A shortage of class 2 and class 3 tractors was observed in peasant farms. As a solution to this problem, it was proposed to develop a technological module that would increase the versatility of class 1.4 tractors by transferring them to a higher traction class. (Research purpose) The authors aimed to substantiate the nominal operating power of the engine for a tractor with a technological module. (Materials and methods) To calculate the required power, the authors proposed a method that takes into account the design features of the modular construction of a machine-tractor unit. (Results and discussion) The authors showed that for a modular power unit with a 6K6 wheel arrangement, it is necessary to consider a number of additional factors having an impact on the accuracy of the calculation: firstly, the tractor’s traction and coupling properties depend on the number of driving axles; secondly, the wheel slippage along individual axes is not the same and occurs due to a constructively conditioned kinematic discrepancy in their drive; thirdly, the three-axle transmission efficiency can be determined only as a total indicator of three transmission branches, that is, to drive the tractor front and rear wheels and, separately, to drive the wheels of the technological module. The authors compared the required engine power when using a tractor with ballast and that with a technological module.  (Conclusions) It was determined that in order to achieve the maximum traction force of adhesion on the hook when moving to the next higher traction class, it is necessary that the tractor, that the technological module is joint to, has the energy saturation of 2.00-2.41 kilowatts per kilonewton, which corresponds to traction and energy concept tractors whose engine power cannot be realized through traction. It was found that the power saturation of the tractor with the technological module will be equal to 1.59-1.65 kilowatts per kilonewton, which corresponds to the tractor of the traction concept and allows realizing the built-in engine power through traction.

The main reason for using heavy tractors is the high energy saturation of modern agricultural machinery. For the full engine power realization, the tractor must have high traction performance. Ballasting, the drive wheels doubling, transport and technological modules increase traction. (Research purpose) To determine the best way to increase traction. (Materials and methods) The authors calculated the propulsors pressure of the Terrion 3180 tractor loaded with ballast weights and aggregated by the MES-300 transport and technological module on the soil using mathematical modeling. It was noted that the pressure on the soil is 38 percent less when using the transport and technological module, with the same traction. (Results and discussion) The authors analyzed the design of the MES-300. It was revealed that to improve the transport and technological module operation, it was necessary to reduce weight. It was found that when using the transport and technological module to increase the tractor traction, fuel consumption increased by an average of 3 percent. The authors showed that it was possible to reduce consumption by improving the transmission, which was based on the drive axle from the T-150K tractor. They found out that the effective drive scheme was an individual drive of the drive wheels, which allowed to combine the positive sides of the differential and hard drive. They performed mathematical modeling of a transport and technological module with various types of transmission (mechanical, hydrostatic, electric). It was stated that hydrostatic transmission was the most efficient type of transmission in terms of fuel economy. (Conclusions) The authors determined that the modernization of the MES-300 through the use of a transmission with an individual drive on each wheel had positive results: a change in power and torque supplied to each wheel; reduction in kinematic mismatch and power circulation; increase fuel efficiency.

To increase productivity in agricultural production, combined wide-grip machines are being created, aggregated with tractors of traction classes from 5 and higher. In addition, according to agrotechnical requirements, the pressure of the mover on the soil should be minimal, as well as the number of passes over the surface of the field. These contradictions can be solved by ballasting of tractors, which allows using engine power to increase tractive effort. Ballasting affects energy saturation. Increased energy saturation with appropriate ballasting makes it possible to compose machine-tractor units (MTU) according to a more accurate ratio of the tractor pulling force and the unit's pulling resistance. The most in demand in modern agriculture are tractors of 5-6 traction classes produced by domestic and foreign tractor-building plants with an internal combustion engine with a capacity of 220-320 kW and an operating weight of 115-150 kN. The article contains a two-way analysis of variance, which makes it possible to determine the greatest influence on the ballasting of a tractor. A diagram is constructed that gives an idea of which of the studied brands of tractors can be recommended for performing agricultural operations, taking into account ballasting and compliance with agrotechnical requirements.

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.

Improving the traction properties of mobile power tools is one of the most important tasks of modern tractor construction. The use of transport-technological modules (TTM) helps to solve this problem, but to ensure the best indicators of fuel economy and stabilization of a machine-and-tractor unit (MTU), the TTM driving wheels should be driven individually, which can be ensured by a microprocessor control system. Therefore, the study goal is to make an algorithm for controlling the driving wheels of the TTM, which will ensure the best characteristics of a MTU. To achieve this goal, the authors used mathematical modeling and graph-analytical methods. They are necessary for stating the main relationships and setting algorithm conditions that will optimize a tractor’s traction force and power consumption, as well as stabilize its movement trajectory. The operation of the microprocessor system consists in obtaining data from external sensors and determining the actual speed, skidding and direction of travel. The microprocessor system compares these parameters with ideal conditions, described with mathematical relationships, and based on the developed algorithm, corrects the rotation speed and power distribution between the driving wheels of a TTM.

Engine Power

A method for estimating the power characteristics of the car engine in various driving regimes is proposed. It is determined that the volume of the free power (engine power reserve) allows the driver to implement the turning parameters and the time of its completion, which are set by the steering parameters, position and the speed of the steering wheels rotation. The engine power reserve is necessary to provide the required maneuverability indicators. The engine power during maneuvering is spent on overcoming the resistance to movement and on providing the impact controlled by the maneuver. The first component of the engine power can be called connected, and the second one can be called the free one or a controlled component. The received analytical expressions allow carrying out at the design stage a rational choice of capacity of the engine by the condition of maintenance of demanded properties of maneuverability. The developed method for constructing the refined acceleration characteristics of the engine makes it possible to determine the dynamic capabilities of the car, taking into account its design features and operating conditions.

The lancet cultivator shovels wear out intensively under the action of abrasive soil particles, which degrades the quality of cultivation, violates agricultural requirements and leads to an increase in traction force and fuel consumption. Strengthening of lancet shovels allows increasing their wear resistance and durability. (Research purpose) The research purpose is in analyzing the methods of strengthening the lancet cultivator shovels and identifying their main advantages and disadvantages. (Materials and methods) The article reviews the methods of strengthening the lancet cultivator shovels described in domestic and foreign literature and specialized magazines. (Results and discussion) It was found that the issue of strengthening the working parts of tillage tools and the cultivator shovels in particular is given much attention and the problem of their wear is currently relevant. There are many methods of strengthening that differ from each other in the principle of strengthening, as well as in the labor intensity, cost of materials and equipment for performing strengthening. The article presents a diagram for a visual comparison of methods for strengthening the lancet cultivator shovel. (Conslusion) Analysis of methods for strengthening lancet shovels showed that it is possible to increase their wear resistance up to 5.8 times. However, the methods of hardening that provide the greatest increase in wear resistance of working parts of tillage tools require large amount of time, labor and material costs. It was found that the method of hardening by surfacing individual wear-resistant rollers on the working surface of the arrow legs of the cultivator becomes the most promising. This method provides an increase in wear resistance up to three times with high productivity and simplicity of the hardening process, and it’s relatively cheap.
