This article discusses issues related to the scientific and methodological problems of the acceptance of the machines for repair and their solutions. The production process of machinery repair is a set of human actions and manufacturing instruments, performing in a certain sequence and providing recovery, serviceability and full (or near full) resource products. It consists of a series of technological processes. External cleaning, washing and inspection repair is among the most important technological reconditioning processes. During the period of Russia's regional associations and specialized departments "Agricultural machinery" all tractors, automobiles, appliances and machines when accepting in the overhaul or issuing from it had to met the "technical specifications for delivery in overhaul and the issuance from the overhaul of tractors and self-propelled chassis, engines, their units and assemblies" (TU 70-260-71). The machine must be complete. At present, the institutional conditions of delivery vehicles and other mechanisms for repair in the technical service has changed substantially. However, technical requirements cannot and should not be significant changed, since the conditions of vehicles operating mechanism and require the highest quality as the machine as a whole and its parts. The article considers the basic requirements and ways to optimize the process of acceptance in the repair of vehicles through the example of special-purpose vehicles as part of their technical service.

The assessment of the suitability of the granulometric composition of the crushed stone aggregates (CSA) for an unbound base and subbase layers of pavement, in the Republic of Serbia is done based on the defined gradation bands, uniformity degree (Cu), coefficient of curvature (Cz), percentage of fines and percentage of particles passing a 0.02 mm sieve. On the other hand, standards which define the quality requirements of aggregates and unbound mixtures for road construction SRPS EN 13242 and SRPS EN 13285 introduce a significantly different approach to the assessment of the granulometric composition suitability. Categories are defined. Each category includes a particular boundary band, tolerances on sieves, differences in values passing each sieve. The categories are defined depending on the field of the application. For seven CSA 0/31.5 mm used for the construction of Corridor XI, a comparative analysis of the granulometric composition suitability was performed according to the requirements of the existing Technical Specifications (TS) of PE "Roads of Serbia" (PERS) and the specified SRPS EN standards. The analysed curves satisfy those technical requirements, but vary in categories from the most severe mixtures of the normal granulometric composition of the GA category, to the open mixtures of the GP category. It was concluded that the principle based on the defining allowed tolerances on the sieves and between the sieves, is more suitable for field control of of the granulometric composition and the good granularity of the aggregates. Technical Specifications should be modified to this approach.

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.

HighlightsHorizontal distribution according ISO Standard 16119 is a measurement procedure to evaluate boom sprayers.ISO Standards 5682-1 and 5682-2 establish technical requirements for horizontal patternators.In this study, three types of patternators were evaluated to test their capability to meet the standards.The evaluated patternators showed similar results for spray distribution patterns.Minor deviations from ISO Standard 5682 did not imply differences according ISO Standard 16119.Abstract. Uniformity of spray volume distribution is one of the officially established measurements for the evaluation of horizontal boom sprayers according to ISO Standard 16119 and requirements established by ISO Standard 16122. Measurement of spray distribution patterns requires the use of specific devices such as horizontal patternators, which are included in the technical specifications for ISO Standards 5682-1 and 5682-2. Three such devices were tested, including two manual patternators (fixed and mobile) and one electronic patternator. According to information provided by the manufacturers, all three patternators align with ISO requirements. This study evaluated and compared the results obtained with the three patternators. Specifically, the horizontal distributions measured by the patternators were evaluated and compared using four nozzle types (XR 11003, AIXR 11003, TTJ60 11003, and AITTJ60 11003), three boom heights, and three operating pressures. Tests were conducted to quantify single-nozzle spray patterns, the coefficient of variation (CV) of the entire boom distribution, the liquid recovery capability of the three patternators, and the ability to simulate the entire boom spray distribution from a single-nozzle spray pattern. Results demonstrated correct functioning of all three patternators, resulting in identical conclusions considering the requirements established in the ISO standards. The CV values of the horizontal distributions were less than 10% for all cases. Moreover, the trends in values for all the evaluated factors (nozzle type, boom height, and operating pressure) were the same, independent of the patternator used.
