Samson Tractors & Lineup

Samson was an American agricultural machinery manufacturer that emerged in the early 20th century, initially gaining recognition for its innovative 'Sieve Grip' tractors. Founded in Stockton, California, the company quickly established itself as a pioneer in orchard tractor design, with its low-profile, three-wheeled models featuring distinctive open-tread steel wheels that were ideal for navigating between trees. In 1919, General Motors (GM) recognized the potential of the tractor market and acquired Samson, relocating its operations to Janesville, Wisconsin, where it merged with the Janesville Machine Company. Under GM's ownership, Samson introduced the more affordable 'Samson M' tractor, which achieved considerable commercial success due to its competitive pricing. However, the company's ambitious plans for a larger 'Model A' were sidelined as resources were diverted to the development of the Iron Horse cultivator, a product that ultimately proved to be poorly designed and unable to compete in the crowded agricultural machinery market. Facing mounting financial losses and fierce competition, GM made the strategic decision to discontinue the entire Samson line in 1922. The Janesville factory was subsequently repurposed for Chevrolet automobile assembly, marking the end of Samson's brief but impactful tenure in the tractor industry.
