The HR35 Series Retractable Box Scrapers meet dirt moving and soil contouring needs of landscapers, contractors, nurseries, sod growers, farmers, ranchers and municipalities. Soil contouring productivity is dramatically increased with utilization of the hydraulically controlled retractable scarifier. The front blade mounted on the moldboard is ideal for soil redistribution and soil leveling. A second blade mounted on the hinged rear gate further enhances the ability of the Box Scraper to redistribute and level soil. Both the front and rear blades are replaceable and can be flipped over to extend blade life. (HR25 photo shown as reference.)
