john deere serial number lookup 2150 to find year

The northern dry clutch machines were filling up with moisture at a rate that was wrecking the machines. Thanks to Digitup for sharing the relevent pages from his guide with us so we can determine what year a given machine is. I'm making the reasonable presumption that the last serial number for any given year is one less than the starting serial number for the successive year. The guide as such only lists the beginning serial number for each year. The source of the data is from a farm equipment quick reference guide that's intended to assist dealers in determining the year and current market value of trade-in equipment. Just go with it, figuring on the usual reason of exhausting some factory parts stock in what is called a 'running change'. In 1984, the serial numbers jump to 700010, and I can't believe Deere made a couple hundred thousand 450D's in 1982! The serial number list says that the JD450D started in 1982 just past the serial number shown for the start of the JD450C 1983 production. The power went up all of 3 HP, so I really don't know why there was an overlap this time. The JD450B units changed over to the wet steering clutches used in the JD450C when the stock of dry-type steering clutch parts was depleted.Īgain, we have an overlap between the JD450C and the JD450D. The JD450B units were produced along with the JD450C until the demand for the non-turbo engine dropped off.

However, there are some late JD450B's out there with wet steering clutches.

Also, the JD450C changed from dry to wet steering clutches. The main differences between the JD450B and JD450C are that the C went to a 4/219 CID Turbocharged engine from the 4/219 CID normally aspirated engine in the JD450B. We do not know the exact serial number of the last JD450B as a result. There is an overlap in 1975 thru 1976 where JD450B and 450C models were made concurrently. Here are the serial numbers, by year, for the JD450 through JD450G models.
