I can't really tell, Bob, but it looks a good deal like the "Mini Tractor 5 and 8 hp" model to me, though that one had B&S engines. It also looks as if you may have some potentially expensive parts missing (almost the whole crankshaft clutch, for example). Interesting machine, though, I hope you get it going. Some pictures of the engine part of the drive train would be useful for our Greenfield archives - we've only seen the wheel-drive mechanism up to now.
