Abstract:
A lawnmower blade comprising:an elongated planar bar, said elongated planar bar having a center aperture such that said elongated planar bar is adapted for coupling to a drive shaft of a lawnmower, said elongated planar bar further having a generally arcuate first cutting edge, said first cutting edge extending along a curved portion of a first side edge of said elongated planar bar proximate a first end of said elongated planar bar to a distal end of a straight portion of a second side edge of said elongated planar bar; said elongated planar bar having a second end, said elongated planar bar further having a generally arcuate second cutting edge, said second cutting edge extending along a curved portion of said second side edge of said elongated planar bar proximate said second end of said elongated planar bar to a distal end of a straight portion of said first side edge of said elongated planar bar; said center aperture having a center axis aligned with a longitudinal axis of said elongated planar bar; a first fan portion having a pre-determined length for creating an updraft when said elongated planar bar is in use, said first fan portion extending from an upper surface of said elongated planar bar at a predetermined angle, said first fan portion being positioned proximate said distal end of said straight portion of said second side edge of said elongated planar bar; said first fan extending from said upper surface of said elongated planar bar at about a 33 degree angle from said upper surface; said first fan portion further having a distal edge, said distal edge of said first fan portion being positioned in a plane transverse to a plane in which said elongated planar bar is positioned and in which said straight portion of said second side edge lies; said elongated planar bar having a second fan portion of predetermined length for creating an updraft when said elongated planar bar is in use, said second fan portion extending from an upper surface of said elongated planar bar at a predetermined angle, said second fan portion being positioned proximate said distal end of said straight portion of said first side edge of said elongated planar bar; said second fan extending from said upper surface of said elongated planar bar at about a 33 degree angle from said upper surface; said second fan portion further having a distal edge, said distal edge of said first fan portion being positioned in a plane transverse to a plane in which said elongated planar bar is positioned and in which said straight portion of said first side edge lies; said elongated planar bar further having a first storing aperture, said first storing aperture being positioned proximate said first end of said elongated planar bar; said first storage aperture having a center axis aligned with a longitudinal axis of said elongated planar bar; said elongated planar bar further having a second storing aperture, said second storing aperture being positioned proximate said second end of said elongated planar bar; and said second storage aperture having a center axis aligned with a longitudinal axis of said elongated planar bar.
