Aermotor engines at Midwest Old Threshers Reunion in Mt. Pleasant, Iowa.
A line-up of fluted-hopper Aermotors at last September’s Midwest Old Threshers Reunion in Mt. Pleasant, Iowa. Left to right: George Eddy, Centerville, Iowa; Mike Dietz, Waverly, Neb.; Mark Churchill, Coon Rapids, Minn.; Barry and Zachary Tuller, Three Way, Tenn.; and Dean Harris, Parsons, Kan. All of the engines shown here are 2-1/2 hp models except for the two at far left, each of which is a 5 hp model.
Mark Churchill’s 2-1/2 hp Aermotor (left), and Barry Tuller’s (right).
An 8 hp “sausage hopper engine.”
The 2-1/2 hp fluted-hopper Aermotor engines were manufactured from about 1912 to about 1926. The 2-1/2 hp model is easier to find than the 5 hp, and it’s more desirable, in part because it’s easier to transport: The 2-1/2 hp model weighs 600 pounds; the 5 hp, 1,000 pounds.

From any angle, the fluted-hopper on the Aermotor engine is a unique configuration.
