Abstract: An improved trimmer guard (15), for use with a trimmer (16) having a motor (18), a head (19) and a shaft (20), comprising a mounting assembly (23) configured to mount to a trimmer shaft, a frame (24) supported by the mounting assembly and a foldable skirt (25) supported by the frame. The frame and the skirt may be configured and arranged to move from a first folded position (26) to a second expanded position (28). The skirt may comprise a material selected from a group consisting of polyethylene film, woven polypropylene, woven nylon, canvas and neoprene. The support frame may comprise a first arm (29) extending from a mounting assembly and a second arm (30) extending from the mounting assembly and the first and second arms may be pivotally connected to the mounting assembly. The first and second arms may pivot from a folded position that is substantially parallel to the shaft outwardly to an expanded position that is in a plane substantially perpendicular to the shaft.
