I have a 550c John Deere dozer, with a serial number of 355685T. Does anyone know how to determine what year it is?

My book shows no 550C's. Just 550/550A/550B/550G's. By your s/n it's a 1980 straight 550. 1980 started with 340920-365417-1981 365418-377851 The 550's with leters started with #'s 700231 & up in 1983. Just listed what by book showed. Hope you didn't buy what you thought was a newer machine. HT

You are correct about no such thing as a 550C according to John Deere they never made such a thing only has the C indicated on the serial number but if you go to Machinery they have several 550C's listed for sale. Just my .02 worth

Thank you for contacting Machinery Trader regarding the Deere 550C model. I did some research and contacted John Deere and you are correct, there is no such model as 550C. I have changed those listed on our site to just Deere 550. Thanks so much for your input. We appreciate your insight.

I am currently looking at a JD Dozer to purchase. On it's tag it says JD500C. The serial is 329356T. I presumed from the tag it was a 550C, but the above discussing has me thinking otherwise.

Any idea what year this beast was built?

The C stands for the C frame holding the 6 way blade.It would have a L for loader.Its just a plain 550.If it was a 550b The s/n would read 550BC
