Here's a photo of my 1957 OC-46. It has the Hercules 4 cyl gasoline engine in it. I had to replace the left side bull gear and drive pinion and give it a tune-up, but other than that it works like a champ. I've already moved about 40 tons of fill with it to level out the floor of a polebarn I put up. I have several other photos if anyone is interested, but it is just your basic old OC-46.
