Hydraulic control valve

[vic32ft]

Have M95 that has valve under seat that doesn't turn. How much pressure do I dare apply trying to turn? How many turns should it turn for left to right?
Thanks

Does the drop rate of your 3pt lift arms need to be changed? That's all the knob does.

I would spray some good lube around the knob and let it sit for a while. It may be rusted up.

Mine was frozen also when I got it. I guess the PO didn't use the valve. Anyway, I sprayed it with PB Blaster spray and let it sit for a while, then I used a wrench on it to work it back and forth just a little at a time. It finally freed up and works like new.

Just an update. Used PB and a little pressure and works again. Thanks for the help.
