Kalverkamp has unveiled Nexat, a multi-function autonomous platform designed to perform multiple operations across the crop production cycle.

The system combines seeding, crop protection, fertilization and harvesting capabilities within a single machine architecture, targeting efficiency gains through full-field process integration.

Recognition at Agritechnica 2022

Although still in a prototype stage, Nexat received the Gold Medal at Agritechnica 2022, recognizing its innovation within the agricultural machinery sector.

The name Nexat is derived from “Next Generation Agricultural Technology,” reflecting its positioning as a new approach to field operations.

Multi-Function Concept

At its core, Nexat consists of an autonomous, electrically driven platform designed to operate with interchangeable modules depending on the task.

This architecture enables the machine to carry out multiple field operations using the same base unit, including:

• Seeding

• Spraying

• Fertilizer application

• Harvesting

For harvesting, the NexCo module integrates an axial rotor measuring 5.8 meters, combined with a 32,000-liter grain tank.

Technical Configuration

The platform features a hybrid-electric configuration:

• Two diesel engines rated at 545 hp each, operating as generators

• Compatibility with alternative energy sources, including fuel cells and full electric systems

Traction is provided by four electrically driven track units, which can rotate up to 90 degrees to adapt to different field operations and transport positions.

System Architecture and Operation

The machine integrates:

• An environmental monitoring system for field data collection

• A central operator cab with 270-degree rotation, enabling supervision across different working positions

The overall concept is based on reducing the number of machines required per farm by consolidating operations into a single platform.

Market Context

Nexat reflects a broader trend toward:

• System-based machinery concepts

• Integration of multiple field operations

• Increased automation and electrification

However, its large-scale platform architecture represents a departure from conventional tractor-implement systems.

Analytical Conclusion

Nexat introduces a platform-based approach to crop production, challenging traditional machinery configurations centered on individual machines.

While still at a prototype stage, the concept signals a potential shift toward integrated, high-capacity systems designed to optimize field efficiency and operational continuity.
