John Deere: A History of the Tractor: Excellent photo history.
From the publisher: "No tractor has achieved a more iconic status than John Deere. It's simple, two-cylinder tractors proved just the reliable, dependable tool the early 20th century American farmer needed to take the great leap from farming with animals to mechanized farming. Although a late comer to the motorized farming industry, today John Deere's two-cylinder tractors are the most sought after collector tractors in the world. Always a conservative company, John Deere stuck with its two-cylinder tractors into the middle part of the century, long after every other manufacturer had moved on to four- and six-cylinder tractors. Yet these simple, noble machines continued to serve their market. When John Deere entered the multi-cylinder fray, it did so with the most advanced, groundbreaking machines ever built — the New Generation tractors. These tractors set the trends for all subsequent tractor development through the latter half of the 20th century." Link
