That is downright scary and dangerous! If the PTO lever/button/whatever is disengaged, the PTO shouldn't be engaged. Others with more knowledge can chime in but I think I'd be having a mechanic looking at it ASAP.Once I got the chipper unclogged and started the tractor back up, the PTO shaft started turning even when I had the PTO clutch disengaged. It was that way for some time (~10 minutes or so).
