After changing oil and filter which was plugged behind solid, tractor is still doing same stuff, I notice where people are talking about this supercharge line, I have a open center hydraulic system and that line is still their, I can also hear a faint whine at mcv pump which it sounds like it sucking air,
I have to rev engine up to get pressure. If I delete or remove supercharge line what all will that do?

at an idle if you don't have presure at your remotes you will probably need a new pump

If the tractor was that starved for oil it may have burned up the hydraulic pump.

Have you tried the 5 gallon over fill that might be a very cheap repair compared to replacing the pump. It is a solid recommended first response. Jim

What is this so called super charge line? Something from one of the remotes to the MCV? Did you while cleaning the MCV when off take a file and just make sure there were no burrs and rough spots, like chisel marks from getting it off the dowels, and all the gasket was off and smooth. These are a must for successful results. I just did my 806 and ran a file flat over the whole valve surface. It will help with pulled threads at the holes and just makes it smooth to seal better. Mine had a couple places where somebody had used a chisel and roughed it up more than the file could fix. I put a dab of Permatex on those spots to help fill in some.
