MANY things can fail in the PTO unit, the simplest of which is a little pin that holds the upper and lower parts of the control valve together. If it failed completely, all at once, the pin is the prime suspect. If the little pin breaks there will be no PTO apply pressure. It is simple to disconnect the control linkage, and remove the large plugs at the top and bottom of the valve, and see if it has fallen apart. If that is the problem, the pin needs to be replaced, the parts reassembled, and then the PTO operating pressure needs to be checked at a test port. If you decide to tear into it, it's best to at least have an I&T manual at hand, to see what's involved in repairing it, and checking/setting the pressure. If the little pin has not broken, the problems could range from a failed pump, to a blown seal, to a torn up clutch pack.
