1926-1930

In the late 1920s, Lauson came out with a 20-40 model designed especially for the thresherman. It used a 4 3/4 x 6-inch engine similar to the older 15-30 model, but the speed was increased to 1200 RPM. The unique canopy was a characteristic feature of Lauson tractors for several years. Nichols & Shepard Company sold Lauson tractors for a few years after they quit building their own outfit. A 20-35 tractor was offered at the same time as the 20-40, but the biggest difference between the two was a 1040 RPM crankshaft speed on the 20-35, compared to the 1200 RPM used in the 20-40.
