ABSTRACT:
A farm implement adapted to be coupled to the front of conventional tractors for pre-cutting or scalping old levees. A rigid, box-like frame is secured generally transversely upon the front of the tractor. The frame supports an elongated, rigid channel mount extending generally perpendicularly with respect thereto. An elongated, rigid stanchion may be coupled to the channel mount to elevate a first hydraulic cylinder attachment point at a desired elevation above ground. A plow assembly includes a pair of rotatable, angularly disposed forwardly projecting cutting discs rotatably secured to a central frame, and an elongated rigidly upwardly extending strut terminating at its top in a second point for connection with a hydraulic cylinder. Rigid strut guide means are secured about the channel mount at a desired elevation, sandwiching the stanchion therewithin. The strut guide means includes a rigid box which receives the plow assembly strut and permits axial displacements thereof, while resisting or preventing lateral or torsional displacement. A hydraulic cylinder may selectively move the plow assembly into or out of engagement for the levee to be destroyed.
