I was driving-well,steering anyway- a Farmall C tractor before I even started school. All I had to do was drive between 2 rows of hay bales while Dad and my grandfather loaded the wagon,then Dad would jump on at the end of the field and get me pointed back up between the next 2 rows. So being around tractors and farm equipment all my life,I knew how dangerous it could be.But my last year of high school I only had 2 classes in the morning,then i'd go home and help daddy on the farm. I was picking corn one day,had a mounted cornpicker on a 5000 Ford tractor. There was a set of rollers that went up behind you and a fan-the rollers shucked the corn, most of it that is, and the fan would blow the shucks off to the side. A corn picker is very dangerous, there are many things that can grab you, and I knew to always turn it off before you do anything. So I knew better than to reach behind me and clear the shucks away that had packed up in the chute with it running but I did it anyway. Something caught the end of the sleeve of my jacket-and pulled the whole sleeve off. If it had been a better jacket that the sleeve didn't come off of it would have been disastrous. It scared the hell out of me. I took what was left of the jacket way down in the woods and threw it away and never told anyone.
