Abstract: In order to systematically analyze research frontiers in field of international agricultural machinery and provide support for science and technology planning and science and technology decision-making in this field，a bibliometrics method combined with qualitative literature study and review，and an expert consultation was applied to reveal research frontiers on agricultural machinery in perspective of basic research and engineering technology research respectively.It was concluded that research frontiers were mainly focused on：①agricultural sensors such as wireless sensor networks，sensor system algorithms and software；②navigation control，optimization and tracking of path planning，attitude control and related algorithms of agricultural robots such as autonomous agricultural machines and wheeled mobile robots；③unmanned aerial vehicle navigation，guidance and control；④remote sensing technology and geographic information systems.Informatization，automatization and intelligenatization significantly oriented development of future agricultural machinery and equipment technology.Core papers were mainly from the United States，Italy，China，Australia，Spain and Denmark.
