Question about John Deere 420,1020,2010,2020,2510,2520 Tractor Float
John Deere La150 54 inch deck when the Eletric PTO switch is activated it works for a moment then gets hot and melts 2 terminals mower only has 40 hrs on it.
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!
