Zusammenfassung
This book summarises the proceedings of the 75th conference “LAND.TECHNIK – AgEng 2017”, which took place in Hannover on November 10th and 11th following the tradition of odd years. Therefore it is a well established prelude to AGRITECHNICA, the world’s most important fair for agricultural machinery, which started on November 12th with the preview days. The conference was successfully organized in cooperation with the “Max Eyth Society for Agricultural Engineering” (VDI-MEG), a technical division of the Association of German Engineers (Verein Deutscher Ingenieure, VDI) and the European Society of Agricultural Engineers (EurAgEng). This collaboration has been accepted both by academia and industry at national and international levels. During recent years the number of participants has increased to about 1000 from more than 15 nations. The conference offered 75 presentations about the latest innovations, machine developments, and technical concepts and methods as a foretaste ...
