The studies conducted at WSI Berlin-Wartenberg have shown that mathematical modelling of individual phases of flight of separated components of the mixture on cascades of complex potato harvesters is impossible. Photographic and cinematographis techniques are the appropriate means of determining flight coordinates. The method of chronophotography used in the experiment has the advantage of representing the analyzed sequence of photographs on a single image produced under uniform conditions. This greatly simplifies the analysis and increases the amount of received information. Furthermore, equipment and material expenditures are relatively small.

The paper presents results of the studies dealing with evaluation of the horizontal projection of the trajectories of the tubers soiled to various degrees which were fed by rotary elevating drum on the Packman and Peis separators. Process of feeding separators with the crops of two levels of soiling was registered on the film by the Krasnogorsk 16 and Pentaflex AK 16 motion picture cameras and by the stroboscope method using still camera. There has been stated a decreased value of range of the horizontal throw of the tubers soiled at the surfaces in the range 7-11% when compared with the tubers soiled within the range og 1-3%. These differences are statistically significant. The decreased range of the throw of the tubers is the factor which can unfavourably affect uniform distribution of material separated by the separators of the machines harvesting potatoes.
