GrindLazer HP DC1538 G DCS(Depth Control System) Self-Propelled Gas-Powered Scarifier, High-Speed Pulley Kit

Graco GrindLazer HP DC1538 G DCS Self-Propelled Gas-Powered Scarifier, High-Speed Pulley Kit

The Graco GrindLazer HP DC1538 G DCS Self-Propelled Gas-Powered Scarifier, High-Speed Pulley Kit is a heavy-duty, high-production walk-behind scarifier designed for aggressive concrete and asphalt surface preparation. Built for demanding commercial and industrial applications, this machine combines a powerful 38 HP Kohler® EFI gasoline engine, Graco’s electronic Depth Control System (DCS), and a 16-inch cutting width to deliver high material removal rates with precise depth control and reduced operator fatigue. The High-Speed Pulley Kit is optimized for diamond and PCD cutters, making it ideal for coating removal, profiling, grooving, and large-scale surface preparation.

Product Information

The DC1538 G DCS is engineered for high-production surface removal tasks where speed, consistency, and control are critical. Its self-propelled hydrostatic drive system allows operators to fine-tune travel speed based on surface conditions and application requirements, improving productivity while reducing strain during extended use.

The integrated electronic DCS (Depth Control System) eliminates manual depth guessing by allowing precise cutter adjustment without stopping the machine. Operators can set a zero reference point and adjust cutting depth in 0.01-inch increments through the control interface, with real-time depth feedback for consistent results across large surfaces. (Graco)

Powered by a 38 HP Kohler® EFI gasoline engine with electric start, the unit delivers reliable performance for tough jobsite conditions. Its heavy-duty steel frame, low-vibration design, and sealed long-life bearings are built to withstand continuous industrial use. A quick-change side plate simplifies drum removal and maintenance, while the integrated vacuum port supports dust control systems such as Graco LazerVac™.
