Full discloser I am more of a Case guy as I have several letter number tractors and a couple numbered ones as well, anyway I have figured out how to tell the year on a Case from the serial number, currently my son and I are restoring a Allis Chalmers WD-45 for a friend and would like to figure out what year it is. I found the serial number on the rear of the tractor on top of the housing to the right of the left brake cover. The serial number is : WD187708 with my Cases you subtract 4 from the first two digits, how does Allis Chalmers do theirs? and can I tell the year of the tractor from this number? I have found a couple charts online but nothing with this serial number on it? any help would be appreciated Thank you
