Embodiment Construction

[0020] Such as figure 1 As shown, the machine according to the invention is a crop windrower placed on the ground. It comprises a support structure 1 comprising a central beam 2 with connecting means 3 at its front end for hooking the central beam to a tractor (not shown) so that the machine can be moved in an advancing direction A. In the remainder of the description, the term "front" is defined in terms of the direction of travel A.

[0021] The rear end of the central beam 2 has a crossbar 4 provided with wheels 5, 6 rolling on the ground. Each side of the central beam 2 is articulated via substantially horizontal shafts 7, 8 with arms 9, 10 carrying rotors 11, 12 having work implements 13 intended to heap crops such as grass Or cut straw lying on the ground. In the example shown, the arms 9 , 10 and the corresponding rotors 11 , 12 are biased in the advancing direction A. As shown in FIG. The crops piled by the frontmost rotor 11 can be processed again by the rearmost ...
