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.

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.

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.

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.

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.

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.

Full textAbstract:
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.

The article presents the prospects of digitalization and use of artificial intelligence technologies in the technical modernization of the agro-industrial complex (AIC). In order to improve the efficiency of agricultural industry, including the productivity and quality of products in such sectors as crop production, livestock, processing of agricultural products, a transition to innovative technologies is required. Their use in agricultural production makes it possible to significantly competitiveness of the agricultural sector of the economy of the Russian Federation. To do this, the technical modernization of the agro-industrial complex, which provides for the renewal of its base with domestic agricultural machinery is required. In modern machines, a large number of electronic systems with various sensors are involved. They allow to control the operation of various units, including the internal combustion engine, transmission, work tools and other mechanisms. The use of such systems makes it possible to reduce the cost of maintenance and use of equipment, to monitor the modes of operation and technical condition of equipment around the clock, to conduct repair and maintenance activities as required. The current global trend is the use of remote machine diagnostics systems. They allow service centers and emergency support to diagnose a vehicle at a distance, reducing downtime. In recent years, there has been a trend towards digital solutions in machine maintenance. 3D technologies are promising for repair of agricultural machinery, including restoration and hardening of parts. They can be used to measure the geometric dimensions and determine the physical and mechanical properties of part faces of agricultural machines during the incoming inspection of spare parts and fault detection of parts, by scanning them. The introduction of digital technologies and artificial intelligence in the repair practice will reduce the duration of repair and maintenance actions during the technical service of agricultural machinery and significantly reduce the cost of their implementation.

The expansion of services and technological equipment applied to the agribusiness sector grows year after year, e.g., tractors and agricultural machinery, which use systems shipped with sophisticated software that collaborate to aid, and optimize activities in the field. Maintenance of agricultural machinery, including tractors, is routine in the life of any farmer, especially the preventive and corrective maintenance. In this paper, the objective was to evaluate an alternative for the use of diagnostic software in the prediction of failures that may occur in the tractor clutch system. In this study, the PicoScope6 software was used to identify the failures in this system, and then, using the predictive maintenance phase, was compared with classic maintenance methods, allowed for estimating the necessary repair time. Results showed that software identified more precisely the mechanical components that presented failures. From the identification of failure components, a list of repairs and exchanges was estimated, and, when compared to the list of components generated by inspection without diagnostic software, the repair time was reduced by 88%, and the cost of repair in up to 93%. The availability of the equipment also increased as a result of the shorter repair time, thus maximizing the machine time in the field.

To ensure highly efficient operation of agricultural machinery and equipment, it is necessary to improve the system of technical services in agriculture by creating specialized service centers. The system of maintenance in agriculture is characterized by a significant decrease in efficiency due to critical physical and moral wear of equipment of repair and technical enterprises (RTP), low level and insufficient qualification of Executive personnel and managers of enterprises of the agro-industrial complex (AIC). These changes led to the loss of the majority of RTP for agriculture and their re-equipment for non-agricultural production. According to experts, in the service sectors of agriculture, there was a loss of technological production and a significant part of applied science. This is especially worrisome due to the catastrophic aging of cars and the lack of funds to replace them. It is necessary to improve the General condition of the equipment of repair shops, the availability of existing agricultural enterprises with production areas is no more than 50%, technological equipment — no more than 47%, and technological equipment and equipment of workplaces — 15% — 40%, respectively. The priority areas of modernization of the infrastructure of technical service of agricultural machinery are related to updating the technological base of machine repair. Based on a reliable assessment and analysis of the technological level of RTP, which takes into account a number of technological, technical, organizational and environmental factors of production. RTP does not have the necessary equipment and devices to perform a number of maintenance and maintenance operations. The process of developing the technical service infrastructure lags far behind the level of structural and technological complexity of agricultural machinery. Due to technological requirements, such complex components and assemblies as engines, hydraulic equipment, fuel pumps of domestic and imported agricultural machinery should not be repaired in the conditions of farms. In a number of works proved the following provision: evaluation of the technological level repair enterprises shall be based on the application of such methods and means of technological preparation of production, which correspond to the advanced achievements of science and technology, and provide high-capacity system maintenance to continuous improvement. A high technological level of technical service enterprises is a condition for efficient operation of any type of production, ensuring its stability and reliability of operation, flexibility and adaptability, high intensity and waste-free operation.

This paper focuses on challenges of prison farm management in Nigeria. The empirical results are based on a qualitative and quantitative survey of 54 inmates and 17 prison officers in Ibite-Olo and Ozalla prison farms in Enugu and Edo States of Nigeria respectively. The findings show that the prison farms under study had collaboration with partner agencies such as the federal ministry of agriculture (57.9%), agricultural extension agents (47.4%), agricultural research institutes (42.1%) and NGOs (36.8%), among others. The necessary support from partner agencies covered the following: financial aid (78.9%) and sales/maintenance of farm machinery and implements (68.4%). Furthermore, inmates and prison officers stated the challenges hindering effective running of prison farms’ agricultural activities, including: inadequate funding, lack of physical infrastructure, inadequate farm equipment and poor storage facilities. The findings support the conclusion that the Nigerian Prison Service should make an upward review in its budgetary allocation to prison farms to enhance service delivery and inmate reformation, alongside provision of adequate infrastructure, equipment and farm inputs.

The share of the main types of agricultural machinery with a service life of more than 10 years in the total volume of equipment remains high. The maintenance the performance of machinery and equipment are performed mainly by repair and restoration processes. In recent years, there used a 3D-scanning technology in the repair of machines. (Research purpose) The research purpose is in searching for the possibility of using 3D-scanning technologies in the repair of equipment based on the analysis of information materials. (Materials and methods) Authors used open information sources from various scientific and educational organizations for analysis. The great attention has been paid to the analysis of 3D-scanning technologies presented at various international specialized exhibitions. It was found that various laser scanners have been developed and used for 3D-scanning, mainly for quality control of parts manufacturing. It was also found that they can be used to control the geometric, physical and mechanical parameters of agricultural machinery parts during the input control of spare parts and repair of machines. (Results and discussion) It has been found that 3D-scanning improves the accuracy and performance of measurements in comparison with contact devices. The article notes that the use of 3D-scanning in convergent modeling technologies and in additive manufacturing is becoming a modern trend in mechanical engineering. (Conclusions) A promising direction for the introduction of 3D-technologies in repair production is the integrated use of additive technologies and 3D-scanning; when parts are defective after disassembly of the repaired units, the machine uses a 3D-scanner to determine the wear, and a 3D-printer to restore the worn surface, taking into account the uneven wear. The advantages of this repair technology include increasing the accuracy of measurement, reducing the range of measurement tools used, and the ability to restore parts of complex geometric shapes. Spot application of a layer of additive material to the wear site reduces material consumption by 20-90 percent.

ABSTRACT In the mechanical harvesting of sugarcane, a self-propelled harvester is used in conjunction with an agricultural implement named infield wagon, which has the function of storing and transporting the harvested product. Much of the cost of sugarcane production comes from this operation (30 to 60%). Among the operational costs of agricultural machinery, the cost of repair and maintenance (CRM) is relevant. Therefore, the objective of this study was to determine the parameters of the CRM mathematical model based on the life (hours of use) for the infield wagon, using the method of the American Society of Agricultural and Biological Engineers (ASABE). These CRM models were obtained for two sets of infield wagon from different manufacturers and their costs over up to 12 years. The model was adjusted and then validated using descriptive statistics methods. Fitted CRM equations were different for each analyzed set of infield wagon and, therefore, are a valuable tool in the management of mechanization in sugarcane mills as it provides elements that can support decision-making of managers in the acquisition and management of agricultural implements.

In the course of operation of transport and technological machines (tractors, cars, grain and forage harvesters and other complex agricultural machinery), the joints in the nodes, aggregates, and mechanisms are worn out. The amount of wear depends on the service life and operating conditions. (Research purpose) The research purpose is in searching for the most acceptable method for practical application of determining the optimal frequency of technical service to ensure high reliability and efficiency through reducing the intensity of wear of the interfaces of components, aggregates, mechanisms of the transport and technological machine; proposing coefficients for adjusting the frequency standards when planning and organizing maintenance and repair of agricultural machinery. (Materials and methods) The condition of the crankshafts of internal combustion engines at the operating time close to carrying out major repairs, 5000 hours (maintenance - 3) for tractors, 192,000 km and 150,000 km (routine repairs) for vehicles like KAMAZ and GAZ-3309. Authors applied the methods used to determine the optimal frequency of maintenance and repair, which characterize the quality of technical impacts. (Results and discussion) The article presents calculations performed to determine the maximum performance of the unit as part of a tractor with different maintenance intervals and an agricultural machine based on the use of a statistical method (according to the probability of failure). Authors found that the most acceptable method for determining the optimal frequency of technical impacts is the "unit cost" method. The article proposes coefficients for adjusting the frequency of technical impacts. (Conclusions) Determining the optimal frequency of technical impacts will minimize operating costs and prevent possible failures. To do this, it is necessary to choose an acceptable method that determines the optimal frequency and ensures minimal wear of the interfaces in the nodes, aggregates, mechanisms of transport and technological machines.

Full textAbstract:
Intensive use of agricultural production technologies has recognized the intensive characteristics of agricultural producers, which allowed to present the need for frequent diagnostics, maintenance and repair. This transition is due to objective trends in the development of agricultural machinery. The solution to this problem involves the development and creation of effective tools for monitoring and diagnosing the state of the transmission elements of agricultural machinery; assessment of the value of the residual life of individual elements of the system and the study of energy conversion processes in these elements; construction of mathematical models on the basis of which it is possible to predict the occurrence of dangerous damage depending on the operating conditions of the equipment. Diagnostic means must ensure the assessment of the condition of the working surfaces of the interacting transmission elements, control of wear of their surfaces and assessment of the performance of the unit as a whole or the kinematic pair without their disassembly during operation. The time of collection of diagnostic information and allocation of informative signs and parameters of signals should be minimized. Control methods should be as simple as possible, and the means that implement them - compact, with built-in algorithms for information processing and decision-making. The most informative parameter that carries the maximum information about the state of the unit of a working machine or unit is mechanical oscillations (vibrations) - elastic waves propagating in continuous media. Measurement of vibroacoustic characteristics on bearing supports of mechanisms allows to recognize such defects and damages as imbalance and skew of shafts; damage to plain and rolling bearings; damage to gears in gears; damage to couplings; damage to electrical machines. With the systematic use of modern diagnostic methods it is possible to avoid serious damage to the transmission elements and reduce operating costs for maintenance of agricultural machinery due to the fact that the repair is carried out only when the measurement results indicate its need.

The article presents the results of research and analytical reviews to determine the possibilities of using digital technologies in the disposal of decommissioned agricultural equipment. The rationale for the use of digital technology in the formation of a resource-saving eco-friendly system for the disposal of agricultural machinery. Until recently, technical support for equipment manufacturers ended with the operation phase. The requirements of regulatory documents on the need to dispose of decommissioned equipment in design, operational and repair regulatory documents were purely declarative in nature and have not been (and are not yet implemented in Russia) by its manufacturers. he use of CALS (IPI) — technologies for the formation of a system for utilization of agricultural machinery will create a common database that will be based on the fi nal state of parts and their variable properties. Also, their application will make it possible to provide logistic support for all components of the material fl ows of equipment throughout the life cycle. In addition, the use of common software aimed at performing these functions will create the necessary conditions for the operation and maintenance of the functionality of the system. The most optimal option is to create VET utilization systems taking into account the national peculiarities of Russia on the basis of existing foreign developments both for creating operational and repair documents in digital format, and for developing technologies for utilization of equipment that take into account the requirements of resource conservation and the environment.

The optimization machinery model was developed to aid decision-makers and farm machinery managers in determining the optimal number of tractors, scheduling the agricultural operation and minimizing machinery total costs. For purpose of model verification, validation and application input data was collected from primary & secondary sources from Elsuki agricultural scheme for two seasons namely 2011-2012 and 2013-2014. Model verification was made by comparing the numbers of tractors of Elsuki agricultural scheme for season 2011-2012 with those estimated by the model. The model succeeded in reducing the number of tractors and operation total cost by 23%. The effect of optimization model on elements of direct cost saving indicated that the highest cost saving is reached with depreciation, repair and maintenance (23%) and the minimum cost saving is attained with fuel cost (22%). Sensitivity analysis in terms of change in model input for each of cultivated area and total costs of operations showing that: Increasing the operation total cost by 10% decreased the total number of tractors after optimization by 23% and total cost of operations was also decreased by 23%. Increasing the cultivated area by 10%, decreased the total number of tractors after optimization by(12%) and total cost of operations was also decreased by 12% (16669206 SDG(1111280 $) to 14636376 SDG(975758 $)). For the case of multiple input effect of the area and operation total cost resulted in decrease maximum number of tractors by 12%, and the total cost of operations also decreased by 12%. It is recommended to apply the optimization model as pre-requisite for improving machinery management during implementation of machinery scheduling.

Reducing the maintenance man-hour is one of the ways to improve of operation efficiency of agricultural machines. The total maintenance time of the agricultural machine is determined by the critical path and other network planning parameters. The network model in the form of network diagrams is used for visualization and analysis of maintenance processes. Building network diagrams be not a trivial task and it takes a long time to build. Therefore, automating the creation of network diagrams of technological maintenance of agricultural machines is an urgent task. This work aims to develop an algorithm for creating and analyzing network diagrams for planning the processes of technological maintenance and repair of various agricultural machines. When building an algorithm for creating network diagrams, the methodological apparatus of network planning and basic algorithmic structures were used. The algorithm is realized in the Matlab programming language. The article presents the flowchart and a description of the formation of an array of all and full paths. The description of identifying fictitious operations in the network diagram is given. The present algorithm calculates the maintenance man-hour of paths, determines the critical path of the network diagram and visualizes it on the graph, and also calculates the time reserves of the specified work. The logic of the algorithm is developed in accordance with the rules for building network models and excludes dead-end and tail events, closed loops. Thus, the algorithm will increase the efficiency of solving practical tasks of network planning of maintenance of agricultural machinery, shorten working hours and time for the building of the network diagram and reduce the associated possible errors.

The technological potential of agricultural enterprise is complex system consisting of various elements with different functional capabilities and features, which are characterized by the characteristics of complex systems. The complexity of technological potential lies in the presence in structure of its several elements - technological preparation of production, equipment and technology. There is no doubt that the basis of technological potential is an active part of main production assets, namely the equipment park. Working machines and equipment, instrumentation, transmission devices and tooling - this is exactly what primarily determines the level of labour productivity. The aim of the study is to develop recommendations for efficient use of machinery of agrarian enterprises as part of their technological potential, to solve important task of developing them and improving quality and competitiveness of their products. In methodological basis of this research various methods were used: an analytical method, abstract and logical method, system approach, statistical and economic analysis, method of analogies, and method of comparative and expert estimates. The study showed that in order to increase the efficiency of use of technical equipment and more fully satisfy agricultural producers in technical services, it is necessary to create the technical centre for maintenance and repair of agricultural machines. As result, implementation of preventive strategy of technical maintenance and repair of equipment will reduce the number of machine failures by 2 - 2.5 times, increase the use of resource of their components and mechanisms by 30%, and significantly reduce the loss of agricultural products due to long downtime of mechanization equipment and crop shortages while increasing agro-technical timelines for field work.

Mechanization of labor on small farms and individual farms is a very important issue of modern agriculture. The use of small agricultural machinery with a capacity of up to 16 kW is quite relevant today. Small-sized machinery is divided into: small 4-wheeled tractors, 2-wheeled motoblocks, cultivators, machines and equipment. With the help of this technique perform various agricultural and other types of work in crop production, horticulture, gardening on small plots, livestock and more. Despite its rather small size, small equipment also has various mechanisms that fail over time. Most often, the parts of the internal combustion engine fail. In general, the cost of repairing the internal combustion engine during operation may exceed the total cost of the engine by 5-6 times. Thus, there is a question of improving the system of technical service of engines of small tractors. This article considers the issue of increasing the efficiency of operation of internal combustion engines for small tractors, due to the effective conduct of after-sales or post-repair running-in and improving the maintenance system. Types of small-sized equipment are presented. The analysis of possible loading and speed modes of cold and hot running-in of internal combustion engines and means for their realization is carried out. Technical means for running-in and testing of internal combustion engines are analyzed. The following formulas are given for determination: smoke of exhaust gases at running-in of engines; light transmission of exhaust gases; speed control range; load torque; the content of harmful substances (Q) in the exhaust gases on the j-th components. The necessity of bench running-in of engines of small-sized agricultural machinery is substantiated. The functional scheme of the stand for running-in and testing of internal combustion engines is considered. The stages of cold and hot running-in of small-sized engines are described. With the help of the received information, the results are made and the analysis of methods of running-in of internal combustion engines of small-sized agricultural machinery is carried out.

В статье проанализированы наиболее существенные факторы, влияющие на техническую готовность тракторов к работе, с помощью математико-статистического моделирования. Исследование проведено на одном из сельскохозяйственных предприятий Ярославской области. Техническая готовность техники зависит от множества субъективных и объективных факторов. В результате исследований авторами было выявлено восемь факторов, влияющих на техническую готовность тракторов (затраты на ремонт и техническое обслуживание (ТО) одного физического трактора за год, руб.; затраты на ТО на один эт. га в год, руб.; стоимость материально-технической базы (МТБ) по ремонту и ТО, приходящаяся на один эт. трактор, тыс. руб.; обеспеченность работающими механизаторами на 100 физических тракторов, чел.; наличие механизаторов, имеющих 1–3 классы квалификации, % к общему количеству; доля услуг предприятий сельхозтехники в затратах на ремонт и ТО, %; затраты на запасные части за один год на один эт. трактор, руб.; доля стоимости узлов и агрегатов при ремонте тракторов, %). Для описания процесса были использованы методы многофакторного корреляционного и регрессионного анализа. Выявлено, что наиболее существенное влияние на результативный признак (коэффициент технической готовности тракторов) оказывает величина затрат на ТО в расчёте на один эт. га в год и наличие механизаторов, имеющих 1–3 классы квалификации. Применение предложенной методики, по мнению авторов, обеспечит не только определение технического состояния агрегатов и механизмов, но и сократит время простоя техники, снизит затраты на ТО и технический ремонт, а также на расход запасных деталей и материалов и повысит производительность труда. The article analyzes the most significant factors affecting the technical readiness of tractors for work using mathematical and statistical modeling. The research was carried out at one of the agricultural enterprises of the Yaroslavl region. Technical readiness of machinery depends on many subjective and objective factors. As a result of the research the authors identified eight factors affecting the technical readiness of tractors (repair and maintenance costs (maintenance) of one physical tractor per year, Rub.; maintenance costs per reference unit ha per year, Rub.; the cost of the material and technical base (MTB) for repair and maintenance which is accounted for by reference tractor, RUB, in thousands; provision of working machine operators for 100 physical tractors, people; the presence of machine operators with 1–3 qualification classes, % of the total number; share of agricultural equipment services in repair and maintenance costs, %; service parts costs per year per reference tractor, Rub..; share of components and assemblies cost during tractor repair, %). Multifactor correlation and regression analysis techniques were used to describe the process. It was revealed that the most significant impact on the effective feature (tractor technical readiness factor) is the amount of maintenance costs calculated per reference ha per year and the presence of machine operators with 1–3 qualification classes. The application of the proposed technique according to the authors, will ensure not only the determination of the technical condition of units and mechanisms, but also reduce the out-of-service time of equipment, reduce maintenance and technical repair costs, as well as the consumption of spare parts and materials and increase labor productivity.

The accelerated development of technical service is a natural manifestation of a common strategy of modern industrial production. Scientific research and practice indicate that the need for machines in maintenance and repair is an objective reality. This features of modern techniques, the conditions for its operation. The importance of development and improvement of repair and service production is to provide resource saving agricultural machinery. With a continued trend towards ensuring the equalization of components of the technical product, it is mainly used in the principle of replacing or restoring elements during operation. The article describes the technical operation of the machine and tractor fleet. It is noted that for the full functioning of the technique it is necessary to diagnose in a timely manner, then the need is running and running on the need. If you compare the overall generation of tractors in conditional hectares and planning funds to pay for labor, it is necessary to proceed from the costs of time costs for the conditional hectare of tractor-transport work, taking into account. Using the indicator of normosmen, we can comprehensively assess the effectiveness of the use of techniques for information for intra-economic planning and managing the work of the machine-tractor fleet.

PurposeThe after-sale service industry is estimated to contribute over 8 percent to the US GDP. For use in this considerably large service management industry, this article provides verification in the application of decision tree-based machine learning algorithms for optimal maintenance decision-making. The motivation for this research arose from discussions held with a large agricultural equipment manufacturing company interested in increasing the uptime of their expensive machinery and in helping their dealer network.Design/methodology/approachWe propose a general strategy for the design of predictive maintenance systems using machine learning techniques. Then, we present a case study where multiple machine learning algorithms are applied to a particular example situation for an illustration of the proposed strategy and evaluation of its performance.FindingsWe found progressive improvements using such machine learning techniques in terms of accuracy in predictions of failure, demonstrating that the proposed strategy is successful.Research limitations/implicationsThis approach is scalable to a wide variety of applications to aid in failure prediction. These approaches are generalizable to many systems irrespective of the underlying physics. Even though we focus on decision tree-based machine learning techniques in this study, the general design strategy proposed can be used with all other supervised learning techniques like neural networks, boosting algorithms, support vector machines, and statistical methods.Practical implicationsThis approach is applicable to many different types of systems that require maintenance and repair decision-making. A case is provided for a cloud data storage provider. The methods described in the case can be used in any number of systems and industrial applications, making this a very scalable case for industry practitioners. This scalability is possible as the machine learning techniques learn the correspondence between machine conditions and outcome state irrespective of the underlying physics governing the systems.Social implicationsSustainable systems and operations require allocating and utilizing resources efficiently and effectively. This approach can help asset managers decide how to sustainably allocate resources by increasing uptime and utilization for expensive equipment.Originality/valueThis is a novel application and case study for decision tree-based machine learning that will aid researchers in developing tools and techniques in this area as well as those working in the artificial intelligence and service management space.

With prolonged use of machines, wear of parts is accompanied by a decrease in performance indicators, causing a deterioration in the quality of products. The power take-off shaft experiences significant static and dynamic loads. The high wear rate of the power take-off shaft is due to constant friction with the clutch disc, gears, and bearing inner rings. The manufacture of a new power take-off shaft requires significant costs, so the development of new technological processes for repair and restoration is urgent. A promising direction of restoration technology in the organizational plan of deepening the method of group restoration technology is the creation of unified-group equipment for surface restoration. It has been established that most of the parts of remanufactured machines are rejected due to slight wear of the working surfaces, making up no more than 1% of the initial mass of parts. As experience and practice show, on the one hand, it is technically impossible to avoid the repair of agricultural machinery, and on the other, it is economically feasible. After all, most of the worn out parts have a high residual value: during their restoration, 20-30 times less metal and materials are consumed than in the manufacture of new ones. The following problems are considered: the choice of the technological process of restoration, the choice of technological equipment, tools. Restoration of details is a technically justified, economically justified measure. This allows repair shops to reduce downtime of faulty machines, improve the quality of maintenance and repair to positively affect the reliability of the use of machines. To restore the efficiency of worn parts requires 5-8 times less technological operations compared to the manufacture of new ones [1, 2]. Restoration of parts allows you to get a considerable economic effect, as much lower consumption of metal and auxiliary materials, and the cost of the restored part is 60-80% of the cost of new ones. Therefore, to make this recovery process effective, it is necessary to introduce new processing and recovery methods, as well as to improve existing equipment. The production of a new power take-off shaft requires significant costs, and the detection of new technological processes of repair and restoration is relevant.

"Optimizing Nitrogen and Residue Management to Reduce GHG Emissions while Maintaining Crop Yield: A Case Study in a Mono-Cropping System of Northeast China."

Full textAbstract:
Reducing the use of nitrogen fertilizers and returning straw to field are being promoted in northeast China (NEC). In this paper, the agricultural production system model (APSIM) was applied to assess the long-term variations of crop yield and soil GHG emissions in a maize mono-cropping system of NEC, and the simulation results were combined with lifecycle assessment to estimate annual GHG emissions (GHGL) and GHG emission intensity (GHGI, GHG emissions per unit yield) of different agricultural practices. Under current farmers’ practice, emissions due to machinery input (including production, transportation, repair, and maintenance) and soil organic carbon (SOC) decline accounted for 15% of GHGL, while emissions from nitrogen fertilizer input (production and transportation) and direct N2O emissions from soil accounted for the majority (~60% of GHGL). Current farmers’ practice in terms of N application and residue management are nearly optimal for crop production but not for climate change mitigation. Reducing N input by 13% and increasing straw retention by 20% can maintain crop yield and SOC, and also reduce GHGL and GHGI by 13% and 11%, respectively. However, it is not feasible to incorporate the straw used as household fuel into soil, which could incur substantial fossil CO2 emissions of 3.98 Mg CO2-eq ha−1 resulting from the substitution of coal for straw. APSIM was successful in simulating crop yield, N2O emissions, and SOC change in NEC, and our results highlight opportunities to further optimize management strategies (especially for the nitrogen and straw management) to reduce GHG emissions while maintaining crop yield.

Full textAbstract:
The presence of foreign firms in a region can create spillovers to other firms, both within the intra-industries (industries itself) and inter-industries (other industries). Spillover from foreign firms can be in the form of technology transfer, efficiency improvement, managerial knowledge which ultimately is expected to increase productivity for other firms not only in large enterprises but also for micro small and medium enterprises (MSMEs). Hence, this paper aims to identify the potential backward spillover of foreign firms to MSMEs in East Java and the individual results show that the four highest backward spillovers values of foreign industries are industry of components and spare parts of the prime mover motor, industry of agricultural and forestry machinery and services for supporting, maintenance and repair, industry of pump and compressor and industry of measurement tools, manual regulator and testing. All of them are respectively located in Surabaya City, Pasuruan District, Pasuruan District and Mojekerto District. Furthermore, the general results show that the potential backward spillover exists in rubber, rubber goods and plastic goods industries as well as chemicals and goods from chemical material industries. The foreign firms which have highest backward spillovers are located in Pasuruan District, Mojekerto District, Sidoarjo District, Surabaya City and Gresik District. Therefore, the provincial government of East Java should immediately prepare and support both technically and financially to MSMEs in providing raw materials required by foreign firms based on the industrial classification and location results of this study. In addition, the provincial government of East Java can coordinate with the district governments in the areas of those foreign firms for preparing MSMEs in supplying raw materials.

Full textAbstract:
The article draws on the 1950s-1960s archival documents from the Russian State Archive of Contemporary History and from the State Archive of Contemporary History of the Lipetsk Region to study the early days of the Khrushchev agrarian reform implementation: reorganization of machine and tractor stations (MTS) and formation of new production infrastructure in the kolkhozes. The main emphasis is put on studying financial preparedness of kolkhozes to purchase tractors, combine harvesters, and other agricultural machinery for machine and tractor stations and to create material and technical base for their maintenance, operation, and repair. The archival data allows the author to conclude that kolkhozes in most republics, territories, and regions of the RSFSR (with exception the Krasnodar, Stavropol, and Rostov regions) did not have the financial means to purchase the complex equipment. The reform of 1958 was mandatory for all regions without exception. The article presents the party regional committees’ calculations on the financial situation of kolkhozes. In the Perm region only 13 kolkhozes out of 1167 (1.1%) had means to buy the MTS equipment. In many areas of the Center, the Volga region, the Urals and Siberia, kolkhozes took a wait-and-see position. In the Altai territory, only 200 kolkhozess out of 697 (28.7%) expressed a desire to buy equipment, in the Moscow region — 300 out of 1126 (26.6%), in the Smolensk region — 113 out of 955 (11.8%), in the Kalinin region— 108 out of 2350 (4.6%). The paper shows the method used to overcome the resistance kolkhozes to the reform: a powerful party propaganda campaign via organizing meetings proved very effective. The reform of 1958 was designed to offer new prospects and incentives for kolkhozes’ development. The study reports some contrarius information: in many areas of the country, kolkhozes and newly formed repair and technical stations (RTS) flailed under new conditions. During the reform in the Leningrad region there were formed 25 RTS with 5 branches and 10 specialized stations. After a year of work only 3 RTS managed to break even. Regional leaders obtained government consent to create sovkhozes on the basis of the RTS and adjacent kolkhozes. The reform of 1958 is characterized as another attempt to transfer funds from kolkhozes to state budget. It worsened financial and economic indicators of most kolkhozes.

Full textAbstract:
In agriculture, a large number of different lubricating and cooling liquids are used in the operation, maintenance and repair of agricultural machinery. In the process of use, technical fluids become contaminated with foreign impurities and require periodic cleaning. Magnetic sedimentation tanks are well suited for this. The studies were carried out in order to determine the parameters (the magnitude and gradient of the magnetic field strength, the height of the apparatus, the concentration of particles), at which coagulation of particles is observed in a non-uniform magnetic settler. The experiments were carried out on a laboratory setup for studying coagulation in the working area of a magnetic sump. For a given magnetic system, the geometric dimensions of the apparatus were determined in such a way that the magnetic field acts in the entire working volume of the sump and effectively traps foreign metal impurities. The value of the magnetic induction of the field B is proportional to the square of the distance from the investigated point to the pole of the electromagnet Н0. At a distance of 300 mm and further, the magnetic force has almost no effect on the particle, so the height of the sump should be less. The lowest magnetic induction is observed in the middle of the coil. A decrease in the current in the winding entails a reduction in the length of the floccule; magnetic coagulation takes place when the concentration of particles in the coolant is more than 0.3 g/l, with a lower content, it is not observed due to significant distances between the particles; the effect of coagulation is noted in the entire area of action of the magnetic field, while the length of the floccules decreases with a decrease in concentration. The distance at which the effect of coagulation between particles is observed is determined by a complex function that depends on the current in the winding, the field strength, their distance from the pole of the electromagnet, and also on the size of the particles.

Full textAbstract:
Repair and maintenance cost is considered as one of important items for machinery management and selection especially agricultural tractors. The present study was carried out in Dongola area for tractor repair and maintenance costs estimation. The data was collected from records of Elshimalya Company for Agricultural services. Forty-four tractors representing two powers sizes, 75hp and 150hp used in the area were selected for this study. Based on the data collected, regression correlation analysis was carried out and mathematical models were derived to predict the accumulated repair and maintenance (R and M) costs as percent of purchase price in relation to accumulated hours of use and age (years) for each tractor size, and for the two sizes collectively. Five model forms (linear, logarithmic, polynomial, power and exponential) were derived and the power function was found the best fit to explain the relation. The accumulated Rand M costs as percent of purchase price (Y) was increased as the accumulated hours of use (x) and age (g) of the tractor in years were increased. A high correlation was found between the accumulated R and M cost and both accumulated hours of use and tractor age in years (Average R2 = 0.93).
It was concluded that the power function was the best fit for repair and maintenance cost estimations and this relation may be used as an average of the two tractor powers, for estimation of the accumulated R and M costs as percent of purchase price (Y) with accumulated hours of use (x) and age (g): Y=0.028x0.662 (mean) Y=12.294g1.276 (mean).
