Abstract: A plow and disc combination machine which utilizes a bridge hitch type frame which is built in the same order as a highway bridge which enables the plow to have clearance so that a disc gang mounted under it and movable by hydraulics can be raised or lowered on the move. The fact that a bridge truss structure is utilized in the frame allows the discs to be movable over a wide vertical range and allows the subsoiler plow shanks to be used in the ground at maximum depth without the usage of the disc blades. The discs can also be lowered to cut material such as corn stalks as the plow is used.
