4U-170B-Moving blade and disc harvester

 Advanced Engineering Highlights 

1. Modular Combination Digging System

The standout feature of the 4U-170B is its modular digging assembly. Unlike standard fixed shovels, this system allows for the replacement of individual components.

• Adaptability: The entry angle can be fine-tuned to reduce "soil bulldozing" in heavy clay or to increase lift in loose, sandy conditions.

• Cost-Efficiency: When wear occurs, you only replace the specific shovel modules rather than the entire digging unit, significantly lowering long-term maintenance costs.

2. Maximum Filtration Length (3.81 Meters)

The 4U-170B features the longest frame in its class. The extended 3.8-meter conveyor path provides the tubers with more "tumble time" on the vibrating grid.

• Why it matters: In regions with high soil moisture or clod-heavy earth (common in parts of Russia and Northern Europe), the extra length ensures that potatoes are nearly $100\%$ free of soil by the time they reach the discharge point.

3. Intelligent Pressure Distribution

The frame is engineered with a specific center of gravity that balances the weight across the tractor's three-point linkage. This reduces the "nose-heavy" effect during transport and ensures that the depth-limiting wheels maintain constant contact with the soil surface for perfectly uniform digging.

4. High-Efficiency Separation Grid

The chain-link grid is manufactured from high-tensile, abrasion-resistant steel. The spacing is precision-engineered to maximize soil dropout while preventing smaller "baby potatoes" from falling through, ensuring your yield is maximized across all size grades.

 Application Environments & Global Utility

The 4U-170B is a high-performance export model, currently serving large-scale agricultural operators in North America, Bulgaria, and the Middle East.

• Large-Scale Potato Farms: Ideal for high-density planting of processing potatoes.

• Garlic & Onion Operations: The modular shovel can be adjusted for shallow, wide-sweep harvesting of delicate bulbs.

• Sweet Potato & Root Crop Recovery: The extended conveyor handles the larger volume of biomass associated with high-yield sweet potato fields without clogging.

Commercial & Logistics Strategy

• Quality Assurance: Every 4U-170B undergoes a multi-point shop inspection at our Qingdao facility, adhering to the same rigorous quality protocols we apply to our Samsung shipbuilding projects.

• Optimized Shipping: We utilize professional SKD (Semi-Knockdown) packaging. Despite its 3.8m length, we ensure components are packed to maximize container volume, reducing landed costs for international distributors.

• Global Compatibility: The PTO and linkage systems are built to ISO standards, ensuring immediate "plug-and-play" compatibility with John Deere, Case, and Massey Ferguson tractors.
