ModelThe McCormick-Deering 10-20 TracTracTor, International Harvester's first production crawler, was basically a tracked conversion of the 10-20 wheel tractor. The crawler was steered by means of individual steering clutches and brakes for each track. The external clutches were contained in dome-shaped structures in the driving compartment, structures which came to be nicknamed "camel humps". Steering levers protruding from the domes could be pivoted upward so the tractor could be driven from a standing position. Other distinguishing features of the crawler were the larger rear than front sprocket, causing the top of the track to be slanted, and the air cleaner placed in front of the radiator. The 10-20 TracTracTor was superseded by the McCormick-Deering Model 20 TracTracTor which has smaller camel humps, straight fenders and completely revised under carriage.
