Anyone had a problem with seperator coming on very slow and engage header and it drag rpms down so much you cant run the machine.deere checked pressure on top of gearcase and pressure is too low from the 175psi specs,was fine the day before and next day this has happened..running in clean corn..was hoping there would be an easy fix besides rebuilding gear case,im not losing oil out of gearcase either,everything else on machine is fine
