Corn harvester: one-row corn ear picking and stalk crushing function. Equipped with full-load ear bucket, removable filling bag, and adjustable stubble height. The upgraded gearbox has a safe working clutch, a small turning radius, and easy operation. After the corn is harvested, the machine directly crushes the stalks, but the peeling is not clean, and the ear height can be harvested when it is more than 60 cm.
