Everyone see heads along a driveway get squashed, especially when there is no block or curb to define the different height levels of grass and driveway. Worse spot I see is the corner of the grass where the driveway meets the road. Often heads are squashed more than 4 inches below the sod surface, bad drivers anytime or during the winter months when snow/slush hides the edge and the ground is mushy. Or the threads on the bottom of the head are driven/snapped into the head body. Around here many driveways have no block along the edge. And the area where the driveway meets the road, the entrance is not square. Often splayed wide the last 3 feet or so, a fake apron. Again, no curbs delineate the grass area from the road. Heads get run over often. Or the snowplows scrape the lawn edges, taking out some heads Yeah, more service work for all. But what if it is your own yard or someone wants you to specifically solve that problem. By not using curbs or blocks at the driveway edges. Somewhere here recently someone mentioned putting 6" round heavy duty PVC pipe around the heads. Like a turret. Won't stop a snow plow. Someone else mentioned "throwing the water into the corner" from 2 angles. So, what do you do for this?
