Lightweight Pneumatic Seeding for Small and Low-Power Tractors
The YongXiang 2BFGL-A Series is a lightweight pneumatic seeder designed for small and low-power tractors. Its compact structure combines pneumatic seed metering and delivery with a parallel four-bar linkage and packer roller for controlled seed placement and soil reconsolidation.
With adjustable outlets, interchangeable metering shafts, radar speed synchronisation and one-touch calibration, the 2BFGL-A Series provides a practical solution for accurate seeding across different crops, row spacings and field conditions.

Key Benefits
Designed for small and low-power tractors from 60–80 HP.
Helps each seeding unit follow changes in ground contour for more consistent seed placement.
Delivers metered seed through flexible seed hoses to the selected outlets.
The packer roller firms the worked soil and helps create suitable conditions for seed establishment.
Adjusts metering according to forward speed to help maintain the selected application rate.
Adjustable outlets and interchangeable metering shafts allow the machine to be adapted to different crops and seeding requirements.
Lightweight Configuration for Low-Power Tractors The 2BFGL-A Series is designed as a compact, lightweight pneumatic seeder for tractors from 60–80 HP.
Its relatively low-power requirement makes it suitable for smaller farms, compact tractors and operations where a lightweight mounted seeder is preferred.
The machine integrates seed metering, pneumatic delivery, furrow opening, seed covering and soil reconsolidation.
Parallel Four-Bar Linkage for Ground Following
The parallel four-bar linkage allows the seeding units to move independently with changes in ground contour.
This helps maintain a more consistent relationship between the coulter and soil surface across uneven terrain, supporting uniform seed placement and emergence.
The linkage also allows the seeding units to follow the ground independently rather than relying solely on the main machine frame.
Packer Roller for Soil Reconsolidation
The packer roller reconsolidates the worked soil after seed placement and helps close and firm the seedbed surface.
Controlled reconsolidation improves soil-to-seed contact and creates a more stable surface for crop establishment.
The roller also helps maintain a consistent seedbed structure behind the seeding units.

Interchangeable Metering Shafts
Different metering shafts are available for different seed types, seed sizes and application rates.
The correct shaft selection helps maintain consistent material delivery, particularly when working with small seeds or lower application rates.
The shaft can be changed without specialist tools to adapt the machine to different crops and compatible materials.
The 10-inch control console allows the operator to monitor and adjust key seeding parameters from the tractor cab.
The system provides access to application-rate settings, calibration functions and hopper-level information.
The calibration function allows the selected application rate to be checked and adjusted before field operation.
The selected metering shaft and its rotational speed determine the application rate.
The metering system uses an electric drive controlled by the central control system. The metering speed is adjusted according to the selected application rate and forward speed.
This speed-responsive control helps maintain consistent material delivery as field speed changes.
12V electric fans generate the airflow required to transport metered seed through the seed lines to the distribution outlets.
The pneumatic delivery system provides an even flow of material across the working width. Protective mesh at the fan air intakes helps prevent straw and debris from entering the fan system.
The radar sensor continuously measures forward speed and sends the speed signal to the control system.
The metering drive responds to changes in forward speed to help maintain the selected application rate.
Optional Seed Tube Blockage Monitoring
Optional seed tube blockage monitoring detects interruptions in material flow through the seed tubes.
Sensors monitor material flow and provide an alert on the control terminal if a blockage or missed delivery is detected.
An agitator positioned above the metering shaft helps maintain consistent material flow and reduce the risk of bridging.
A low-level hopper sensor provides an alarm when the material level falls below the set threshold.
Flexible Outlet Configuration
Each outlet can be opened or closed independently using the supplied L-shaped plugs.
This allows the number of active outlets to be matched to the required working width and row configuration.
The lift switch kit automatically stops metering when the implement is raised and resumes metering when the implement is lowered again.
This provides automatic start/stop control during headland turns, transport and other raised-implement operations.
Optional GPS Speed and Positioning
An optional GPS sensor can provide the vehicle's speed signal to the control system for speed-responsive metering.GPS speed data can be used as an alternative to radar speed signal.
An optional GPS positioning chip can provide positioning information for monitoring the seeder's field trajectory.
GPS positioning functionality is currently under overseas testing and should therefore be regarded as an optional developing function rather than a fully established feature.
Real-Time Seeding Monitoring
An integrated camera allows the operator to monitor the seeding process from the control console.
This provides an additional visual check during operation and helps the operator monitor the working condition of the seeding system from the tractor cab.
Precision Row Drilling
The 2BFG-C Series can be configured for row drilling according to the selected outlet arrangement.
For row drilling, stainless-steel outlets can be fitted to the seed lines to deliver material through individual outlets.
This flexibility allows the seeding system to be adapted to different crops, working widths and application methods.
