    The cross over reliefs could just be doing their job. If you are trying to move large heavy or frozen piles the crossover should allow the plow to angle back against the stops to protect the hydraulics.

    The cross over is doing it job...Especially when your trying to push a pile of snow that might be too heavy.. Just think of the valve protecting the rams or not allowing the seals to blow. It relieves the pressure from the rams and allow it to flow back to the tank..

    ok, i understand the purpose of the valves. just seems like its allowing it to move with less and less pressure. where is the valve located? near the selinoids?

    Then I would pull the valves and check them..You might have a bad spring, or something in the passage way.

    I don't know what plow you have..This is for a unimount

    You know there is a pressure setting for the crossover valves. If they are set too low or the spring is weak or broken the blade will move too easy. Check the crossover valve condition and then set it. Usually the manual tells you how many turns from bottom to back off.

    Whats the trick to getting the screws loose without ruining them?

    Which screws? If you are trying to break the slotted screw for the relief valve adjustment their may be locktight on it. You may need to use an inpact screwdriver. That is a thing that you put in the slot and then wack it with a hammer. The screws for the valve cover should be just regular 1/4" hex or possibly they have the torx internal star. If you use the 1/4" socket you need a very thin sided one. I use Snap-on 1/4" drive sockets for that as there is not much room. If you mean some other screw you will have to be more specific.

    Tell you the truth, mine was also hard getting out..The screws wouldn't turn..I spray a little rust remover around the screws..Waited about 15min. Then I tap the screws square just enough to give it a jolt. Then use a screw driver that fit the slot and turn it back and forth. Then the screw came loose enough to were I could turn them both out.. If not just use a little heat to warm up the metal, the let it cool down..DO NOT get it hot..Just warm..4seconds is enough
