Overview of tools for large agricultural fields

The applied chassis system with a suspension system enables the connection of two 4.0 m wide cultivation machines, facilitating effective use based on needs. For instance, a machine produced in combination with a disc harrow can be transformed into a unit for pre-sowing cultivation by disconnecting the two 4.0 m machines purchased with the device from the tool carrier and connecting other cultivation machines. This versatility avoids costs associated with multiple purchases of the chassis, brake system, and hydraulic folding system for transport. Additionally, any mounted 4.0 m cultivation machine can be used with smaller tractors without utilizing the chassis with the suspension system.

Modular system for integrating machines onto a single chassis

The BigField machine comprises a chassis with a tool connection system and two 4.0m wide mounted units. It features two hydraulic suspension systems, enabling compatibility with various cultivation machines:
- Compact seedbed cultivator U 684
- Disc harrow U 652
- Universal cultivator U 497
- Compact disc harrow U 693
- Heavy stubble harrow U 671

Large working width enhances work efficiency

Two disc harrows or cultivators can be mounted on the same implement carrier using the three-point linkage. This multiple use of one carrier saves money, eliminating the need for double or triple investments in the chassis, brake system, and hydraulic folding device. In extremely challenging conditions, the chassis can be raised to utilize its full weight, thereby applying sufficient pressure on the soil through the working elements of the attached machines. During transport between fields, the device hydraulically folds the side sections of the machines, reducing the transport width to 3.0 meters, ensuring a smooth and safe ride. The transport system features a frame construction and is attached to the lower eyelet.

Machine construction

1. Drawbar hitch

The BigField system carrier is connected to the agricultural tractor via a Scharmüller drawbar eye on the transport hitch.

2. LED transport lighting

LED lighting positioned for field work duration.

3. Radial tires

The transport system features high-capacity 560/45R22.5 wheels. The radial tire construction ensures greater durability.

4. Large central piston

During operation, during turning, it enables the rapid lifting of both aggregated machines and is the most critical component of the hydraulic system when folding and unfolding the machine.

5. Three-point linkage

Three attachment points for accompanying machines are prepared for coupling with tractor hitch category III compliant machines. The robust suspension system can easily lift any 4.0 m wide cultivation machine.

6. Hydraulic accumulator

A hydraulic accumulator enables improved alignment of aggregated machines to the terrain's contour. When encountering a significant obstacle, the entire agricultural machine can elevate, safeguarding the device from damage.

7. Two brake variants

A pneumatic or hydraulic brake is integrated into the machine.

8. The full range of machines

The BigField system carrier is prepared for coupling with disc harrows and cultivators from the Rolmako range.

9. Quality steel

Achieving a high-quality final product necessitates the use of superior metallurgical materials; therefore, in manufacturing the agricultural machine frame, we utilize fine-grained Swedish steels S500MC and S700MC. The use of these high-quality steel products ensures our agricultural equipment is highly durable and capable of operating at high speeds with high surface efficiency.
