You ought to play the lotto. Getting hit twice and talking about it. You are a lucky dude.That is what it looked like to me. Going right at him which would be right toward the camera. The tractor was on a vector line that was intersecting the tornado's line of travel. It looks like the tractor got to the spot first and if he kept going he would barely miss the tornado.
That tractor reminds me how I got hit by lightning twice trying to beat the storm by finishing a field. It was two back to back years and the same tractor, same field.
