    Maintaining a high level of reliability of service equipment in agricultural machinery repair facilities requires the use of modern methods and technologies for service. For their application, it is necessary to study the failures of equipment by causes of occurrence. This research paper justifies the need to create stocks of spare parts, assemblies and units and analyzes their influence on the availability coefficient of machines, i.e. economic feasibility.

    We examined a machine for depositing the water storage materials layer by layer while in subsoil soil. As a result of this activity, improve physical and chemical properties of the soil, and yields have tended to increase sustainable. The article justified basic technological parameters of the machine to achieve the best results. The inclusion of such a machine technology for growing crops tasked along with higher yields reduce the negative impact of the processes that lead to soil degradation.

    The basis of study of soils and water resources by future specialists in agroengineering in higher educational institutions is presented. Innovative pedagogical technology is developed according to the method of gradually increasing educational load, which follows from previously learned and mastered material. The acquisition of professional competencies for agroengineering will ensure the development of project activities on the basis of preservation and even multiplication of natural resources. In the training process of agroengineering development, it is important to develop the mathematical apparatus for the necessary calculations, which will ensure optimization of the parameters of technological processes and structures.

    At the present stage soil tillage is done mainly by applying the principles of mechanics. Its development is in three directions: improvement of the working bodies, increasing the productivity of agricultural machinery and power of tractors. All these directions lead to the accumulation of a wide variety of attachments, very large in size and mass of agricultural machines and tractors, which ultimately go to its limits. These features of the present-day stage are exhausted. It is necessary to look for other methods for tillage of the soil, using other principles of the physics or other areas of science.

    Производствените процеси в растениевъдството се осъществяват при взаимодействието между организационно свързани съвкупности от мобилни, стационарни и обслужващи единици. Ефективното използуване на скъпоструващата и високопроизводителна прибираща техника е пряко свързано със синхронизацията на работата им .

    В разработката е предложен математически модел за оптимизиране на взаимодействието между производсвените и обслужващите машини в съвместната им работа при прибиране на зърнено-житни култури.

    За оптимизация на съотношението между основните и обслужващи машини е използван критерият минимум на загубите от престои.
