[0002] A harvester is a machine that harvests crops in one go. It harvests and threshes the grains simultaneously, collecting them in storage bins before transporting them to transport vehicles via conveyor belts. Harvesting can also be done manually, with corn, rice, wheat, and other cereal crops' stalks spread out in the field. Grain harvesters then pick up and thresh the stalks. These harvesters, including harvesters, reapers, balers, combine harvesters, and threshers, are developed based on various harvesting and threshing tools.
[0003] Most of the existing harvester headers can only be installed on the headers of the same model of harvester, and cannot be adapted to headers of different sizes. This will result in the need to carry different types of protective covers as spares when working on different types of harvesters, which greatly limits the use of protective covers.
