Brave 4YZQS-4A/4B Ear and Stem Harvesting Self Propelled Corn Harvester Product Introduction

1. Can be used for harvesting both straw and corn ears simultaneously
2. By adopting the technology of green feed harvester, the grass throwing drum can achieve a wide range of height adjustment, meeting the requirements of different feeding trucks, ensuring that the grass does not stick to the soil and is evenly cut into sections
4. Equipped with a 270 horsepower National III engine; Integrated intercooler combined water tank
5. The chassis is equipped with a hydraulic dedicated drive axle, making the operation lighter and more flexible

1. Adopting a composite cutting platform, both ear picking and straw harvesting are completed simultaneously (the upper cutting platform consists of a cutting blade for ear picking, a supporting mechanism, and a strong feeding structure; the lower cutting platform consists of a reciprocating cutting blade and a chain rake conveying system). The upper and lower cutting platforms can adjust the harvesting height separately according to the crop situation in different harvesting areas



2. Peeling machine

3. Grass throwing bucket
