A hay harvesting machine including a frame with several windrowing rotors, the frame including a draft beam and a connecting beam which is articulated with respect to the draft beam, at least the rotor of the connecting beam located farthest back being equipped with a windrowing deflector. The machine includes a retractable stop for the movement of the connecting beam about its axis of articulation, and a device for shifting the deflector notably with respect to the corresponding rotor. A device controls the stop, which device is actuated by the shifting device. The stop prevents the connecting beam and the corresponding rotor from moving from a first work position into a second work position as long as the deflector can collide with the rotor which precedes it. When the deflector is shifted into a position where the risk of collision is eliminated, the stop is retracted and the change in position is possible.

Hay harvesting machine provided with at least a swathing rotor equipped with a deflector with adjustable position

Haymaking machine

A haymaking machine which includes a frame that has two windrowing rotors driven in rotation about substantially vertical axes, the frame having a linkage beam which connects the axle of the first rotor to that of the second rotor, the beam being articulated to the axle of the first rotor. The linkage beam includes at least one transverse joint shaft and the first rotor includes a toothed ring which meshes with a first gear wheel which is formed as one piece with a drive shaft and with a second gear wheel which is formed as one piece with a transmission shaft which extends to the second rotor and which includes a third gear wheel which meshes with a toothed ring of this rotor. The transmission shaft is housed in the linkage beam and is pivotable with the latter about the axle of the first rotor, the transmission shaft including at least one universal joint at the level of the joint shaft the linkage beam.
