Hey, now. I have a friend, whose brother knows this guy, who is his second cousin's sister-in-law. Anyway, this guy's boss's wife had an uncle who died in a garage because he forgot to open the door. It wasn't from CO, though. He drove the tractor through the door.
Or maybe it was an rural legend.
Guys ya got it all wrong what ya do is build your garage floor so it slopes at a 45deg. angle to the outside. Then ya fold down the ROPS, back the tractor up to edge of the garage door, pull forward 10ft, put it in reverse, start the turbo boost, pop the clutch and just as you reach the edge of the garage kill the engine, push it the clutch and then hit the brake just before you hit the back wall. That way your not violating commandment #4 since you can now release the brake and coast out of the garage. It's easy.
