Hi, New to the forum. Could use some help. I have an L2002. The hydraulics for the 3 pt hitch will not raise. I’ve drained all the old fluid and replaced with new put a new filter on and still nothing. The motor oil is not any higher, so it’s not draining into the engine. I can’t seem to find a metal screen filter. Although if I manually lift the 3 pt hitch it will stay where I lift it. Any help would be greatly appreciated. Thanks
