Design and Test of 4YZ-3B Self-propelled Corn Harvester

In view of weak links in integration of agricultural machinery and agronomy in whole process mechanized harvesting of maize in Shanxi Province，4YZ-3B self-propelled corn harvester was developed.Design ideas and technical parameters of key components of the machine were introduced，and the prototype was tested to provide suitable models for corn harvesting to adapt to different regions，different planting modes，different varieties，different harvest periods，different yields，and different ear heights.
