ABSTRACT:
An earthworking implement mounted on a three-point hitch of a draft vehicle with a hitch assembly. The hitch assembly has L-shaped members mounted in clamps secured to a main transverse beam. A plurality of parallel linkages movably connect a transverse tool bar to the beam. Row guide units having longitudinally aligned guide wheels and furrowing tools are mounted with clamps to the tool bar. Earthworking tools are mounted with clamps to the tool bar. In one form, the earthworking tool is a blade sequentially moved into and out of the soil with a lifting wheel to dig water and snow holding basins or trenches in the soil.
