Abstract
Soil conditioning apparatus having a main frame, and means coupled to the main frame for cutting and loosening compacted soil to prepare a seed bed and rooting environment, including a subsoiler coupled to the main frame and angled to be pulled downwardly into the earth below the surface to prepare a better rooting environment and seed bed and to increase water infiltration. A slot filler wheel is coupled to the main frame for filling voids in the soil left by the forward motion of the subsoiler therethrough; the slot filler wheel is mounted adjacent to and laterally spaced from the subsoiler so that a portion of the slot filler wheel may extend forwardly of the trailing face of the subsoiler. Also, the slot filler wheel may be mounted to lie in a plane of rotation which extends downwardly toward the subsoiler and inwardly toward the slot formed behind the subsoiler. One or more rotatable seed bed implements may be mounted alongside the subsoiler to contain soil displaced by the subsoiler within a defined bed region.
