The 4UM-2 potato harvester features a full-hung double/triple lift chain structure, designed for use with wheel tractors equipped with 120-180 horsepower, hydraulic lift, and rear power output. It can complete tasks such as contouring, digging, cutting, separating, lifting, and laying out rows in one pass. It is suitable for harvesting needs in heavy clay, calcareous soil, and sandy loam regions with soil moisture content below 25%. It boasts a compact structure, high emergence rate, minimal tuber damage, safety, reliability, and high work efficiency.

Product Features:

The entire machine frame is made of high-strength plates, ensuring high strength. The widened frame structure increases the width of the dust-shedding chain, resulting in improved soil screening effectiveness.

2. The lifting chain drive is powered by wear-resistant rubber wheels, featuring low noise and overload protection. It also enhances the cleaning process, thereby improving the yield of clean potatoes.

3. Wider profiling mechanism design for easy adjustment, better imitating the ridge shape for smoother soil topping; it not only crushes the hard crust on the ridge surface but also ensures the depth of the digging blade, fully harvesting potatoes without damaging them, while reducing power consumption.

4. Equipped with imported circular cutting blades, it efficiently and promptly cuts potato stems and other weeds, preventing accumulation. It boasts a long service life, reliable performance, and stable operation.

5. Fully independent transmission structure; failure does not affect normal harvesting operations.

6. The秧轮 and frame inner wall are structurally compact, enhancing the soil intake volume.

7. The front potato board features an elastic connection, preventing soil and seedlings from blocking.

8. Extended rear shaking soil chain for better separation of potatoes from soil; reduced slope angle, solves the issue of skin damage from potato rollback.

9. Ultra-low sowing distance minimizes collision issues during potato fall, further reducing the skinning rate of potatoes.

10. Added mechanical soil roller; the roller compacts loose soil, increasing the yield of clear potatoes and making it easier for workers to pick them up.
