I'm trying to remove a tire from a lawn tractor and the bolt is stuck. I've tried all kinds of penetrating oils and an impact driver with no luck. A lot of websites recommend heating the bolt. What kind of heat source should I use?
Addition: Thanks for the tips. The problem with a breaker bar in this case is that, due to the shape of the tire rim, I need to use an extension to get a socket wrench on the bolt and the bolt head is thin so everything falls off easily.
