Back in those days a new tractor was shipped with a new operators manual and a parts book. That is why the crawler manuals have more maintaince information in them. To my know there never was ashop manual for an HG, OC 3 or the OC-4 with the four cylinder Hercules. They are a basic simple little engine. You can all kinds of advice at this forum. So if you have questions ask away.
