The development of energy and resource-saving methods and technologies for strengthening and restoring the working bodies of agricultural machinery will increase their abrasive wear resistance and durability by using materials from machine-building waste and reduce the cost by 10-30 percent without reducing operational characteristics. (Research purpose) The research purpose is in increasing the abrasive wear resistance and durability of cultivator legs by surfacing powder materials obtained by electroerosive dispersion from solid alloy waste by high-frequency currents. (Materials and methods) Authors obtained a powder for research on their own experimental installations of the CCP "Nano-Center" of electroerosive dispersion from waste of sintered hard alloys of the T15K6 brand. The microhardness of powders and coatings on microshifts was measured using the PMT-3 device, and the hardness of coatings with the KMT-1 microhardometer was measured using the Rockwell method according to GOST 9013-59. The microwave-40AV installation was used to assess the wear resistance of materials of working bodies of tillage machines. (Results and discussion) In the course of laboratory wear tests the relative wear resistance of samples hardened by high-frequency surfacing currents significantly exceeds the wear resistance of non-hardened samples made OF 65g steel, accepted as the reference standard. (Conclusions) Based on the results of experimental studies, the article proposes a new resource-saving technological process for strengthening the working bodies of agricultural machinery through the use of materials from machine-building waste, which allows increasing the abrasive wear resistance of working bodies by 1.5-2 times due to the use of tungsten-containing materials.

Abstract The development of agricultural technologies, the mechanization of the cultivation of ordinary crops for a long time has gone differently in different ways. The working bodies of agricultural machines process various materials, the number of which is increasing. In addition, the way the same material is processed often changes when trying to improve agricultural technologies. All this forces us to create new mechanisms of agriculture that were previously known. The use of replaceable gear bodies on flat cutting cultivators helps to reduce the energy intensity the process and improve the quality of non-falling soil. To protect against it, various agricultural techniques are recommended: plowing along the entire slope, deepening the arable layer, the formation of irregularities on the surface of arable land in the form of holes, intermittent furrows. The article describes the mechanized protection of the soil of the technological process and technical means for growing crops on erosive lands on the slope. Methodology for improving agricultural machinery for working on the slope of erosive dangerous lands. Ways to increase the stability of the movement of agricultural machines on slopes to improve the quality of technological operations are justified. The operating mode of the active disk needle is described.

The paper considers the issues of increasing the reliability of agricultural machinery through the use of reinforcing processing of recovered machine parts by plastic deformation, which provides an increase in the quality of their surface layer during recovery. The operational stability of the piston fingers and the upper heads of the connecting rods restored by vibration reinforcement on the engines working in the mechanized agricultural complex was carried out: tractor - agricultural machine - car. Studies have shown that the amount of wear of piston fingers restored by the vibration deformation method is 1.23 times smaller than the traditional method of recovery, which confirms the effectiveness of vibration technology. Technological processes of restoration of discs of diggers of beet harvesters, discs of coulters of grain planers, plow blades with use of vibrating vibrations of the processing tool are developed and put into production. The results of these developments showed an increase of 1.21 times the time of beet harvester harvesting with the diggers' wheels with the vibration-strengthened method; an increase in technical use factor of 1.07 times, compared to new 65G steel wheels. To improve the reliability of the PLN-5-35, PLN-3-35 plows, the technology of restoration of working bodies - blades is developed and introduced into production, which provides for increase of their durability and durability. The coefficient of technical use of the plow units with the blades restored by the developed technology is 1.01 times higher than that of the plow units with the new blades made of 65G steel. The wear rate of the toe, width and thickness of the blade are 1.51 respectively; 1.22 and 1.27 times less than the new 65G steel blades. The results of the study of vibrating reinforcing processing of working bodies of agricultural machinery help to increase their resource, which provides increased reliability of machines.

AbstractThe article examines agro-technical requirements of machine implements with disk working bodies and is aimed to investigate the existing and alternative methods of depth regulation during soil tillage by the mentioned implements. We defined the machines performance indicators significantly affecting the plant potential release not considered previously. The study results were obtained via the soil tilling depth regulation by the disking speed, the change of an incidence angle of the working batteries, and by the use of the additional load mounted on the machine frame. The article presents a two-year research results obtained in 40 different land plots of the Sumy region (Ukraine) using domestic and imported machines, with wheat and buckwheat as crops. To ensure the study accuracy, the methodology was based on the CND 46.16.02.-96. Agricultural Machinery. Quality Indicators Nomenclature (Catalogue of Normative Documents, published in 1997). The research results demonstrate that the tilling depth depends on the manufacturing plant default settings, the speed regime, and the machine load. For the experimental data analysis, the Least Squares Means method was used. The research presents alternative methods of changing the tilling depth applicable for any machine aggregates with disk working bodies, and its results can serve the agricultural machinery designers.

Improvement of crop production technologies is based on the development of agricultural machinery in which the trac- tor power plays an important role. In crop production, agricultural crops require variable attention during their growing season and consequently, different production costs. The most expensive are row crops which in the process of development require a lot of inter-row tillage of plantings and sowings. The implementation of such tillage involves the control of weeds, plant fertilization, operations for chemical protection of plants from diseases and pests. Therefore, it becomes evident that the agricultural machinery used in the production of such crops must be adapted to its use in planting and sowing crops at different stages of plant development. Thus, both the aboveground and the parts of the plant located in the soil should not be damaged and oppressed by the working bodies of agricultural machines and the engines of energy facilities. It becomes obvious that tractor fleet of agricultural organizations should have both powerful general-purpose tractors used mainly for plowing, continuous disking, cultivation and sowing using wide coverage units, and row-crop tractors designed for inter-row tillage. There are methods for developing an optimal fleet of machinery for agricultural organizations which differ in production trends and in size of agriculturally used areas. Taking into account the possibility of using modern means of digitalization and artificial intelligence which can significantly improve the quality of technological processes and control them, it is possible to develop technologies for the production of row crops. Of all tractor models mentioned in the research, the following models have the best agrotechnological characteristics required of the general-purpose row-crop tractors: Fastrac 2170 produced by the British company JCB and LTI 162.5 tractor that is to be produced in Izhevsk, Russia.

The analysis of equipment for basic boardless plowing and surface tillage revealed the absence in the market of agricultural machinery of multifunctional units capable of reliable and efficient performing both types of tillage by means of one machine. The constructive-technological scheme is offered and the basic model of the unit with replaceable working bodies is developed: flat hoes for performance of the basic processing of soil at 14-25 сm with the creation of a mulch layer and cultivator hoes for carrying out the surface and shallow tillage at 5-14 cm. To assess the effectiveness of the basic model of the unit in 2018 in field conditions a research was carried out, during which the main agrotechnical indicators of the quality of soil treatment were determined. Studies have shown that the degree of crumbling of the soil at the basic boardless plowing of sod-podzolic medium loamy soil at a speed of more than 6.5 km/h exceeded 80 %.  For shallow tillage to a depth of 12 cm  in the range  of operating speeds above 7.0 km/h the amount of a soil fraction up to 25 mm was not less than 70 %. The unit stably sustains the working coverage width and the installation depth of tillage. The variant of the unit with a set of working bodies for the basic boardless plowing in the entire range of operating speeds provides an average tillage depth of 19.5-21.0 cm at an installation depth of 20 cm, with working bodies for shallow tillage - of 11.5-12.0 cm at an installation depth of 12 cm. The height of roughness of the field surface after the basic boardless plowing was 20.7-23.0 mm, for shallow tillage – 12.5-17.0 mm. The results of the research showed that the basic model of the multifunctional unit can perform the basic boardless plowing and shallow tillage in compliance with the basic agrotechnical requirements without the use of replaceable adapters for additional tillage of the top layer of soil. The use of additional working bodies will make it possible to form more highly specialized versions of the machine based on the basic model of the unit.
