Summary: To reduce energy consumption in ploughing, the tractor within the aggregate with a frontal plough should have a narrow gauge and high draft and linkage properties. It is suggested to increase the latter ones not by ballasting the tractor or changing the parameters of its under-carriage system, but by using both the mass of the frontally mounted (frontal) plough and the vertical component of its draught resistance. Synthesis of the scheme and justification of the parameters of the ploughing aggregate were carried out by simulating the conditions of its operation on the PC. Two variants of attachment the frontal plough to the frontal linkage mechanism of the tractor were regarded during the research: the first one is characterised by the fact that the inclination angle of the central drawbar of the frontal linkage is less than the inclination angle of the lower links; in the second variant – on the contrary. For a stable movement of the frontal plough along the depth of ploughing with minimal waste of energy for rolling its supporting wheel and insignificant deformation of the soil, the vertical reaction upon the supporting wheel should be, on the one hand, greater than zero, but, on the other hand, close to it. When the frontal plough is pivotally attached to the frontal linkage mechanism of the tractor with the inclination angle of the central drawbar larger than the inclination angle of the lower links, the vertical load on the supporting wheel of the ploughing implement is greater. In contrast to the setting variant of the frontal linkage mechanism of the tractor, when the inclination angle of the central drawbar is less than the inclination angle of the lower links, the vertical load on the supporting wheel of the ploughing implement is 5.5 times larger. The maximum values of the reaction on the supporting wheel are achieved at various inclination angles of the central drawbar and the lower links of the frontal linkage mechanism of the tractor.
