720 row crop diesel

The 720 row crop diesel tractor was a high production unit. Some of the later production were built with 24 volt direct start. Our 720 still has the pony motor. Our 720 came from Ohla, Manitoba. It was an interesting machine as the fellow we bought it from preferred the looks of a 730 to that of a 720 and had changed the sheet metal on this tractor.So we bought it with both sets of sheet metal. We changed it back to a 720 when we got it home. The serial number on our 720 diesel row crop is 7221950 making it a 1958 model. It has the John Deere square front axle.
