Ohio Mfg. Co.

Known either as the “Morton Traction Truck” or the “Ohio Patented Traction Truck”, this device marked a new era in tractor design. Farmers could now mount their own stationary engines on Morton trucks. Dozens of engine builders saw in the Morton truck the chance to burst into the tractor business. International Harvester Company entered the tractor business by this route, and numerous other companies such as Foos, Callahan, Stover, and Rockford mounted their engines on a Morton gear. And just like that, they were in the tractor business. Several, such as International Harvester, grew into industry leaders, while others used the idea for a quick buck, and quit as soon as other designs created some competition.

U.S. Patent No. 725,760 was granted to S.S. Morton of York, Pennsylvania on April 21, 1903. Morton’s patent concerned a traction truck that could use virtually any gas engine for power. Upper Sandusky, Ohio was the site chosen for the Ohio manufacturing Company, a firm that was organized to build the Morton Traction Truck. Ohio Manufacturing Company offered their Morton truck as late as 1913. Conventional tractors appeared about 1916, followed by the Whitney 9-18 model in 1918. about 1920, Ohio Manufacturing Company was renamed the Whitney Tractor Company, but Whitney disappeared by 1923.
