- The spray bar frame structure is stable and rigid, equipped with a four-bar linkage shock absorber to ensure even and stable spraying
- Hydraulic control of the folding and extension of the spray bar, capable of independently controlling each section of the spray bar
- The nozzle spacing is 50cm, and each nozzle can be independently controlled
- Hydraulic adjustment of the height of the spray bar above the ground
- Hydraulic adjustment of the inclination angle between the spray bar and the ground
- Driving wheel 18.4 R38
- The medicine box is made of polyester, with a smooth interior that is easy to mix and clean

The semi-automatic tracking tractor allows the machine to travel along the tractor's track. The swing angle of the traction frame is controlled and adjusted by sensors and oil cylinders

Hydraulic control of the folding and extension of the spray bar allows for independent control of each section of the spray bar. The width of the spray bar is reduced, making it easier to avoid obstacles during spraying

By remotely controlling the spray bar operation through sensors, the tilt angle between the spray bar and the ground and the height of the spray bar above the ground are automatically maintained during the working process, improving the accuracy and uniformity of spraying
