Bullbuyer brought up a very good subject about tractors. And that is tractor fatalities. And that is something that can happen on any tractor. Large, small, new, old, 2wd, 4wd.
I remember when i was a kid years ago where a old farmer who had been farming all his life started up a little incline with his dics up in the air. Somehow the tractor flipped over backwards pinning him between the tractor and dics. It caught on fire and burned the man alive.
Another time not long ago close to here they found a tractor still running with the PTO engaged to a six foot brush hog. They found the operator ( a woman) a fleshy mess underneath the hog.
Then there was a man tring to stack round bales in a barn and had the round bale roll back down the loader onto the drivers seat with him on it. It broke both arms, neck, back etc...., Cattle farmer is all he has ever been. (not a hobby farmer either) Cattle is the way he makes his living. He was on a open station tractor.
These people who work for the state on mowing crews are always rolling a tractor over from time to time.
