Abstract: A chisel plow including a landside attached rearwardly of the chisel shovels. The landside is disposed to extend generally fore-and-aft and is disposed laterally outward to one of the lateral edges of the chisel shovel. As the chisel plow travels forwardly through the soil, each chisel shovel forms a fore-and-aft furrow defined by opposing furrow walls cut by the lateral edges of the chisel shovel. The landside bears against one of the furrow walls to counteract forces which tend toward an overcutting or undercutting condition. Structure is provided to allow the selective mounting of the landside to be disposed laterally outward to either of the lateral edges of the chisel shovel to control overcutting or undercutting. This results in improved functional performance of the entire chisel plow implement by allowing it to maintain its proper width of cut.
