Magnetic Pto Shield
A magnetic pto shield invented by a retired Cornell University professor makes it easy to keep the pto shaft shielded.
Joseph Campbell, Cornell professor emeritus of ag engineering, came up with the idea two years ago. The shield consists of a length of plastic tubing with an inside diameter that's slightly larger than the out-side diameter of the pto shaft. A disc-shaped magnet fits into the end of the tube. It sticks to the end of the shaft when the tube is slipped over it. The magnet holds the tube in place on the rotating shaft, but it fits loosely enough on the shaft so that if a person leans against the shield or if clothing becomes caught on it, the tube stops turning while the shaft continues to spin inside of it.
"Barber pole" red-colored spirals on the shield make it highly visible when shaft is turning, adding an additional safety factor.
Campbell says Cornell University is looking for a manufacturer.
