Abstract
A filament trimmer includes a rotatable trimmer head having an outwardly extending filament. The trimmer has an upper handle that the operator can grip to operate the trimmer in either a trim mode or an edge mode. In the trim mode, the filament extending outwardly from the trimmer head is positioned in a generally horizontal cutting plane, while in the edge mode the trimmer is reoriented such that the filament is positioned in a generally vertical cutting plane. The upper handle of the trimmer includes dual triggers for selectively starting and stopping rotation of the trimmer head. One trigger is actuated when the trimmer is operated in the trim mode and the other trigger is actuated when the trimmer is operated in the edge mode.
