I have the land pride snow push. The bottom I use a rubber edge on the gravel and it does great. But when I need to get close to a building and pull snow away, or get at some icy spots on the gravel, I just lift the loader up, and adjust the push so the top is now the bottom. Then drag backwards. It clears very well. You obviously need a push box that has a pull back edge though, I think most do but its usually an add on option.
A good way to tackle that property if you can is to just push down, drive right up to the top, turn around and then start. I have slight hills at both my entrances, and sometimes if it isn't scraping as cleanly as I want facing uphill, I just drive up the hill, then push it down.
Love my snow push, I still use my blower to touch up stuff here and there, but I've largely stopped as I get more comfortable with the pushbox.
