Abstract:
1. A lawn perforating tool comprising: (a) an elongate handle portion having a proximal end and a distal end; (b) a working head transversely mounted to the distal end of said handle portion, said working head having at least one axle; and (c) a plurality of perforating wheels rotatably disposed about said axle, each of said wheels comprising a central bore defining a bore axis and a plurality of wedge-shaped radial arms extending from said central bore, positioned at an angle relative to a plane that is normal to the bore axis, and defining angular spaces therebetween, wherein said radial arms are comprised of a widened base that tapers in three dimensions to a sharp-edged spike, wherein said spike is capable of slicing grass and penetrating soil to create an initial puncture and said base is capable of subsequently plowing the puncture, pushing up and loosening adjacent soil to widen the perforation, further wherein said arms and wheels coordinate to yield an array of sideways-extending lawn perforations having an overall depth ranging from 1 to 2 inches and that narrow from a wide mouth to a small niche hole so as to be suitable for receiving grass seed and promoting germination.
