...MOLDBOARD PLOW, A REVOLVING CHAIR, A CIPHER FOR CODING MESSAGES AND A NATION...
When something new like this is born, something else must die. The self- scouring polished-steel moldboard plow is not going to expire totally. But history's chapter of giants in the earth with their plows is closing. It has been a glorious story, mistakes...

The genius was in the metal, sturdy and sharp enough to cut the strong, matted roots of the high-stemmed prairie grass and turn up the rich earth below for planting.

Last year only 6,300 moldboard plows were sold. Today John Deere does not even manufacture the plowshares and bottoms for the few thousand completed plows it sells.
