A mower-conditioner assembly of a self-propelled windrower includes a frame, a cutting mechanism coupled to the frame for cutting crop, a conditioner rotatably coupled to the frame at a location rearward of the cutting mechanism, and a fluffer assembly rotatably coupled to the frame at a location rearward of the conditioner. The fluffer assembly includes at least an elongated roll and a crop moving element. The conditioner crimps the crop after it is cut, and the fluffer assembly fluffs or moves the crop during operation.
