Abstract <br><br>Disc harrow is one of the more important soil preparation machines in tillage and soil preparation machinery, which is mainly used for crushing soil after ploughing in dry land, soil loosening and weeding before sowing. It is widely used in operations such as shallow tillage and stubble removal after crop harvest, soil moisture preservation in early spring, and soil crushing after tillage. It can also be used as cover seed operations after plane sowing. At present, it has been widely used at home and abroad. Its main characteristics are: passive rotation, strong grass cutting ability, certain soil cutting, soil crushing and soil turning functions, low power consumption, high operation efficiency, and it can work on the cultivated land and It can work on uncultivated land and has strong work adaptability. <br><br>Keywords: agricultural and forestry machinery, tillage

Summary.<br><br>The disc is one of the more important whole-land machinery in the tilling machinery, which is mainly used for the crushed soil after ploughing in drylands, as well as the loose soil and weeding before planting. It is widely used in shallow tillage after crop harvest, early spring preservation and crushed soil after tillage, and can also be used as cover planting operation after planting by aircraft. At present, it has been widely adopted at home and abroad, its main features are: passive rotation, strong ability to break grass, with a certain amount of cutting, crushing and turning the soil function, low power consumption, high operational efficiency, both in the cultivated land operations and in the unceded land operation, work adaptability is strong.<br><br>Keywords: agricultural and for for-forest machinery, tillage
