I’m working on a skid steer that won’t unlock the hydraulics at all I have checked all the safety switches they are all working like they should be have also checked fuses and relays and made sure the diod fuses are good. Anyone had this problem before?

Working on mine as well. Check the codes section on the display. If you don’t see something there it could be a range of things like:
Door not closed, lap bar not down, brake switch not working, controls out of calibration or stick malfunction, wheel speed sensors or just loose wiring on all of those.
