That valve looks likea Gresen model 300. Notice the pipe plug above the valves spool. If so, the rear port needs to be plugged. A model 300 is only made to run a single acting cylinder. The spool is machined on one end along with the internal passage blocked by that plug to allow the flow to go to tank. There is also a plastic check ball that goes in there but it probably has been close to 15 years since I looked at one. Look real hard for some casting numbers or letters. I am out of town and can look in my Gresen parts list when I get back home. J.

Got to work on tractor yesterday....and you were very close. After removing about a half inch of paint, the valve says GRESEN 550 and in smaller font 8/12/68.
Pulled both hoses off the cylinders and put in a bucket so could watch them side by side. When I pulled on lever it looked like an identical amount of fluid came out of both hoses..when I pushed on the lever, the hose connected to the port closest to the lever actually had a small amount of oil come out of it at a slight pressure; nothing came out of the port furthest from the lever. Put the hoses to a T on the port closest to the lever...loader went up fine, but would not go down..actually kept creeping up a bit. 300 pound son could stop and get it to come down real slow. Putting T on port furthest from the lever, loader again went up fine, but would not go down...didn't creep though and son was able to easily make it go down. With the T in either port, the loader went down nice as you please with the tractor shut off... So, looks to me like controller is unique to this loader/tractor and is shot, I now know more about hydraulics than I ever thought I would at this point in my life. I know what a replacement controller would cost and a friend and I are going to take the controller to a place in Richmond tommorrow and see what it will cost to rebuild this one...would love to keep this thing stock, but am not a purist when it comes to too much money. Thanks to all for the help, suggestions, and recommendations.
