Big 4 Farm Tractors
This early design was later improved and became the basis for the famous "Big 4" tractor line, so named because of their massive 4-cylinder engines and overall size.
Transit Threshers
By 1906, Patrick Lyons had become interested in Hartsough's tractor design, and an agreement was reached to build the tractor at a factory in Minneapolis. Originally, the new company was named the Transit Thresher Company, which reflected the notion of Lyons to eliminate bundle wagons by moving the tractor and threshing machine around the field to the grain shocks. The "transit thresher" concept proved to be unpopular, and therefore the company was reorganized in 1908 as the Gas Traction Company, to manufacture just tractors.The Gas Traction Co. remained an independent entity until 1912, when it was purchased by the Emerson-Brantingham Implement Company of Rockford, Illinois. Emerson-Brantingham continued to build the venerable "Big 4" line of tractors, eventually expanding it to include several power sizes.
