Description: Wallis Tractor was founded by Henry Wallis, the son-in-law of Jerome Case. Henry Wallis was also the president of the Case Plow Works, which had been founded by J.I. Case. Early work on the Wallis tractor dates back to 1902 and some assembly in Cleveland, Ohio, but the company was formally organized in Racine, Wisconsin in 1912. In 1919 Wallis Tractor Co. and J.I. Case Plow Works were merged to form J.I. Case Plow Works Co. The Cub Jr., Models K, OK and Certified tractors were all lightweight Wallis models.
