DB330B knapsack brush cutter mower coal consumption revolution. Coal consumption leather knapsack mower life focused on reducing direct coal powder burning, natural gas, electricity and other clean energy alternative dispersion of small coal-fired boilers. Accelerate the promotion of efficient pulverized coal furnace DB330B brush cutters, chain phasing out inefficient furnaces. Development of ultra-low-emission coal-fired power plants, natural gas emission standards and strive to achieve by 2020 active inefficient, handheld mower emissions of non-compliance or upgrading furnaces basically eliminated, all to achieve discharge standards, further to the electricity consumption of coal and other key industry concentration. Brush cutter is also known as piggyback mower, can actually carry can hand carry, it is mainly used to sweep large areas of lawn edges or trim shrubs hay. Brush cutter trend is to use new materials to further reduce weight; low vibration damping engine and advanced anti-vibration device and the rational allocation of parts to reduce vibration on the human body; improve the machining and assembly of mechanical precision, improving intake and exhaust system to reduce noise; the addition of a variety of security devices, to improve operational safety; additional shrubs shredding device on hanging brush cutter, cut shrubs simplify cleaning process.
