Opolagra’s machinery show consists of about 100 machines working live! on the field, being discussed by a professional speaker. The attraction of the daily demonstrations of machines is a special obstacle course to compare fields sprayers. The obstacle course was developed by the DLG in cooperation with experts and practitioners from the agricultural sector. It is the only track in Europe, meeting the requirements of ISO standards. Sprayers are working in conditions similar to the natural, so visitors can see themselves the functionality of presented machinery.
