North America’s prairies once stretched from the foothills of the Rocky Mountains east into western Ohio, a staggering 1 million square miles or more of native grasslands that covered a third to nearly half of our country.
But what took millennia to develop disappeared in only half a century. The transformation began in 1833, when John Lane Sr. created the polished-steel, self-scouring plow, which could penetrate heavy prairie soils. A fellow blacksmith then improved upon Lane’s original design and marketed the new plow aggressively. That second blacksmith was John Deere.
