We just took a tour thru northern Indiana. So many nice old tractors for sale. Some restored. Some originals. All right out there next to the road, with for sale signs. Farmalls, Massey Fergusons, Case, John Deere. Plenty of others back in the barnyard. I think you could maybe talk the owner into selling.
Old tractors are beautiful things. The new ones are good. But the tire size is what you need. Go for a 2WD, with large rear wheels. Older ones are the ones that have what you need for the right price.
