Abstract: A soil tiller assembly for plowing multiple independent rows of soil includes a frame and attached thereto a coulter, a pair of tiller discs, a pair of secondary coulters, and a tilling assembly including a tiller wheel. The perimeter of the tiller wheel has a plurality of blades attached thereto, and the blades are rotated in the direction opposite each of the other blades described above. The soil tiller assembly is used to build up separate rows of plowed soil, which will prevent overtilling of the soil. Furthermore, the preferred method of operation allows the operator to build multiple rows of soil, delay contact of the soil for several months, and then plant seed in the rows of soil, such that the soil will receive required nutrients during the period of delay while further limiting erosion.
