Abstract
The apparatus for tilling soil provides a significant reduction in energy consumption. The apparatus includes one or more sweeps which are effective for subtilling the soil as it is moved therethrough. One or more tillers are provided ahead of the sweeps, sufficiently near the path of travel of the outermost ends or tips of the sweep blades so as to disturb or loosen the soil directly in the path of the ends of the blades. By positioning the tillers relative to the sweep tips in this manner, energy consumption may be significantly reduced in comparison to subtilling devices having coulters or other tillers positioned ahead of the center of the sweeps.
