Impact Wrench II

Sounds like your next purchase will be:
1. Breaker bar
2. Cheater pipe
3. Band aids
4. Drill and sharp bits to drill out broken bolts

But just think of how easy it will be for the next guy in the future after you replace all those rustd tight fasteners with new ones?

That's not to say a bigger hose, or more pressure aren't goint to be REQUIRED to make that thing work, but there are a lot of times the gun aint gonna get it.

In those cases we might just grab a bigger tool, like a long wrench, or the 3/4" drive breaker bar, or biggbutt ratchet and put a 10' pipe over the end that to stand on, thus increasing our available torque (by a lot).

Most of the time when working on old rusty tractors and the like, the next tool I'll grab after the gun is usually going to be the Oxy/acetylene torch. Turn them babies red a couple times, squirt some smoke juice on it and away it comes.

I don't have time to jack around with incidentals, I need to do the job and move on to the next.

After mumbling a few incantations and checking this that and the other, discovered that I'd inadvertently bumped the forward/reverse button into "neutral". (In the middle: Not all the way in the Forward position, not all the way in the Reverse position). Pretty easy to do when yer flat on yer (old, decrepit, overweight) back under a truck and workin' over year head.
