Mr. Sam Couper of Winnipeg asks about an Ohio Tractor in the March-April 72 GEM. Here are a few notes I have found on this tractor but which all seems to be very confusing.

A March 1912 Gas Power magazine shows an ad by the Ohio Tractor Mfg. Company of Marion, Ohio. The tractor is called the Ohio Gasolene-Kerosene Tractor. It has famous patent friction drive built in the following sizes: 20, 30, 45, and 70 HP. It also has the combination tractor-roller, and our tractor hay baler on which we use our friction drive when baling hay or when running over the road. Leader steam engines and separators so favorably known for 25 years, are the goods we manufacture.

A reprint of a September 1912 Gas Review pictures an Ohio tractor in the August 66 E. & E. The owner, O. T. Nolan, Perth, North Dakota, states he has been running the Ohio tractor the last two years.

Floyd Clymers book on Steam Engines shows the Leader Steam Engine in 1915 by the Leader Mfg. Company, Des Moines, Iowa. While 'Power in the Past' by Chas. Wendel states the Leader Tractor Mfg. Company, Des Moines, Iowa, placed advertisements in 1919 in some trade papers stating 'We build the famous Leader Steam engine, separator, and steam road roller; the kerosene tractor, the kerosene road roller.' They further advertised themselves as successors to the Ohio Tractor Mfg. Company, Marion, Ohio.

A January 1919 Chilton Tractor Index lists the Leader Tractor Mfg. Company, Des Moines, Iowa, with the following Ohio tractors in 1912, 10-20 two-cylinder 7?' bore, 15-30 two-cylinder 8?' bore, 22-45 two-cylinder 9?' bore and 35-70 two-cylinder with 11' bore. Then also a 12-25 Rex built in 1918 is listed with a four-cylinder engine with 4?' bore.
