When potatoes are harvested, the most heavy physical labor is realized, most farmers cannot harvest the potatoes in time due to the difficulty in digging, and the potatoes are frozen and rotted in the ground, so that the economic income is directly influenced; therefore, the small four-wheel potato harvester is a wish of common farmers, so far, the potato harvester with the small four-wheel is not ideal, and some potato harvesters have complex structure, inconvenient installation and large energy consumption; also, the breakage is large, and the net rate is low.
Especially, when harvesting, because the hilly terrain is more in China and the land is uneven, when harvesting is carried out in the environment, the digging depth is easily uneven, so that the potatoes are not harvested completely, even in some areas with large land fluctuation changes, the phenomenon of not digging can be caused, and the potatoes can not be harvested normally.
