  • Patent number: 11028557
    Abstract: A work vehicle comprising a work vehicle control comprising a standard configuration and an updated configuration. A controller is configured to receive a geospatial positioning signal, a boom position signal, an attachment position signal, and an operator input. The controller is configured to reference a memory device and change the work vehicle control between the standard configuration and the updated configuration. The controller is configured to control an elevation of the attachment according to a grade command.

  • Publication number: 20200181869
    Abstract: A work vehicle comprises a frame. At least one ground engaging device is coupled to the frame and configured to support the frame above a surface. A boom assembly is coupled to the frame and configured to move from a lowered position to a raised position. An attachment coupler is coupled to a distal portion of the boom assembly. At least one tilt cylinder coupled to the boom assembly and the attachment coupler. A boom lock is coupled to at least one of the frame and the boom assembly. The boom lock is configured to move from an unlocked position where the boom assembly is movable to a locked position where the boom assembly is locked to the frame in the lowered position.
