Our son just bought a Ford tractor that has 2000 painted on the side. It is a 3cylinder diesel. There is no ID tag on it and the stamped area is hard to read and the model number is unreadable. The production code is 6K12B which I understand to be 1966 Oct 12 Day Shift. Then there is 176 stamped under this code and then there is 056265 in the serial number location. This number is not correct per all the sites I have seen. Does anybody have any idea's.
