ABSTRACT:
One or two conventional picking units are mounted on a two-wheel, high clearance running gear or frame. A two-point hitch is coupled to the draft links of a tractor or an equal-angle hitch is coupled to the tractor drawbar. Hitch and tongue interface on the harvester facilitates sharp turn angles between the implement and the tractor through use of a pivoting member containing the driveline powering the units from the tractor. A center pivot tongue allows offset for appropriate row alignment and provides improved maneuverability and implement steering on headlands and turn rows. A hydraulic cylinder connected to the tongue or a crossed four-bar linkage structure controls tongue angle. A basket is supported at the rear of the frame and the row units are located forwardly of the frame to provide counterbalancing forces about the wheel axis.
