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.

13. A method for cutting vegetation on a surface, the method comprising:
-
providing a lawn mower having a housing with a peripherally extending side wall, wheels attached to the housing, a power source mounted on the housing, and a cutting blade rotatably driven by the power source to cut vegetation to a first length upon rotation of the blade; mounting a line trimmer assembly to the blade, the line trimmer assembly including an elongate filament line, the filament line extending radially beyond the side wall of the housing to cut vegetation to a second length upon rotation of the blade, said second length being greater than said first length; and rotating the blade such that the blade cuts vegetation located inside of the housing to said first length and the filament line cuts vegetation located outside the housing to said second length.
