Abstract
A trimmer blade assembly comprising a blade within a housing is provided. The housing includes a wall for propelling cut vegetation away from the blade assembly. The blade assembly may also include a ridge on the housing for further propulsion of cut vegetation away from the trimmer blade. The present blade cuts vegetation more efficiently since cut vegetation will generally be propelled away from the blade by the perpendicular wall and ridge.
