  • SECURING ATTACHMENTS TO WORK VEHICLES WITH SUSPENSION CONTROL
    Publication number: 20180009285
    Abstract: A system and a method for securing an attachment to a work vehicle with a chassis and a suspension are described. A mounting frame with a frame attachment point disposed on a support can be attached to a work vehicle. The suspension can be caused to lower the mounting frame relative to ground by lowering the chassis of the work vehicle. The work vehicle can be maneuvered to align the frame attachment point with a corresponding attachment point on the attachment. The suspension can then be caused to raise the mounting frame relative to ground by raising the chassis of the work vehicle. The frame attachment point can thereby engage the corresponding attachment point on the attachment, as the mounting frame is raised, in order to lift the attachment, with the attachment being thereby supported by the work vehicle solely via the mounting frame.
