In recent years, the development of wheat combine harvesters has been rapid, the technology is mature, and the structure is becoming more reasonable, but the further development is facing the applicability of great challenges. Small combine harvesters have their own uniqueness and have their own market level. Through years of understanding of the combine harvester, it is concluded that its development can be roughly divided into the following five situations:
First, the tentative type is gradually developed from low-cost small to medium-sized; secondly, the rural economy in the plain area is developing further, but the farmers are not rich enough, the time for using the combine harvester is not long, and the small combine harvester develops fast and vital. Third, some minicomputers have gradually been replaced by medium-sized self-propelled combine harvesters; fourth, product quality is the key to guiding sales; fifth, the sales of medium-sized self-propelled combine harvesters and the reform of planting forms related.
