Another Illinoisan checking in. I detassled with a kid who died this way one summer. He was like 17. Do NOT fuck around with corn silos. Have a classmate who's kid had his pantleg get caught in a tractor's PTO (I think - it may have been something connected to it)... absolutely tore his leg up and almost bled out (reconstructed and he's walking now). And knew another dude who had a tractor roll over on him on a slope. I personally, sank the end of a razor sharp derogueing hook into my thumb and narrowly avoided lopping it right off. It's dangerous fucking work and demands your respect and constant attention.
