We are in the process of plowing and replanting a couple acres of pasture. Its been 60-70 years since it was last done. Its clay soil and thick heavy sod. We used our Farmall M pulling a john deere 44 plow for the bulk of it. The ends of the field were cleaned up with our Farmall SC with a 2-point single bottom plow. Once the plowing was finished we ran a disc over it and then tilled. The next step was to level by pulling a pair of H-beams over the tilled ground.
