Abstract:
1. A flexible, trimmer line system for cutting vegetation comprising a powered device providing rotary power at a power end; a flexible, line-trimming-head add-on attached to the power end of said powered device for rotation, said trimmer-line-head add-on comprising a protective base portion; a main trimmer head top portion having an upper side and a bottom side, the bottom side attached to said protective base forming a combined head top portion and base portion structure; and a series of at least two, separable, peripherally spaced, line holder parts attached to said upper side of said trimmer head top portion so that said line holder parts oscillate back and forth about respective vertical axes and located adjacent to the periphery of said trimmer head top portion spaced a hundred and eighty) (180° degrees apart from one another, said line holder parts having one or more line holder attachments capable of accepting and holding one or more respective folded-back, flexible, trimming lines in said line holder attachments when said base portion, said trimmer head top portion and said line holder parts, attached together as an integral unit, are rotated at a relatively high speed by said powered device, causing said trimming lines to move straight, radially out under the action of centrifugal force but allowing the trimming lines to move backwards due to impeding forces and then allowing each respective line holder part to oscillate back urging the trimming lines back toward a radial position.
