Under load and sometimes not under load the backhoe boom will drop to the ground when the stick and boom are horizontal to the ground. I replaced the pressure relief valve on the spool valve for the boom, but the problem still exists. Does anyone know if it could be a bad pressure relief valve on one of the other spool valves within the bank of spools or a bad pressure relief valve some where else in the hydraulic system. The boom/stick quickly goes to the ground, but I'm able to quickly lift it back up.
