ROPS can be dangerous too. John Dee in the UP of Michigan was involved and it turned fatal during an accident on his ZTR with the ROPS up. He hit a tree and flipped it. Damaged his internal organs and he died at the hospital due to the injuries. Stuff can happen in an instant. We demo'd a ZTR a few years ago and it had the ROPS up. Was driving it near a tree and caught the branches somewhat with it. It did have a pop up incident and that was enough for me to determine you gotta be careful with the safety equipment too.
