Reply To: John Deere Grader 770G – constant pressure in Load sensing Line

sincerely appreciate all the insights and support I received from the great minds in this forum. I’m truly glad to be part of this platform. My heartfelt thanks to everyone who took the time to respond to my post. I’m pleased to inform you that the issue has been resolved. For anyone who may encounter a similar problem, here are the steps I took: Connected a pressure gauge to the pump. Adjusted the pressure reducing valve. Observed the pressure drop from 1500 psi to 500 psi (system operating pressure was initially 1500 psi). Adjusted the load-sense relief valve until it reached 2000 psi max operating pressure. The machine is now operating perfectly. However, I’m still curious about why Deere incorporated a load-sense relief valve into the system, as the adjustments above seemed to function similarly to tuning the load-sense and pressure compensator spool. Thank you all once again.
