My JD 4240 Has hydrostatic PTO and PTO turns all the time. If you decide to Bush Hog you must Hook Up PTO before cranking the Tractor and PTO does not stop turning until you switch tractor off.

Depending on which transmission(powershift or quad range) different things can go wrong. pto brake could be worn out or clutch could be damaged and dragging. Also linkage can be out of adjustment or worn out or broken. Does the pto run under load even when lever is in disengaged position?

Yes it is a powershift and it does run under load. Works great but is very very unsafe.
What is the history on this? Has it ever worked properly since you owned it? If so, did it gradually get to this point or was it a gradual thing? If it runs under load, then chances are that the clutch is fried and that in turn usually wears out the brake. The clutch is accessed at split between engine and clutch housing. The brake is between clutch housing and transmission housing. Before splitting, I would check clutch and brake pressures to be sure the valve is working properly.

One day after bush hogging, it would not disengage any more. The lever on the left side of steering column will move as always but it does not disengage pto.
