    when i angle to the right and up the cylinders come to a nice gentle stop, but when i angle to the left the cylinders come to an abrupt stop and it's noticeable.
    any ideas what this might be, I don't want to let it go too long and cause damage, let alone the shock wave felt when this happens.

    I agree with cam 77, I would take it off truck, check what might be out of alignment. If it didnt do this from day 1 I would definetly check er out.

    I think its something in the coil pack area.

    My plow does the exact same thing. Something to do with a poppet. One direction its smooth as can be, the other slams stops, causing recoil, moving the entire truck jerking sideways....

    I cleaned all connections to mirror finish, replaced all pins, super complete fluid flush with fisher blue, no differences.

    As posted above a fish stick will stop this as it has soft stop circuitry.
    The problem is the sudden deactivation of both the motor and vale solenoids with the joystick controllers.

    This is true. I've swapped my fishstick onto my father in laws MM2 and his jerking/sudden stops stopped and it was smooth. My plow always "coasts" to a stop.

    T:rolleyes: This is interesting as I noticed that my new XV slams back harder than my first one did and they both had a joystick???? Same story from the dealer he called them on it and they said it is normal .............. I dont think so either............

    I have a 8' HD 2009 and i noticed the exact same thing. I use a joystick controller as well. I used it 2x and noticed it was stoppong real hard when angling left, and smoth stopping right. I brought it back and the dealer told me it was functioning fine and that is it. Have had no problems with it to say of , but maybee i will try the fish stick if it will stop this, anyone eles solve this with the fish stick instead of joystick?

    Normal for all the 5 fisher plows I've had. has to do with the when angling right Both the lift and angle poppet work.

    Mine does the same thing when angling left, the stops are abrupt at any spot. Right is fine. Adjusted the cylinder relief valves, no change at all. Switch to a fish stick with the cushioning circuitry did very little for the left, did help the right some. Every now and then it chatters going up as well. I have a video of this here with the joystick... audio helps.

    the fishtick does have what they call smoothstop technology. wich does come to a smoother stop left and right over the joystick. it could be a poppet problem

    Same here.... I have two fishticks and they both do the same thing. Smooth-stop when angling RIGHT, abrupt stop when angling LEFT.

    This is an interesting thread.
    I happen to have a new fishstick that i just got on ebay for this season that has the smooth circuitry and noticed the "coasting" left and right whereas the joystick had the abrupt stopping that everyone talks about. So with that said, +1 on the buying a new style fishstick.

    I tried a brand new fishstick while it softenned the right noticably the left hardly changed. Watch the video i posted its pretty harsh!
