Abstract: Rotor strippers are sized and shaped to securely fit between adjacent rotor fingers on a rotor shaft of a rotor for stripping crop material and for conveying the crop material to a bale chamber for forming a bale. Each rotor stripper is formed of a segment comprised of two opposing side walls with an interior section extending between the two opposing side walls. A first end portion has a curved hook section shaped to securely fit around a majority portion of the rotary shaft for secure engagement therewith; a second end portion is secured to a backbone portion of the rotor allowing the segment to remain fixed with respect to rotation of the rotary shaft; and a middle portion extends between the first and second end portions in a curved manner.
