HR_Mutt,
I am with you for the most part, at least with regards to tractors. I have worn the seat belt a few times on my
L3010. But that was when I was doing serious stump digging. I had the rears off the ground a few feet at times, a few times leaning over sideways, then the root would give loose and down we'd come. I couldn't stay put in the seat with out the belt. Strapped in I stayed more or less in the operators area. But all other times, never have, never will wear the belt. And I suppose, there is something to be said for the safety of the belt and ROPS when the tractor is canted sideways 5 deg+ and the rears are off the ground 2'.
I have studied ROPS removal. Lots of stuff to remove and they are heavy, I don't have any low trees, and my garage will be built with the ROPS in mind, so I guess they get to stay. I hated 'em on the golf course, I'd get slapped by trees in the face when they went around the exhaust stack, then in the back of the head when they flipped around the ROPS.
As far as air bags/seatbelts are concerned, I wear my belt with the airbag in an F150 religiously. I was involved in a bad accident with my previous F150. The other driver died, I walked away without a scratch. The air bag/seatbelt saved me from any injury at all. The belt arrested forward motion and kept me inline for the airbag, and the airbag stopped neck whiplash and steering wheel impact with head. I am very happy I had both. I had just traded in my old ranger a month before, and I never wore my seatbelt in it. New vehicle, new resolution, saved life.
