KING KUTTER'S PROFESSIONAL DUAL EDGE LAND GRADER is the perfect tool for driveway and gravel road maintenance and construction. It fills pot holes and low spots, while removing the high spots and redistributing the material to achieve a perfectly finished roadway surface. It uses 1/4" thick side plates and 1/2" thick wear plates, along with 3" X 3" heavy tubing to make up the main frame that ensures that your new land plane will perform well on farms and ranches as well as in landscaping and contractor applications.
