The closed method of storing agricultural machinery is more effective than the open one, but it is also the most expensive. In this way, garages, hangars, sheds etc. are used and at the same time it takes into consideration only the area, not the volume. In this article we solved the problem of using the volume of the room where the equipment is stored. It is proposed to place equipment on three levels. The first level is the floor, where it is advisable to place power equipment. The second level includes agricultural machinery -cultivators, seeders, plant protection machines, etc. It is formed from L-shaped platforms, controlled by four-link mechanisms attached to the facade wall. Four-link mechanisms carry out lifting of agricultural machines fixed on L-shaped platforms. Electric winches serve as the driving mechanism. Spontaneous lowering of the L-shaped platforms is excluded due to the stops that are installed under the platforms. At the third level we can hang smallsized equipment and containers with spare parts for machines by the brackets attached to the front wall. Suspension is carried out by means of a crane beam. By applying a modernized hook we can solve the problem of disconnecting and connecting the lifting hook with the ring on the load (small-sized equipment, containers). Modernized hook is equipped with a rotation mechanism around the vertical axis and a branch pipe in the form of a ring. There are nozzles on the ring. Compressed air is supplied to the branch pipe and, accordingly, to the nozzles. The hook is rotated in the right direction and deviated in the direction of the ring on the load by means of the console. The use of the modernized hook of the lifting device allows it to be connected and disconnected with the ring on the load at a distance inaccessible to the operator. Technical and economic efficiency is ensured by placing a larger number of machines in the room with closed storage.

The paper attempts to analyze the role and importance of law in the development of the digital economy, as well as enforcement and incentive measures. This is a descriptive study, and an overview of the most important normative acts regulating the development of the digital economy in Russia is given. Various aspects of the reverse impact of the digital economy on the law itself are considered. The conclusion is made that many risks and dangers are exaggerated, but there are also real threats to the harmonious development of society, including technocratism, mechanisticism, transhumanism, the destruction of traditional values, the transformation of justice into an algorithm, and information extremism.

Agrochemical science and progressive practice have developed requirements for sowing crops and, in particular, grain. They will place the seeds in a moisture-proof layer to a predetermined depth on the prepared bed. This study aims to investigate designing a combined colter for exemplary sowing of cereals. To that end, to avoid these shortcomings in the technology of grain crops sowing, a technical solution in the form of sowing sections is proposed. Based on the results, the principal amount of fertilizers should be applied locally, in the soil near the seeds, below the sowing level by 3...7 cm. The soil above the seeds should be compacted with a density of 1.15...1.25 g/cm3. Analysis of the designs of grain seeders and the proposed technical solutions for the combined sowing showed that there are no devices that meet all the requirements. It provides loosening of the soil in the area of fertilizer and seed placement, sows fertilizer to the bottom of the furrow, covers it with soil, forms a compacted bed under the seeds, sows the seeds on the compacted bed, covers them with soil and compacts it over the seeds.
