Agricultural machinery promotion refers to the application of agricultural machinery and agricultural mechanization technology in the whole process of agricultural production, including before, during and after production, through experiments, appraisal, demonstration, training, guidance and consulting services. With the continuous progress of the times and the needs of modern society, higher requirements for agricultural machinery promotion are put forward, but there are still many problems in the promotion of agricultural machinery, which restricts the sustainable development of agricultural machinery promotion. Based on this, the paper puts forward some countermeasures to the existing problems.
