4U-180 Potato Harvester delivers large-area field performance with reinforced digging and multi-row disc systems. Built for intensive potato cultivation, this harvester maintains tuber integrity while streamlining workflow and maximizing harvesting output. Moving blade and disc harvester The new moving blade and disc harvester is a harvesting machine produced according to the characteristics of some areas where the seedlings are not killed and the soil is hard. The cutting disc can cut off some seedlings to prevent entanglement and prevent the potatoes and fruits from being scattered and crushed. The moving blade can easily enter the ground to reduce power and increase the soil crushing function to make the harvesting effect better and more efficient. The models are 0.7m-1.5m.
