Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to the technical field of a harvester transmission device. Background Technology

[0002] With the development of modern agriculture, the harvesting of various crops is now achieved through mechanization. Compared with traditional vehicles, harvesters are characterized by the fact that in addition to the transmission device for vehicle movement, they also need to have a crop harvesting device.
