Fantastic tool. I have not done any thing with our drive in more than 5 years. I began working with the gravel grader and after about 4 hours I had all of my holes filled and the drive was level and crowned. I still have work to do as the center of my lane was full of weeds and I will be using the gravel grader to continue clearing weeds from the center of the lane. I am absolutely sold on the gravel grader and have nothing but compliments about it and the job it allows me accomplish. I also found the staff at ABU to be great people to work with from the first phone call to my purchase.
