Abstract: A haymaking machine, particularly a mower of plant matter with a grouping device allowing the plant matter cut in two passes to be grouped together into a double windrow or alternatively a single windrow to be formed. The grouping device is made of a first member for moving the plant matter toward the rear side of the machine and of a second member for moving the plant matter toward a side, the second moving member being mounted on a support in such a way that it can be moved closer to or away from the first moving member for forming a double windrow or a single windrow.

Abstract: A machine for harvesting forage including in particular a cutting mechanism and a device for treating the cut products. The treatment device includes at least two ribbed rollers which are driven in rotation by a transmission. The transmission includes at least one flexible element which collaborates with a driving member and driven members which are mounted on shafts which drive the rotation of the rollers. At least one of the driven members is mounted on its shaft by a freewheel configured to transmit rotational movement from the driven member to the shaft in just one direction.

Abstract: The mower of the present invention comprises a frame, a cutting mechanism supported by the frame, and a windrow grouping mechanism. In turn, the windrow grouping mechanism comprises a longitudinal conveying device and a transverse conveying device. The mower of the present invention is notable in that the longitudinal conveying device comprises at least one roller, the longitudinal axis of which is substantially perpendicular to a direction of forward travel of the mower. The roller is driven in rotation about the longitudinal axis so that its surface transports a product, cut by the cutting mechanism, toward the rear of the mower.
