The article provides the analysis of regulatory frameworks of environmental friendliness of tractors, machinery and equipment existing in the territory of the Customs Union and the Russian Federation, and the methodological support for obtaining standardized indicators. It also considers the problem relating to travel of non-road self-propelled vehicles on the public road network.
To ensure the minimal damage of soil structure, it is proposed to determine the maximal slipping of wheeled movers taking into account the value of their permissible pressure on soil in horizontal plane. As a result, it is established that for the substantial reduction of soil structural damage during agricultural works in spring period the maximal permissible values of slipping of wheeled movers of tractors of 5, 3 and 1,4 tractive classes have to be equal to 15, 12 and 9% respectively. In summer and autumn periods, the values of maximal slipping can be greater and, accordingly, be equal to 20, 16 and 13%.
It is shown that when performing work on the restoration of parts operating in abrasive environment, the formulation containing 60-70 pts. wt. of natural sand and 30-40 pts. wt. of epoxy adhesive is the most effective in terms of adhesion strength.
A design diagram of agricultural implement providing efficiency increase through the use of self-adjusting mechanism of angles of working organs entry into soil is presented.
Drying of high-moisture and heat-labile material requires the substantiation of temperature and duration of process. This is due to the necessity of preserving of product quality and economical efficiency of process. Use of infrared drying allows to solve this problem, because the duration is significantly reduced in comparison with convection drying.
The results of theoretical and experimental studies of formation of flax straw bales by round balers are presented.
A new calculation method for steering linkage based on the equation of a circle is proposed. The method can be used with iterative method of dynamic calculation for steering system of wheel tractors.
The paper presents the results of experimental studies of biogas spark-ignition internal combustion engine on the basis of ЯМЗ-236 diesel engine; it determines the dependence of average operating emissions of toxic components in the engine of that type on the chemical composition of fuel.
The paper considers the processes of breakaway and acceleration of agricultural machine-tractor unit with electric traction.
The article presents the results of studies for substantiation of operating weight and tractive class of universal wheeled tractor for working in cotton growing with wide-cut seeders and cultivators.
Method and device for monitoring and diagnosing the quality of engine and hydraulic oils are proposed. This aim is attained on the assumption that main quality parameters of engine and hydraulic oils are the alkali or acid number and the content of mechanical impurities.
The article presents the analysis of factors which must be considered when calculating the cumulative costs for substantiation of composition of tractor fleet of the north region of Kazakhstan.
The paper presents the analysis of equipment protecting the cab and operator of mobile power unit from high insolation. Special attention is payed to the combination of thermophysical properties of protection devices, including the capacities of reflection, thermal insulation and heat removal. A number of patented designs improving working conditions is proposed.
The article presents the results of investigation of qualitative indicators of straw chopping by combine harvesters under various operation modes.
The article proposes a cultivator hoeing the soil and combing the weeds in protection zones of plants, performing various process operations without additional set of working organs.
