Sno-Way Plow Stopped Operating this morning

    We have a 2 year old Sno-Way Contractor Series MegaBlade mounted on 2003 Dodge 3500 dually. It has worked really well until this morning.

    We used it for 10 minutes to clear our driveway then stopped to wait for other crews to show up. When we got ready to leave, it would not lift or move side to side.

    Here is what we can describe at this point:
    At the end of the 10 minute plow, we brought it back to center on the truck and it moved very slowly. Then we dropped the blade to wait and then nothing. It does sound like the hydraulic motor is running. We've disconnected all wiring (including the control box next to the hydraulic motor) re-greased and reconnected.

    All of the solenoid connections are showing hot at 12.5v - do they all operate open?
    The hydraulic fluid level was slightly low and we topped it off.

    Thanks for reading! Any ideas?

    Or ... Is there a bleeder valve on the top of the solenoid bank? I'm beginning to suspect an air lock.

    How cold was it outside? sometimes the fluid can freeze up. Mine did it this morning.

    Thanks!

    The filter screen was frozen clogged preventing the fluid from passing through. Turns out moisture creates a slime that gathers around the screen. The moisture will freeze while the hydraulic fluid will not. A hair dryer to warm the area and the plow worked again. We are servicing the plow today to clean the filter screen and replace the hydraulic fluid.

    We thought about the possibility of freezing early on, but discounted it since we had used the plow for about 10 minutes before it shut down.

    Thanks for the comments.

    What fluid were you running? Have you cleaned the filters in the manifold where the hoses connect?
