When Emerson-Brantingham took over Gas Traction Company, they got the Big 4, “30”. Following much of the original Big 4 design, the company brought out the Model “20” in December 1913. It was also known as the Model D. Proving the trend to smaller machines, the Model D stayed in their line through 1920, several years longer than its bigger brothers. In late 1913, E-B took one stab at the giant tractor trade with its Big 4 “45”. Most of the large tractor builders tried to build the “biggest” tractor, but they were too clumsy to be of much value, except on the biggest jobs. Within a couple of years, the “45” disappeared. The E-B (Reeves) 40-65 tractor used several different radiators. The Reeves Company developed this tractor but had little chance to market it before the E-B takeover. E-B built this model in 1920. The first original E-B tractor design was the 1916 Model L, which was built in 1917. The Model Q 12-20 tractor was presented by E-B in 1917, and with a few changes, it remained in the lineup until J.I. Case took over in 1928. In an effort to grab some of the small tractor markets, E-B began offering the 9-16 model in 1917 until 1920 when it was discontinued. They announced the 12-20, Model AA tractor in July 1918, and it remained in production until operations ceased in 1928. A 20-35 tractor appeared in 1919. It was an improved version of the Big 4 “20” that came out in 1913. and then disappeared after 1920. In 1923, the E-B No. 101 cultivator appeared and remained in production until 1928. in 1921, the 16-35 was announced and was built until the end of operations.
