Many thanks TomG and everyone else. I haven't had time to experiment but I've looked closely at the lines and valves. I assume I have an open centered system, and my hydraulic cylinders have only two hoses per. Looks like hydraulic oil comes into the valve manifold at the side. There are staggered ports in the center of the manifold, two per valve, and the return is on the opposite side of the valve manifold. I traced the lines to one of the loader cylinder's and one of the curl cylinder's, and they seem to be opposite of each other i.e. paralled port of lift to cylinder rod end of cylinder, and same port for curl valve goes to opposite end of cylinder from cylinder rod, if that makes sense. Simple matter to swap hoses and I will try that.
What doesn't make sense to me is that with hydraulic oil coming in on the side of the valve manifold, seems like the first valve would be a priority valve. On a centered system that was described, with the priority valve in operation, how would the secondary valve get any oil??? Seems like the priority valve would 'block' any pressure until the valve is released.
Also, doesn't seem reasonable that this is just a capacity problem, since the system IMMEDIATLY fails when I try to use both valve at the same time. Engine rpm's are a factor in how responsive my loader controls are but not a factor in the original problem definition.
Last thing is I don't believe I have a 'float' capability or position with my loader unless we're talking about lowering the bucket to the point where it just 'floats' on the ground, that I can do. Even at that I'm skeptical since I can lift the front of my tractor about 12 inches off the ground with the bucket. Anyway, just status for everyone who responded. I really appreciate your efforts and this board. What a great resource for a beginner like me!!!! JJ

About the hydraulic top link, is this something I would have to fab up myself or are kits sold somewhere?? If I need to fab it, where is the best place for parts?? I have Northern Tool catalogue and they have a few things but I assume there are other places (besides local dealers) to shop mail order. Also, is it common to adjust one side link longer or shorter than the other in order to tilt one side of the blade (box scraper) say to put a crown in the middle of a driveway??
