I had to get something out from the back of the barn, and that meant pulling out all of the classic tractors…  Since I had them all out on a cold wintery day, I thought that would be a good opportunity to get a quick little video of them running.  What you can see is a 1939 John Deere A, 1947 John Deere A, 1949 John Deere B, 1963 John Deere 2010, and 1972 John Deere 4020.
