I have an old MM Tractor that was on my place when I bought the farm. Someone looked at it and told me he thought it is a 1946 year. I don't know anything about them but the engine is not frozen up. When I pull it in gear, the engine turns. It has had a can over the smoke stack when I first got it so it looks like someone was trying to protect the engine. Does any one have a clue as to what it might be worth? A couple different people have ask if I want to sell it but I don't want to give it away. If anything, it looks good sitting at my front gate.
