ROFlMAO! I wouldn't be surprised if Purdue U. hasn't tried something like that. last year, rumor had it that one of the larger operators near my farm was fiddling with his GPS stuff while running beans at night. He planted his 930 grain table into a fence line! A buddy of mine in NY state helps run beans. He uses the GPS to map out the rocks. Then the software creates the most efficient path for you to pick up the rocks after harvest.
