The article presents information on the energy assessment of the functioning of the sowing section, the chisel coulter of which has an acute angle of entry into the soil. High uniformity of seed wrapping in depth is ensured by the retaining heel. A spring-loaded disk cuts plant remains in front of the coulter, and a rolling wheel provides a given depth of movement of the coulter. It is assumed that such a section can be used both in traditional and direct methods of sowing or under the condition of minimal soil preparation. The proposed method of establishing the energy indicator – of the traction resistance of the seed section on its movement in the soil during the execution of the technological process, provided that variable influential factors, such as the depth of the coulter and the working speed, are taken into account. Considered features of technical support of field experimental research. Thus, for the aggregation of the experimental section, a trailed sowing module was used, which was developed for the study of the working bodies of tillage and sowing machines. The originality of traction resistance control lies in the use of a digital traction meter for this, which connects the two moving parts of the trailed device of the seed module. To record numerical values, you can use a high-speed movie camera or an ordinary modern phone with a video camera. The following are obtained experimentally by the dependence of the traction resistance of the proposed structure of the seed section on the indicated influential factors and the range of change of its actual values in the range from 0.12 to 0.4 kN. The obtained indicators confirmed the possible effectiveness of using the proposed design of the sowing section as part of various sowing machines with significant savings in energy costs.
