摘要： A foldable root crop defoliator wherein the implement has a central frame with lateral wings pivotally attached to the central frame. The front end of the central frame is adjustably attached to a hitch for towing the defoliator. Plant top cutting and shredding devices are mounted to the wing frames and are driven by a power train connected to the power-take-off (PTO) of the towing vehicle. In a use orientation, the two lateral wings are independently adjustable relative to the ground. Also, they have a range of free motion, and are able to "float" independently over the ground that they are immediately above. For a travel or storage orientation, each lateral wing is rotated upward to a vertical position by actuating a lifting device mounted on the central frame. The lifting device includes, for example, a piston and cylinder, and toggle linkage assembly. By being foldable, the defoliator may be reduced to a much smaller width, making it safer to transport and easier to store.
