Abstract
A twisted shovel, for a chisel plow or similar implement, having a concave twisted surface. The concave surface maintains soil flow in the desired path as the shovel is moved forwardly through the soil. The soil displaced by the shovel is directed more effectively by the concave surface to one side of the shank to improve crop residue flow and incorporation, and the concave shape significantly improves the bending strength of the shovel over that of flat-twisted shovels of comparable width and thickness.
