Compatible Machines
The Graco 25P472 GrindLazer HP RC1640 H is designed for professional use with compatible skid steer equipment that meets the required mounting and hydraulic specifications.
- High-flow hydraulic skid steer loaders
- Skid loaders with a compatible universal quick-attach system
- Equipment providing 24–40 GPM (91–151 L/min) hydraulic flow
- Compatible skid steer systems from major manufacturers using a universal quick-attach interface
Compatibility Note: Verify the skid steer's quick-attach interface, hydraulic flow, and hydraulic pressure specifications before ordering. The 25P472 requires a high-flow hydraulic power source and supports an inlet fluid working pressure up to 2,000 psi (138 bar).
Graco 25P472 GrindLazer HP RC1640 H Overview
The Graco 25P472 GrindLazer HP RC1640 H is a high-production hydraulic rotary scarifier engineered for removing markings and materials from flat concrete and asphalt surfaces. Powered by the host vehicle's high-flow hydraulic system, it delivers efficient surface removal for demanding professional pavement maintenance applications.
Three rotary cutter assemblies provide a cutting path up to 16 inches (406 mm) wide. The rotary cutting design removes pavement markings without leaving the grooves commonly associated with traditional drum-style scarifying methods.
Key Features
- No-Groove Line Eraser: Rotary cutting technology removes lines without leaving grooves in the surface.
- Adjustable Cut Width: Three cutter heads can be positioned to remove a path up to 16 inches (406 mm) wide.
- Multi-Point Depth Control: Provides accurate cutting depth adjustment for controlled surface removal.
- Spring Suspension: Allows the cutters to follow surface contours for more consistent cutting performance.
- Universal Quick-Attachment Backplate: Supports fast, tool-free connection to compatible skid loader equipment.
- Heavy-Duty Steel Frame: Built for demanding professional jobsites and high-production applications.
- Dust Removal Support: Includes a vacuum port for connection to a compatible LazerVac vacuum system.

Designed for High-Production Surface Removal
The 25P472 GrindLazer system is built for contractors who need efficient removal of pavement markings from concrete and asphalt. Its three-cutter configuration increases working width while the spring suspension helps the cutting assemblies follow surface variations.
Because the RC1640 H operates from the skid steer's hydraulic system, there is no separate gasoline engine on the scarifier. This design makes hydraulic capacity and attachment compatibility important considerations when selecting the host equipment.
Typical Applications
- Pavement marking removal
- Traffic line and stripe removal
- Concrete surface material removal
- Asphalt surface material removal
- Road and parking lot maintenance
- High-production surface preparation projects
Dust Collection Compatibility
The GrindLazer HP RC1640 H includes a vacuum connection for dust extraction. For dust-control applications, a compatible Graco LazerVac system can be connected to the machine. Proper dust collection helps control airborne debris during concrete and asphalt surface removal operations.
Why Choose the Graco 25P472?
The Graco 25P472 combines a wide cutting path, high-production rotary cutting technology, and hydraulic operation in a jobsite-ready system. Its no-groove cutting design is especially useful when pavement markings must be removed while minimizing unwanted surface channels.
Frequently Asked Questions
The Graco 25P472 is a high-production hydraulic rotary scarifier designed to remove markings and materials from flat concrete and asphalt surfaces.
