Haymaking machine comprising an improved deflector

A haymaking machine comprising at least one plant pick-up and moving device, comprising a rotor able to be driven about a rotation axis which is substantially horizontal and substantially perpendicular to a direction of advance of the machine in a work position, teeth with teeth points describing a curve envelope when the rotor is driven about the rotation axis, and a conveyor which moves the plants transversely to the direction of advance, the machine also comprising at least one deflector which cooperates with the pick-up and moving device so as to receive, during work, a flow of plants moved by the conveyor so as to form a windrow, the deflector being connected to an arm which is itself connected, by means of a first articulation device, to the pick-up and moving device, by means of which first articulation device the arm can be pivoted, with respect to the pick-up and moving device, between a first position in which the deflector is arranged, in the work position of the machine, beside a lateral end of the pick-up and moving device and is remote from the lateral end, and a second position, wherein in the second position of the arm and considering the machine in the work position, the deflector and the arm extend substantially flat and at least partially above the pick-up and moving device.
