Look's like it's unanimous that not being able to run pto while tractor is in reverse is a stupid excuse for safty. Also look's like ROPS get's thumbs up. IMO ROPS probably saves more injuries by preventing operator being hit by low limbs than actual roll overs. I thank each of you for your opinions because I was begining to think I under appreciate some safty features. Being born on a farm and operating a tractor unsupervised by age 10,I'd like to share what i saw and heard about accidents. Pto driven rotory cutters (aka bush hogs) tied with corn hearvesters as most dangerous for resulting in serious injury and death. Thank goodness those "corn pickers" was replaced long ago by more effecient and safer hearvesters. The problem was they often jammed up with stalks and cobs and was near impossible to unjamb without starting and stopping machine while pulling on debris. Needless to say a fair number of people got caught up in them. Rotory cutters have been improved but remain the deadlyest implement in common use to day. The biggest improvement was actually tractors coming out with Live PTO. Hard to believe but until early 60s you couldn't stop most tractors until cutter stopped turning which took about 10 to 30 feet depending on gear and amount of grass at the moment. i hear you when you say pto covers can be a real pita but think twice before removing it. More than a few bodies or what was left have been discovered after operator got near shaft and it grabbed their clothing. A simple to build and install shield behind operator will reduce your odds of injury more than all the factory installed combined. All right-of-way mowing tractors without cabs have them. Eventhough you know there wasn't anything in your field when you mowed several times before, illeagal disposal of trash is always a possability. And you can expect to hit something every time you mow public road in front of your place. A piece of expanded metal mounted to ROPS could save you one day.
