After tilling the garden I tried to stop the PTO but tiller kept turning. Tried the PTO switch several times but no luck. Shut tractor off and switched lever to mid PTO, started back up, now the rear PTO stopped but the mid PTO is running with PTO switch off. With the switch on the tractor does shutdown if I get off the seat. Took panel apart and checked switch with meter and checks good.
I know you said you checked it but my bet would still be the switch.If you will start the tractor and cut the pto switch off if you can without hopping off unplug the pto switch and see if it cuts off. If so then it's probably the switch if not then there is possibly a short somewhere.
This test is assuming the switch is normally "open" when the pto is disengaged. More than likely this is the case but without the schematic then idk. If the switch is normally "closed" then it shouldn't change anything. I'll edit or post another reply depending on when if I can dig up the schematic for the thing.
I would check to see if there is power at the solenoid when the PTO switch is off. If there is then I would guess you have a relay stuck of some kind of short in the switch. If there is no power to the solenoid and it continues to run than I would guess that the solenoid is stuck open.
You will be iterated in section 27 part 52 below

(A) WHEN REPLACING FOR THE FIRST TIME, REFER TO DTAC SOLUTION 70105.
I unhooked the connector going to the solenoid and had 0VDC at connector with PTO off. Turned switch to on and had 14VDC. I took apart the solenoid and checked the spool, but nothing looked wrong with it. Maybe I will replace the solenoid and try that. Hope it's nothing more serious though!
Hemms that sounds right. I doubt the solenoid is bad. Lemme take another look there may be a relay somewhere stuck open my bet is relay or switch if the solenoid looks good. Check the relay noted in this diagram if you can find it My bet is the relay is bad if the switch is ok.

A relay can't be bad if there was voltage at the connector when turned on, no voltage when turned off. The electrical side of the system seems to be ok.
if he is checking the control side of the relay coming from the switch which is reading correct.
BUT
the load side of the relay could be stuck in the closed position (this could happen if the contacts weld together and do not release when de-energized).
check voltage on the load side of the relay to to verify it is opening when switch is off.
Good point. I'm bad about throwing things out there without a full schematic. Diesel does make a good point. You're probably OK electrically it's probably on the hydro side of it now which I can't help with as I don't know really anything about hydros.
The way I understood it was he checked for voltage at the PTO solenoid connector. :unknown: If that's true it rules out the entire electrical system as the problem.
Yes I checked at solenoid connector, and all checked good. I went to local Deere dealer and talked to service. We both came to same conclusion that solenoid is stuck. I ordered new solenoid won't get it until Monday afternoon. Will update when installed. Just hope that is the problem. $142.00 for solenoid
Well I replaced the solenoid with a new one but PTO still stays running. Ordered a technical manual, maybe that will help.
