RESEARCH AND DEVELOPMENT OF A MACHINE SYSTEM FOR COMPLEX MECHANIZATION OF PRECULTIVAL TREATMENT OF AGRICULTURAL CONDITIONS IN THE BUKHARA REGION. Norov Sobirjon Negmurodovich. LONG STATE - The object of the study is the use of auger working body for the current and operational planning of agricultural land. The aim of the work is to develop the theoretical background for the use of a screw working body before the scheduler bucket and to conduct experiments in laboratory conditions with the proposed working body. The method of work - when conducting experiments in a soil channel 60 meters long and 1.5 meters wide, an appropriate soil background was created that meets the agrotechnical requirements of pre-sowing field planning. Agrotechnical indicators were determined before and after the passage of the planner. The thrust force of the working body was determined by existing methods. As a result of the experiments, it turned out that with the use of a screw working body, the total traction resistance of the scheduler increases by 8¿ .10%, and the alignment of the site meets the agrotechnical requirements before the sowing background.
