Gibson

USA • 8 Models

Gibson was a pioneering American tractor manufacturer with a relatively brief but notable history in the agricultural machinery industry. The company was founded by Wilbur Gibson in Longmont, Colorado, in the early 20th century. Gibson's manufacturing facility in Longmont became the birthplace of several innovative tractor models that gained recognition for their durability and design. The company's early success was marked by its commitment to producing reliable farm equipment that met the needs of American farmers. However, Gibson's independent operation was short-lived, as the company was sold to Helene Curtis Industries in 1952. This acquisition marked a significant turning point for the brand. Following the sale, Western American Industries took over the Gibson factory and resumed tractor production from 1953 to 1958. Despite these efforts, the Gibson brand ultimately ceased operations during this period, and the factory closed permanently. The Gibson legacy is remembered for its contribution to the development of early American tractors and its role in the agricultural machinery landscape of the mid-20th century.
