I have a Toro 42 zero turn mower and the blades stop turning while mowing. The PTO switch knob melted. I replaced the PTO switch and the blades turned for 5 min. and then the PTO switch melted again.


Elertric blade drive clutches are a real pain when they go wrong
It sounds like a electrical short is causing the wires inside the switch to heat up beyond the safe melting point thereafter five mins the circuit gets between the fault gets broken as the switch fails the blades stop and the switch melts a bad eaRth corroded may cause this check the deck safety switches are not exposed e.g. they been damaged and the decks metal is shorting them out
a wire has been stripped of protective covering and is touching some metal shorting out something that vital to the blade controls operation the switch is getting a overload and subsequently melting your might need an lawnmower engineer to diagnose to the fault fully and repair

Not receiving power to the PTO Clutch connector.


It may well have burnt out the pto switch itself if there was that much power draw.

Electric Blade Clutch is shorted or if you are lucky the wiring to the clutch is grounded. Many times the wiring to the clutch is caught in debris or twigs etc. and pulls the wiring out and cuts and grounds it.

Eletric PTO is not working


The PTO draws a pretty good current, so a weak or loose contact in the switch, or in the connections on the back of the switch, could cause this overheating. But it could also happen if the PTO clutch itself or the wiring to it has a short. If the mower's still under warranty, get the dealer to diagnose and fix it. If not, then I'd measure the resistance of the PTO clutch - should be about 2 ohms - and make sure the wiring to it isn't shorted. If all that is OK, then just replace the PTO switch and any melted connectors and wiring. Good luck!
