If you bypass the safety sensors, most 10 year old tractors already has everything else needed to drive a preprogrammed route around the field. You can buy kits relatively cheap to add this to much older tractors, not much skill needed that a farmer wouldn't have. The hard part stopping the tractor when done if a mine doesn't destory it.

As an employee of John Deere (not speaking for my company) I normally strongly discourage bypassing safety sensors, but this is one application where I can support the idea.
