ABSTRACT:
The present invention provides for an article and method for an improved weed trimmer cover that prevents unwanted projectile and debris distributions. A preferred embodiment of the weed trimmer comprises a domed guard structure that encompasses the effective cutting range of a prior art weed trimmer. Alternative embodiments may comprise elements that protect only portions of front, side and rear cutting areas. Embodiments of the invention also allow a user to lift up a cover element to allow close work among obstructions. Embodiments of the present invention also improve the performance of prior art weed trimmers by increasing cutting performance and preventing flexible materials from wrapping about the cutting elements and shafts.
