John Deere is America's favourite farm tractor - and the General Purpose tractor is the most popular John Deere. These affordable tractors from the first "Poppin' Johnnys" to the Model M, allowed the small farmer to convert from animal power to tractor power - and in the process, changed the way America farmed. 80 beautiful colour photos combine with detailed text to chronicle the development of these 2-cylinder workhorses. Millions of these important and collectible green and yellow machines were produced from the 1920s through the 1960s including models D, GP, A, B, G, L, H, and M. 40 black & white and 80 colour illustrations.
