240341222
    Abstract: A header for an agricultural vehicle includes: a header frame; a flexible cutter supported by the header frame and including a plurality of cutting edges; a support arm coupled to the flexible cutter and pivotable with respect to the header frame; and a sensor assembly including a pivot sensor directly coupled to the support arm and a linkage including a linkage arm coupled to the pivot sensor and the support arm such that pivoting of the support arm also causes pivoting of the linkage arm, the pivot sensor being configured to output a total pivot angle signal corresponding to a pivot angle of the support arm plus an additional pivot angle of the linkage arm when the support arm and the linkage arm pivot.

  • Publication number: 20230165193
    Abstract: A crop divider includes a housing including an interior cavity and an adjustment assembly disposed within the interior cavity of the housing. In an embodiment, the adjustment assembly is configured to adjust a height of the housing relative to ground. In an embodiment, the adjustment assembly includes an adjustment handle disposed within the interior cavity and a pivot disposed vertically above the adjustment handle within the interior cavity of the housing. In an embodiment, the housing is configured to rotate about an axis through the pivot in response to rotation of the adjustment handle.

  • Patent number: 11234371
    Abstract: A divider of a header for an agricultural vehicle including a divider body, a receiving member configured for being connected to the frame of the header, and an adjustable connector positionable in between an unfolded work position and a folded transport position. The adjustable connector includes a first member, a second member, and an articulating joint for pivotally connecting the first and second members. The first member mounts the divider body, the second member is slidably connected to and received within the receiving member, and the articulating joint is at least partially received within the receiving member in the unfolded work position such that the first and second members are substantially immobilized and the articulating joint is positioned outside of the receiving member in the folded transport position such that the first and second members are movable relative to one another.

  • Patent number: 11083124
    Abstract: A scraper blade for a row unit of a planter. The scraper blade has a connecting portion that connects to the pivot hub of a depth-gauge assembly. The connecting portion connects to a blade portion. The blade portion is positioned in a gap formed between the pivot hub and the contact surface of the depth-gauge wheel. The scraper blade is connected to the depth-gauge assembly in a static and stationary position at a pivot point. As a pivot arm and the depth-gauge wheel move about in relation to the pivot point, the scraper blade maintains a fixed position at close tolerances with the depth-gauge wheel to remove soil and debris from the depth-gauge wheel.

  • Patent number: 7950212
    Abstract: A system for supporting a cutterbar of a crop harvesting header includes a first arm pivotably secured to the header. The first arm includes a first portion configured to support the cutterbar. The first arm includes a second portion including a torsion device having a mass of elastic material connected to an adjustment assembly. The second portion is configured to be pivotably rotatable about an axis by the adjustment assembly to selectably increase or decrease a force appliable to the first portion in order to raise or lower the first portion with respect to the header.
