I have an ex220-3 that is sporadically pulling the engine down with levers in neutral even with pilot safety on.I know i am saying a lot here i but have checked electrical system over and over and at this point i don't think it is electrical because it will do it with the pump at min. stroke ,Deere also checked it and said aok but it was working OK when he was here.It has a new pump & solenoid valves. I ran it with dr.ex on when it did it only pump delivery pr. went up everything else stayed normal. Has anyone ever had trouble with the unloader valve ?:Banghead Thanks for any help..
