“…The food security of the country undoubtedly depends on the yield of cultivated crops, which largely depends on the timeliness and quality of technological operations, including the main tillage (plowing), continuous cultivation before sowing and sowing itself [1][2][3]. However, the technical, economic and qualitative indicators of the performance of technological operations associated with the contact of the operating elements of aggregated agricultural machines and tools with different horizons of cultivated soil are reduced due to the fact that all links of machine-tractor units (MTU) experience the negative influence of external forces and moments that have a stochastic character [4][5][6][7][8].…”

“…As a result of the impact of variables in the nature of fluctuations in the load on operating elements of agricultural machines and tools, the productivity of the MTU decreases with the increase in the cost of operations, such agrotechnological indicators worsen as the depth of soil cultivation, uniformity of seed placement, and others [2,3].…”

The aim of the work is to scientifically substantiate a way to improve the technical, economic and agrotechnological performance indicators of machine-tractor units, compiled on the basis of traction power equipment of category 1.4, the main technological operations in the cultivation of various crops by reducing the level of dynamic processes in their connections. It is established that the elastic damping mechanism with nonlinear characteristics and optimal parameters installed in front of the drive shaft of the power transmission of a traction power tool of category 1.4 provides favorable conditions for the functioning of all links of machine-tractor units for agricultural purposes, with them the main technological operations are performed, which contributes to the improvement of its technical, economic and agrotechnological indicators. The installation of an elastic-damping mechanism with nonlinear characteristics and optimal parameters in front of the drive shaft of the tractor traction category 1.4 provides an increase in productivity by more than 8% while reducing specific fuel consumption by 9% or more, as well as improving the quality performance of machine-tractor units when they perform basic technological operations.

The current paper has presented the study on theoretical dependences of the optimization parameter (the degree of transmission transparency) on the design factors of elastic-damping mechanism (EDM) in the transmission for tractors of small traction class (14 kN). The purpose of the study was to obtain a unified functional relationship that integrates early study results. The determination of a unified function was based on reaching a compromise by the method of indefinite Lagrange multipliers. With the help of the function, there have been obtained the dependences of the effect of EDM design factors on transmission processes when performing the main agricultural operations. Using a method based on finding a compromise solution (method of indefinite Lagrange multipliers), there have been substantiated design parameters of the elastic-damping mechanism in the tractor transmission and there has been identified an optimization parameter of the Lagrange function. For a better understanding of the obtained dependence, there has been carried out a three-dimensional visual analysis. Each factor used in the Lagrange function was a physical parameter of an elastic-damping mechanism. The resulting equation has given an opportunity to control mechanism parameters in natural operating conditions. The obtained Lagrange value has demonstrated that the mechanism absorbs 32% of fluctuations in the external traction load of a tractor, when working with the main agricultural tools.

The aim of the work: to establish the functional indicators of a cultivator unit based on a wheeled mobile power vehicle of traction class 1.4 when its driving wheels are equipped with tires of size 18.4R-38 of various models (206B, TM300S, VL-32). The increase in the performance indicators of the functioning of any machine-tractor unit depends largely on its working speed and the width of the grip, which implies the use of mobile energy means with high traction and energy indicators at the lowest level of dynamic processes in the links of the machine-tractor unit. For wheeled mobile power equipment, the achievement of high traction and energy indicators is determined by the properties of the tires of the driving wheels. Analysis of traction test data showed that the MTZ-80 tractor with VL-32 tires mounted on the propellers had the best traction performance compared to other tested models.
