touch control help please

Another item I find with fast hitch is when tractor is not running either leave hitch all the way up or all the way down. That lift assist spring can create presure on system in any other position. When hitch is all the way down spring has an over center effect that reduces any presure. When all the way up bolt adjustment in end of spring stops presure. Nowhere does IH say that is a must. I just find now into 45 years with one of these, they just work a whole lot smoother if one is careful not to leave presure or load on system when not running. At least reduce it as much as possible.

How long is it since your touch control fluid has been changed? And how long since screen was cleaned? What happens if you hitch to a plow or some implement similar weight, is problem worse or better? Another item to check is spring assist for hitch, it has adjustment that can be off? The long bolt going into spring from end, if not adjusted properly can stop rockshaft before it is all the way forward. Just play with it a bit keeping close watch on changes and when they occur. Process of elimination. It may well be your touch control needs a kit, but we should explore other possibilities first. Usually the kit happens when problems occur on both valves.
