Rotary Tillage Seeder and Fertilizer Applicator | 2BFG-A-F Series

 
Integrated Seeding and Fertilizer Application with Parallel Four-Bar Linkage
 
The YongXiang 2BFG-A-F Series combines fertilizer application, rotary tillage, seedbed consolidation, furrow opening, pneumatic seeding and soil covering in a single field operation.

The machine uses a 600-litre split hopper with two fixed, reverse-mounted metering systems, dedicated to simultaneous seed and fertilizer application. The two metering systems are integrated into the complete machine and operate independently according to their respective application rates.

The working structure is arranged from front to rear as fertilizer application, rotary tillage, compacting roller and parallel four-bar linkage seeding units.

The compacting roller consolidates the soil directly behind the rotary tiller, while the parallel four-bar linkage allows the seeding units to follow changes in ground contours. The double disc coulters then open the seed furrows and place seed at the selected depth.

Key Benefits



One-Pass Seedbed Preparation
Combines power harrow cultivation and pneumatic seeding in one operation.


600L Split Hopper
Provides flexible capacity for different material configurations.


Parallel Four-Bar Linkage
Helps the seeding units follow changes in ground contours.


Dual 12-Row Configuration

Supports simultaneous seeding and fertilizer application.


Independent Reconsolidation
Helps maintain consistent soil conditions after seeding.


Efficient Crop Establishment
Combines multiple field operations in a single pass.




One-Pass Seedbed Preparation and Seeding


1. Fertilizer Application

  Granular fertilizer is metered and distributed according to the selected application rate.

2. Rotary Tillage

  The rotary tillage unit prepares and loosens the soil.

3. Seedbed Consolidation

  The compacting roller, positioned behind the rotary tiller, consolidates the worked soil before the seeding units.

4. Furrow Opening

  The double disc coulters on the four-bar linkage seeding units open the seed furrows.

5. Pneumatic Seeding

  Metered seed is transported pneumatically through the seed lines to the seeding outlets.

6. Soil Covering

  The soil-covering components cover the seed furrows after seed placement.




600L Split Hopper with Fixed Dual Metering

600L Split Hopper with Fixed Dual Metering


The 600-litre split hopper is integrated into the complete machine and provides separate material compartments for seed and fertilizer.


The two metering systems are fixed in the machine's reverse-mounted configuration and are designed for simultaneous seed and fertilizer application.





Double Disc Coulter with Depth Control

Parallel Four-Bar Linkage Profiling


The parallel four-bar linkage connects the seeding units to the main machine and allows them to follow changes in ground contours.


This helps maintain a consistent working position of the seeding units across changing field conditions.

Compacting Roller Before the Four-Bar Seeding Units


The compacting roller is positioned directly behind the rotary tiller and ahead of the four-bar linkage seeding units.


It consolidates the freshly worked soil before furrow opening and seed placement.





Interchangeable Metering Roller

Dual Interchangeable Metering Systems


Different metering rollers can be selected according to seed type, fertilizer material, particle size and application rate.


The two metering systems operate independently, allowing seed and fertilizer to be applied simultaneously at their respective selected rates.







Intuitive Control and One-Touch Calibration Intuitive Control and One-Touch Calibration


The 10-inch touchscreen control terminal allows the operator to monitor and adjust key seeding and fertilizer application parameters from the tractor cab.


The control system provides access to application-rate settings, calibration functions and hopper-level information.


A dedicated calibration function allows the selected application rate to be checked and adjusted before field operation.





Consistent Metering with Electric Drive

Independent Electric Metering Control


The seed and fertilizer metering systems are driven and controlled independently.


The control system adjusts metering speed according to the selected application rate and forward speed, helping maintain consistent material delivery during operation.






Dual Pneumatic Seed Delivery

Dual Metering and Pneumatic Delivery


The two metering systems operate independently for seed and fertilizer application.


Pneumatic delivery transports the metered seed through the seed lines to the seeding outlets, while the fertilizer system delivers fertilizer through its corresponding distribution system.







Radar Speed Synchronisation Radar Speed Synchronisation


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, helping maintain the selected application rate when the tractor slows down or increases speed.


This speed-responsive control supports consistent material application across changing field conditions.




Optional Seed Tube Blockage Monitoring

Optional Seed Tube Blockage Monitoring for Two Monitoring Systems


Optional seed tube blockage monitoring detects interruptions in material flow through the seed tubes.


Sensors monitor material flow below the discharge points and provide an alert on the control terminal if a blockage or missed delivery is detected.


This gives the operator an additional check on seed delivery and helps identify problems quickly during operation.




Agitator and Hopper Level Monitoring Dual Agitator and Hopper Level Monitoring


Each hopper section is equipped with an agitator positioned above the metering system to help maintain consistent material flow.


A low-level hopper sensor provides an alarm when the material level falls below the critical threshold.









Flexible Outlet Configuration

Flexible Outlet Configuration


Individual outlets can be opened or closed using the supplied L-shaped plugs.


This allows the active outlets to be matched to the required working width and row configuration.








Lift Switch Kit Optional Lift Switch Kit


The optional lift switch kit automatically starts or stops metering according to the position of the implement.


When the implement is raised, the metering system stops automatically. When the implement is lowered again, metering resumes.


The stainless-steel switch is mounted on the tractor's three-point linkage and provides automatic start/stop control during headland turns, transport and other raised-implement operations.




GPS Speed and Positioning 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 presented as an optional developing function rather than a fully established feature.




Real-Time Seeding Monitoring 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 field operation.









Row seeding

Row Seeding


The pneumatic seeding system can be configured for row seeding according to the selected outlet arrangement.


For row seeding, stainless-steel outlets can be fitted to the seed lines to deliver material through individual outlets.
