I have a 450D excavator that was working the other day and mid swing it was like someone lifted lockout lever and now there is almost no response from the controls. If you start the machine and put the lockout lever into run mode there is no response unless you hold the travel levers in reverse for about 15 seconds then the machine will track backwards. The pilot pressure is good going into the valve bank and there is oil in the machine. Any info would be appreciated!
