Abstract: A stack-fold implement having a central bulk fill hopper assembly is provided. The bulk fill hopper assembly is mounted to the center frame section of the stack-fold implement and does not affect the narrowness of the stack-fold implement when it's in a stacked, transport position. The hopper assembly includes a pair of bulk fill hoppers or tanks supported by cradle that is in turn supported by a pair of wheels. The cradle is removably coupled to the center frame section by a plurality of rigid frame members. A retractable ladder may be stowed beneath the hopper assembly.

Abstract: 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 reinforced 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.

Abstract: A rake comprising a frame provided with wheels, a subframe pivotally connected with said frame, two board supports pivotally connected with the subframe and a plurality of rake boards rotatably journalled at the board supports is improved with the object that it can be readily constructed in a simple manner, that it satisfactorily matches slopes and unevennesses of the ground and that it can be readily moved at will into the operative position or a transport position.For this purpose the subframe is formed mainly by relatively independently pivotable arms fastened to the frame.
