When did John Deere and Cyrus McCormick Split?
John Deere and Cyrus McCormick were never together. They were rivals of each other ever since McCormick invented the mechanical reaper(combine) and Deere & Company were trying to invent their own(John Deere was himself dead at this time). They were even more rival companies when McCormick merged with other companies to for International Harvester, a huge blow for Deere as they still are strong competitors today.
