The 4U-160 sweet potato harvester boasts high performance and efficiency. It is primarily used for harvesting sweet potatoes and other underground root and stem crops. Its features include high harvesting efficiency, minimal skin damage, ability to harvest with vines, smooth and vibration-free operation, no clogging, rapid soil discharge, simple structure, and long service life. It is a nationally patented product and a domestic innovation. Most importantly, our machinery can directly extract residual agricultural film from the soil, without affecting the growth of crops in the next season. It uses advanced national industrial cast-rubber rear drive wheels to reduce gear wear and extend lifespan.
