ABSTRACT:
A fore-and-aft extending transport hitch frame carried on a pair of ground wheels supports the innermost ends of a pair of end wheel wing drills and tows a trailing end wheel drill between the wing drills. The wing drills are connected to rearwardly angled upright pivot structures on the hitch frame by hinged bracket structure which causes the innermost ends of the wing drills to lift as the drills are pivoted forwardly toward a transport position. The forward end of the hitch frame is lifted to raise the outboard ends of the wing drills for transport. During planting operations the ground wheels effectively act as the inboard end wheels for the wing drills. The wing drills can rock vertically about the bracket structure hinge for good flexibility in the field-working position.
