Very few folks would have a quick enough reaction time to jump off a tractor roll over. Years ago, when I had a lot more stupid, I tried to pull down a huge pile of pine bark with the front end loader of my tractor. The tractor was small enough that I had to drive up onto the pile and it collapsed and the tractor went sideways and started to roll over. I ended up with my back on the concrete slab and my feet in the air holding the tractor up at a precarious balance. After about 20 seconds my strength gave out and I thought I was a dead meat. Lucky for me my younger brother saw what had happened, ran up and shouted, "I'm going count to three, and on three I'm going to yank you by the arm pits as fast as I can. We both tumbled back on the concrete and the tractor landed on its side right next to us. Lots of scrapes and bruises but I am alive to tell the story. The tractor was still running on its side when we turned it off and oil was spilling out the air intake. We got another tractor and chain, righted the tractor, took out the saturated air filter and started the engine up. It smoked tremendously for about 3 minutes and we ended up using it for another 8 years before trading it in. Lucky for me and lucky for the tractor. I have been much, much more cautious since that incident......
