I have a JD 490e. It was working fine. I stoped for lunch, came back all functions were slow. Checked oil and changed filters. When I work the functions the pump doesn't seem to kick in. If I close the bucket all the way and hold it against the thumb you can hear the pump kick in and functions work at correct speed. Two years ago the dealer put a new main pump and went through the load sense valve. When the machine sits over night it'll work for 5 or 10 mins then acts up with the slow function problem... Almost like when it gets warmed up it starts acting up.
