Plow drop, Normal ?

    Dumb question… :blush2:

    I had a 20 year old Fisher that would not stay up when driving around (would have to raise the controls every few miles). I chalked it up to old age and leaking hydraulics. Now I have a brand new Curtis electric hydraulic and I noticed it does not stay up either. I just drove 14 miles and it dropped and inch or two on me twice. Is this typical or should I call the dealer and have them look at it?

    That is not normal..... I would take it back to the installer and have them check the bypass valve for a possible leak. That should hold for a very long time.

    OK, this is strange. I drove home and the plow stayed up tight, it didn't come down at all. I see that as good news BUT when I was inspecting the plow tonight I noticed something else. The center piston (to raise and lower plow) had oil on the outside of the case. Not just a little, it ran down frame too. Now, is that normal? (little bit of fluid working it's way out the top of that piston after 4-5 hours of plowing).

    I'd bring it in and make them look at it... Be a PITA with them too and just don't accept, "they all do that - it's normal"...

    I mean come on, my old OLD Fisher only leaks a little fluid because of a loose hose fitting... There's no leaks anywhere else on all three cylinders...

    No that's not normal either. Could be a loose packing nut.

    Thanks all. I'm sure if they give me any BS a call to Curtis that starts with " You ever hear of plowsite.com?" will help me get it resolved :nod:
