Point well taken and agreed. This is the only one without shields. However, regardless of shield or not, no one is allowed off the tractor seat when its running and has a PTO implement hooked up. If you need a water break you shut off the tractor first.not that the driveshaft in the picture is safe, far from it with no shielding whatsoever. That is an entanglement accident waiting to happen. Lots of people do that because shielding is a PITA until someone gets hurt or killed. No, non enclosed pto shafts on this farm
