Motor fuel for tractor equipment includes mixed diesel fuel obtained by mixing commercial petroleum diesel fuel and vegetable oil. In such mixed fuel, vegetable oil acts as a renewable and environmentally friendly biological component. A promising biological component of the mixed fuel is rapeseed oil, produced by pressing from the rape. The article analyzes the main physical and chemical properties of rapeseed oil and mixed rapeseed oil-petroleum fuel with the percentage ratio of biological and oil components 25:75, 50:50, 75:25, 90:10. A binary diesel engine power system was designed, manufactured and tested for the operation of an MTZ-80 agricultural tractor with two types of engine fuel (petroleum and mixed), which allows changing the percentage ratio of the mixed fuel components during their mixing depending on the load and speed mode and temperature conditions of operation. The results of bench tests of the D-243 (4Ch11/12.5) diesel engine at the braking system during its operation with mixed rapeseed oil-petroleum fuel compared to its operation with commercial petroleum diesel fuel are presented in terms of power, fuel economy and ecological indicators.
Keywords: diesel mixed fuel, binary diesel power system, experimental studies, estimated indicators.

The work deals with the frame design of the device for liquid fertilizer application, watering and irrigation. The quality operation of this equipment will allow to meet the agrotechnological requirements for the cultivation of crops of a wide range, which largely determines the planned yields. The research was carried out using known principles of solid-state mechanics, theory of elasticity and strength of materials, as well as stress-strain analysis and modeling. In the course of the study, the loads acting on the frame of the device for liquid fertilizer application, irrigation and watering were determined. The beams and struts required for the structure were calculated and the materials were determined using material strength methods. The stress-strain analysis of the condition has shown that the strength and stiffness of the designed and modeled unit will ensure reliable operation of this unit. The device for liquid fertilizer application, watering and irrigation has been developed by the order of the Research Educational and Productive Center "Integration" for material and technical support of production, educational and practical, research and innovation activities of the university in the field of crop production, animal husbandry, processing, storage and sale of products, mechanization of agriculture; training and retraining of personnel, improving the quality of land resources used, increasing the economic efficiency of agricultural production, creating conditions for testing and transfer of innovative technologies.
Keywords: frame, fertilizer application, stress-strain analysis, modeling, agricultural machinery.

The article deals with the issues of increasing the work output of multifunctional machines with circular mode of operation (based on the sprinkling machine "Kuban-LK1") on sloping areas by eliminating the surface flow of the applied solution and increasing the bearing capacity of the soil in the movement zone of the last bogies of the machine. It was found that when the machine is used on sloping areas (with geodetic height difference), special emergency stops occur (three to five times) due to the over-wetting of the cultivated area, which has a negative effect on the coefficient of use of the shift time. It has been revealed that the bearing capacity of the soil can be increased by reducing the intensity of the supply of the working solution by installing improved devices to regulate the flow and pressure characteristics and the spray of sprinklers. Technical solutions to reduce the intensity of the supply of working solution are justified with their experimental verification under the laboratory, field and production conditions. Experimental studies have shown that the combined use of devices for regulating the supply of working solution by sprinklers of the multifunctional machine with circular operation in the conditions of sloping surfaces can ensure reliable and qualitative performance of the technological process of irrigation. In this case, the coefficient for the use of shift time K_cм and thus the work output of the machine  increases ω by 15-17%.
Keywords: multifunctional machine, work output, cross-country performance, bearing capacity, supply intensity, flow regulator, divider, shift time use coefficient.

The article presents an analysis of the main factors influencing the process of water-induced and technological soil erosion on sloping lands. On the basis of the research carried out, a technological procedure for erosion control treatment was developed, which, simultaneously with non-moldboard loosening of soil, enables the creation of an erosion-inhibiting micro-relief in the form of coulisse on the surface of arable land. The article presents the structural-technological scheme of the tillage tool and the parameters of the coulisses it produces on a sloping plot with a steepness of up to eight degrees. An agrotechnical and operational evaluation of the tillage tool was carried out as part of the study.
Keywords: water and technological erosion, sloping lands, tillage tool, tillage, anti-erosion microrelief, coulisse.
