I have an old abused rotary cutter (brush hog).
I have no idea what brand it is. I has been painted all red.
I am wanting to remove the driveshaft from it and use it on something else.
Normally I would expect a shear pin holding onto the gear box.
But this has something like a set screw. But it is more like a 1/4 inch bolt with a square head on it. Or rather it had a square head on it. I took a wrench and tried to remove it and the head broke off. All that was left was the threaded shank sticking up.
Ok, so I found a nut that would screw onto what was left of the bolt.
Screwed it down even with the top of the bolt and welded it in place.
Ok, so how should I proceed from here.
I'm afraid if I just try to turn the nut, the bolt will snap off flush with the yoke.
I was thinking of heating the yoke to expand it, then remove the "bolt"
Isn't there a trick of some kind where you heat it and spray it with WD-40
and it wicks the oil down into the threads to help remove it.
Seems like I remember reading something about that here somewhere.
My RC hardly gets any use. And I need the drive shaft for something else.
When I put it back on the RC I will use a shear pin.
So how do I get this "bolt" out without doing any more damage.
Thanks.
