You are right about the dates as far as Holt's first combines and the sale to John Deere go, but that is NOT what put J.D. into combine production or where Deere got their start in combines. Granted, Deere was somewhat a Johnny-come-lately, but their first combine debuted in 1927. Their Model No.2 was production-ready first, and Deere did not switch names just to make it look any different.
