My driveway is one half mile long. Some places along its length, the snow gets much deeper than other spots. I do my first swipe in the shallowest spots then nibble away at these drifts until I get the driveway widened out. One time this season the snow drifts were almost three feet high (and 100 yards long) in the middle but much shallower near the edge of the road near the ditch. As I went for the low spot I got pulled off the road and into the small drainage ditch and stuck. I try to plow with the wind and drifts to keep it down but sometimes it does get away from me. Would it have been better for me to raise the blade slightly and stay in the middle of the driveway away from either side or do I want to always leave my blade all the way down? This situation doesn't happen very often but it does happen.
