Treat Yourself｜GrindLazer HP DC1021 G DCS(Depth Control System) Gas-Powered Scarifier｜ Other Products

The Graco GrindLazer HP DC1021 G DCS Gas-Powered Scarifier is a high-production walk-behind scarifier engineered for demanding concrete and asphalt surface preparation, line removal, and inlay applications.
 Designed for professional contractors and pavement maintenance crews, this machine combines a powerful 21 HP Vanguard® gasoline engine, Graco's advanced electronic Depth Control System (DCS), and a 10-inch cutting width to deliver exceptional cutting precision, consistent performance, and reduced operator fatigue. Its reverse "Up-Cut" cutting direction makes it ideal for removing pavement markings, preparing inlays, grooving, and aggressive surface profiling. The LineDriver system is required for operation, providing increased productivity and superior machine control.
Product Information
The GrindLazer HP DC1021 G DCS is part of Graco's High Production Series and is built for contractors performing large-scale line removal and concrete surface preparation. Its reverse "Up-Cut" cutting action efficiently removes thermoplastic markings, paint, epoxy, and other coatings while providing the power required for grooving and inlay preparation. When paired with the Graco LineDriver system, operators can complete projects faster with greater accuracy and significantly reduced fatigue.
Graco's electronic Depth Control System (DCS) eliminates manual measuring and guesswork by allowing operators to quickly adjust cutter depth to accommodate changing surface conditions. The DCS Controller features a programmable zero point, displays active cutting depth, and supports both English and metric units. Fully encapsulated electronic components are protected from vibration, dust, moisture, and harsh jobsite conditions for dependable long-term performance. A remote momentary switch allows operators to adjust cutter depth while maintaining both hands on the machine for maximum control and safety.
Powered by a commercial-grade 21 HP Vanguard® gasoline engine with electric start and Donaldson® heavy-duty air filtration, the DC1021 G DCS delivers reliable performance and extended engine life. Additional features including InstaCut Technology, the Extreme-Duty ProStart System with centrifugal clutch, TriBelt drive system, Fat Track™ front swivel wheel, EasyGlide™ wheel mount system, vibration reduction technology, and an integrated vacuum port combine to maximize productivity, maneuverability, and operator comfort.
