Abstract
This invention relates to a haymaking machine which includes a frame having a central section and three lateral sections which are connected to one another and which carry rotors rotatably driven during working operation. The lateral sections can be folded for transport by hydraulic cylinders. On each side of central section there are located the three lateral sections, each of which includes a pipe and a housing equipped with a rotor. A hydraulic cylinder extends directly from the central section to each third lateral section and in the transporting position, the first and second lateral sections are directed upward and the third lateral sections are directed downward.

A haymaking machine for being coupled to a tractor and which comprises a frame carrying a plurality of rotors driven in rotation during working operation by transmission elements which are housed in the frame
- said frame including:
- a central section
- a first, second and third lateral section placed on each side of said central section, said central and said lateral sections being connected to one another by pins oriented so as to extend in the direction of movement of the machine
- wherein each of said lateral section comprises a pipe and a housing equipped with a rotor
- and wherein a hydraulic cylinder extends directly from said central section to each third lateral section for transporting said lateral sections into a working position in which said lateral sections are approximately aligned and a transporting position in which said lateral sections are folded about said pins, so that said first and second lateral sections being directed upward and the third lateral section being directed downward starting from their respective pins.
