John Deere developed and manufactured the first commercially successful cast-steel plow. He sold his first copleted steel plow
to a local farmer, Lewis Crandall. This farmer spread the good benefits he obtained, using Deere's plow. This farming product was ideal
for tough soil of midwest and worked better that other plows of its time. By 1841, Deere was manufacturing 75 to 100 plows per year.
Deere's plows was such an important invention, that by 1955, his factory were selling over 10,000 units. This became known as "The plow
broke the plains." and is commemorated as such in a historic place in Vermont. Deer was not only an inventor, but also he was pushing
himself on making high-quality equipment. He once said "I will never put my name on a product that does not have in it the best that is in me."
Later as business improved, Deere left the day-to-day operation to his son Charles. Then in 1868, Deere incorporated his business as Deere
& Company. On the last years of his life, Deere focused most of his time and attention to civic and political affairs. He served as president of
the national Bank of Moline, as director of Moline free public library, and was a trustee of the first congregational church. As a political activist,
Deere served as Moline's mayor for two years. He died at home (known as Red Cliff).
