Abstract
A primary tillage implement having a plurality of chisel plows mounted in lateral spacing on a forward bar, also has a plurality of disc levelers mounted on a rear bar. Each disc leveler assembly is laterally spaced from and centered between the paths of adjacent, leading chisel plow shanks and includes a pair of discs angled outwardly to move some of the soil from the ridge formed by adjacent chisel plows to the furrow formed by an associated chisel plow. The discs of a pair are staggered and spaced laterally apart to leave a narrow band of loose soil in the ridge between the discs which falls into the shallow grooves formed by the discs after they pass. Soil is thus laterally displaced from the ridge to adjacent grooves to level the soil.
