Abstract:

An implement for general purpose broadcast or precision row crop cultivation comprising a central frame and two hingedly connected wings, or outer frames, all adapted for attachment of plow shanks at essentially any lateral position. The center frame includes cantilevered gauge wheel mounts extending beyond the hinge region so that gauge wheels for the center section are positioned in front of the side sections. Additional gauge wheels are carried by the wing sections at their ends opposite the center section. Hydraulic cylinders are provided for lifting the wing sections to an upright transporting position and latches are provided on the center section for holding the wing sections upright when the hydraulic cylinders are deactivated. Three point hitch members are provided on the front edge of the center section adapted for connection to standard tractor three point hitches with the cultivator spaced very closely to the rear of the tractor. Braces, hitches and gauge wheel connections are made by bolting to the frame cross members so that each part may be adjusted as necessary to accommodate essentially any plow shank pattern.
