    Hi folks. I had this symptom today where the motor would spin, but no plow movement. Just prior to that I had noticed I was low on fluid, so I topped it off. I let the truck sit for a while while I searched the Fisher website. Went back out and re-plugged all the connections and solenoid connections. I cycled through all of the joystick positions and it finally started moving again.

    Could this have been an air bubble? I'm just wondering if I need to take apart reservoir and look for plugging or disconnected pick-up?

    could have been froze up, we've had a lot of cold weather and they will freeze up. If it was the common fallen pickup tube problem it wouldn't have fixed itself. Might be a good idea to drain the fluid, pull the resevoir and replace the suction filter, I've replaced a couple of mine this year, some preventive, one was really slimed up. That would make it starve for oil as well. What worries me is I've only seen slimed up filters with plows running that newer blue fluid. Never saw that problem before.

    Why was it low?
    Did you fix the leak?
    air bubbles will work them selves out as long as the resivor is full of fluid.

    The worst from a air bubble is a spungy ram. If all the air doesn't work it's self out.

    It's possibel somthing was clogging the screen.
    Water frezing up?
    When was the last time you changed the fluid and cleaned the scren?

    What type of HYD fluid are you useing?
