FLEXIBILITY FOR WIDE SWATH AGRICULTURAL IMPLEMENTS

摘要

FLEXIBILITY FOR WIDE SWATH AGRICULTURAL IMPLEMENTS Improvements in flexibility for wide swath agricultural implements having hinged wing frame sections to enable the implement to be folded compactly for transport and also to better follow ground contours are provided by dividing at least one of the sections into side-by-side subsections which are pivotally interconnected for relative movement about a transverse axis. Thus, relative flexing between adjacent frame portions can take place about hinge axes parallel to travel direction while relative flexing between adjacent wing sections of the frame can take place about transverse axes. Preferably the pivotal interconnections are located to divide the frame into portions of equal width and the pivotal interconnections are reenforced by link means which connect the adjacent portions to resist bending movements about a vertical axis at the interconnection while still permitting the hinged sections to be folded.
