Tractor Info


This unusual tractor was built by Bull Dog in 1920. A powerful machine, it was equipped with a Waukesha four-cylinder motor of 5 x 6 1/4 inch bore and stroke. The four drive wheels were forty-two inches in diameter with a fourteen-inch face. Lugs were available for increased traction. Rated at 45 horsepower, this tractor sold for $4,250 in 1920, apparently the only year it was built.
