Oscillatory movements of trailed agricultural machines have been studied theoretically and analysed in the process of their movement along the surface irregularities of soil. On the basis of differential equations of the movement of a mechanical system in a longitudinal vertical plane (using the Lagrange equations of the 2nd kind) a mathematical model of the oscillatory movement of a trailed agricultural machine aggregate due to the soil irregularities has been developed.
W pracy przedstawiono model matematyczny wyorywacza lemieszowego uwzględniający jego parametry kinematyczne i geometryczne. Przedstawiono rozkład sił działających na burak i lemiesze podczas procesu wyorywania. Wyprowadzono wyrażenia na prędkość roboczą maszyny i czas wydobywania buraka z gleby.

The study presents a mathematical model of a share lifter, taking into account its kinematic and geometrical parameters. The distribution of the forces acting on the beet and the shares during the lifting process was presented. The expressions for the working speed of the machine and the time of lifting the beet out of the soil were derived.
