The studies were concerned with distribution of potatoes and soiling fed on the pin conveyors of the separators of the potato combine-harvesters Z 644 and E 667/4 by the rotary elevating drum. There were analysed 90 meters of 16 mm film exposed in the field for each of these combines. The film was taken with the speed of 48 frames per second. Moreover, photostroboscope was used in the laboratory for recording on the single frame the trajectory of falling of potatoes on the pin conveyor of the combine Z 644. The analysis of films and stroboscope photographs was concerned with position of points of falling of tubers and soil clods as well as with so called "relaxation points", i.e. points from which movement of the filmed potato or clod occurs simultaneously with that of the belt of the conveyor. Distribution of points of falling in the case of the combine Z 644 has a central pattern with a slight deviation towards the side which is closer to the cascade. On the other hand, the "relaxation region" for particular components is transfered to the edge of the belt. Similarly, in the case of the range of falling the side closer to the cascade is also prefered when the combine E 667/4 is considered. Moreover, the material is being transfered towards the separator rather on the left-hand-side of the belt, i.e. to the siede which is more distant from the cascade.
