A drafting structure for a multi-section implement having a plurality of interconnected implement sections arranged abreast to a line of draft includes a pair of spaced draft beams extended generally parallel to the line of draft and a pair of spaced spreader beams extended transversely thereto and forming a generally rectangular rigid frame. The frame is mounted over implement center sections and connected to wing sections thereof by hinges that enable folding of the implement for travel and, which when the implement is unfolded and in its working configuration, disperses and distributes the drafting forces and pressures that tend to cause arching of the center sections. Hitch arms are extended from the frame for connection to a prime mover.

Multi-section implement and drafting structure therefor

An implement frame construction includes rigid implement frame sections positioned in side-by-side relation and joined by a linkage system which permits the sections to universally flex within desired limits with respect to each other without substantial variation in lateral spacing therebetween. The linkage preferably includes forwardly and inwardly angled draw tongues vertically pivotally joined to the respective frames and flexibly connecting together in a tractor hitch, a front transverse spacer link extending between the tongues, a rear transverse stabilizing bar having opposite ends pivotally connected to the outer rear end portions of the respective frames, a vertical gag link positioned between the frames and centrally pivotally connected intermediate its ends to one of the frames, a first gag bar connected at its front end to the front inside corner portion of the other frame and at its rear end to one end of the gag link, and a second gag bar pivotally connected at its rear end to the rear inside corner portion of the other frame and at its front end to the other end of the gag link.
