DB 995 hydraulics

I have a 995 that the lift arms will raise but they will not go back down. I checked the spool valves next top the seat under the cover and they are free and not stuck. My next step is to pull the 3point off to disassemle the main valve. What next any suggestions
 
Take the cover off the housing on the right rear of the tractor and see if it is a mechanical issue or a hydraulic one.

The 2 valves you can get through the top cover you pulled are the hold and bypass, not spool. They can be the problem if it doesn't go up, but not if it won't go down.

The DB collectors site has a decent fault finding guide that you can go through step by step. could be a stuck/missadjusted spool valve, stuck latching valve or a mechanical issue...

The spool valve you can get to through that cover on top, it is about and inch rear of the bypass and hold, has 2 nuts on top with a screw driver slot in the center. Don't try to adjust it in the tractor, you need a dial indicator and have it on a bench to adjust. you can try to pry it up and down with a screwdriver though...

Latching valve the valve body has to come out of the tractor to work on.
