ABSTRACT:
The instant invention relates to a lawn trimmer and an associated shield. The shield, in the preferred embodiment, is entirely formed from an impact resistant plastic. Additionally, the shield is defined by both an inner peripheral region and an outer peripheral region. An annular raised ring serves to define the boundary between these inner and outer regions. This shield is adapted to be removably secured to the drive shaft of a lawn trimmer. The interconnection between the drive shaft and shield is such that the shield can be rotated independent of the drive shaft. Such independent rotation of the shield allows the trimmer to be easily guided along either horizontal or vertical surfaces. Lastly, a spool of cutting filament is adapted to be removably secured to the drive shaft. The construction of the present invention allows for the removal and replacement of both the filament spool and the shield.
