Talking with a guy at work, on his farm is a 70 diesel his sister in law owns. It came up in conversation when I said I'd like one some day. It's original. Runs and drives, but the big but is the pony motor block is cracked. He says it still runs, he just doesn't use it because they bypassed the coolant. He thinks I could get the tractor for a $1000 which I think could be a steal, but what am I in for with the pony motor. He thinks it maybe repairable as he thinks it may be only cracked outside since it still ran and no water was in the oil. This is very early stages of thinking about buying and I have not seen it.
