I wire brished it out today, it went on snugly. Couldn't find the right locking pin, no one had one in stock, just happened I had a push lawnmower axel in my junk bin it fit right in put a nut on it and went to work. When it was time to unhook the shaft slid off smoothly. I put the pin and the end of the
pto shaft in a plastic bag, well greased of course. Should hook right up next time. Thanks for all the useful information. I was so happy I even washed my tractor before I put it away.
