1927 Wallis 20-30 Tractor

 This tractor (serial #54238) was made by the J. I. Case Plow Works Company in Racine, Wisconsin. The J. I. Case Plow Works Company – not to be confused with the J. I. Case Threshing Machine Company – was created in 1919. Before that time, the Wallis tractor was produced in the J. I. Case Plow Works for the Wallis Tractor Company, a firm created by Henry M. Wallis, Sr., the son-in-law of J. I. Case and president of the plow works. In 1928, the company was purchased by Massey-Harris, the builder of another tractor here in Stuhr Museum's exhibit.
 This particular Wallis tractor has a patent date, Nov. 28, 1916, which corresponds to patent 1205982. This patent was for a tractor engine developed by Clarence M. Eason and Robert O. Henderson, assignors to Wallis Tractor Company of Racine, which you can view as a pdf here.
