Abstract
A planar, turf cutter blade formed from either high carbon or stainless steel has planar cutting teeth that extend radially from the periphery of a central part of a planar disc in which a centrally located hole is formed. A turf aerator that uses the turf cutter blades aerates turf by slicing or cutting turf and does not punch holes into the turf.
