Thank you for the great comments! Tires are oversize. I traded an old broken small lathe to a guy for a dead fencerow tractor that had been seized for years. It had model B rims and tires on it then. I found and old AC Gleaner E combine and it donated a few things for the motor and the tires and rims. Cost was free. I brought it back from the dead and replaced what I could find with the help of Ebay, and rebuilt the old girl with more modern components for both function and fun. It has 12 volt electronic ignition assisted with MSD ignition and blaster coil, no points, and it will start darn near 1/2 a turn in -10 degree weather without the choke. Carb has been reworked to flow a touch more, it has a dry air intake, chrome straight pipe (yes it is loud!! /forums/images/graemlins/grin.gif) Gleaner E cam and gov. springs (snappier) it has WD45 diesel rear end parts, and a d-17 factory snap coupler 3 point conversion. It also has 12 volt charging/battery, as well as 170 series high altitude pistons/sleeves. Compression ration came out to just over 9-1, so it had to have a higher octane fuel, but it wound up making 73 HP at the PTO. I built it to be something classic looking, but interesting. It could work all day actually using it as a tractor, or pull a float with it in a parade and look cool. I never got a chance to try it pulling, but I bet it would have never been allowed into the antique class.
