ABSTRACT:
An agricultural harvesting assembly designed to remove vines and like undesirable growth from cultivated trees, plants and the like, comprising a frame movably and adjustably attachable to a tractor or like towing vehicle. A gripping head is movable and adjustably attached to the frame by an orienting means movably interconnected between the gripping head and the frame in such a manner as to absorb shock when the gripping head engages a tree from which vines are to be removed. Head disposition means and additional adjustment means are mounted on said frame and movably interconnected relative to the gripping head so as to position the gripping head between an operative and non-operative position and also in predetermined path of travel relative to a tree or obstacle intended to be encountered.
