What is ISOBUS?

ISOBUS is an international standard that ensures compatibility and connectivity between displays, tractors, and implements, regardless of brand. ISOBUS empowers producers, giving your operation greater flexibility when implementing technology so you can ensure your mixed fleet is as efficient as possible.


Different Classes to Fit Your Needs
ISOBUS automation capabilities can be broken down into three classes:

ISOBUS Class 1: Implement provides feedback via in-cab display.

Example: track individual bale data from Case IH RB5 series round balers​

Case IH ISOBUS Class 1 Offerings:​
Farmall® ​Series tractors​

ISOBUS Class 2: Basic controls from tractor or display to the implement.

Example: Setting up the implement and controlling the depth with AFS Soil Command.

Case IH Class 2 Offerings:
Magnum™ series tractors
Steiger® series tractors
Tiger-Mate® 255 field cultivator with AFS Soil Command™
Patriot® series sprayers
Trident™ combination applicator
Precision Disk™ air drill
Precision Air™ air cart
Precision Hoe™ air drill
Flex Hoe™ drill
Nutri-Placer® pull-type fertilizer applicator

ISOBUS Class 3: Incorporates global positioning inputs, two-way communications and two-way controls between tractor and implement, facilitated by an ISOBUS-compliant display. This allows for both implement automation and for the implement to control certain tractor functions such as ground speed.

Example: Let the baler control the tractor with Feedrate Control on select Case IH large square balers

Case IH Class 3 Offerings
Optum® series tractors
Puma® series tractors
Maxxum® series tractors
LB4XL and LB4 HD large square balers
RB5 series round balers


ISOBUS – Past, Present and Future

As farming technology expanded, lack of compatibility among platforms, equipment and implements became problematic. Every piece of equipment required its own proprietary display.

Agricultural equipment manufacturers around the world came together under the International Standards Organization (ISO) and agreed on ISOBUS as the universal protocol for electronic communication among implements, tractors and computers

In order to minimize the room for interpretation of ISOBUS standards, The Agricultural Industry Electronics Foundation (AEF) develops guidelines which add to the ISO standard and thus allow for precise definitions of ISOBUS functionalities. The AEF offers testing and certification of ISOBUS products.

Ultimately, the goal is plug-and-play capability for every combination through standardized ISOBUS components. That means one ISOBUS display, such as the Case IH AFS Pro 1200 display, in the tractor or sprayer controls any implement or application.


Bringing it All Together

ISOBUS universal protocol brings several advantages to agriculture:

  • Simplification. Your Advanced Farming Systems (AFS) Pro 700 display interacts with multiple implements and machines, regardless of manufacturer.
  • User-friendly. ISOBUS standardizes control settings, reduces downtime and minimizes installation and interface issues.
  • Easy connections. The standardized, nine-pin plug makes it easy to connect different components.
  • Automation. Implements can control the tractor for incre​ased efficiency and reduced operator fatigue.
  • Less cab clutter. A single display manages multiple implements and tasks, creating improved visibility for the operator.
  • Increased efficiency. Easy data exchange from the display, produces flawless precision farming documentation.



The ISOBUS System – Functionalities and Equipment
A modern ISOBUS system consists of tractor, terminal and implement.

ISOBUS improves performance through standard functionalities as defined by the AEF.

An ISOBUS functionality is like a separate module on the ISOBUS. One or more functionalities can be bundled together and then interconnect with other products that contain additional functionalities. Only functionalities supported by all components involved are available for a true plug-and-play experience.

Functionality examples include:

  • Universal (virtual) Terminal - The capability of operating an implement with any terminal and/or using one terminal for operating different implements
  • Auxiliary Control - The equipment allows for additional control elements, such as a joystick
  • Task Controller - Allows for GPS based control of implements


Equipment req​uirements — Functionality depends on tractor-implement combination

  • Implement and tractor must meet configuration requirements:
  • Implements must be fitted with ISOBUS electronics and software
  • Tractors require specific transmission types, depending on model and desired level of ISOBUS functionality
  • Choose the appropriate display for your desired ISOBUS functionality
  • Unlock codes — available from the Case IH Partstore — allow ISOBUS Class 3 automation
