Allis-Chalmers' history is as rich as the Persian orange paint that graced its farm tractors for nearly six decades. From its beginnings in the farm equipment business in 1914 to its rise as the third largest tractor producer in sales in 1936, Allis-Chalmers has been known for innovations in design and sales and distribution. This is a one-of-a-kind book for collectors, historians, and tractor enthusiasts, providing a detailed history of the company's legacy along with over 100 spectacular photographs. Illustrations include black-and-white historical photos, colourful period advertising artwork, and contemporary colour photographs of collectible tractors. The book covers all models from 1914 on, including the Monarch and Advance-Rumely models. Peterson and Grooms also discuss Allis-Chalmers' various acquisitions and the mergers, plus the current ownership by FiatAgri of Italy.
