I just bought a "new" book off of Craig's List for $10. It's titled "John Deere - A History of the Tractor" by Randy Leffingwell. About 400 pages filled with pictures and the history of John Deere tractors.
John Deere - A History of the Tractor
I read a few chapters so far - very interesting book. Makes me want to go out and find myself a two cylinder Johnny Popper. I have been wanting a smaller one, i.e. nothing bigger than a B, perhaps a H, or a M or a 40. I may have to go find one and convince (beg) the wife for one.
