The Agricultural Engineering Board of the Hungarian Academy of Sciences which supervises the development ofthis branch organises annually a conference at Gödöllő, which is the central place of the Hungarian agriculturalscientific activity.During the sessions, research scientist, developing engineers, experts of institutions engaged in agriculturalengineering development strong in numbers the organizer, the hungarian universities and other higher grades ofeducation, the research institutions: Hungarian Institute of Agricultural Engineering at Gödöllő, Faculty of MechanicalEngineering of the St. István University at Gödöllő and foreign guests give account of their results obtained in theresearch work and development of agricultural machinery.This yearly English-Language publication the “Hungarian Agricultural Engineering”, started at 1988, containsselected papers presented at the conference of 2004. We do hope that this publication will be found interesting to a bigpart of agricultural engineers.
