The NEXAT concept is based on a gantry-style carrier vehicle that spans the full working width of the crop area. Instead of multiple machines driving across the field, a single platform performs all operations by switching modules.

The system operates under a controlled traffic farming (CTF) approach:

• All wheels run on permanent lanes

• The crop area remains untouched by traffic

• Field operations are executed across the entire working width in one pass

This architecture fundamentally changes how mechanical loads are distributed in the field.

Structural Platform and Mobility

The core of the system is a self-propelled wide-span chassis supported by multiple large wheel units.

Key functional elements:

• High ground clearance: allows operation above growing crops

• Multiple steering modes: including crab steering for alignment with traffic lanes

• Load distribution: weight is spread across several wheels, reducing ground pressure

• Full-width coverage: the machine operates across the entire crop bed between traffic lanes

Because the platform spans the field, no part of the crop zone is driven over, which is central to the system’s agronomic concept.

Power and Energy Architecture

The NEXAT platform uses a diesel-electric power system.

How it works:

1. A diesel engine drives generators

2. Electrical power is distributed to: Wheel drive motors and implement modules

3. Each module receives energy as needed, independent of mechanical linkages

Functional implications:

• Eliminates complex mechanical drivetrains

• Enables precise power control per subsystem

• Simplifies integration of different modules

This architecture is critical for enabling fast switching between operations without mechanical reconfiguration.

Implement Carrier and Module Integration

The platform functions as a universal implement carrier.

Integration concept:

• Modules are mounted within the central frame

• Power, control, and data connections are standardized

• Swapping modules converts the machine into a different operation unit

Typical modules include:

• Seeding systems

• Crop protection sprayers

• Tillage tools

• Harvesting units

The machine itself remains the same; functionality is defined by the installed module.

Harvesting Module: Integrated Combine Function

One of the most distinctive modules is the harvesting system, developed in partnership with NEXCO.

Operating sequence:

1. Crop is cut across the full working width

2. Material is fed into a centralized threshing and separation system

3. Grain is cleaned and conveyed internally

4. Grain is transferred via an integrated system to transport units moving alongside

Key differences vs conventional combines:

• No onboard grain tank limitation in the traditional sense

• Continuous unloading reduces interruptions

• Extremely wide working width reduces passes

The harvesting process is integrated into the platform rather than being a standalone machine.

Automation and Control

The NEXAT system is designed for high-level automation, including autonomous operation.

Core control features:

• GPS-based guidance

• Predefined field paths aligned with traffic lanes

• Automated module control depending on operation

• Centralized system monitoring

Because all operations are executed by the same platform, data consistency across tasks is improved compared to multi-machine fleets.

Field Operation Logic

At the field level, the system operates as a single-machine production cycle:

1. The platform enters the field on fixed traffic lanes

2. A module is installed depending on the task (e.g., seeding)

3. The machine covers the entire width in sequential passes

4. The module is replaced for the next operation (e.g., spraying or harvesting)

This eliminates variability between machines and operators, standardizing execution.

Operational Implications

The NEXAT system changes the traditional machinery model in several ways:

• Reduces soil compaction by confining traffic to fixed lanes

• Minimizes fleet size, replacing multiple machines with one platform

• Increases working width, reducing time per operation

• Improves process integration, as all tasks share the same system

Analytical Conclusion

The NEXAT platform represents a shift from machine-based farming to system-based farming. Its functionality is not defined by a single operation, but by its ability to integrate all field processes into one controlled platform.

From a technical perspective, the key innovation lies in combining:

• Wide-span structural design

• Diesel-electric power distribution

• Modular implement integration

• Controlled traffic farming principles

This convergence positions the system as an alternative architecture to conventional multi-machine operations, particularly in large-scale, highly optimized farming environments.
