Been there, done that. Just read an old thread here that disturbed me.
As the son of the Product Safety Manager at Deere, I was regular filled with horror stories about injuries suffered by tractor users.
Then I rolled my 670.
The right front wheel went up a berm as the left front one dropped into a shallow hole. The tractor went over counter clockwise in slow motion. My poor wife witnessed it from the top of the hill, rolling away from her, and me swearing up a storm.
As it went over, I reached for the seatbelt buckle. Then I heard my dad in my head.So, realizing that if I did it wrong and got hurt, I'd NEVER hear the end of it, I gripped the steering wheel with one hand, and the uphill fender handle with the other. (That's what it's there for. If you grab the fender lip, your hand can get crushed.)"Son, if you ever roll your tractor, hang on and ride it over. The seat is the safest place to be, and you had better always have your seatbelt on.
You can't out run the tractor downhill. It will squash you. If you try to get off on the uphill side, that big rear tire is still turning and will wrap you up."
The tractor laid over on its left side. When it settled, I released the seatbelt and got off.
First, I called a towing company to come right the tractor. Then I called Dad.
Not a scratch on me or the 670. After the tow truck righted it and dragged it up the hill, it fired right up. I was cautious about starting it, lest oil or fuel had leaked into a cylinder and hydraulic-locked it.
There's a term for the wives of tractor drivers that don't use their roll bars and seatbelts.
