As you said, it's an issue with some. I bought my top link from Prince Direct and I've never had any problem with it leaking down or "giving" under pressure. However, my tilt cylinder is driving me nuts. It won't hold up very long without having to readjust. When making rounds in a 15 acre patch with a bush-hog I'll be dragging one side of the cutter after a few rounds if I don't! I'm going to take it to a local hydraulics shop and see about getting the dual piloted checkvalves added, but if this is too expensive I'm going to replace it. I'm not sure of the manufacturer for the tilt cylinder, as it was one the dealer came up with when I bought the tractor.
