Ok so I finally figured out why my PTO lever was functioning backwards and beginning to slip way too easy. After checking it all out and referencing a manual, (thanks Tom Arnold for giving me the link)I noticed that the previous owner had assembled it COMPLETELY backwards. Also most of the parts are worn badly. Disappointed. Oh well I guess I gotta remember that I got this unit for next to free and have managed to use the tractor quite a bit for a number of years already. Anyway, bottom line is I need most of the parts or a complete replacement clutch. Does anyone know where I could source the part(s) for less? Found one on ebay for about 600 bucks. Ouch. The tractor is worth it, however I currently can not afford that kind of repair bill. Then it would have to wait till at least next spring. Is it likely one would find a good used one? Also do they fit from different case/ingersoll models?
