Abstract: The wide spray bar spray is one of the representative models of high-efficiency agricultural machinery, which can efficiently complete the task of plant protection of agricultural machinery. To further improve the efficiency and reliability of the wide spray bar spray in practical application, the use of the wide spray bar spray was deeply analyzed, the problems existing in the production practice were systematically sorted out, the standardized driving and operating methods of the wide spray bar spray were elaborated, and the daily maintenance, common fault handling, maintenance technology and other aspects were introduced. In addition, the importance of improving awareness of standardized driving operations and safety production was emphasized, hoping to better guide production practice.
