One of the main ways to improve the efficiency of agricultural machinery operation is to study technical readiness when planning the main stages, objects and scope of maintenance and repair work. Existing systems of maintenance and repair of machinery do not fully take into account the operating conditions characterized by a certain group of factors. The problems of an individual approach to assessing the technical condition and promptly adjusting the modes of maintenance and repair of machines in the conditions of their operation remain relevant. The purpose of this article is to study the impact of operational factors on the technical condition of agricultural machinery in the process of its use. For example, the object of research is the means for preparing and distributing feed (MPF) used in animal husbandry. The paper applies the method of a priori ranking and the methodology for assessing the non-randomness of expert agreement. A classification of operating conditions is presented, taking into account their influence on changes in the technical condition of the feeding and dispensing equipment. From the set of presented conditions, the factors affecting the operation of air defense systems are identified. Based on the results of the expert survey, data were collected for a preliminary ranking of the factors. For each factor, the sum of the ranks of all experts was determined. Four factors were identified that have a predominant influence on the technical condition of air defense systems: reliability of the vehicle design; professionally important qualities of personnel; organizational and technological factors; intensity of operation and load on operating equipment. The concordance coefficient was used to estimate the degree of agreement among experts' opinions. The results obtained by a priori ranking can be considered satisfactory and adequate. The test of the hypothesis of non-randomness of the experts' agreement according to the Pearson criterion indicates the significance of the concordance coefficient, significant similarity and non-randomness. The results of the study of the influence of operational factors on the technical condition of air defense systems have been practically confirmed and used in production conditions.

An important component for ensuring the efficient use and improving the reliability of agricultural machinery is the availability of appropriate regulatory and technical documentation governing the requirements for its technical condition and operation. Serviceability of equipment can be restored during repair, and operability - is maintained during maintenance and in the course of operation on the basis of recommendations provided by the instructions and guiding materials on the use of machines. For timely and effective maintenance and repair of means for preparation and distribution of fodder (MPDF) it is necessary to know: criteria of operability loss; limit and admissible values of parameters of the technical state; process indicators of transition of machinery from operable to non-operable state; regularities of changes in the main properties. The article presents the monitoring of instructions for maintenance and operation of machinery, guiding materials for use from the position of their informativeness on the implementation of reliability requirements. The monitoring was conducted for the analysis of foreign samples of MPDF. Within the framework of the monitoring, grinding-mixing mechanisms (GMM) were analyzed from the position of availability of information about design features, possible failures and malfunctions, main ways of restoration of serviceability. The main provisions, which are determinative for estimation of technical condition of separate parts and working bodies, for improvement of GMM and MPDF reliability as a whole when using guiding materials, have been established. The provisions include: information about indicators of machine reliability; frequency of maintenance and repair of machines, restoration of working parts; information about the labor intensity of maintenance and repair of machines, restoration of working parts; diagrams of assembly-disassembly of mechanisms, restoration of working parts; typical failures and sequence of their elimination; criteria of limiting condition; technologies of restoration of working parts; information on storage requirements
