Abstract
A mower includes a linking structure designed to link the mower to a motor vehicle; a cutting mechanism with driven cutting elements that include cutting tools; and a windrowing device designed to move laterally, toward a median plane of the cutting mechanism, the product that has been cut by the cutting elements before it is dropped to the ground. The windrowing device has at least one guiding element for the cut product, located in the vicinity of one of the lateral ends of the cutting mechanism, and considering the direction of work, behind the front of the cut of the cutting mechanism. The guiding element has at least two rotors arranged crosswise to the direction of work and to the rotation axis directed upward during work. The rotors are hung to a carrying structure linked to the cutting mechanism and/or to the linking structure, and the rotors are driven in rotation by way of a driving mechanism. The rotors are windrowing rotors that are arranged in the immediate vicinity of one another and are hung to the carrying structure from their top, and the lower end of a windrowing rotor extends at least to the cutting plane defined by the cutting tools of the corresponding cutting …
