dc.description.abstract <p>Rotary tillers with flat tines are widely used in agriculture. In this study, the power requirement of an active tillage tool was investigated using a theoretical procedure. The goal of this work was to determine and analyze the soil resistance forces on the tine of rotary tiller. The laws and rules of theoretical mechanics were applied in the research. Theoretical studies obtained analytical relationships for determining the soil resistance forces acting on the chamfers and side surfaces of the tines of the rotary tiller, as well as the torques associated with these forces. The analysis of the obtained analytical expressions showed that the forces of the tiller tine is mainly influenced by the mode of operation of the tiller, the design parameters of the tine and the physical and mechanical properties of the soil. With an increase in the index of the kinematic mode of operation, λ, which is the ratio of the peripheral speed of the tine to the forward speed of the tiller, the resistance force of the flat tine decreases, and then takes a negative value. At λ > 2, the resistance force of the tine is directed towards direction of movement. In this case, a driving force is formed, the maximum value of which is reached at λ =2-2.2</p>
