I can remember my grandfather over half a century ago discussing with some other small farmers the merits of round bales versus square bales. They were part of an equipment ring and shared equipment that would have cost to much for any of them to buy on their own. They had a small Allis-Chalmers Roto-Baler and were thinking of buying a newer baler to replace it. They ended up buying a square baler and keeping the round baler too.
