ABSTRACT:
An earthworking implement mounted on a three-point hitch of a draft vehicle with a hitch assembly. The hitch assembly has members mounted in clamps secured to a main transverse beam. Two of these members include lower forward projecting portions and a third member therebetween has an upper forward projecting portion. The two lower portions are connected to a transverse bar, which is attached to the draft links of the three-point hitch. The upper portion is connected to the control link of the three-point hitch. These members are individually adjustable, whereby they may be adjusted to fit variations in structure of three-point hitches. A plurality of parallel linkages movably connect a transverse tool bar to the beam. Row guide units having guide and gauge wheels and furrowing tools are mounted with clamps to the tool bar. Earthworking tools, herbicide incorporators and seed planters can be mounted with clamps to the tool bar.
