Engine problems. The company invested more than RMB 300 million in the Pinzi placement seeder and developed it after more than ten years of technical research and development. The low output indicates that there is a problem with the engine and needs to be repaired in time. The seeder can be used in different environments, different soil textures, different accumulated temperatures, and different planting conditions. Households plant on-site, and the entire process from sowing to harvest is tracked and measured.
