The Dipperfox SC850 is the most powerful stump crusher in the lineup, designed for excavators in the 14–30 ton range with hydraulic flow rates of 29–61 GPM. Built for large-scale forestry, construction, and land-clearing operations, the SC850 delivers maximum torque and cutting power to remove even the toughest stumps with speed and efficiency. With a 34-inch width and a cutting capacity of up to 36 inches in diameter, it is engineered to handle oversized and deep-rooted stumps that other machines cannot. Unlike conventional stump grinders, the SC850 operates at low revolutions, with a maximum speed of 60 RPM. This low-RPM design dramatically reduces flying debris, noise, and operator risk, making it safer for use in both rural and urban environments. Rocks and obstacles are pushed aside instead of being thrown outward, reducing the risk zone and improving safety for operators and bystanders. At the same time, its quieter operation makes it a strong choice for municipalities, contractors, and forestry professionals working in noise-sensitive areas. Despite its compact weight of approximately 900 lbs with packaging, the SC850 is built with heavy-duty construction for demanding professional use. Its combination of extreme cutting power, safe low-RPM design, and large capacity makes it ideally suited for forestry, utility, municipal, and construction contractors. Whether used for land clearing, stump grinding, or site preparation, the SC850 is a reliable, high-performance attachment that allows immediate replanting and ongoing site development after stump removal.
