´╗┐The SPS10 is a high-output drum-style scarifier ideal for surface preparation on a wide variety of surfaces including asphalt, concrete, and steel. This all-purpose scarifier has a maximum cut width of 10 inches and can be paired with a wide assortment of cutters and accessories to remove markings, level uneven surfaces, and groove for inlay.


The LNX8 is the ideal choice for when you need to remove lines without the grooving pattern or ghostlines typically associated with drum-style scarifiers. The rotary action of this scarifier hovers over the surface, breaking the coating while simultaneously scraping across it, leaving a smooth, beveled edge without grooves or undulations.
