ABSTRACT:
A turf reconditioning apparatus adapted to aerate and relieve the compaction of the soil, and comprising a plurality of cutting discs disposed along a supporting drive shaft, and with each cutting disc comprising a plurality of curved blades defining a sharp point at the remote free end thereof. The speed of rotation of the discs is coordinated to the forward movement of the apparatus whereby the point of each blade enters the ground substantially vertically to thereby reduce the power consumption and minimize wear along the side edges of the blade. The curved nature of the blade further serves to lift some of the loosened soil from the slits formed in the ground to thereby provide a light top dressing of the removed soil. The curved blades may be efficiently cut from a rectangular plate by a process wherein no additional machining or finishing operations is required.
