The article is devoted to the issue of development and analysis of the proposed design of working bodies for performing the operation of additional cleaning of beet heads from plant residues. In accordance with the agrotechnical requirements for growing this crop, the developed working body must provide an appropriate degree of cleaning of sugar beet heads. It is also necessary to ensure minimal injury to root crops and prevent them from being knocked out of the soil.

The issue of cleaning sugar beet heads was addressed by both domestic and foreign scientists. Designs of both active and passive working bodies are known. Passive working bodies are quite simple to manufacture, but require a high-quality tracking system and ensuring compliance with the speed of this system and the movement of the unit across the field. At the same time, active working bodies of the disk type also require the use of a tracking system but provide a better degree of cleaning. Active working bodies with flexible cutting elements provide a better degree of cleaning, do not require a tracking system for height correction, therefore their development is an urgent and necessary task.

The publication considers the issue of studying the kinematics of the movement of an improved working body of a sugar beet top cleaner. An analysis of the working environment for this pre-cleaner was carried out. A three-dimensional model of a sugar beet top cleaner was created, and a video sequence of possible movements of the working bodies was obtained. As a result of the analysis of the obtained video sequence, it was noted that the use of this type of drive ensures an increase in the effective overlap of the zone of possible location of root crop heads, as well as the action of the working elements of the pre-cleaner in the direction of maximum rigidity of most of the top residues, which improves the quality of cleaning of root crop heads.
