ABSTRACT:
The disclosed flexible flail is molded from polyurethane. The flail has a relatively thin shank with a hub at one end so that the flail can be attached to the rotor of conventional defoliating apparatus and has a thicker portion at the end thereof opposite the hub. A plurality of metal studs have disk-like heads embedded in the thicker portion of the shank and the studs project from the side of the shank opposite the thicker portion in a direction so as to strike the leaves and remove same from sugar beets and the like while such beets are still in the ground.
