Abstract:
Modern machines are subject to progressive wear that occurs at different rates, which leads to unpredictable failures that reduce the reliability and durability of machines. The strategy of maintenance and repair is aimed at eliminating these problems. (Research purpose) The research purpose is in analyzing the basic principles of the strategy of maintenance and repair of agricultural machinery in order to ensure control of the technical condition of machine parts. (Materials and methods) When resource diagnostics is used, , the allowable value of the parameter is set in advance for a part . This value is the tolerance that corresponds to a certain wear rate of the part. The tolerance is set based on the condition that if the current value of the controlled resource parameter during the next diagnosis is less than the set value, then such a part at the current value of the wear rate can be finalized until the next inter-control check. Taking into account the wear rate of the same type of parts from the group when determining the allowable wear during their resource diagnostics becomes an urgent task. (Results and discussions) As a result of research, the article presents "Methodology for determining the main indicators of reliability of parts of agricultural machines with different wear rates" and "Methodology for determining the tolerance system of parts of agricultural machines with different wear rates". (Conclusions) The article presents the tolerance system that reduces the probability of failure of machine parts in operation. During resource diagnostics, those parts whose resource parameters exceed the tolerance are rejected.

Annotation Purpose. Improving the efficiency of the use mobile agricultural machinery by substantiating the rational terms of its maintenance and repair, taking into account changes in its technical condition from seasonal loading, natural-production and agrometeorological conditions of use. Methods. System analysis and synthesis, induction and deduction, system-factor and system-event approaches, graphic, statistical. Results. The conceptual provisions of strategy adaptive maintenance and repair mobile agricultural machinery are revealed, as well as its advantages over the known approaches to the organization of repair and maintenance works are marked. The regularities of seasonal loading of mobile agricultural machinery in farms of different natural-production zones of Ukraine analyzed. A generalized algorithm of the strategy of adaptive maintenance and repair of mobile agricultural machinery has been developed. Conclusions 1. It’s established that the main factors that determine the need for maintenance and repair of equipment are its residual life and operating time, and the factors that determine the possible periods of maintenance and repair of equipment – natural-production and agrometeorological characteristics of the agricultural producer. Predicting the impact of these factors on the processes of using mobile agricultural machinery is the basis for justifying the rational timing of its maintenance and repair. 2. The formation of strategy adaptive maintenance and repair of mobile agricultural machinery based on statistical simulation of the processes of seasonal use of machinery by agricultural producers. Such a model should take into account the natural-production characteristics of the agricultural producer, the characteristics of its technical support, agrometeorological conditions and generate technical and economic indicators of many possible options for adaptive plans for seasonal maintenance and repair of each unit. 3. It’s established that the criterion for substantiation of a rational seasonal adaptive plan for maintenance and repair of mobile agricultural machinery is the minimum total cost of implementing the relevant strategy. The total cost of funds should take into account the cost of maintenance and repair of machinery, the cost of potential crop losses caused by late performance of mechanized agricultural work machinery due to its incapacity, and cost due to underutilization of technical resources. Keywords: rational terms, maintenance, repair, algorithm, strategy, mobile agricultural machinery.

Abstract:
The article considers the current state of the system of maintenance and repair of agricultural machinery, shows the analysis of the existing system and its impact on the economic efficiency of production in the agro-industrial complex. The current state of instrumentation, electronics and computer technology can significantly increase and expand the possibilities of both diagnosing and forecasting based on it. The combination of these capabilities with the progress of agricultural machinery ensures its reliable, highly productive and economical operation. It is established that of great importance in the production of crop and livestock products is the qualified use of agricultural machinery, including its diagnosis, maintenance and technological maintenance and repair. The quantity and quality of the received production, its competitiveness, labor costs, fuel consumption and degree of influence on environment depend on quality and timeliness of carrying out service – diagnostics at technical and technological service. Improving the use of agricultural machinery and reducing the cost of its operation provides the use of technical diagnostics of machines as an information basis for the management of maintenance and repair processes. The practice of using diagnostic tools indicates the possibility of reducing operating costs. This is achieved by increasing the actual resource used, reducing the number of repairs and saving spare parts. To effectively apply existing diagnostics and development of new, engineering and technical workers of agricultural enterprises must have knowledge that reveals the fundamental side of the diagnosis. Measures of preventive influences which provide maintenance of necessary indicators of reliability and working capacity of cars during time of use are executed on a scientific basis, practical use and research of processes of wear and other deviations of details are developed.

Abstract:
Introduction. The aim of the study is to develop the basic principles for digitalization of the processes of providing the diagnostics and repair of agricultural machinery. Materials and Methods. The specifics of agricultural machinery functioning are work in worst-on-worst operating conditions, such as significant abrasive contamination (soil particles, dust and other substances), operation in the conditions of exposure to natural climatic conditions, intensive use during the work shift and other factors that result in a regular need for testing and repairing. These factors significantly extend the time of maintenance and repair works. The study of the information environment for planning the distribution of agricultural machinery by repair enterprises has showed that the methods of this activity are not sufficiently developed. The authors propose a solution to the problem of rational distribution of agricultural machinery for repair and rehabilitation. Results. This article describes the main principles for developing structural relationships of databases used to find rational solutions for organizing repair and rehabilitation of agricultural machinery. Due to the fact that the solution of such a problem is time-consuming and is carried out under conditions that dynamically change over time, a mathematical model for the production environment of repair organizations is proposed, which is implemented by means of computer technology. The requirements for models describing the state of the production system of repair organizations are defined. A model of a generalized production system is proposed. Discussion and Conclusion. The model developed by the authors allows increasing the automation level of processes of distributing agricultural machinery by repair enterprises. The implementation of a new approach to planning repair works and distributing repairable agricultural machinery by repair enterprises will increase the efficiency of repair works, improve their quality parameters, reduce time, and optimize the structure of technological equipment of repair enterprises.

Abstract:
Work job orders for 196 seed drills collected by HADCO (Hail Agricultural Development Company), Saudi Arabia, were used in this study. The work job orders were classified in terms of the parts used and the cost of each item. Distribution of repair and maintenance as listed in the work-job orders was classified as repairs by 55% while 45% was found to be maintenance. Moreover, Classification of repair and maintenance for parts of seed drills was 66% for rapair jobs and 34% for manitinance jobs. Cost ratio term was developed, by dividing the repair or maintenance cost by the seed drill purchase price. The results indicate that the average cost ratio was affected by annual working area. Also repair and maintenance cost decreased as increasing the number of seed drills every year, and due to the increasing number of working area, the costs increased after about 430 ha/year.

Abstract:
An effective technique in the improvement of wear resistance and resource especially wornout friction is provided in the surface parts of anti-friction tribological coatings of various compositions entered in the regular lubrication maintenance of machines and equipment [1, 5, 7–10, 12–17]. Approved since 1930 [10] they during maintenance of machinery and equipment allows 2–3 times to increase their service life, 5–20 % reduced consumption of fuel and electricity, up to 30 % operating costs [7, 9, 10, 13, 14]. Introduction to oil chemically active substances, suspensions of particles of natural and artificial minerals, the oil solutions of the active organic substances, metal salts of organic acids [7, 17], the electric charge consumption less than 1 W [4, 6, 11], creating a wear-reducing coating [2, 5, 8, 12, 15–17], enhance adhesion of the lubricant is technically and economically justified, with a margin of 500–800 % or more [1, 3, 5, 7–10, 12–17]. CIP technical service as part of the overall system of technical maintenance and repair of machines, meets all the periods of their life cycle, and includes the testing, diagnosis, commissioning and preventive triboactive, the cleaning of the lubrication systems of engines, fuel, cooling, and most importantly — the restoration of worn units repair-regenerative trains [5, 7–10, 12–14, 17]. In the last intake of the mineral particles of the catalytically active open friction surface are subjected to a mechanical cold deformation, are involved in adhesion, physical and chemical processes, tribromoimidazole, catalysis of tribo-processes [2, 15–17]. As a result of the repair coating [2, 5, 12, 15–17]. The serpentine triboactive create a durable anti-friction coatings [2, 15–17]. According to research by European and American researchers [15, 16], especially in Chinese state laboratory of Tribology of Tsinghua University [17], these minerals cause the formation of diamondlike carbon fi lms (Diamond-Like carbon fi lms — DLC-fi lms). Their surface is high purity and hardness, underneath are visible traces of mechanical processing, for 90 % consist of carbon, the resistance of 10–300 Ohm/cm. The eff ect of serpentine processing is manifested through the hours and ability to operate even without triboactive [2, 10]. Below are the laboratory tribotechnical tests of triboactive and fi ling of charges in the oil, which confi rm the eff ectiveness of non-traditional tribology.

Abstract:
The article presents information on the technological characteristics and industrial use of chroming electrolytes. The modern electrochemical technologies of repairing worn-out parts of agricultural machinery are considered. Particular attention is paid to the use of chrome plating methods making possible to increase the durability and reliability of the parts recovered in electrolytes of different composition, allowing to obtain coatings with high physical-mechanical properties that determine their suitability for the operation in the process of use for their intended purpose. The use of self-regulating dilute chroming electrolytes makes possible to increase the productivity of the deposition process of chromium coatings significantly, to obtain high-quality coatings of chromium and iron, and high adhesion to the base material - carbon, alloyed steels, and cast iron. The deposition of metals using reverse, pulsed currents with adjustable anodic-cathodic ratio of amplitude values and its duration allows to influence electro crystallization, control the structure, texture and roughness of the formed precipitate, which makes possible to get with predetermined functional physical and mechanical properties for specific repair conditions and subsequent operation in agricultural machinery. The following modes are recommended for brilliant coatings: when reverse current τ (cat) / τ (an) = 50-70, τ (cat) = 4-7 min, D(cat) = 40-100 А / dm2, D(cat) / D(an) = 3-4, Т = 60-65 ° С; when impulse current D(cat) = 40-100 А / dm2, Т = 60-65 ° С, τ (imp) = 1.5-2.5 min, τ (pauses) = 5-10 sec., impulse ratio 1.07-1.15.

Abstract:
Each agricultural producer is always faced with the problem of how long complex agricultural equipment should be used, when it will be the need to buy a new one, or in general, when the need is to switch to a new direction. Complex agricultural machinery is expensive, maintenance and re-pairs of it are expensive as well, and our market economy is unpredictable. The solution to this problem is considered on the example of winter wheat harvesting with a self-propelled fourth-class combine harvester. The following theoretical prerequisite for solving the abovementioned problem is proposed. An agricultural producer purchased a combine harvester for 5 million rubles, and then the costs associated with its operation are summed up over the years: for fuels and lubricants, wages for machine operators, costs for repair and maintenance of the combine, costs for spare parts, cultivation and grain harvesting, taxes, etc. After the fifth year of operation already, according to the in-structions, the combine harvester requires overhaul, and the costs of repair and maintenance are growing over time. The profit of an agricultural producer is formed as the difference between costs of the sale of grain. Over time, the productivity of the combine harvester decreases and at some point the operation of the combine becomes unprofitable; this is the point of obsolescence of the machine, when the agricultural producer must decide either to buy a new harvester or to change his business.
