What the company or idea is
John Deere is an American corporation founded in 1836 in Illinois, manufacturing agricultural and heavy equipment, with origins in the 1837 self-scouring steel plow.
How it actually makes money
John Deere makes money by manufacturing agricultural machinery, heavy equipment, forestry machinery, diesel engines, drivetrains, and lawn care equipment. It also provides financial services.
What works
The self-scouring steel plow worked because it solved a specific physical problem — sticky prairie soil — with a reproducible material solution. It enabled farming on previously uncultivable land and aided migration into the Great Plains.
What does not
The sources do not establish revenue, profit, market share, valuation, headcount, or any post-1843 business model details. They say nothing about software, autonomy, data, subscriptions, or modern digital strategy.
What to take from it
Its early advantage was mechanical: a polished steel surface that shed soil. Its scaling was infrastructural: water-powered factory production by 1843. Its financial services came later — the sources do not date them.
Is it worth your time
Yes — if you are studying how industrial manufacturing, material innovation, and embedded finance co-evolved in US agriculture over nearly two centuries.
