  • Patent number: 11606894
    Abstract: An implement guidance module is provided for positioning a drawn implement as the implement is pulled by a vehicle traveling along a desired path of movement, the vehicle having a connection point for receiving a hitch. The module includes a module main frame having a first end configured for connection to the vehicle connection point, and a second end configured for connection to the implement, the main frame having a longitudinal axis, and having a pivot mount connected to the second end with an implement mounting plate pivoting relative to the module main frame about a pivot axis perpendicular to the longitudinal axis. A vehicle mounting plate defines the first end of the module main frame, and the implement mounting plate defines the second end of the module main frame.

  • Publication number: 20080060825
    Abstract: Embodiments of the present invention comprise a system for positioning a drawn implement having a transverse tool bar being pulled by a vehicle traveling generally along a desired path of movement, the vehicle having a mounting hitch on the rear end thereof where a system hitch is configured to adjust its angular orientation and that of the tool bar relative to the vehicle mounting hitch and a global positioning system having an antenna mounted on the system hitch operable to detect the position of the tool bar of the implement relative to the desired path as the vehicle moves generally along the desired path and generate a signal that is indicative of the lateral position of the implement relative to the desired path and means for controlling the hitch means to adjust the angular orientation of the hitch means and the tool bar so that the implement follows the desired path of movement in response to the global positioning system signals.

  • Patent number: 5421318
    Abstract: A portable pit cooking apparatus includes a heat distributing assembly which permits controlled burning of a solid fuel material and substantially uniform distribution of heat across the cooking region of the apparatus, a towing assembly which supports the heat distributing assembly above a support surface for rendering it mobile for transport over the support surface to a desired cooking site and for retaining a stationary once the desired site has been reached, a fire height adjusting assembly which permits tailoring of the position of the fire to the type of cooking to be carried out, a rotisserie assembly which provides for uniform and slow cooking of a large quantity of food and permits easy and quick removal and disassembly to clean the parts thereof and to convert to other cooking options, an adjustable hood assembly for covering the cooking chamber, and an ash collection and removal assembly which permits easy washout and cleanup of the apparatus.
