Graco GrindLazer HP RC820 H Hydraulic-Powered Rotary Scarifier

The Graco GrindLazer HP RC820 H (Part #25P471) is a heavy-duty hydraulic rotary scarifier engineered for high-volume pavement marking removal and concrete surface preparation. Designed to mount directly to low-flow hydraulic skid steers, the RC820 H provides contractors and municipalities with a fast, efficient solution for removing painted traffic lines, thermoplastic markings, epoxy coatings, and other surface materials without creating deep grooves in the pavement.
Unlike traditional milling attachments, the RC820 H utilizes interchangeable rotary cutter assemblies and a floating spring suspension that follows uneven concrete and asphalt surfaces. The result is cleaner marking removal, improved surface quality, and reduced damage to the underlying pavement.
Built with a heavy-duty all-steel frame, universal quick-attach backplate, adjustable depth control, and integrated dust collection capability, the RC820 H is designed for demanding highway, airport, municipal, and commercial pavement maintenance applications. Its compatibility with most low-flow hydraulic skid steer systems makes it a versatile attachment for contractors looking to maximize existing equipment while increasing productivity.
