    My Poly V has the drop speed of a guillotine. How do I adjust it? Also, how often should I service it/replace the the fluid? Thanks.

    On the pass side, back side of the lift tower facing the bumper. Need a 3/16 allen wrench and a 9/16" open end wrench to break the jam nut loose. Turn the allen screw clockwise (in) to slow the drop speed down. Check it in both vee and scoop positions as it will always drop faster in scoop than it will in vee. Have to tune it to your liking.

    That's how you keep the snow off. After you adjust it you'll be mad that it's to slow!

    You're right about that. But I had to set mine slower. I was afraid I'd be waking people up in the middle of the night. (my favorite time to plow - less idiots)
    The nine footers make a pretty good thud on a concrete drive.

    I adjusted mine to drop a little faster last year and its nice but the plow is now just starting its 3rd year and during the course of the last 2 storms, BOTH blade return springs broke. The hook snapped at the block in the center. Now I need to slow mine down a bit.

    I tried to adjust mine last night, but can't break the jam nut lose from adjustment screw. The adjustment screw turns fine, but I can't break the nut lose to lock it down in a new position. Can I pull the screw all the way out and take it inside/heat it up to break it loose? It unscrews pretty far, then doesn't feel like it wants to come all the way out and I don't want to crank it too hard if it isn't supposed to come all the way out. Sorry, this is my first Boss after a million Westerns. Thanks.

    It'll come out. Just may be a little snug from lack of adjustment/weather. Add a little penetration fluid and gingerly thread it in and out a few times to clean the threads.

    I mean can I take the whole screw out of its hole and bring it inside. The nut it just stuck on the screw in its place, but the whole screw moves in and out of the hole fine. I don't want to strip the allen head and the allen wrench was bending like crazy trying to break the jam nut loose. I just need to know if the drop speed adjustment screw can be pulled all the way out without damaging anything. Thanks.

    Also, can I switch to a V plow if I have the right connector already on my truck and get the right controller? If so, which is the right connector?

    Yes, screw the enitre jamb nut/allen screw out as an assembly so you can work with it.

    Just change to a vee blade controller and you can run the vee. No other changes needed (the beauty of a Boss).

    But, you can actually run the vee with your straight blade controller in a pinch if need be, you just can operate the wings independently... it'll function just like a straight blade.

    The drop speed is good for me. The wing retract speed could be slower, but it works.

    Plow is approx 7-8 years old. Serial # would tell for sure.

    You can run the pro wings on the older plows with the boxed rear side but you need to cut a large hole in the box in order to attach the pro wings onto the back side of the blade sheet. Or the other option is to change the attaching pin on the wing to a longer one to allow it to go fully through the board sheet and protrude out the rear of the box section. Either option works fine...

    is it harmful to the plow when it drops? I just got my boss v today on my f250, and when i drop it, it shakes the whole truck and sometimes seems pretty damn hard...maybe i'm just being worrisome?

    I sometimes wonder why boss puts springs on the wings and western and the rest don't
