3500 Internal combustion mower cutters 3500 portable coal production revolution. 435 on the eastern part of the principle of brush cutters do not build new mines, according to the central region, "a retreat to build a" model appropriate follow-building, the development of the western region in accordance with the requirements of large-scale, modern, intensive, ecological mower 435, around the large coal power base and modern coal chemical projects, focusing on green building safe and efficient coal mines, coal mines by 2020 safety green light brush cutter production reached 30 million tons. Coal continues to accelerate the elimination of backward production pace can. Overhead valve design: aloof efficiency and performance, overhead-valve engine as its name implies, the valve located above the combustion chamber of the engine rather than the side of overhead valve design allows more smoothly blended gas inhalation. fast, so that the exhaust is more thorough. Efficient combustion process for a large power output increased compression ratio, while reducing the carbon and subsequent maintenance needs, location and shape of the combustion chamber to ensure excellent high-temperature equilibrium; easily deformed so that the cylinder, reducing fuel consumption , extending the life of the engine. 1.5 hp maximum power, displacement 31cc, four-stroke engine oil, 0.65 kg fuel capacity, fuel type, 93 # or more U-shaped handle with both hands to shape, power transmission, automatic centrifugal clutch, spiral bevel gear, shock mounts clutch cover. Displacement: 35cc Weight: 7kg four-stroke brush cutter (oil, gasoline added separately), easier to use.
