ABSTRACT:
A main frame is secured to a tractor for towing wherein the main frame is tilted as the tractor tilts to one side or the other of the path of travel A ball and socket joint suspends the tool bar by its central portion from the main frame so that the tool bar can swing from a position angling forwardly and to one side to a second position angling forwardly and to the other side The moldboards being fixed to an suspended below the tool bar cause the tool bar to rotate about its longitudinal axis automatically swing by gravity to upright positions for plowing, regardless of the tilt of the main frame. A latch plate latches the tool bar in its rotated position on the frame The tool moldboards have clamps which are adjustable along the length of the tool bar for adapting the plow to wide wheel or narrow wheel base tractors.
