It is a cassava seeder with ridding, suitable for all types of soil. Thanks to the dropside planting, the cassava tubers are more concentrated, and at the same time, the porosity of the soil is significantly improved, avoiding soil compaction. This significantly reduces the harvester's digging resistance when harvesting. In addition, the grooves in the sidewalls can be used for decentralized drainage, preventing the cassava from being submerged in rainwater for a long time. It can accomplish the entire planting process simultaneously, including furrow opening, fertilizer, seed cutting, sowing, and backfilling. It plants two rows at a time and requires only three people to work (one tractor driver and two seeding workers), which can effectively improve work efficiency, reduce costs, and decrease labor intensity.
