It does happen, those bump bars on the back are there for a reason and it better to have to reset them then the alternative.
A fellow here son came to get him one evening for dinner while he was chopping silage, who knows why kids do what they do but he waited for his dad on the standing corn side. Didn't see him just heard a scream, they buried the whole load of silage. I get careless sometimes like everybody but one thought of that story snaps me out of it in a hurry. Don't know how you go on from that.
Be safe out there everybody!
