[QUOTE="brdgbldr, post: 126140, member: 7474"] So if it isn’t electrical It has to be a valve /spool issue. There are seals on the pressure release valve that can be replaced but since the pressure seems to stay I doubt that is the issue, but it could be stuck. The auxiliary spool has a couple of springs on it that can go bad or break. The spool can also get scored and not work properly. The auxiliary load check has a spring in it also. You may want to call a dealer and see if they will help with diagnoses. Some dealers are real good with this, others not so much. If you take it into a dealer they charge, at least my dealer, $140 per hour plus parts. A mobile tech is $160 per hour plus parts and travel time. The advantage is that they can hook up a diagnostics computer to the machine and they have gages to check the hydraulics. A backhoe may work on your machine since the hydraulics seem to get stuck on in the forward position. But if you can’t release the pressure in the auxiliary hydraulics you will not be able to hook up the couplers. [/QUOTE]
