    I have a 2008 810 plow that raises and stays up and lowers but won't stay up in the middle position. I have tried just about everything flushed the whole system out, changed valves and bleed air out. I am stumped any help would be appreciated.

    Do you mean it won't stay up unless you raise it all the way up? Or are you referring to the angle of the blade?

    If it wont stay in middle position you have a bad valve. Pull out the lowering valve and replace it with a new or with the up valve. If that fixes it, then you know what it is.

    Or check for fluid. You could also have a leaky hose or fitting. Had some leaky wipers on my lift pump a few years back. Didn't notice for a while as it sits in the aframe.
