Abstract
The subsoiler has shank assemblies which are designed to cut a thin, clean slice in the soil without frontal upheaval forces that would cause eruption of the soil in a turbulent manner ahead of the shank line. The soil lifting components at the bottom of the shank are configured to produce generally laminar soil flow over and around their lifting surfaces so that the upwardly and outwardly directed fracturing forces occur behind the leading shank line in a readily controllable manner and without disturbing residue and other materials on top of the ground. The subsoiling profile at the bottom of the shank may be varied by interchanging variously configured points and caps which are securely but removably secured to the shank. An alternate embodiment provides adjustment of the profile presented to the soil by having a portion of the component angularly vertically adjustable to vary the angle of attack of its lifting surfaces.
