The H.A. Wetmore Company produced tractors in Iowa from 1919 until the 1930s. Mr. Wetmore was involved in the automotive and tractor sales, distributing the Waterloo Boy brand. However, he lost his dealership when Deere acquired the Waterloo factory and started producing its own tractors. A challenging market environment led to price reductions in the early 1920s, ultimately causing Wetmore to stop production in the 1930s.
