Oh, I don't know. I've been welding for 31 years now, and I have seen it
work many times to get a bolt out when nothing else will. In some cases, it
melts the seizant used when the bolt was installed.
Because maybe the head is the part seized onto the shaft. Once the nut
portion is ground off, heating, twisting, and a little punching should get
the blade off, and allow one to get to the threads, which is the part
holding it all in there. And the shaft of the bolt, which is an ideal place
to apply torque.
Or, as you suggest, one could just take a sledge hammer to it............
It seems that way in theory, but it works in practice. I had an AC
bracket on my '67 Pontiac Catalina with the 400 c.i. V-8 and since it
was a convertible and the AC was broken, and I couldn't remove the
sparkplug from the #1 cylinder, I decided to take the AC compressor
bracket out. I had cheap 3/8" socket wrenches and with my hands and
maybe a cheater bar actually super-torqued the 6" extension so that
the top was turning and the bottom wasn't moving at all.
Got another extension, ran the engine for 10 or 15 minutes and got the
bolt off with upper moderate to great effort.
Used a propane torch to heat up my motorcycle crankcase, and got out
all the bolts that I couldn't otherwise. Had stripped the head of the
first one. (They hadn't been turned since 1967, iirc.) I didn't heat
the bolt heads, but went around to the side of the case, sometimes
several inches below the head, and heated that.
I agree with you here.
Maybe a lighter hammer. You just want to knock the guy out, not break

And whack the Vise Grip with a hammer. I've never been able to damage
a Vise Grip and they're not that expensive anyhow. And the shock of
the hammer is like an impact wrench but cheaper.
Harbor Freight has an electric plug in impact wrench for about
$80. Goes on sale often for $40. That, and a ten dollar black
impact socket set. Very often the rattling of an impact wrench
will free up rusted on bolts. I've had good results with removing
rusted on wheel lugs, etc. So your mower bolt may respond to
Heat it up with a torch will often assist. If you don't have
acetylene, the yellow tank Mapp torch from Home Depot does a very
