I use a rubber edge, long enough to roll under the plow (9" I believe, with holes centered, so 3-4" hanging below cutting edge), and it never removes gravel. It basically pushes a small amount of snow down to the gravel, and the rest off the gravel. I can run angled, or whatever without issue. I also dont have to wait for things to freeze to run it.Yes I do, there is a guy on YouTube I was chatting with, he has the same setup as mine. He's the one that told me to get the rubber edge, said it won't push off the crusher run either, but to me it's worth a try. But yes, once frozen in the past with the plow I've always been able to run with the shoes almost not touching, but I never removed them completely in case I ran into uneven spots, sort of like setup for anti-scalp.
I clear my 400+ feet and my neighbors 600+ feet of gravel drive using it.
I do not use the blade for much else but snow, so no need to have a more solid edge on it.
