Husqvarna YTH 2448 mower PTO switch is getting hot and melting the plastic internal parts. Any ideas on what is causing the overload? The mower deck will shut off when the switch melts and the push/pull button will pull out of the housing. wires do not appear to be getting hot and clutch will pull in everytime until switch gets hot.

bad safety switch --or pulley / bearing failure on deck

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

I used to see this on the Kawaski engine machines with an electric clutch, they put a diode between the two clutch wires so as so as to stop any electrical feed back throught the clutch, when the machine is running without the clutch engaged it can turn into a generator.

Hi, check or replace the switch on the seat, basically its not telling the safety system that you are on the seat. Regards Phil.

check the safety switches start with the one on the clutch it is a double switch

cheers pauly46

The PTO switch has failed. There is an internal spring and plastic parts in toggle switches that keep them in the actuated position. It's not practical to take the switch apart to fix it, but replacement switches are readily available - probably $12 - $20. It's a good idea to disconnect the negative terminal from the battery before you do any electrical work. Be sure to put the wires on the corresponding terminals of the new switch. Good luck! Please rate if you find this helpful, thanks.

I have a Husqvarna 2448 I just rebuilt the engine someone before changed the motor the four wires 2 go to charging like the other 2 go it discharges when you kick the pto in I put a new clutch on it the 4 wires are my problem

I have a husqvarna yth2448 mower whitch the pto switch burns out and pull apart .Blade stop turning and mower remains running

try unplugging the pto, start the mower, then engage the pto switch. If the fuse still blows trouble is somewhere in the mowers wiring if not the ploblem lies in the pto. hope this helps
