    Hi everyone,

    Pretty long time reader, first time poster....

    I have a Sno Way ST with down pressure. Today after coming out of a stack, the plow dropped. Each time I lifted it, it would just drop. I'm suspecting one of the fittings of the hydraulic hose of the lift cylinder. Does this make sense that a cracked fitting would cause a loss of pressure so it wouldn't stay in the raised position?

    Thanks much for any insight. I've always enjoyed reading posts from so many knowledgable people!

    No a cracked hose does not make sense:nono: you would see big puddles of fluid and the plow would not lift.

    First I would check to see if all the wires are attached to the coils.

    Does the unit raise with the same spped it always did?

    Thanks for the response, Basher. The plow raises like normal. I will check the connections. I appreciate your input.

    On second thought, it does seem to be little more labored to raise.

    Also look for frayed wires that might be grounding out, if a mouse or something chewed some wires the snow/water could be providing a current path and holding a valve open or partially open. How long since it's been serviced, fluid changed, etc? What's the temperature there?

    I've been bad. I haven't changed the fluid. I bought the plow new in '05. I sent you an email.

    Thanks,
    Jon

    Having been able to visit with a helpful man in Hibbing, MN, and using the plow for a few minutes, it started to work properly. I was plowing all day.

    Thanks, Basher, for the suggestions. I know I need to do a lot of service work on my plow.
