    try fliping the control box over :rolleyes:

    So what happens when you try to angle left, does angle to the right or does it go left to. (i guess I am asking, are you stuck to the the right right now?)

    And, will it lift?

    If everything works right except for the one directional angle, try pulling the coils and cleaning the valves. There are three valves that have to be used for the movement of your plow.

    Here is the best way I can explain it.

    On the drivers side of the plow headgear, on the side of the pump, there is a Valve Manifold Box.
    Take plastic cover off. There are three coils inside there.
    Take the S3 (bottom left) coil and valve out and clean them. (Have a catch pan for any oil the runs out)
    Clean and lube the valve or replace it.

    I think the S3 (bottom left) is your problem, I think it is stuck in the (in) postion so every time you push right, the fluid is still going to the left cylinder.

    If that doesn't get it try cleaning and lubing S2 (top left)

    Clean S1 if you want, but that is only used to lower the plow.
