ABSTRACT:
An apparatus for cutting, trimming, and edging vegetation along driveways, sidewalks, and the like; around trees, shrubs, and like landscaping; and adjacent fences, walls, posts, and the like by rotation of a non-metallic cutting line in a cutting plane substantially perpendicular to the axis of rotation. The apparatus includes a drive motor positioned in a trimmer housing at one end of an elongated handle and adapted to rotate a driven shaft and a spool member connected thereto. The spool member has a storage of non-metallic cutting line member coiled thereon with a non-coiled portion thereof extending from the spool member and through an aperture in a wall of the trimmer housing. The spool member may be moved longitudinally of the driven shaft against the resistance of a resilient member and turned relative to the driven shaft to thereby adjust the amount of the cutting line member extending through the aperture in the one wall of the trimmer housing.
