Hi My name is***** will be glad to try to help. Are you referring to quick connect fittings coming apart? If so the only fix is to replace both male and female ends unless there is another problem with excessive pressure in the circuit which can be confirmed with the use of hydraulic test gauges. Let me know

All tips and couplers have been replaced all 5 sets .

Thanks for the update. Verify your pressures are within specs and check for a restricted return in that circuit as well as a relief valve sticking causing too much pressure in the circuit. Let me know

Hi, Did you get this resolved?

A JD TECH finally came out Monday and said it was plumbed incorrectly or hooked up incorrectly all this time.
Humm, we purchased it from you an you hooked it up at the jd store?
He corrected the connection configuration.
Working so far. Thanks
