Abstract
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.
