Background

In recent years, with the stable and rapid promotion of urbanization construction and the rapid development of agricultural science and technology, rural and agricultural industrial structures are changed by turning over the sky and covering the land, and a considerable part of cultivated land is changed from planting traditional grains and economic crops to the directions of facility agriculture, greenhouse vegetable, melon and fruit bases and the like, so that the traditional large-scale tiller cannot meet the requirements of modern agriculture. In addition, the rapid development of urbanization leads to the accelerated transition of rural young and old workers to cities, and the rest of middle-aged and old workers cannot bear heavy farming labor and are difficult to adapt to complex machine tool operation, so that a new type of small-sized tiller needs to be researched to fill the defects of the large-sized tiller in the operation projects. In order to meet the market demand, the mini-tiller is put to practical use, and the volume size of the mini-tiller is far smaller than that of a large-sized tiller in terms of volume size. The types of mini-tillers on the market today include walk-behind mini-tillers and self-propelled mini-tillers, whether walk-behind or self-propelled mini-tillers, which all include a frame, an internal combustion engine (diesel engine) disposed in the frame, a tillage cutter disposed at the rear of the frame and driven by the internal combustion engine, and a pair of wheels disposed at the bottom of the frame and driven by the internal combustion engine.
