That means no need to pre-mix fuel + oil, less exhaust smoke / smell, and often quieter and cleaner operation. 4-stroke brush cutters tend to have better fuel efficiency and are more suited for longer work sessions (gardens, farmland, heavier vegetation) because of their smoother, more stable engine performance. They are often a bit heavier than 2-stroke models, but the tradeof...
