The Aultman-Taylor Machinery Co. was well known in the late 19th century for its steam engines, threshing machines and other equipment. It could trace its roots back to the C. Aultman Co. which was founded in 1859 by Cornelius Aultman. It was not until 1910 or 1911 that Aultman-Taylor began to produce tractors though, and it entered the market with the legendary 30-60 model. Early models had a square radiator, but this was soon replaced by the more familiar tubular one. The range of tractors was expanded over the next few years, the smallest of which was the 15-30 of 1918 with a completely enclosed bonnet. Unfortunately the company experienced financial problems and in 1924 it was taken over by Advance-Rumely, who subsequently advertised Aultman-Taylor tractors alongside their own products until the remaining stock was exhausted.
