Soybeans, Models :Q20BCX-JP / Q26BCX-JP

Designed for improved adaptability in delicate soybean harvesting environments, delivering stable performance even under low cutting heights prone to soil intake

When harvesting wheat, buckwheat, and similar crops, install the bottom plates on the platform and the feeder house to prevent harvested crops from leaking.

Platform bottom soil holes, Feeder house bottom soil holes

Ensures sufficient airflow even during soybean harvesting under poor working conditions.

Keeps the cutter unit perfectly aligned with the ridges, ensuring clean and stable cutting even across varying ridge heights and sloped terrain.

Ensures stable cutting height even in uneven field conditions.

The working speed increases, and the number of turns is reduced, enabling more efficient harvesting.

Wide Header:2590 mm (Q26BX-JP / Q26BCX-JP), 2060mm (Q20BX-JP / Q20BCX-JP),Working Speed: 1.15 m/s

The engine maintains a constant speed, reducing unnecessary fluctuations in rotation.

The DPF reduces PM (particulate matter) in exhaust gas. When PM accumulates, the DPF automatically regenerates, minimizing the need for manual intervention.

Maximum Output: 68.6 PS, Total Displacement 3.318 L

The compact design allows smooth operation even in narrow fields.

In addition to the “Long Rotor,” a “Front Rotor” is installed.
Combined with the wide “Large Agitation Separation Plate,” these three mechanisms enable smooth and efficient threshing and separation.

❶ Rotor Speed Change Lever
Allows easy adjustment of rotor speed to match crop conditions.

❷ Front Rotor
Performs pre-threshing and separation before the main rotor,reducing load and improving efficiency.

❸ Pre-Fan + ❹ Winnowing Fan + ❺ Second Fan
Triple Fan

The three fans provide stable separation across the entire area even during high-flow operations, enabling highly accurate separation.

❻ Large Swing Separator
With a wide surface area, it provides ample capacity, allowing efficient and highly accurate separation even when a large amount of grain enters during high-speed operation.
Surface Area: 1.2 m2

❼ Large Concave
Provides a wide area for effective threshing and separation.
Area: 1.75 m2

❽ Long Rotor
The long rotor gently threshes for an extended time, reducing unthreshed grains and minimizing damage to the grains.
Diamter: 495mm
Length: 1850mm
Tip of the tooth bar: 640mm (wheat)、625mm (soybean)

❾ Bucket Elevator

Even in large fields, fewer discharges are required, allowing for extended continuous operation. High-speed grain discharge is also possible, contributing to improved work efficiency.

Capacity: 1600 L, Discharge Time: Approx 155 Sec.(for wheat)

The auger can be easily set with the push of a button, and stored with one touch. This reduces time loss during operation

  • Manual setting and storage are also possible
  • Two-stage grain tank level sensors allow operators to easily monitor fill status during operation.

    Convenient for knowing the optimal timing for discharge!
    Always drive with both crawlers moving. Keeps the inner crawler moving during turns to prevent sinking

    With light and effortless steering, the machine delivers optimal turning performance in every condition.
    Even during turns, both crawlers remain fully driven, ensuring smooth maneuvering when crossing levees or working in uneven fields. This provides exceptionally smooth harvesting with reduced operator fatigue.

    Compared to operating with a single lever for left and right directions, you can work comfortably with less strain.
    Even during long hours of operation, physical fatigue is reduced, making work easier.

    ① Gentle Turn
    Reduce the speed of the inner crawler for a smooth turn.
    The turning radius can be adjusted according to the steering angle of the handle.

    Forward [Medium], Forward [High]

    ② Brake Turn
    Stop the inner crawler and rotate using only the outer crawler.
    Useful for turning in tight spots.

    Stop – Forward [High]

    ③ Spin Turn
    Rotate the inner crawler backward for a sharp turn.
    Makes entry into adjacent rows easier.

    Forward [High], Backward [Medium]

    ④ Left-Right Micro Adjustment
    Rotate the inner crawler backward for a sharp turn.
    Makes entry into adjacent rows easier.

    Forward [Low], Forward [Medium]

    ”Machine Leveling Control" senses the undulations of the field and raises and lowers the left and right crawlers to maintain a level surface.
    "Ground Parallel Control" keeps the harvesting unit parallel to the ridges, even on slopes or ridges of varying heights, such as in soybeans.

    By switching between two automatic control modes to prevent soil from being drawn in, ensuring stable and reliable harvesting.
    Manual operation is also available.

    Automatic Machine Leveling
, Ground‑Following Control
    Automatic Raise, Automatic Fall

    Sensors mounted on the bottom of the platform, divided into left and right, detect unevenness in the field and maintain cutting at a constant height.

    Cutting Height Sensor
    Cutting Height Adjustment Lever

    Protects the operator from dust and debris, ensuring a clean and comfortable workspace at all times. Plus, the multi-function shift lever enhances operability for smoother, more efficient control.
