The 2TD-S2 potato earthing-up machine can realize the earthing-up after the potatoes get film-coated. It is easy to operate and practical to use, with high efficiency and even earthing-up. Advantages: protecting potato sprouts from being burnt by sunlight, preventing weed-sprouting, avoiding “green potatoes” and ensuring vigorous sprouts.  The potato seedlings will come out through the plastic film, saving the labor force for film-breaking.
