Thank you for listing this it is been helpfull. So since my model is T4F3D and serial = 038883T then according to this The JD350B units would have been produced along with the JD350C until the 3/152 engine stock was depleted, but the JD350B units changed over to the wet steering clutches used in the JD350C when the stock of dry-type steering clutch parts was depleted. However, there are some late JD350B's out there with wet steering clutches. We do not know the exact serial number of the last JD350B as a result. There is an overlap in 1975 where JD350B and 350C models were made concurrently.

The meaning of the letters csme from the JD350C manual section 1A3. At some point during the manufacturing of the 350B, they added a letter. Thanks to Digitup for sharing the relevent pages from his guide with us so we can determine what year a given machine is.Īdditionally, some model numbers contain an extra letter. 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. However, we do not know the beginning serial number in this new range.

So, there are some 350C units showing serial numbers in the 700000 range prior to number 723603. Sometime during 1985, the serial number scheme was changed and the new range started in the 700000 range. The main differences between the JD350B and JD350C are that the C went to a 3/164 CID engine from the 3/152 CID in the JD350B and that the JD350C changed from dry to wet steering clutches.
