As long as I can still manipulate PTO connection - the shield will remain on. I DO have an advantage. The metal PTO stub shield on my tractor will hinge up and give extra room.
Mine hinges as well so it's not in the way most times. I don't care what anyone else does with the shield anyway, I KNOW what I do I AM the captain of this ship, no one else is. Put another way, you bought it and paid for it or are paying for it so what you do is 100% your affair.
Far as getting injured from a spinning pto shaft, happens all the time. You get a loose shirt sleeve or your hair caught in the spinning shaft, you'll wish you didn't, that is if you survive it. Loosing a digit isn't squat compared to playing rubba-dubba with a spinning PTO shaft. The ending to that is usually a wooden box in the ground and I don't mean a flower box either.
Why most PTO's have interlocks on them or in my case an audible warning when you leave the seat with the PTO on. In my case there is no interlock because mine are ag tractors and are built to operate the PTO without being in the operators seat.
Have fun, be safe and remember, you are 100% responsible for your own safety. That tractor is just a machine and has no feelings. It will injure or kill you in a second and will feel no remorse.
Why I never post I love my tractors. I don't, They are just a machine to to work more efficiently with. Nothing more.
