Carolina Smooth Roads Carolina Smooth Roads “CSR” utilizes the Savannah High Speed Road Grader in our dirt road maintenance applications. The Savannah Grader, combined with the Unimog U-500, provides us the capability to travel on the road at normal speed and operate our equipment on site – all with one vehicle. With this combination, we are able to provide our customers with monthly service at greatly reduced costs when compared with traditional road maintenance methods and equipment. Savannah High Speed Road Grader: CSR uses the Savannah High Speed Road Grader for our road grading business and also represents the equipment in North and South Carolina for sales. The Savannah Grader is unique in that it scarifies, reclaims, re-crowns, smoothes and compacts one side of a dirt road all in one pass. Having only four functions, the machine is very easy to use – simply drop the blades, drive and your smoothing the road!
