    Plow issue
    Hey guys I have a brand new xv2 and when I back drag the passenger wing doesn't stay locked. Also that same wing is slower going into the scoop but moves at the same speed going to v. Otherwise the plow works great.
    Pressure relief valve or solenoid would be my guess. What do you guys think think?
    No leaks.

    if its brand new why not bring it to the dealer?… it definitely sounds like a solenoid isn't staying closed. powering up at the wrong time.

    They are 4 weeks booked. If it was something small I'd just fix it

    There isn't another dealer you can go to.The only thing with fixing it yourself is making sure you don't void the warranty

    I have to call around some more. I called 2 closest both with the same wait time.

    If you are a business your dealer should be able to find a spot to get you in.

    Sounds like back pressure relief valve needs adjusting

    Rod end relief valve. Sadly they are not the easiest thing to get to, hidden behind side covers of pump. Are you trying to move plow while back dragging? As for the one wing a bit slower, this is common. No need to worry about it.

    No I'm not. If I start off with it straight and back drag, the passenger side will end up being fully extended. It doesn't hold the pressure.

    If you have it straight and push the blade doesn't drop back to V right?

    9 out of 10 times this is caused be debris in the rod end relief. But like I said they are hidden by the side covers. Always have the possibility of a damaged valve or valve o rings but I would put money on the relief valve. I will normally reset the check ball while I have them out.

    That is correct TPCLandscaping. And is only the one side.


    Kimber, I'm calling a few dealers around me when they open to see if they can get to it tomorrow. (snow coming this weekend) and if not I'll take a look at it.

    Do you happen to know which relief it would be? I'm guessing one of the bottom 2 on the passenger side.

    If you go onto fishers website you may be able to print off a trouble shooting guide. I know you could for the old plows. As long as you can follow schematics and some flow charts they are a big help

    Digging this up

    I took it to the dealer and they said that the relief valve wasn't adjusted right. They said they adjusted it. It's still doing it just not as bad. I'm going to try and adjust it this week. Do I go in or out with the screw to increase the pressure

    Ended up fixing it today. The relief valve was bad, I switched it with the drivers side and it started to do it. Put a new valve in and it's fine now.
