ABSTRACT:
A crop harvesting apparatus having a plurality of rotatable crop-severing rods of generally circular cross section extending from a support for insertion into crop-bearing foliage with the crop-severing rod longitudinal axes substantially parallel to the direction of thrust. In one embodiment of the present invention, the rods are formed of a rigid, flexible material and are rotated at speeds sufficient to cause the rods to flex to rotate orbitally about the stationary positions of their longitudinal axes. In a second embodiment, the crop-severing rods have frictional surfaces on at least the longitudinally outer portions thereof. These crop-severing portions of the rods have no significant abrupt enlargement of diameter, and so no bulges exist which might contact and sever immature fruit or foliage from a crop-bearing plant. The rods are rotated and are thrust into a crop-bearing plant, and the frictional surfaces contact the crops to remove the mature crops from the plant.
