JD 40 Serial Numbers John Deere 40 Serial Numbers Here are the serial numbers for the various styles of John Deere 40 tractors. Please note there are two sets of numbers. One set indicates the calendar break of the serial numbers - tractors built from January 1 to December 31 of that year. The other set indicates the model year breaks of the serial numbers - tractors built from August 1 to roughly July 15 of the following year. Similar to the way cars are built, the model year of the tractor was usually introduced prior to the calendar year. So a 40 built in October 1954 is really a 1955 model.
