This 720 tractor had the serial number "7200000". It was the very tractor used in the Nebraska horsepower tests - the tests that provide the "official" horsepower specs for the entire model line. Interestingly enough, the tractor has been in the same family its whole life - they bought it from Deere a couple years after it was produced, and used it up until the late 1990's, when they decided to restore it.
