Hi,
Though'd I put this out for everyone's knowledge.
Last week the rear PTO on my John Deere 4410 stopped working; just quit in the middle of bushhogging.
I have the tech manual so I was able to troubleshoot it. As it turned out, it was very easy to figure out and fix.
Basically, the PTO is driven by a hydraulic clutch, and a solenoid valve controls the supply of pressure to the clutch. In my case, both wires broke right off at the solenoid, immediately stopping the PTO.
When I found a new solenoid was $30 and neither of the two closest dealers had one, I realized I had to fix it. There was almost no wire sticking out of the solenoid, but I was able to tin it with a soldering iron, and then solder the wires to the solenoid.
It worked (so far).
On my tractor, it appears the root cause of this failure is an unsupported wiring connector. I tie wrapped it to a nearby hydraulic line.
I encourage everyone to check their tractors and tie up any loose wiring, especially unsupported connectors. The same solenoid is used for MFWD and mid PTO; they are at risk for the same loss of function.
regards,
Mac
