A combine harvester is a machine used to harvest grains, beans, and other crops. It integrates the harvesting, threshing, cleaning, and loading processes into one step, greatly improving the efficiency of the operation. Here are some of the main features and functions of a combine harvester:

### Main functions and features:

1. **Harvesting**:
- The stalks of the crop are cut using a front header (knife). The header is usually equipped with a rotating blade that can effectively harvest crops of various heights.

2. **Threshing**:
- The cut crops enter the threshing system, where the grains are usually separated from the rice ears or pods by a rotating thresher. The threshing process ensures that the grains are separated from impurities.

3. **Cleaning**:
- The threshed grains are further cleaned by a fan and screen system to remove residual straw, leaves, and impurities to ensure clean grains.

4. **Loading**:
- The cleaned grain is transported to the bucket through the conveying system for storage, and finally the grain can be loaded into a transport vehicle or other container through the unloading device.

5. **Driving and Control**:
- Modern combine harvesters are equipped with advanced cabs and control systems, which allow operators to conveniently control various functions of the harvester, including speed, header height and threshing intensity.

6. **Power System**:
- Combine harvesters are equipped with powerful engines to provide sufficient power to drive various systems and perform various functions. The power and efficiency of the engine are important factors in determining the performance of the harvester.

7. **Adaptability**:
- Modern combine harvesters are usually equipped with adjustable headers and adapters, which can adapt to different types of crops (such as wheat, corn, soybeans, etc.) and different working environments.

8. **Automation Function**:
- Some high-end combine harvesters are equipped with automatic navigation systems, automatic adjustment functions and data recording systems to help improve operation accuracy and efficiency and reduce manual intervention.

### Well-known brands:

- **John Deere**: A world-renowned agricultural machinery manufacturer that offers a wide range of combine harvesters.
