I see the 2 answers the one about using heat and the one about leaving the dw-40 on for 24 hours. I've done both. Neither worked. I tried boiling water, soda pop, vinegar, torque extender, everything I can think of. It will not budge. I saw a video where the person actually had to break the agitator by cutting it with a chainsaw, then extracting the remainder of the bolt with some special power tool and replacing the whole agitator. Is that what I'm going to have to resort too? I hope not.
