Features: According to the process of soil processing, agricultural tillage machinery can be divided into plowing machinery, land leveling machinery, and subsoiling machinery, etc. To adapt to the current economic development needs of agriculture, tillage and land preparation machinery should take a combination of large, medium, and small sizes as the development direction, with a focus on the development of medium and small-sized machinery in the near term. The process of processing various types of agricultural land using appropriate mechanical and electrical power, operational tools, and tillage techniques is called agricultural tillage mechanization. Specifically: Before sowing or planting of various crops such as grains, vegetables, forage, and timber, including all stages of growth and development, as well as during fallow periods, soil and surface processing are carried out according to need to create surface conditions for crop growth, improve coverage, vegetation conditions, and soil layer structure. Whether it is China's traditional agriculture, farmers' production practices, or scientific research, it is currently believed that the processed soil should be flat, with loose topsoil, granular soil structure, and firm subsoil, with the depth of the topsoil layer varying depending on the root needs of the crops and soil characteristics. This book includes: Plows; Rotary Tillers; Disc Soil Tillage and Land Preparation Machinery; Paddy Field Rakes and Other Land Preparation Machinery; Weeding and Subsoiling Machinery; Straw Crushing and Returning to the Field Machinery; Tillage and Land Preparation Machinery, etc.
