<p num="1"><br/><br/>A trimmer line, hook disk system forming a line trimmer head (e.g., Figs 10 '||to_char('&')||'amp; <br/>10A, 19 '||to_char('&')||'amp; <br/>20) for attaching to a powered, rotational device (Figs 11-16) to provide a <br/>line filament grass <br/>cutting/weed-removal action. The trimmer head preferably includes a circular, <br/>protective, bottom <br/>base (D2/60/160), a main trimmer head top (D3/D30/130), the two forming a disk <br/>shape, and a <br/>series of peripherally spaced, line holders; with these three basic elements <br/>fastened together for <br/>ultimate attachment to the powered 31 device. Ten exemplary line holder are <br/>shown (Figs. 1-9B),<br/>with most allowing oscillating (O) motion in their attachment to the trimmer <br/>device (D1), <br/>allowing the lines to move backwardly when contacting a relatively hard item, <br/>and/or some fixed <br/>(F). A "broom" embodiment is disclosed (Fig. 17). When used, flexible line, <br/>e.g. of nylon, is <br/>inserted in (1) and held (2) by the line holders preferably using hook or hook-<br/>like line <br/>attachments.<br/>
