Features of seeding roll
- 1/2/3 row types and zig zag processing (special roll & coating seeding roll)
- Electrostatic-handling processed
- CNC (there-dimensional precision processing)

Choosing a roll based on a hopper cover
Pour some seeds into a cover, spread them evenly and choose a suitable groove standard.
Development of seeding roll made of electrostatic handling material
Seeding roll > Discharge of seeds (blocking a brush) >
Discharge of static electricity (discharged to the ground though a plough) > Accurate amount of and distance between seeds
| Conductivity test (discharge of static electricity) | Constant temperature heat treatment (stress removal in the rainy season) |
