2. EP-CT-2100 Rock Picker Overview
South Korea’s agricultural landscape is characterized by mountainous terrain and granite-rich soils, presenting unique challenges for modern farming and land cultivation. The Watanabe CT-2100 stone collector is more than just a machine; it’s a strategic engineering solution designed to address these demanding conditions.
Unlike conventional equipment that often fails under the pressure of heavy basalt or granite rocks common in regions like Gangwon-do or Gyeongsangbuk-do, the CT-2100 features a robust hydraulic drive system specifically calibrated for high performance and durability.
The machine is designed to systematically remove stones from fields that can damage harvesting equipment, hinder the root growth of high-value crops like ginseng and potatoes, and reduce the overall value of the land. Integrating the CT-2100 into your workflow means not only clearing debris but fundamentally transforming soil structure to meet the standards of precision agriculture. The machine’s design emphasizes longevity and reduced downtime, ensuring that critical spring planting operations are not interrupted by the mechanical failures common with inferior stone collectors.
Furthermore, the CT-2100’s application perfectly aligns with the growing trend of mechanization efficiency in East Asia. With increasing labor shortages in rural South Korea, relying on manual stone picking is no longer economically viable. The CT-2100’s 1.95-meter working width allows for rapid coverage of large areas in a single pass. This efficiency is crucial for preparing land for specialized crops that require deep, stone-free soil for optimal tuber expansion or root penetration. When used in conjunction with power stone collectors or landscape rakes for initial piling, the CT-2100 acts as the final collection unit, gathering the piled debris with high precision. The Category 2 three-point hitch design ensures stability on uneven terrain.
3. Working Principle, Metallurgy & Application Scenarios
3.1. Advanced Hydraulic Picking Mechanism
The Watanabe CT-2100 operates on a sophisticated hydraulic-driven rotary principle. Unlike a static rock rake for skid steer which drags debris, the CT-2100 actively lifts. As the tractor moves forward, the heavy-duty tines dig slightly into the soil surface. The hydraulic reel, powered by the tractor’s 60 L/min oil flow, sweeps stones onto a screening grate. The soil falls back through the grate while the stones are conveyed into the expansive 2.5 m³ rear bunker. This active separation ensures that topsoil retention is maximized—a critical factor for sustainable farming in regions with thin topsoil layers. The high dumping height allows for easy offloading into trucks or piles at the field edge.
3.2. Material Composition & Durability
Durability is paramount when dealing with abrasive lithology. The mainframe of the CT-2100 is constructed from high-tensile structural steel (comparable to Q345B or S355), providing the necessary rigidity to withstand torsion on uneven ground. The pick-up tines and the screening grate are manufactured using heat-treated, wear-resistant alloy steel (typically manganese or boron steel derivatives), offering a hardness rating often exceeding 45-50 HRC. This ensures that even after hundreds of hours of contact with abrasive silica-rich rocks, the wear components maintain their structural integrity. This is a significant upgrade over a standard small rock rake or gravel rake often found in residential gardening, which utilizes milder steels unsuited for agricultural-scale operations.
3.3.Synergy with Rock Rake Attachments
While the CT-2100 is a powerhouse collector, its efficiency is doubled when paired with a rock rake attachment. In a typical workflow, a farmer would first use a rock rake for tractor or a rotary landscape rake to windrow scattered surface stones into neat lines. Once windrowed, the CT-2100 follows the line, picking up the concentrated volume of stone. This two-step process reduces the number of passes required by the heavy picker, saving fuel and reducing soil compaction. For smaller operations or tight corners where the CT-2100 cannot reach, a rock rake for atv or a rock rake hand tool might be used for spot cleaning, ensuring comprehensive field management.
4. Global Trends & Regulatory Compliance
Regulatory Landscape: In South Korea, the Farmland Act emphasizes the preservation of soil productivity and the prevention of land degradation. Excessive stoniness is classified as a hindrance to mechanization, often requiring remediation to qualify for certain agricultural subsidies or to maintain land value classifications. Furthermore, in construction projects involving land reclamation, strict regulations govern the disposal of excavated rock and soil separation. The CT-2100 facilitates compliance by efficiently separating rock (which can be crushed and repurposed as aggregate) from soil, adhering to resource recycling mandates. Similarly, in markets like Europe and North America, soil conservation laws (such as cross-compliance rules in the CAP) mandate minimizing soil erosion; the CT-2100’s ability to pick stones without stripping vegetation cover or topsoil aligns perfectly with these environmental standards.
Market Trends: The global trend in stone management is shifting towards “Precision Land Reclamation.” Operators are moving away from simple burial or manual removal towards mechanical harvesting of rock for crushing. The demand for rock rake machines and pickers is rising in correlation with the adoption of precision seeders, which have zero tolerance for stone impact. There is also a growing trend in the “rental economy” for such specialized equipment. In South Korea, agricultural machinery rental banks are increasingly stocking heavy-duty pickers like the CT-2100 to serve multiple small-hold farmers who cannot justify the purchase of a rock rake attachment or picker individually. This shared-economy model demands equipment with extreme durability and low maintenance requirements—core attributes of the Watanabe engineering philosophy.
