I have been considering getting another tractor for a while.Something a little more powerful than my TO20.I have my MF175 for bigger stuff but I had thought something in the size of a 35 would be nice. Plus you have live power on the later models. A friend of mine offered to sell me his nice 1961 MF35 deluxe gas burner for $2500.00. It needs nothing. Its a good looking tractor. I have also came across a pretty nice F40 for $3200.00. Is there really any advantages of one over the other? I am familiar with the 35"s but not the 40"s. As far as I know they are quite similar tractors arent they?
