Eagle Manufacturing Company
The Eagle Manufacturing Company of Appleton, Wisconsin first entered the farm equipment market in 1906 with a 32 horsepower (24 kW) tractor. They returned to the marketplace several years later, in 1929 offering a 20-35 Model E. Based on a two-cylinder traction engine design, the engine measured 8.00x9.00 inches in bore and stroke. A truly massive affair, it was rated at 20 drawbar horsepower and 35 belt-pulley horsepower. Eagle also built its Model H alongside the Model E from 1926 to 1930. With an identical 8.00-inch (203 mm) bore to the Model E, but a 1.00-inch (25 mm) longer stroke at 10.00 inches, the Model H created a brawny 40 horsepower (30 kW) at the drawbar. Eagle was one of the first tractor manufacturers to use a 6-cylinder engine. It switched from 2 cylinders to 6 cylinders in 1930.
