    When I lift my Diamond ( older ) plow it VERY SLOWLY starts to drop by itself. Can someone please help me identify what the problem is and what I need to do to fix it. It is a fully hydraulic plow system. THANKS in advance for your help!

    Your having leak down which would indicate that you have a bad seal. Likely time for a rebuild.

    Depending on what pump you have, there is a adjustment screw for blade drop speed. Check this out before you go rebuilding the whole unit.

    Take the other advise up above, and if that doesn't pan out, I think you have a leaky valve in the control valve block. You did say it is a fully hydraulic system, right? I don't know where you would look for a fluid schematic. Meyer might have one on the web.

    edit: Are you sure you don't have any external fluid leaks? That will allow the weight of the plow to push fluid out and drop the plow if it is leaking.
