GrindLazer HP RC1625-G Gas-Powered Rotary Scarifier

Graco GrindLazer HP RC1625-G Gas-Powered Rotary Scarifier

The Graco GrindLazer HP RC1625-G is a high-production gas-powered rotary scarifier designed for contractors who require fast, groove-free pavement marking removal on concrete and asphalt. Powered by a 25 HP Kohler gasoline engine, this machine features three independently adjustable rotary cutter heads capable of removing markings up to 16 inches (406 mm) wide in a single pass. It is engineered for highway striping contractors, airport maintenance crews, municipalities, and commercial paving professionals who need exceptional productivity without damaging the pavement surface.

Unlike traditional milling equipment that can leave grooves or require extensive pavement repair, the RC1625-G uses Graco's rotary cutting technology to remove traffic paint, thermoplastic markings, epoxy coatings, and temporary construction lines while preserving the integrity of the pavement. The combination of adjustable cutting width, floating spring suspension, manual depth control, and heavy-duty construction makes it ideal for continuous commercial operation.
