McCormick-Deering Model T-20 TracTracTor

The kerosene powered McCormick-Deering Model 20 TracTracTor was a upgrade of the 10-20 TracTracTor , but utilized the 10-20 engine, transmission and rear axle. The undercarriage and steering were upgraded so that none of those parts can be interchanged with the 10-20 TracTracTor. The Model 20 is easily identified by the straight fenders and smaller steering clutch housings referred to as "camel humps". The track rails were widened as were the sprockets, idlers and rollers. The air cleaner was moved to the side of the radiator from out in front. The Model 20 TracTracTor was manufacture from Sept 15, 1930 to May 1931 and superceded by the Model 15.
