We live on a long gravel driveway, the last bit of which is steep and often develops "heaping" of gravel from tire spin. Used to have a family member "blade" our driveway with his tractor from time to time, but he moved away. I have a zero turn mower, and I saw someone pulling a unit like this on their gravel driveway, so I decided to give it a try. Cheaper than many of the "chain" harrows and works perfectly on my driveway. Now I mow my grass and my driveway :)
