Abstract

A terracing plow for providing a shallow water terrace system for wetlands remediation. The preferred, embodiment of the present invention comprises a terracing plow having a frame having front and rear ends and first and second sides, the rear end having a generally medially situated, angled chute member having first and second scalloped coulter blades situated at the first and second sides of the frame, adjacent to the opening of the chute member. The coulter blades are situated on the frame at an angle in relative alignment with the adjacent chute wall. The preferred system of the present invention contemplates pulling the terracing plow via linkage to the front end of the frame through a shallow wetlands, in order to facilitate borrowing of the earth from the marsh bottom and building up same via the chute member, forming a terrace for the planting of marsh grass or the like thereon. An overhead crane may also be provided to suspend the medial portion of the plow frame, for adjusting the relative angle of attack and/or of the plow upon the marsh, depending upon the consistency of the ground.
