I'm in the process of doing the same thing!. got the same problem.. I quickly learned that "time and patience" is needed on these oldies..

Wish I could find a set of fenders like your tractor has. Well, anything worth having is never going to be easy, hang in there.

I used to like PB blaster until I used Kroil. It's a lot better than PBblaster. It's expensive. I think the last can I bought was $14.00 a can, but it's great stuff.

It will be worth all the work in the end once you can actually use it again. Unless you want to sell it lol

On the G head I just swapped I sprayed the studs every day before I went to work. They ended up coming out easy, but not sure how much of that was just luck. I'm curious, what bushings are you talking about in the pedestal that will lead you to taking the whole pedestal off? If you raise the front end enough the shaft can come out. I took the whole pedestal off of mine one time but it wasn't really necessary.
