Restored John Deere 4010

I spotted this beautifully restored John Deere 4010 in Roodhouse, IL.  The 4010 not only rescued Deere and Company from sluggish sales of their 2 cylinder tractors, it brought many innovations to the farm tractor world.  How far ahead of the competition was the 4010?  I remember as a fairly young kid going to a tractor pull at Belle-Clair Speedway in Belleville, IL and the only tractors in the heaviest weight class were John Deere 4010's.  Nothing else could compete.  Green Magazine has this to say about the 4010 and successor 4020.
