Tractor Info


Probably one of the best tractors of its time was the Aultman-Taylor 30-60, first offered in late 1910 or early 1911. From this time on to the sale of the company, the 30-60 remained at the top of the Aultman-Taylor line. A full canopy was standard equipment. Width was 107 inches across the 90 inch high drive wheels. Height was nearly 11 1/2 feet, and length was over 18 feet. It weighed 24,450 pounds. The early models used a square radiator with induced draft being provided by the engine exhaust. The 30-60 was Aultman-Taylors first and most successful internal combustion engine earning the nicknames “Old Trusty” and “King of Road Builders” for its role in road infrastructure across the United States.

Although some advertising as late as 1914 shows the 30-60 with the square radiator, many historians have it that the change to the tubular style came somewhat sooner than that. The induced draft setup was abandoned in favor of dual fans which pulled air through 196 two-inch tubes in the 120 gallon radiator. Although it was company rated to have an 8,000 pound drawbar pull, Nebraska Test No. 30 showed it to have an amazing pulling power of 9,160 pounds. The power plant was of four cylinders, cast in pairs, with a 7 inch bore and 9 inch stroke, operating at 500 RPM. Two clutches were used — the one in the flywheel was for forward ground travel, and one in the band wheel for belt work. An idler could be pulled into gear on the band wheel clutch for reverse travel.
