Ideal for confined areas, SC90 and SC130 portable stump cutters remove stumps up to 3 feet in diameter. The cutter wheel takes 2 9/16-inch wrenches and requires only a few minutes to change. The cutter wheel consists of four sections so that if a section becomes damaged, it can be changed without replacing the entire wheel. A dual-grip, rubber-mounted handlebar minimizes vibration and provides a comfortable grip variation based on machine angle and operator height. For safe operation, the cutter wheel comes to a complete stop in less than 6 seconds. The SC90 features a 9-hp engine, and the SC130 has a 13-hp engine.
