A technique of fast shots is frequently used in the investigations of farm machines kinematics. The article discusses an example of its application for examining a corn cob movement in a separating unit of the adapted combine harvester (examinations were performed on a special test-stand). The process was registered on a NP 27 film with the frequency of 500 frames/sec. A film picture was transferred with a video camera to a PC computer disk with FG-2000 graphic card and suitable software. Coordinates of the corn cob geometrical centre were read off and with the known time base, speed, acceleration and kinetic energy of the corn cob, when it was being separated from the stem, were calculated. In this way it was possible to obtain more precise information about the process which occur when a corn cob is separated from the stem.
