John Deere was a relentless designer. John M. Gould, one Deere’s partners, recalled his deliberate approach: “Mr. Deere in his early experience would make a plow, then go out and give it a trial and if it did not work, he would take it to pieces and change the shape and try it again, and with a good deal of persistence, finally succeeded in getting his plows to scour. Mr. Deere was a natural mechanic.” His quest for perfection was life-long: Deere secured a patent for an improved plow when he was well past age 60.
