Pro Trimmer head's hybrid design cuts light grass up to medium brush. The heavy duty string line quickly severs smaller grasses and pulls larger sized material into the stainless steel teeth for efficient cutting that saves wear and tear on the string line. This patented dual action design minimizes stress on the strings， increasing their life and reducing down time. The string lines and the cutting ring are easily replaced for years of reliable commercial duty service.
