    As the title states, I have a 2 plug MinMount plow with an SEHP pump set up on it. The plow goes up and down with no problems, but when you go to move it left and right, the plow wants to move and sometimes slowly does (and when I mean slow, I mean S L O W). What should I start checking for, all grounds and connections are fine obviously and the pump is running when you go to move it left and right. Where should I start?

    Alright update, I took out each cartridge and cleaned them, bench tested them and put them back in. I replaced the one I thought was bad and still nothing. I'm getting pressure in both the lines going to the angle pistons. What could be causing this inside the valve block? Any ideas? Thank you!

    Maybe water in the fluid? thats freezing the valves?

    Just a thought...
