Introduction: Why our ISOBUS solution deserves your attention

ISOBUS (ISO 11783) is a global standard for communication between the implements and the tractors, regardless of manufacturers: it is the "universal language" developed to offer greater compatibility and simplified controls.

At FieldBee, we have adopted the ISOBUS standard through our ISOBUS Kit, providing farmers with access to advanced features such as:

  • Universal Terminal (UT): Control any certified ISOBUS-equipped implement directly from the FieldBee tablet.

  • Task Controller (TC): Manage both Section Control (TC-SC) and Variable Rate Applications (TC-GEO) for greater precision.

  • Seamless integration: Quick installation, full compatibility with the automatic guidance system, and operation through a single display.

This guide will explain our ISOBUS Kit, how to use it, and other preparation steps for ISOBUS FieldBee.

1. ISOBUS: fundamental concepts that every farmer should know

What is ISOBUS?

ISOBUS is a CAN-based communication standard designed to ensure compatibility between implements from different brands and a wide range of control hardware.

The result? Farmers can operate implements from multiple manufacturers using a single display — avoiding the need for multiple monitors and eliminating confusing or incomplete interfaces.

Key ISOBUS Components

To better understand how ISOBUS works in practice, here are its main components and their functions:

  • Virtual Terminal / Universal Terminal (VT/UT): The single in-cab interface used to control ISOBUS implements.

  • Task Controller – Base (TC-BAS): Records job data (e.g., worked area), useful for post-season reporting.

  • Task Controller – Section Control (TC-SC): Automatically switches implement sections (e.g., sprayer nozzles) on and off to prevent overlaps.

  • Task Controller – Geo (TC-GEO): Executes variable-rate applications based on prescription maps.

  • Tractor ECU (TECU): Acts as a bridge, sharing tractor data (e.g., speed) with connected implements.

  • Auxiliary Controls (AUX-N): Physical buttons for quick actions (e.g., changing a nozzle).

Note: Not all combinations are always possible — please consult your dealer for proper verification.

2. ISOBUS in action

ISOBUS brings concrete advantages across different farming operations — from sowing to spraying to harvesting. Here’s how it works in practice:

Sowing and Fertilisation

  • Section Control prevents double work or missed areas in the field.

  • TC-GEO applies seeds or fertilisers at variable rates based on prescription maps, improving efficiency and reducing input waste.

Spraying

  • Control sections down to the nozzle and boom level to avoid drift and waste.

  • TC-GEO enables variable-rate spraying, ideal for treating areas with higher disease or weed pressure.

Collection Operations

  • Monitor performance metrics and combine data directly on your FieldBee tablet (UT)

  • Use TC-BAS to record harvested areas and integrate them into your farm software.

  • Operate chaff spreaders or headers with Section Control (TC-SC), eliminating overlaps and protecting crop quality.

3. FieldBee ISOBUS Kit: Your tool for smarter farming

The FieldBee ISOBUS Kit brings professional ISOBUS functionality to your tractor — without the need for additional stand-alone terminals.

What’s included:

  • Physical wiring and connectors to add ISOBUS ports to your tractor.

  • Licenses for UT and TC-BAS, with an optional upgrade to TC-GEO (variable-rate application).

  • Full integration into the FieldBee Tablet, combining automatic steering and implement control on the same screen.

  • Cost-effective and quick to install (typically under 20 minutes), with no external terminal required unless specifically requested by the customer.

4. How to set up and use ISOBUS with FieldBee: a step-by-step workflow

The kit is simple to install and operate, guiding you step by step from setup to data analysis:

1. Install the kit

  • Fit the supplied ISOBUS wiring harness — no extra cables or shields required.

2. Connect the implement

  • Plug in your ISOBUS-compatible implement.

  • The FieldBee Tablet will automatically detect it via UT.

  • If the implement supports Section Control or Variable Rate distribution, these functions will appear through the manufacturer’s original interface.

3. Plan and upload prescription maps (optional)

  • For variable-rate operations, import field prescription maps into the app (formats supported: GeoTIFF or ISOXML).

4. Operate during work

  • Monitor and manage tools through the UT interface.

  • Section Control (TC-SC) automatically switches sections based on field position.

  • For variable-rate tasks, TC-GEO adjusts output in real time according to the map.

5. Record and analyse

  • Use TC-BAS to export recorded data — perfect for reviewing performance, generating reports, and refining plans for the next season.

5. Testing tips: Making ISOBUS work  

  • Check compatibility. Consult the implement manufacturer’s specs or the AEF ISOBUS Database.

  • Start with one task. Begin with spraying. Get comfortable before moving to variable-rate work.

  • Practice Section Control. Test in a clear field to avoid overlaps and learn the controls.

  • Record your work. Use TC-BAS to keep logs and meet compliance requirements.

6. Benefits of ISOBUS with FieldBee

  • Efficiency: One device, one interface — no duplicate monitors or controls.

  • Precision: Targeted applications with reduced overlaps and variable-rate dosing.

  • Data-driven decisions: Every job is recorded for planning, reporting, or validation.

  • Future-proof: As tractors and implements evolve, ISOBUS guarantees ongoing compatibility.

7. In short, ISOBUS with FieldBee means:

  • Simplification: One terminal to control all implements, freeing up cab space.

  • Smarter use of inputs: Section Control and variable-rate dosing reduce waste and optimise yield.

  • Harvest efficiency: Yield data and section logic make combine passes more efficient and improve quality.

  • Data and registration: TC-BAS records your work automatically — no more manual spreadsheets.

  • Wider compatibility: Works with implements from different brands, today and in the future.

Conclusions

ISOBUS isn’t just a buzzword — it’s a practical, modern standard that brings precision, clarity, and efficiency to everyday farming. With the FieldBee ISOBUS Kit, you can put this power directly on your tablet, gaining smarter control for harvesting, spraying, planting, and long-term farm planning.
