This is one deep place. The boss got an antique diesel walker MDDSD which I got running by the seat of my pants(fingers crossed). This thing only has a serial number so our dealer can't identify it to get manuals. Can anyone guide me to manuals or has anyone had one of these? It has a kubota D600 engine, no parking brake and pre micro-v belts. I sure would like to find out the max rpm, and belt numbers. Would a newer model manual have the same part numbers?
