Hey, I don't know if I was the last person on Earth to learn this or not but just in case... If you use a rear blade to move snow, consider turning it backwards, cocking it a little, and pulling it. Turning the blade backwards keeps it from digging in, cocking it keeps the snow off for the most part, and pulling it keeps the 3-point hitch doing what it was designed to do. I read this advice in a forum here, tried it, and wadda-ya-know? It works like a charm (on 750 of gravel driveway).
