ABSTRACT:
Tools for trimming excess vegetation from growing plants include inner and outer coaxially positioned, relatively rotatable cutter blade assemblies which establish an interior volume for receiving a plant to be trimmed. Excess vegetation from the plant which extends outwardly of the interior volume established by the cutter blades will therefore be severed upon relative rotation being effected therebetween. Most preferably, the inner cutter assembly includes sets of elongate cutter blade members whose having tined ends which may be partially embedded in the soil surrounding the growing plant to be trimmed. The outer cutter assembly is mounted for free movement both rotationally and longitudinally regarding the inner cutter assembly, and is most preferably connected to a motorized source of power (e.g., a conventional hand-held electric drill). The tined ends may therefore be embedded in the soil surrounding the plant so that the plant occupies the interior volume defined thereby and so that the inner cutter assembly remains stationary during the trimming procedure. The outer cutter assembly may then be sleeved over the inner cutter assembly, and rotated (e.g., by operation of the electric drill attached thereto) to thereby cause the excess vegetation extending outwardly from the interior volume to be severed.
