So what valves misbehaving can lead to the PTO being on all the time? If the PTO is staying on (and the MCV plate gasket is known to be good), what must be open and allowing pressure to get to the PTO port? I can disconnect the linkage completely and the PTO stays engaged. I have removed the pto valve from the MCV, and I did not notice any problems. I'm not saying there isn't a problem, but the valve moved freely. I am contemplating hooking a gauge up to see exactly what kind of pressure I have while it is "off" and still turning. As I said before, you can hear something different going on when the PTO is officially engaged--this would lead me to believe that the pto valve is opening more (and it is not a straight and full flow leak), but can a leak on that valve in the closed position cause this? Are there any remedies for a valve that leaks--I only see two o-rings in the breakdown, and I doubt either are in "keep the pto from turning" places.
BTW, I'd assume a stuck flow divider valve would keep something from working--not keep something from turning off.

While this may have been the bread and butter of the belt work in the past (since this is what made the money on many farms), the smaller tasks may have been and still can be its real claim to fame. The thresher would bring in the harvest (and income) once a y
