Model 4BYQ-2.6 Front-Mounted Kidney Bean Puller | PTO Harvester

Equipment Overview & Agronomic Function

Harvesting edible dry beans presents a unique agronomic challenge. Unlike soybeans or wheat, kidney beans, navy beans, and black beans grow low to the ground with pods that become highly susceptible to shattering as they dry. Attempting to run a standard combine harvester directly through a standing field of dry beans often results in unacceptable yield losses, with shattered beans left to rot in the soil. To combat this, professional farming operations utilize a two-step harvesting method: pulling and windrowing, followed by threshing. The Model 4BYQ-2.6 serves as the critical first step in this process. As a highly specialized Front-Mounted Puller, it is engineered to gently uproot the bean plants, separate the root system from the soil clods, and lay the crop down in continuous, aerated windrows for natural field drying.

Operating across a generous 2.6-meter working width, this specific unit is calibrated to cover four standard planting rows in a single pass. By mounting to the front hydraulic linkage of the tractor rather than being towed behind, the equipment provides the operator with unobstructed forward visibility. This structural design prevents the tractor tires from running over and crushing standing crops prior to harvesting. The core mechanism relies on a heavy-duty rotary system that interacts with the soil surface, cutting the taproots just below the ground level while the mechanical pickup system lifts the foliage.

By mechanizing this inherently labor-intensive process, the 4BYQ-2.6 Kidney Bean Puller drastically reduces seasonal labor expenditures and compresses the harvesting window. This allows farm managers to beat adverse weather conditions, securing crop quality and maximizing the final tonnage delivered to the processing elevator. The robust 1100 kg structural mass ensures that the implement remains stable and engaged with the ground contour, maintaining a consistent cutting depth even when navigating uneven field topography or varying soil densities.

4BYQ-2.6 Kidney Bean Puller – Technical Specifications & Operational Metrics

Engineering Context: The parameters outlined above are carefully calculated to match standard agricultural practices. The matched power range of 66-88 kW (approximately 90-120 HP) ensures the tractor possesses adequate hydraulic lifting capacity and PTO torque to run the machine continuously through dense field conditions without engine strain. The 2600 mm wheel track aligns precisely with standard bean row spacing, preventing tire damage to adjacent unharvested rows. Furthermore, the 540 r/min PTO speed is the universal standard for mid-sized tractors, making this implement highly compatible with existing farm fleets globally.

4BYQ-2.6 Kidney Bean Puller Target Field Applications & Soil Adaptability

The 4BYQ-2.6 kidney bean puller is designed for broad-acre farming operations focused on large-scale legume production. Its primary application lies in the harvesting of dry edible beans—including kidney beans, pinto beans, great northern beans, and cranberry beans. These crops share similar morphological traits, specifically pod placement near the soil surface and a tendency for pods to split open upon harsh impact when dry. The machine operates with high efficiency on large flatlands, prairie soils, and gently undulating hills where a constant tractor speed can be maintained.

Soil conditions heavily dictate the success of mechanical harvesting. Standard light pullers often struggle in compact, hard earth, vibrating excessively or failing to penetrate the crust. To solve this, the 4BYQ-2.6 is explicitly engineered as a heavy duty kidney bean puller for clay soil. Its 1100 kg weight provides the necessary downward force to keep the cutting components securely positioned under the soil surface, cutting through thick clay clods without skipping or bouncing. Whether dealing with the loamy soils of the Midwest or the dense, moisture-retaining clay of coastal agricultural zones, the hardened steel tines strip dirt away from the root ball cleanly, ensuring the resulting windrow is free of excess earth that could later jam the combine thresher.

Manufacturing Capability & Supplier Reliability

Sourcing heavy machinery requires a partner with proven industrial capacity, not just a trading intermediary. As a premier Kidney Bean Puller Manufacturer, we operate a 25,000-square-meter modern production facility dedicated entirely to agricultural implements. Our manufacturing floor is equipped with CNC laser cutting machines and multi-axis machining centers, ensuring that every bracket, gearbox housing, and rotor shaft is manufactured to strict millimeter tolerances. This precision guarantees that replacement parts will fit perfectly years down the line.

Beyond physical manufacturing, we house an experienced technical engineering team that has spent decades analyzing harvest mechanics in different global soil zones. We don’t just sell equipment; we provide comprehensive solutions. When you place a bulk B2B order, our logistics team calculates optimal loading plans to maximize the number of units per 40HQ shipping container, reducing your landed cost. Furthermore, every machine undergoes rigorous dynamometer testing on the PTO drive and hydraulic pressure checks prior to crating, ensuring out-of-the-box readiness when the shipment arrives at your farm or dealership.

Preventative Maintenance Guidelines

To protect your investment and ensure maximum uptime during the short harvest window, adhering to a strict maintenance protocol is mandatory. The 4BYQ-2.6 is designed for straightforward field servicing. The primary PTO drive shaft features shear bolts designed to snap and protect the main gearbox if the rotor strikes an immovable object like a large boulder. Operators should keep spare shear bolts in the tractor cab at all times.

Daily checks involve inspecting the spring teeth for bent or missing tines, which can result in uneven windrow formation and left-behind crops. All grease zerks on the pivot points and bearing housings must be lubricated every 50 operating hours with high-temperature lithium grease to force out accumulated dirt and moisture. Additionally, gear oil levels in the central transmission box should be checked prior to the start of the harvest season and replaced after the first 100 hours of initial break-in operation to remove any microscopic metal shavings from the manufacturing process.
