Yah, the guy on the tractor was lucky, he tried to jump off and I yelled at him to sit still and not touch anything, as those lines most always reset after the initial trip, before they fully open, and it surely did, exploding a second time shortly after the first. If it would have reset while he was trying to jump off grabbing the steel, he would have been toast. Dig alert is very useful, that line was not where it was supposed to be.
