    Has anyone figured out how to bolt a sno-foil on with out the nuts and bolts constantly loosening up, I have been fighting this issue for years, now the MM2 is doing it also just like the MM1's did. If I put a tack on the nuts they seem to eventually break.

    im assuming your talking about a steel version, not a poly version. what i have done to quite a few friends plows when they start the coming loose stage is tig the nuts solid to the bolts after they tight on the bottom side of the nut(away from blade) and with a solid tig bead around them they have never come loose, and after a week i did take my matco impact and broke three off in a few seconds just to make sure there was a way to do so in case of replacement..
