I just recently purchased a John Deere 6620 Titan II Combine.
The John Deere website shows the Serial # running from 000001 to 611,xxx. Other sources on the web seem to indicate these Combines were made between about 1979 and the late 80's.
My Serial Number 610,123. Does anybody know how to determine the year of manufacture??
Deere 6620 Titan II Combine Year?
