Therefore, the use and maintenance of the combine harvester have a great influence on the service life of the combine harvester. In order to extend the service life of the combined harvesting, it is necessary to use the harvester properly and reasonably, and at the same time to maintain and maintain the harvester. 1 combine harvester rational use
