ABSTRACT:
A hand-held rotary trimmer comprises a removable multi-piece shroud for covering a drive shaft and rotary cutter of the trimmer. The shroud includes an opening for feeding vegetation to the rotary cutter and an expulsion duct extending in a direction generally tangential to a rotational direction of the rotary cutter. In the preferred embodiment, the shroud includes three pieces formed of molded plastic. A first piece of the shroud has a hood portion and a first half-collar portion integrally formed with the hood portion. A second piece of the shroud has a second half-collar portion removably attached to the first half-collar portion of the first piece for releasably clamping the shroud on the trimmer housing and a flange portion integrally formed with the second half-collar portion and arranged to be flush against the hood portion of the first piece. A third piece of the shroud is ring-shaped and attaches to a bottom end of the hood portion, thereby defining the area of the opening through which vegetation is fed to the rotary cutter. Each of the three pieces is preferably formed of lightweight molded plastic to minimize user muscle fatigue.
