Abstract
A lawn mower includes a housing having a top wall portion and a generally vertically extending side wall portion. A plurality of wheels attached to the housing to allow the housing to roll over a surface to be mowed. An engine mounted atop the housing rotatably drives a shaft extending through the housing. An elongate blade attached to and rotatable with the shaft has a central portion and a pair of end portions, with at least one of the end portions including a cutting edge for cutting vegetation disposed inside of the housing to a first length upon rotation of the blade. A pair of line trimmer assemblies are attached to the blade to provide a pair of filament lines which extend radially outside of the housing to cut vegetation disposed outside of the housing to a second length upon rotation of the blade.
