Abstract
Abstract A crop harvesting apparatus particularly suited for harvesting of tree-borne crops. Each of a plurality of crop-severing rods has its first end rotatably connected to a support plate so that the rods extend substantially perpendicular to the plate. Each crop-severing rod includes a shaft member and a cover member. Each cover member has a substantially circular cross-section of undulant diameter. Preferably, the maximum undulant diameter of each rod is adjacent the minimum undulant diameter of adjacent rods. The rods are thrust among crop-bearing foliage and rotated to remove the crops from the foliage. In one embodiment a crop catcher is provided, including a flexible body member, capable of assuming a rolled position, adjacent the apparatus, and an extended position overlying an area of ground to catch crops severed from crop-bearing foliage by the crop-severing rods.
