We certainly live in a society where there needs to be labels with warning signs and guards to protect us from ourselves and to cover the butts, legally speaking, of the manufactures. Gone are the days where people simply know not to touch something because its sharp, spinning, hot, etc. Common sense doesn't seem to be so common anymore. Fortunately, I was raised around older machinery where there were no guards and no labels. Only heavy steel, half painted and mostly rusted. Yet, I never stuck my fingers into a chain sprocket while it was spinning. I was taught that sticking my head into the baler would cause death. Or that attempting to hook up a PTO shaft while the PTO was spinning would result in a catastrophe. As a young boy, I was stupid. I did a lot of stupid things, such as running the tractor off the road because I wasnt paying attention, or shooting the cat with a BB gun. But I never got hurt on farm equipment. Why? Because my grandfather, my mentor, taught me that equipment, in of itself, is dangerous and should be respected but not feared. He taught me that when you hook (or unhook) up a PTO shaft, on anything, that the tractor needs to be OFF. As in the engine is OFF, not running. The pistons are not moving. The key is in the OFF position. ALWAYS. That was pounded into me. There is no way that PTO shaft could spin fast enough to hurt me if the engine was turned off. To this day, whenever I hook up anything to the PTO shaft, the engine is off. My son, whom will learn how to operate the tractor, will always know to turn off the engine whenever he needs to hook or unhook that shaft. He will have the same lessons I learned when I was his age. Because that builds common sense.
If a safety guard is in my way, makes my already hard life that much more difficult, it gets removed.
