I have a John Deere rider with the electronic PTO.  PTO stopped working so I replaced the switch. Still not working. Any help would be appreciated. Its about 6 yrs. old and has a 23 HP Kohler engine.

Check the wire with a 12 volt test light to see if you're getting power. Also, check any fuses. Could be as simple as a blown fuse or a loose wire.

Check all the wires you can.Use common sence.
If that don't work take it somewhere-it's probobly something simple but you got to know all about mowers to figure it out.

Check the safety shutoff  on the seat assembly to make sure its not corroded/wire broken.

What model is it?

On almost all JD models there are relays controlling this. The starter relay, and PTO relay are invilved here. The shitty part is the relays are located under the battery in most cases, and battery acid, and fumes destroy them.

Bypass all the switches and wiring to the pto by running a hot wire and a ground straight from the battery to the pto if it does not work you need a new pto. If it does work then you have a bad wiring problem.

i have a john deere l120 rider ,  had the same problem 2 times  ., first time it was the seat switch , the second time it was the pto itsself , was expensive 320 for all the parts and i installed it myself .

like others said check all the wiring and switches first , than put power to the pto and see if go on . if you have the book you can bench test the pto or bring it to the john deere dealer and they can test it for you .

OHM out the PTO clutch and check for voltage at the unit connection. Talk to the dealer on what the OHM spec is on the clutch and compare your read with theirs. If that is good and you have no voltage, start at he battery and check voltage til you find the bad part. Check across each connection or relay until you see a differential.
