ABSTRACT OF THE DISCLOSURE CROP HARVESTING APPARATUS AND METHODS Apparatus for harvesting crop comprises a rotor 11 mounted on a mobile frame 12 and carries a succession of transverse combs 14 each formed of an array of outwardly projecting teeth 15 transverse to the direction of movement of the apparatus through the crop. Each tooth 15 is pointed with side edges diverging away from the distal tip of the tooth. The rotor rotates in the overshot mode and the combs intrude into the crop and gather crop stems between adjacent pairs of teeth and detach grain and grain heads, or other required crop parts, by rubbing or breaking the parts free from the stems. The junction of adjacent teeth 15 preferably has an enlarged aperture 21 to assist stripping and to allow withdrawal of stripped stems. In other arrangements the teeth may be replaced by a brush-like structure or by rods or other crop engaging elements, backed by plain transverse ribs for collecting and conveying detached crop parts.
