    Fisher, MMI, SEHP. When the plow is lifted, should I be able to move the plow blade back and forth, manually, albeit it with some effort?? or does this signify a greater problem.

    Thanks

    No you should not be able to. Might be the crossover valve. Did anything happen? Hit something hard?

    No. Just noticed it this last storm with the heavy slush. I'll start thread searching the crossover valve.

    Look up fishers website for your plow and go through the guide. It should show you all the places and pieces that ate involved

    my fisher hd was doing the same thing, turns out the dealer never completely filled it with oil which allowed air to enter the pump and it would cavitate. Filled it with oil to proper quantity and now its all good
