Has anyone bumped up there pressure relief valve yet to get alittle more lift capability, I'm thinking of doing it to mine but would like to get a gauge on it first to see where I'm at and not to increase it to much,
Look through above the RH rear tire. Behind the PTO selector lever you will see a squarish box that has an allen head screw and a lock nut protruding from it towards the rear of the tractor. The backhoe would likely block access from the rear. Loosening the lock nut and turning the screw inward will increase the pressure. Spec is 2133 PSI. Using the loader valves, the spec on the connectors is ISO-7241-A 3/8. You will see that there is also a similar type of adjuster below the loader valve.
Great information thank you, is the hydraulic line in the back that feeds the backhoe and then couples togethor the same connectors as the front loader ones also
