ABSTRACT:
A blade assembly is provided for a lawn mower which includes first and second fan blades to maintain the interior of the blade housing free of accumulated grass clippings as occur when mowing damp or wet grass. The blade assembly includes a conventional grass cutting blade and two axially spaced and radially displaced fan blades which are affixed to the engine shaft, above the cutting blade. The fan blades create sufficient turbulence within the housing to prevent grass accumulation, thereby improving the ability and efficiency of the mower.
