Features:
1. 4YZ-4A Small-interval corner harvester is to attach newly developed small-interval headers to 4YZ-3 machine body. The main feature is the design of small interval of headers, 520mm reaping interval can meet the conditions of use for most of inland area with corn growing interval of 450-550mm. The harvester reaps front to front, which can raise working efficiency and harvesting result greatly. It can complete the operation of corn picking, corn collection into box and straw crushing and returning to field at the same time.

2. The standing straw poking chain of headers adopts automatically tightening spring, thus it is free from adjustment and easy to use.
3. Corn picking plate adopts underlying structure to effectively reduce stem breaking rate when corns are picked by headers.
4. MID crusher adopts self-grinding Sharp blades to achieve ideal result of crushing and returning straws to fields.
5. Specially developed chassis is proved durable after years of use.
