Right B stands for the model and C stands for the C frame carring the 6 way blade.I saw one at auction, 450C instead of CC it was 450CJ.I ask the dealer and he looked it up J ment it was built with no blade.just draw bar.Ofcourse CL ment loader.I just saw another guy this week near binghamton NY trying to pass off his 450BC as a 450C.Anyways to my main point !I just bought a trade in.450CC s/n 389114.I looked up on list it showed 1982. I cant help think if JD gave up on the 2cyl idea a decade earlyer sales would have been better also but who knows maby not !!.Digitup. There was a reason John Deere went wet clutch but they were nearly the last on the band wagon and they did this slower than most But John Deere did this a lot over the years. We never realy went back to the 450s after that. We didn't have a 450C for 4 or 5 years after that and I had my first 550 as they came out just afterwords we got a 450C this was dads last 450 and yes it was a C not the best Deere dad ever owned It got traded on a new 550A within 3 years. Harvester and Cat were selling wet clutch and Deere was down on sales with new tecnology.When we got ours I think the Cs were just going to hit the dealers. With condensation / cooler weather and high humidity working against them as well as International and Cat having new oil bath clutchs putting Deere on the looseing end this is when my dad got the last of the 450Bs and it was wet clutch no turbo and a B on the side of it. 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.
