摘要:
A crop feeding apparatus having a roller through which the fingers areextended and retracted, has fingers that are formed with tubular finger bodiesextending between an inner end configured to be mounted on a finger drivearrangement of the crop feeding apparatus and an outer end of the finger bodyconfigured to protrude from the outer peripheral wall of the roller. Abreakawayregion is formed in the finger body by diametrically opposed slots which arecircumferentially elongated to define a shear plane perpendicular to the longaxis ofthe finger body. A slot axis extending between opposing ends of each slot isparallelto the axis of the crop feeding apparatus. The finger body is also hardened byheattreating, and by applying a wear resistant coating over the heat treated body.
