Abstract. The paper discusses the advantages of power-driven tillage tools as compared with machines with passive working elements, which provide for quick changing and controlling of the quality of soil crumbling, guided by the condition of the treated areas and the engine power of the power source used. (Research purpose) To develop a system for automatically maintaining the magnitude of a selected kinematic parameter during the operation of a rotary cultivator equipped with a hydraulic drive of working elements. (Materials and methods) The authors have conducted research involving patented materials on the use of automated process control systems for pre-sowing soil cultivation with tools featuring hydraulic actuators of working elements. (Results and discussion) It has been determined that the frequency comparison blocks may contain pulse shapers that are converted by the electronic control unit into a signal sent to a low-speed, high-torque adjustable motor of a Danfoss MGP-160 type. A system has been developed to automatically maintain the value of a selected kinematic parameter of a rotary cultivator by equipping its working elements with a hydraulic actuator with a two-stage hydraulic distributor controlled by an electronic unit that allows automatic adjustment of the required speed of the rotary drum cutters, optimal for the treated soil background. (Conclusions) The authors have identified a schematic diagram of an automated hydraulic drive of a rotary garden cultivator capable of tracking and adjusting the rotary drum speed.Π Π΅ΡΠ΅ΡΠ°Ρ.

Determining the speed of soil particles during the covering of set onion with a disk-type working element featuring a soil guide
In Russia, the major share of vegetable products is produced during the period of March to August. This is due to the inadequate volumes of vegetables fit for long-term storage, and the use of technologies of early production of vegetable cultures. Apart from the above, vegetable farming is highly dependent on imported seed stock. In view of the above, import phaseout and improvement of competitiveness of vegetable cultures in Russia should focus on the development of technologies of production of storable products, as well as on methods of early harvesting of vegetables (during the period of May to July). With regards to the production of bulb vegetables, this problem may be solved by expanding industrial cultivation of onions from set onions, as well as planting of both seeds and seedlings during the autumn season. In particular, techniques of production of set onion, bulb onion from seedlings, and of blackseed onion have poor scientific and methodological background. This deficiency results in a gap between domestic and international process and engineering aspects. This calls for the development and introduction of machines designed for production of onion from seedlings that would be in line with the modern level of development of farm machinery industry for vegetable production
