ABSTRACT:
An agricultural subsoil implement is described having a V-shaped tool bar with a plurality of subsoiler tools affixed thereto at desired intervals for projecting forward and downward through the topsoil into the subsoil. Each tool has a leading edge that extends along a parabolic curve to provide a positive downward draft without substantially increasing the pull required to draw the tools through the soil. The implement has two independent wheel assemblies mounted on the tool bar intermediate the apex and the outer ends. Each wheel assembly has a standard that exists upward to receive a hydraulic jack. The hydraulic jacks are operatively connected by a flow divider to uniformly apply equal amounts of fluid to each jack. A wheel strut extends forward and downward from the tool bar to axles that carry dual pneumatic tires. The wheel assemblies are aligned with corresponding subsoiler tools with the struts directly over the tool shank so that the shank tip may be raised between the tires.
