Abstract
A moldboard plow that is made in two sections which are hinged together about a horizontal pivot axis, so that the rear section of the plow can pivot about this horizontal axis relative to the front section to permit the plow to follow ground contours. Such hinged plows are useful where the present day large plow assemblies are utilized. The hinge assembly also includes structure for reducing the overall width of the plow for road transport. The present hinged plow is supported at four support points controlled by hydraulic cylinders connected and controlled to insure that when the plow is lowered into the ground the shares will enter the ground at a favorable angle for penetration.
