- Abstract
One of the main factors influencing the yield is the depth of seed sowing. Modern technology involves the use of disc seeders. But due to changes in the physical and mechanical properties of the soil, the force acting on the coulter when moving in the field causes the disk to move in the vertical plane, affecting the depth of the sowing. Equilibrium of the opener during operation can be ensured by using a flexible tubular element that is able to create a force compensating for the displacement of the coulter from the force of soil resistance. This mechanism allows the creation of an adaptive disc coulter, which provides the necessary depth in the seeding process. For a mathematical analysis of the equilibrium during working the coulter operation, we propose a model that takes into account the direction of the force action line and its variable value when the seeding depth is changed. The article presents graphical dependencies of the soil resistance force and the angle of inclination of the force action line to the horizon from the depth of the coulter stroke, obtained by the mathematical method. A comparative analysis of the existing and proposed models for calculating the coulter balance is carried out
