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.

A rear or duplex swather can be attached to the front swather by a duplex hitch which provides steering movements of the rear swather in a direction opposite to the steering movements of the front swather so that the former properly tracks the latter in echelon relationship.

Abstract: An agricultural implement of the type capable of folding from a wide operating mode to a narrow transport mode. The folding involves forward folding of the right and left wing sections alongside the central, fore-and-aft hitch. Featured are support wheels respectively for the wing sections which are selectively movable from the extended, forward positions in the operating mode to retracted or rearward positions in the transport mode to enable the wing sections to be more closely folded relative to the hitch and thus to achieve a narrower transport width. The closely spaced end-to-end relationship of the wing sections in operating mode provide for relatively narrow row spacing because only the hitch intervenes between the proximate ends of the sections.
