ABSTRACT:
A soil aeration machine with a straight main frame being attached to a tractor via a three-point hitch. The main frame carries standards to which deep tillage knives are attached. A coulter is mounted directly in front of each knife to cut through the residue left on the surface, thus preventing build-up of residue on the knife. The knives have wings arranged so that when the knives penetrate deep into the soil, the wings slice through and lift the soil, creating macropores in the soil. As this lifting action occurs, no soil is displaced or turned, thus leaving all residue undisturbed on the surface.
