Abstract
The purpose. To determine influence of kinematic and design parameters of top-gathering machine upon quality of clear cut of haulm at oscillations in longitudinal-vertical plane of top-gathering apparatus at frontal mounting on wheel tilling and aggregating tractor. Methods. Methods of simulation which are based on principles of higher mathematics, theoretical mechanics, on the solution of system of differential equations, creation of programs and numerical solution on PC. Results. Equivalent scheme is developed for top-gathering machine, which is frontally mounted on wheel row-crop tractor at its oscillations in longitudinal-vertical plane, with consideration of all forces which originate in view of kinematic initiation which originates at driving on soil surface with irregularities in row widths of sowings of sugar beet, and also owing to elastic-and-damp properties of its support-patterning wheels. Conclusions. By results of numerical modeling final expression is gained. That allowed determining vertical movement of the lower end of rotor top-gathering apparatus at oscillations of the top-gathering machine in longitudinal-vertical plane.

Key words: sugar beet, haulm, harvesting, rotor top-gathering apparatus, oscillations, differential equations, amplitude, frequency.
