    few days ago we had a snow storm in ct, i run a fisher mm1 strait blade on a 94 f250xlt big block, i made a pass with the blade down and when i went to raise it it moved slowly then dropped it an try'd to raise it again but didn't move, but thing is the motor sounded as if it was moving the plow but it wasn't moving the plow maybe a inch if that, so we checked the plugs an control let it sit and still didn't work, then when i went to put the joystick in the up spot on the controller the motor got stuck an i had to unplug it for it to stop. not sure whats wrong with it, checked the fluid its full. any help would be awesome any questions id be glad to answer

    not sure if this is your problem but according to the owner's manuals... if the motor gets stuck on it's generally a sign of a bad motor relay.

    just my two cents.

    Check for frozen water in the system

    When is the last time you changed the oil in the pump? I had a similar problem last year, and it turned out there was enough water in the system to freeze in the lines or in the bottom of the pump. Try warming up the pump, and if it starts to work, I'd suggest flush and refill the entire system with new hydraulic oil.
