I have a photo of a tractor that I would like to identify. It is faded red in color. The engine appears to be a single-cylinder Kohler or Briggs & Stratton. On front of the engine is a chain-drive pulley possibly connected to a starter which is mounted above the engine. Also in front of the engine and behind the grill is a huge battery....probably a 6 volt. There is no radiator as the engine is obviously air-cooled. To the rear of the engine is a set of huge belt pulleys possibly connecting to the huge differential under the drivers seat somehow. In front and to the right of the steel drivers seat is what appears to be an open tool box with a metal ID tag attached. (illegible stampings) The rear tires appear to be of the regular "Farm Tractor" size....as opposed to garden tractor size. Although not completely visible, I believe the front-end has a single tire. Can someone help me identify this strange tractor Please?
