It is characterized by flat work, simple operation, and strong cutting ability for the objects that need to be cut, mainly grasses, and is suitable for high-yield grasslands and large parks. The lawn mower relies on the relative shearing movement of the moving knife and the fixed knife on the cutter to cut the grass, which is characterized by neat stubble cutting, and the power required is small, but the adaptability to the forage grass is poor, easy to block, and it is suitable for flat and natural grassland and artificial grassland operations. In the mid-80s, rotary lawn mowers began to be produced and used. Cutting grass is driven by the impact of the blade on the high-speed rotating cutterhead. With the improvement of science and technology, the working capacity of the newly improved lawn mower products has been enhanced a lot, and the speed has been improved a lot, which saves the working time of weeders and saves a lot of human resources.
