Yes I have parts diagram as well as workshop manual. Some suggestions from other members have been pretty simple, "get a bigger hammer" which is spot on with where I'm at. I had another comment about the possibility of there being some "mushrooming" from the needle bearing failure. As for the workshop manual, it explains it as coming off without a hitch? Regardless, it have to come off or I have one big concrete weight.....Do you have the parts diagram in PDF for your tractor?
