John Deere 4710 PTO not working easy fix

This is a focused diagnostic-and-repair video for a specific PTO fault on the 4710 (and related 10/40/4000 series machines): the PTO light and switch show on but the PTO doesn't engage. It walks through testing 12V at the solenoid coil, removing the plunger/valve assembly, freeing a seized valve button with WD-40, and bench-testing the coil's magnetism. Best for owners with this exact symptom, especially backhoe owners who rarely use the PTO.

Appears to be an experienced tractor owner/buyer who works on backhoe-equipped machines himself and shares hands-on repair knowledge from personal experience.
