ABSTRACT:
A large moldboard plow utilizing a multi-piece backbone or main frame connected by a hinge or hinges and a floatation land wheel or wheels. The hinge or hinges being arranged such that a uniform interval is maintained between the last plow bottom on the front section and the first plow bottom on the rear section. The floatation wheel follows the contour of the land which causes flexing of the backbone at the hinge resulting in uniform depth of all bottoms. The hinge or hinges are located to provide a practical line of draft for the rear section thus maintaining balance of the entire unit.
