Abstract: A guard for a power trimming device of the type having a rotating cutting element partially enclosed about a short arcuate extent by a housing is formed from a rigid bar having a generally circular configuration with an open front portion formed by outwardly flared ends. A plurality of transverse apertures extend through the bar opposite the open front portion and receive threaded fasteners which secure the guard to the housing. The front portion of the guard allows trimming of brush and other vegetation, but protects fence posts, tree trunks and the like from damage through contact with the cutting element. The guard also provides an additional protection against injury to an operator. In a second embodiment, a compound adjustable bracket is utilized to secure the guard to the trimming device.
