The 4U-170 is the heavyweight champion of our potato harvester series, designed specifically for high-intensity agricultural projects and large-scale commercial farming. With a massive 1700mm working width and a robust frame, this model is engineered to handle the demands of 120HP+ tractors, delivering unparalleled productivity in the field.
The 4U-170 is built for speed and volume. The 1.7-meter wide throat allows it to process significant amounts of soil and crop simultaneously. When paired with a 120-150 HP tractor, this machine can cover massive acreage in a fraction of the time compared to standard models, making it the preferred choice for industrial agricultural cooperatives.
Unlike smaller models, the 4U-170 utilizes a reinforced fixed flat shovel. This design is specifically chosen for high-power applications where soil might be more compacted or heavy. The fixed shovel provides the stability needed to maintain a consistent cut at high ground speeds without the mechanical wear associated with vibration in ultra-wide frames.
With an overall length of 3.38 meters, the 4U-170 features an extended conveyor and sieving system. This longer travel path ensures:
Superior Soil Cleaning: Even in damp or sticky soil conditions, the extra travel time allows for better agitation and soil dropout.
Neat Windrowing: Crops are discharged at the rear in a precise, clean row, facilitating easier mechanical loading or manual collection.
The chassis is constructed from high-grade structural steel to withstand the torsional stress of a 1.7-meter wide harvest. The transmission system is reinforced to handle the high torque output of 100kW+tractor engines, ensuring long-term reliability in the most demanding environments.
The 4U-170 is a global performer, widely exported to regions with large-scale agricultural infrastructure like Russia, North America, Kazakhstan, and Australia. It is highly effective for:
Industrial Potatoes: Perfect for starch and chip-processing varieties.
Large-Scale Garlic & Onion Farms: Handles high volumes with minimal bulb damage.
Root-Based Herbs: Robust enough for deep-digging medicinal roots in varied soil profiles.
Container Optimization: Despite its size, the 4U-170 is designed for efficient shipping. We offer semi-knockdown (SKD) packing to ensure you get the best freight rates per unit.
Precision Engineering: Every unit undergoes a rigorous shop inspection—meeting the same high standards we apply to our large-scale industrial shipbuilding projects and energy station equipment.
Global Support: We provide a comprehensive spare parts package, including high-wear items like shovel tips and chain links, to minimize downtime during the peak harvest season.
