I have a Ford 4610 that the 3 point is sticking in the up position under certain conditions. It will move up and down with no attachment without problems. However when I connect my belltec tm 48 to the rear hydraulics and raise the 3 point it will not lower with the controls. If I disconnect the remote hydraulics it will raise and lower without issue. If I kill the tractor with the 3 point up after a few seconds I will hear a klunk and the 3 point will drop. It has new fluid and filter. What am I looking at?
