What you don't tell new people (because of some inherent danger) is you can get off and when you are hooking up your 3pt implement if you didn't quite get far enough back that the telescoping lower links can reach the implement pins you can use your hand to press the reverse pedal a bit to move the tractor backwards. You don't mention that because of the inherent possibility the "newby" will push on the wrong pedal and run over his dang foot and maybe even smashing himself to the ground if he panics and keeps mashing on the pedal. But like I said you would not mention such "features" to a newby.

You would also not mention that if you were behind the tractor and operated the remote rear 3p control and happened to lower it with your foot under the implement and dropped said implement on your foot. Well you get the picture. I have not actually done that, but it is a possibility. Any time you work with several thousand pounds of machinery and hydraulics, something bad could happen if you are stupid.
