This original operators manual gives you information on operating the Model 63 Rotary mower 3 blade rear mounted for use on the 5020 and 5030 tractors (tractors are not covered), as well as basic maintenance guidelines. Lots of illustrations, and instructions to help familiarize you with the machine.  Manual cover has a piece missing, manual has smoke damage (may have soot stain on cover and page edges, but pages are legible) but is otherwise in good usable shape.
