Issue - When doing certain tasks, the PTO will suddenly disengage after no specific amount of time (could be 20 min or 2 hours from cold start). Check that the voltage supply matches the allowed voltage of the solenoid coil. This works for mechanical, electrical or hydraulic debugging: a technique known as the divide and conquer method. The solenoid in a PTO system is essentially an electromagnet that pulls the lower plate hooked to the blades upward toward the flywheel providing kinetic energy from the engine. Check that the armature/spring assembly moves freely inside the tube. R. West. Often, the malfunction of a solenoid valve can be attributed to easy to fix issues, such as dirt in the valve (80% of the cases). The solenoid in a PTO system is essentially an electromagnet that pulls the lower plate hooked to the blades upward toward the flywheel providing kinetic energy from the engine.
