I am thinking of replacing my well used MF 235 with a new 231S from a local dealer here in SC? I am looking for advice on how these tractors compare performance-wise and if there are other makes and models I should consider. I was quoted a price of 12,900 for the 231s and would like to stay in that range. Anyone have any expereince with the 231S. Any advice or info is appreciated! Thanks!
