This 4U product offers excellent performance and high efficiency, primarily used for harvesting underground root crops such as potatoes, garlic, sweet potatoes, carrots, and peanuts. It features high harvesting efficiency, low breakage, fast, vibration-free operation, resistance to weed clogging, simple structure, rapid soil removal, and a long service life. This machine has been granted both utility model and design patents by the State Intellectual Property Office.
4U Potato harvester operates quickly, allows for centralized stacking, saves labor, and reduces air leakage.
4U series Potato Harvester is paired with a 20-100hp tractor through rear horsepower or side horsepower transmission. it is used for digging potatoes, separating the tubers from the soil, allowing the potatoes to detach from the roots and reach the ground for easy picking.
Equipped with a triangular mixer. Under the PTO transmission of the tractor, the soil and tubers are separated by the vibration of the vibrating screen.
The soil falls out in the gap of the vibrating screen, and the potatoes left on the vibrating screen fall to the land behind through the vibration of the vibrating screen.

01
Adjustable digging depth
Adjust the digging depth (generally 5-10cm deeper than the rhizome), travel speed (faster in sandy soil, slower in clay soil), and vibration frequency (to avoid damage caused by excessive vibration) according to the crop variety (such as potato size and carrot length) and soil conditions (clay/sandy soil).
02
Fan screening device on harvester
The fan on the harvester blows away light impurities (such as fine soil and dead leaves), or uses a screening device to remove oversized/undersized defective products and retain qualified rhizomes.
Weaken the fan force during cleaning (to avoid blowing off the outer skin).
03
Separate the rhizomes from the attached soil and straw
Use a vibrating screen, conveyor belt or tooth structure to separate the roots and attached soil and straw (such as garlic leaves and carrot tops).
The conveyor belt is made of soft material (such as rubber) to reduce friction damage.
04
Blades and coulters inserted into the soil to loosen
The harvester inserts blades and plow blades into the soil, loosening the soil around the plant's roots and lifting the entire plant (including the rhizome) out of the soil. The harvester then transports the entire plant (including the rhizome) to a collection bin (or directly bags or boxes) for easy transportation and processing.

Agriculture Cassava Harvester Double Row Potato Harvester
Sweet Potato Harvester / Potato Harvester
Potato harvesters, used in conjunction with small four-wheel tractors, are primarily used for harvesting and stacking underground tubers such as sweet potatoes and potatoes.
They achieve a clean potato yield exceeding 99% and a breakage rate of less than 1%. Both sweet potato and potato harvesters are safe, simple, easy to operate, flexible, aesthetically pleasing, and durable.
potato harvester
The potato harvester can be driven by tractors with power ranging from 20 to 80 horsepower, making it suitable for the four-wheel tractors currently owned by most farmers. It offers a wide power range, low investment, and rapid results.

Used to harvest underground stems of crops such as potatoes, garlic, sweet potatoes, and peanuts.
Our range of potato planters and harvesters is designed to revolutionise potato farming with precision planting and efficient harvesting solutions. Whether you're a small-scale grower or managing a large farm, our machines offer unrivalled performance, increasing productivity while ensuring a well-cared-for and high-quality crop.
Increased Efficiency for Small-Scale Farming: Small potato harvesters are designed for small fields and gardens where large industrial harvesters are inadequate. They significantly reduce the manual labor required for potato harvesting.
Enhanced Soil Management: Some small harvesters are designed to loosen the soil during harvest, improving soil aeration and preparing it for future planting.

Onions, garlic, potatoes, and carrots are all underground root crops, and their harvesting requires a series of steps: digging, separating, cleaning, and collecting. Specialized harvesters for these crops significantly improve harvesting efficiency and crop integrity by integrating mechanical structure and intelligent control.
We specialize in the research and development of potato harvesting machinery. Our mounted potato harvester utilizes advanced digging and separation technology, enabling adjustable row spacing. It can perform operations such as separating potatoes from soil, separating potato vines, and laying out tubers in strips. It boasts a high rate of clear potatoes and low rates of damaged or broken potatoes. It can be used for harvesting carrots, onions, parsnips, beets, and celery.
The separator has undergone significant improvements, effectively separating impurities and is suitable for domestic potato growers.
The machine's powerful power system ensures long-term, stable operation with minimal crop damage, making it suitable for large-scale growers and farms.
