Perhaps the neutral safety switch, like mine did, quit working. I got a new one; but never did figure out the way that the shims go in or are measured. It's still sitting on my bench for one of those "someday" things...........
As for starting it in gear, it's kinda like a car or any other machine. If you know it is gonna react a certain way..........You dont do that if it is gonna cause problems. When Princess, my grandaughter is around the RTV which she loves to drive, it is left with the brake on and she KNOWS not to fool around with it.........It's just like one of my power saws, radial arm, table saw, joiner, etc.........She loves to work with me in the shop and yes, she is only 6 but she can disc sand or stationary belt sand with the best of them. Does she start the machine by herself or EVER???????............Not if she wants Grandpa lovin on her and smilin. So yes, even today, children can be taught right from wrong and go along with the rules...........God bless.........Dennis
