Abstract: A crop feeding apparatus having a roller through which the fingers are extended and retracted, has fingers that are formed with tubular finger bodies extending between an inner end configured to be mounted on a finger drive arrangement of the crop feeding apparatus and an outer end of the finger body configured to protrude from the outer peripheral wall of the roller. A breakaway region is formed in the finger body by diametrically opposed slots which are circumferentially elongated to define a shear plane perpendicular to the long axis of the finger body. A slot axis extending between opposing ends of each slot is parallel to the axis of the crop feeding apparatus. The finger body is also hardened by heat treating, and by applying a wear resistant coating over the heat treated body.

Abstract: A hitching arm for a graff harvester comprising a rigid elongated element having two opposite ends for connection, respectively, to the graff harvester and to a propulsion device, wherein the arm has upwardly extending sections extending from each opposite end towards a centre of the hitching arm, and an elevated centre section. The shape of the arm allows the arm to pull a harvesting unit having a cutter head at the front extend over the cutter head.
