John Deere 4310
Hi folks,
Looking for some help with my John Deere 4310 e hydro. My machine runs fine, after about 35 minutes of use the pto shuts off. It’s like an electrical issue after warm up. I can hear and see the main pto turn on and off with the button but the mid pto doesn’t. I can let it cool for a bit then the mid will start back up for a bit. I switched the relays in the fuse box with the lights. Just to isolate a bay relay. I bypassed the seat switch and replaced the solenoids all three on the valve bank. I even removed clean and tested then switched the plungers in the valve bank. I also opened the switch panel and tested the on and off pto knobs all tested good. Running out of ideas any help would be appreciated.
