Welcome to the Boards.

Machine serial number tag breakdown using the 350 Introduction from the JD 350 Parts Catalog:

SN = serial number
T = Tractor
4 = JD350
F= Crawler - Dozer
3 = Diesel
D= (Transmission) Sliding Gear with Reverser

Serial number: 101129 (This number falls in the 1969 build range using the serial number list on this site’s FAQ board)

There should be a T at the end of the 6 digit serial number which stands for the Build location which was the John Deere Dubuque Works.
