I was coming across Wisconsin today, the center part where they grow potatoes and cranberrys. Driving down the road at 50MPH and saw a Oliver & plow for sale, going to fast to read the model number but it looked to be the size of an 806 International or a 4020 John Deere but it had a 3 bottom mounted plow on it? This is potato ground it's SAND, why would a big tractor like that only have a 3 bottom plow in SAND or MUCK, heck I did that with a Super M and was about ready to try it once with a John Deere A. What gives? Growing up we were the oddballs with the Farmalls, most everything else was John Deeres, Massey Fergusons a few Case and a handful of Allis Chalmers and our Farmalls.
