“…Based on the previous results, the authors considered the possibility of reducing the maximum pressure of the tractor, based on Fig. 2 and formula (1), obtained taking into account that K; where K 2 = 1.5 was the coefficient of longitudinal non-uniformity of pressure distribution over the support area of the tire-soil contact [6,[8][9][10][11][12][13][14].…”

Modern highly mechanized agricultural production is characterized by the incompatibility of simultaneous matching of the maximum pressure of agricultural mobile equipment movers on the soil and the possibility of increasing the tractors energy saturation when equipping them with existing wheel engines.(Research purpose) To coordinate the maximum pressure on the soil with the permissible norms, weight utilization factors and the level of tractors energy saturation.(Materials and methods) The authors used a calculated method for determining the maximum pressure on the soil using a universal tire characteristic.(Results and discussion) The authors found that when performing spring works on closing moisture and sowing row crops at a maximum pressure of 80 kilopascals, corresponding to all types of soil, the most mass universal row tractor Belarus 1020 had a maximum pressure of 150 kilopascals, which was 70 kilopascals higher than the permissible one for the corresponding crop shortage. They found that replacing ordinary tires with agrophilic tires could increase the area of the contact spot by 16 percent, while reducing the coefficient of unevenness and increasing the coefficient of use of the adhesion weight. The main condition for replacing ordinary tires with agrophilic tires was to keep the traction force unchanged.(Conclusions) Summarizing the results of the research as agrophilic direction, ensuring the compliance impacts on soil and positively solving the problems of saturation, it is possible to recommend the development of navigation systems in achieving utilization hitch weight equal to 0.5 (low tire pressure), equal to 0.6 (rubber joint with torsion bar suspension) and 0.7 (rubber track). It was found that the conducted research, taking into account the available data on traction tests of the T-250 tractor, would allow to include an agrophilic concept with a hypothetical dependence of the adhesion weight use factor on the longitudinal unevenness coefficient in the revised State Standard 27021-86 “Agricultural and forestry Tractors. Traction classes”.

“…The basic agrotechnical requirements for the agricultural technical TTD were developed at the Federal State Budget Scientific Institution of Science and Technology of the VIM. These requirements are based on the existing scientific and technical reserve, the results of the analysis of promising agricultural technologies and existing requirements to limit the impact on the soil [4][5][6][7]. The layout and design study of the TTD on increased tires, including but not limited to adapting the transmission and steering of mass-produced cars to agrotechnical requirements, was carried out at the Technical Cooperation Center at MSTU named N.E.…”

Now days there is no a single mass-produced vehicle for agriculture which does not match requirements of the state standard for the maximum allowable impact of movers on the soil. This leads to significant losses and under-harvest of agricultural products. As a promising direction for increasing the efficiency of the transport infrastructure of agricultural production, it is proposed to develop an environmentally friendly transport and technological chassis for agricultural purposes.

The analysis of security with the mobile power tools (MPT) on 1000 hectares of an arable land in Russia and some countries of the world is submitted, the created deficiency of tractors on traction classes and type of running systems is disclosed, the dominance in the machine tractor park of wheel tractors of a class 1,4 Belarus 82.1 is revealed. The provided data confirm practical decrease of volume of the machine and tractor park and demand acceptance of the state measures for its restitution. Special attention is paid on the fact that the caterpillar component of the park have dual purpose, which share in the common park approaches now over a zero level is extremely unacceptable for soil and climatic conditions of Russia. It is shown that in statistics of sales of tractors in Russia in recent years the larger share of the market is occupied by agricultural machinery of domestic production. From 2013 to 2016 the share of the domestic enterprises in the value of sales grew from 22 to 35 %. The main vector of development of MPT allocated tendencies of replacement of kinematic communications by the informational, being a systemic basis use of digital technologies. The near-term outlook of the choice of the technological direction of the advancing development of agricultural mobile power tools, competitive at world level, and the prospect of search works on creation of robotic agricultural MPT are considered. It is noted that applications of the integrated and high-precision models of farming, including technologies of precise agriculture, rises the need for the automated and robotic MPT. It is shown that in the near future agricultural robots will automate all hard field work: plowing, landing, application of fertilizers, collecting and transportation, a harvest etc. and will create basically new market of MPT.
