GrindLazer HP DC1520 E DCS(Depth Control System) Self-Propelled Electric Scarifier, Low-Speed Pulley Kit

Graco GrindLazer HP DC1520 E DCS Self-Propelled Electric Scarifier, High-Speed Pulley Kit

The Graco GrindLazer HP DC1520 E DCS Self-Propelled Electric Scarifier, High-Speed Pulley Kit is a heavy-duty, high-production walk-behind scarifier designed for precision surface preparation in commercial and industrial environments. Built for demanding concrete and asphalt removal applications, this machine features a 20 HP electric motor (480V, 3-phase), Graco’s advanced electronic Depth Control System (DCS), and a 16-inch cutting width to deliver consistent performance, reduced operator fatigue, and highly accurate material removal. The High-Speed Pulley Kit is optimized for diamond and PCD tooling, making it especially effective for coating removal, profiling, and surface preparation work requiring controlled aggression and precision.

Product Information

The DC1520 E DCS is engineered for environments where electric power is preferred or required, such as indoor facilities or low-emission job sites. Its self-propelled hydrostatic drive system allows operators to precisely control forward speed, improving consistency across large surface areas while minimizing physical strain.

The integrated DCS (Depth Control System) removes the need for manual depth adjustments or guesswork. Operators can set a zero reference point and then adjust cutting depth in precise 0.01-inch increments using the control interface, with real-time feedback displayed for accuracy and repeatability. This ensures uniform surface profiling across long runs and large slabs.

Powered by a 20 HP, 480V electric motor, the DC1520 E DCS provides quiet, low-emission operation compared to gas or propane models, making it suitable for enclosed or regulated environments. Its heavy-duty steel chassis, low-vibration design, sealed long-life bearings, and quick-change side plate contribute to durability, ease of maintenance, and long service life. A built-in vacuum port allows connection to dust collection systems such as the Graco LazerVac™ for improved jobsite cleanliness.
