ABSTRACT:
A plant trimming apparatus comprises a cutting device operated in conjunction with a support apparatus. The cutting device includes an elongated handle member attached to a cutter, the cutter being preferably an electrical chain saw or tree trimmer. A power cord for the electric cutter is carried through a hollow portion of the handle to an electrical outlet or generator which provides power. The handle is preferably a hollow PVC tube. The handle is supported by a fulcrum apparatus which provides leverage for manipulating the cutter. The fulcrum apparatus comprises a pair of hollow tubes hingedly connected together to provide a V-shaped fulcrum point in which the handle rests. A third leg of pipe is hingedly connected to one of the legs, further down from the fulcrum point, to act as a third leg of a tripod. The third leg can be raised and held in the operator's hand for moving the fulcrum point fore and aft during the cutting operation. The blade of the cutter is mounted so that it forms an angle with the longitudinal axis of the handle, to allow different angles to be obtained in the cutting process by the user rotating the handle. In addition, the materials used provide little friction to allow the handle to slide easily in the V-shaped fulcrum.
