GrindLazer Self-Propelled Gas-Powered Scarifier with Depth Control

Graco GrindLazer HP DC1538-G DCS Overview

The Graco GrindLazer HP DC1538-G DCS Self-Propelled Gas-Powered Scarifier with High-Speed Pulley Kit is Graco's highest-production walk-behind scarifier engineered for large-scale concrete and asphalt surface preparation. Equipped with a powerful 38 HP Kohler EFI commercial engine, hydrostatic self-propelled drive, electronic Depth Control System (DCS), and a 16-inch cutting width, this machine delivers exceptional productivity for contractors performing heavy-duty scarifying, coating removal, pavement marking removal, concrete leveling, grooving, and industrial floor preparation.

Designed for demanding commercial applications, the HP DC1538-G DCS combines precision electronic depth control with high production rates to help operators maintain consistent cutting depths while reducing fatigue on large projects. The integrated High-Speed Pulley Kit optimizes drum speed for diamond and PCD tooling, making the machine especially effective for removing epoxy coatings, waterproofing membranes, traffic markings, and other difficult surface materials.

Its hydrostatic drive system maintains smooth, consistent travel speeds over concrete and asphalt, while the rugged steel frame, industrial components, and contractor-grade design provide the durability required for daily use in commercial, municipal, and infrastructure applications. Whether preparing warehouse floors for epoxy coatings, removing thermoplastic road markings, restoring parking structures, or profiling bridge decks, the GrindLazer HP DC1538-G DCS delivers professional results with maximum efficiency.
