Many N's were mutts as when the engine blew and a replacement was installed, or parts broke and were swapped out with used ones from a parts tractor etc. Yes, it makes it difficult to determine exactly what you have unless you know the previous owner and/or the tractors' history. I ususally go by the s/n first and when that is unreadable, I go the engine casting code on the block starter pocket. Remember the s/n and casting code are all part of the block which was cast as one. The date is just the date it was cast, not the actual build date. Add at least another month to the casting code for the build date. Serial numbers got hand-stamped on the blocks AFTER they passed Quality Control.
