Abstract
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.
