I have a 350 feet long gravel drive and I have a Ford Ferguson with a front loader and a grader blade. What works best for me is to turn the grader blade around backwards so it doesn't dig in and set it at a 45 degree angle. This does OK as long as the snow isn't deeper then 6 inches. Otherwise then I have to do more complicated and creative things with the tractor like leaving the front end bucket down and pushing the snow off the drive.
