Objects of the research are crests of potato, the physical and mechanical properties of their soil, energy-material-saving, tools which provides qualitative working process and their technological processes. Objectives of the study: Working out of objectives for factors of highly useful potato diggers, energy- material-saving priorities of technological processes and energy-material-saving and factors of highly useful in digging, cribbling, mincing of potato digging machines. Work out of construction by studying the shape and size of the potato bed, the physical and mechanical properties of the soil and soil clods, as well as potatoes during excavation in the summer and autumn periods; Working out more acceptable construction of development of a rational design and technological intensive scheme for the operation of a potato digger, the study of the destruction of soil clots of potato beds; Justify and work out parameters and construction of excavating the tuberous layer and energy-saving digging tools of the potato digger; To develop the study of the process of separation of potato tubers from the soil with minimal damage; Prove the parameters and choice of design and justification of the device for laying tubers on the surface of the field; Provide accomplishments of agro technical applications recommended parameters of working bodies in the construction of an energy-saving potato digger, study of the agro technical and technical and economic efficiency of its application. The scientific novelty of the study is as follows: Worked out construction of the support-milling device are derived and regularities of the degree of destruction of soil clots of potato beds depending on its parameters and operating modes are determined; It is based on a schematic diagram and the design of sectional shares that, due to the digging of the necessary part of the potato bed, provide a minimum resistance and exclude the heap congestion; Analytical dependencies allowing to substantiate the rational values of the intensifier parameters for soil separation consisting of a wavy ripper that provides a uniform distribution of the heap along the width of the elevator and raises the path it travels along its working surface and thereby increases the completeness of separation of impurities with minimal damage to the tubers; Developed the design of an improved swathing machine for laying tubers of potatoes, consisting of pitched sieves wound with rubber, which, by reducing the impact force and the height of the fall of the potato heap, provide minimal damage when laying potato tubers; 53 Implementation of the research result: On the base got results of the scientific study on development energy-material saving potato digger, providing raised fullness digging under minimum damages of the club potatoes: It is designed energy-material saving potato digger, providing raised fullness digging under minimum damages of the club potatoes with provision for soil-climatic conditions of the Republic and is introduced in design agency JC "BMKB- Agromash" (the reference Ministry rural and water facilities of the Republic Uzbekistan about introduction result to thesises for 02/23-596 from 21.11.2017). With the result that is created possibility of the reduction of the consuption combustible - a lubrificants in one season on 230-250 kg, reduction of the damage club has accordingly formed 15%; It is designed, energy saving potato digger, provided with wad-supporting device, sectional plowshare, wave-like looseners, providing destruction wad, fullness separation and exclusive ground at digging of the potatoes and is introduced in farming facilities Yangiyul region. Introduction in practical person potato diggers enabled the reductions of the losses club before 18% and increase to capacity before 29% (the reference Ministry rural and water facilities of the Republic Uzbekistan about introduction result to thesises for 02/23-596 from 21.11.2017); It is designed, energy saving potato digger was introduced in farming facilities Kuyi-Chirchik and Chinaz regions Tashkent area residing in subservience Ministry rural and water facilities of the Republic Uzbekistan (the r
