1910 Big 4 "30" Tractor

The Big 4 "30" was manufactured by the Gas Traction Company of Minneapolis, Minnesota, from 1908 to 1912. After the Gas Traction Co. was purchased by Emerson-Brantingham Implement Company in 1912, the Big 4 "30" continued to be manufactured without any modifications until 1916. It featured a 6 1/2 x 8 inch 4-cylinder engine, with cylinders and heads cast singularly. Normal engine operating speed was 650 rpm, and it developed 30 horsepower on the drawbar and 60 horsepower on the belt. The tractor weighed 22,725 pounds, stood approximately 11 feet tall (to the top of the canopy), and was over 9 feet wide and 21 feet long. Maximum speed was 2.22 mph in the field and 3.33 mph on the road. Some other advanced features were a Schebler vaporizing carburetor, a modern closed cooling system, high-tension Remy magneto, and forced lubrication. In 1916, the tractor sold for the substantial price of $2,800.
