I believe it would be faster with a roto tiller than to plow and then disc 2 or 3 times to prepare a seedbed. We sell the New Phoenix 40 inch for $1395 which is not going to be much more $ than a plow and a disc harrow. Ken Sweet
Afterthought: Has anyone ever plowed a 2 acre field with a 12 inch plow? How long would it take?
