That has been my experience as well. Can't tell you how many field cars I have hooked a chain to and by the time they are close to the trailer everything is moving. I have had the dreaded groove in the pads holding the drum on but it is pretty rare. If you yank on it enough it's going to bust free. Hope he gets it. It's just brute strength against brute strength at this point. Remember his Mom put a deadline on moving it so he is under some pressure if he wants eat I think.
