I plow a long gravel drive with a back blade on my tractor. I do as others have described, that is push with the convex side of the blade till the ground is frozen. I tried the guage wheels, and the slides like a truck snow plow has, but found they were more of a PITA than any kind of help, so I took them off. If you have a gravel drive, you will move some gravel onto your lawn in the winter, just no way around it.
Here's one thing I do in the spring that I haven't seen anyone mention. Might sound kind of strange, but works well for me - In the spring, when everything starts to melt, I plow my snow banks back into my driveway. If you catch it just right, when the ground is still frozen, you can do this with no damage to your lawn. What you are doing is moving all of your gravel back into the drive. Typically, I can find a day where I can do this in the morning, and by night the snow is mostly all melted so my driveway isn't plugged up for a long period of time. I started doing this a few years ago, and most years I don't need to do any raking at all after everything is melted (I hate to rake..).
