And stuck bolts don't care about theoretical physics. Have you ever
had to remove any REALLY stuck bolts??

I have a stuck bolt right now holding a lawnmower blade on that belongs
to my neighbor lady, removed two of the blades but the third one will
not budge. I have used an impact wrench but someone had rounded the bolt
before and even tapping a smaller fraction size on it will not grab good
enough. Tried vice grips and pipe wrench--what next, maybe heat. I am
afraid it will break and then the mower will be toast, it is an old John
Deere her husband had before passing away. Any ideas?

3 blades? Do they all turn in the same direction? If any spin in the
opposite direction the bolt will also for loosening or tightening.''Look
at how the belts wind around the pulleys.
