Does anyone know how to locate English manuals for a Shibaura SD2243? I have found parts manuals in English, but no luck in finding operator or service manuals. The engine # is H843. Maybe that engine can be found in an American made tractor and cross referencing can be done to figure engine capacities, filter types, etc. Any help or leads would be greatly appreciated. By the way the tractor I bought runs like a champ.
