I've read (after already attempting this) that heat may not be the best thing to use near the spindle. If I break the spindle, I'd be out roughly $100 to buy a new one on ebay or something. I am still thinking about how I should do this. I was thinking that heat causes expansion, so if I can get it good and cold, that should cause contraction, and perhaps that would give me a chance? Is supposedly a freezing lubricating compound (something like ).

Purchased some 'freezing' compound that is said to free 'rusted' bolts, but I fear that rust is not the problem that I am dealing with. I have purchased a new 60' section of steel pipe to be used as my new cheater pipe, but have yet to attempt in hopes that I can do something that hopefully won't destroy the spindle. I have also tried a breaker bar plus cheater pipe (but sadly only had a piece of copper pipe which seems to flex too much). I've tried heat and penetrating oil, and I have a new impact wrench ( ) that seems to have a bit more oomph (~700 compared to 220 ft lbs) than my Craftsman C3 19.2v cordless (which is generally sufficient for most things). The third blade simply will not come off as the bolt is stuck.

I sharpened two blade with no issue at all. This time around, I need to resharpen them because I, like an idiot, ran over something fairly solid that got picked up and whacked the blades good. I have a 52' Exmark Turf Tracer that has been a very good mower for me, and I had sharpened the blades earlier this season with no problem. Well guys, looking for comments on how to proceed.
