don't know my own strength!

So I got out the snap-on 1/2" breaker/ratchet and hauled on them. I got two of the three off. Bear in mind, I was not using a pipe on the handle- just pulling on the breaker bar with my hands and pressing against the inside of the rear wheel with my feet.

Then the last one broke off! A 5/8" bolt with a 3/4" head! Now, to be sure, I was able to exert my full strength on it, but this must have been a low quality bolt! Maybe they used a low grade of steel back then.

So now, I have a bolt broken off flush with the surface. Since I was unable to budge it when I could get a socket onto it, I seriously doubt that I can get it out with a screw extractor.

My current thinking is to weld on a stud in its place and use a nut to hold on the drawbar. Since the drawbar will always be mounted, this should not be a problem. I suppose I could try drilling it out and re-tapping. What fun... :(

Or, I reckon the drawbar will hold on ok with just 3 bolts...

On old iron, if a bolt or nut is the least bit stubborn, I break out the torch. Many times I've broken the first bolt, then applied a little heat to the remaining bolts and had them come right out.

I think the idea of welding a nut to the broken stud will work. Just add more heat if it doesn't come out immediately. Don't be shy with your torch; you'll probably need to get it red before it loosens up.
