[0002] Seeder is an important agricultural machinery equipment, mainly used to spread seeds evenly into the land to improve planting efficiency and crop yield. Seeders come in many types and styles, suitable for different regions and planting needs.

[0003] Seeders are mainly divided into two types: direct seeding and transplanting. Direct seeding seeders are usually used to sow small seeds, such as wheat, corn, rice, etc.; transplanting seeders are suitable for sowing large seeds, such as beans, sunflowers, etc. In addition, according to different uses and places of use, seeders can also be divided into hand-push type, tractor-mounted type and self-propelled type.
