A guard and guide for a powered, hand-operated, grass and weed trimmer having a trimming filament segment extending from a rotating spool thereof. The trimmer comprises an elongated tubular body having a forward end and a rearward end. The trimming filament segment and its spool are rotatively supported at the forward end of the trimmer body and are rotatable at high speed by operative connection to an internal combustion or electric prime mover. The guard and guide comprises an element having a forward portion having a substantially semi-circular peripheral configuration and an upwardly, inwardly and rearwardly extending rearward portion operatively attached to the trimmer body. This attachment is both adjustable and pivotable, the guide and guard being pivotable between a retracted inoperative position with its forward portion abutting the trimmer body and an extended operative position wherein the guard and guide forward portion extends away from the operator and overlies the forward portion of the path of travel of the trimming filament segment, extending slightly beyond the free end of the trimming filament segment to prevent contact of an object being trimmed about by the trimming filament segment to prevent damage to the object (such as a tree trunk) and to lengthen the useful life of the trimming filament segment.
A guard and guide assembly for a powered operator hand-held grass and weed trimmer having a trimming means in the form of a flexible, string-like filament segment extending from a spool of said filament and having a free end, said trimmer comprising an elongated tubular body having forward and rearward ends, means to rotatively and releasably support said spool and trimming filament segment at said forward end of said trimmer body, prime mover means mounted on said trimmer and operatively connected to said spool to rotate said spool and filament segment at high speed in a circular path of travel, said guard and guide of said assembly comprising an element having a forward portion with an arcuate peripheral configuration and an upwardly, inwardly, and rearwardly extending rearward portion, said guard and guide assembly including means to operatively attach said guard and guide to said trimmer body, said guard and guide having an operative position wherein its arcuate portion extends away from said operator and overlies the forward portion of said circular path of travel of said filament segment and extends slightly beyond said free end of said filament segment.
