Seen all kinds of stuff, and there aren't always warning labels. RTV's don't' have a label under the seat regarding the engine-driven fan; and I've lost the end of my index finger because of it, not knowing that was a fan in there at the time. I certainly do now. Been down for about 8 weeks and just now able to kinda halfway hunt & peck enough to type.
Guy a few years ago when I worked for a JD dealer was hooking up a bush hog and the top link pin wasn't lined up quite right. So he sticks his finger in there and as he did, the hog was sitting on a rock that was on the shop floor, it shifted and lopped the end of that finger off as if it were a finger cutter. No mercy with equipment, so yes, you have to be on your toes.
I've seen guys working under loaders and someone walk by and lean up against the joystick, then loader drops. Nobody getting hurt because of it but the guy working under it sure moved quick.
Seen where a guy bypassed a seat switch for a customer, customer lost control and got bush hogged. Dunno if he lived or died. I don't want to be in any of those situations--and actually this instance is exactly why I refuse to comment on a switch bypassing, even for testing purposes.
And...many moons ago, I was about 10 I think. Lived out in the Midwest. My dad had friends who owned a large farm, and every summer he'd take us out to the farm for a few days, to get out of the big city life. We kids loved it. Anyway, the farmer had a daughter the same age as I was (well a few months younger). They had 3 wheelers, those dangerous things.....anyway, we were out riding and I got out front. Rode about 15 minutes and realized that she was nowhere behind me, nowhere to be seen. So I turned around thinking she'd taken a different way back to the house. Never found her. So I went back the trail I was riding and came up on the old tractor we'd passed, tractor hadn't been used in a good while but it was just sitting there. Passed it up, never seen her anywhere, so I turned around and headed back expecting to meet her at the house. On the way, I come up on the old tractor and seen the 3 wheeler a short distance away with nobody on it, laying on it's side. Got closer to the tractor and I found her. It had a hay fork on it, and she apparently lost control, ran head first into the fork. The fork was still sticking out of the back of her head. She was motionless, cold, and unresponsive. Being young, I panicked and had no clue what to do. Knew to not pull her off. Hopped back on 3 wheeler and got to the house and told my dad and the farmer what had happened, they called 9-1-1. Believe it or not, she is alive to this day, we are still friends, and amazingly enough, she is fine other than a scar on the back of her head. Cosmetic surgeries fixed the scar under her left cheek and she has some fake teeth. It was nothing short of miraculous that she lived through it. And interestingly enough she helped lead me to salvation a number of years ago, so in a sense, the circle is unbroken.
Again, I can't stress enough how dangerous farm equipment can be, equipment in general. Really anything can be dangerous but especially machinery. We all know it but some of us chose not to respect the power of what we've built, which is stupidity. And stupidity in the wild is what helps control population growth, and stupidity is a big reason we have so many laws...to protect idiots from themselves in most cases.
