Deutz-Fahr developed the Tractor Assisted Guidance System (TAGS). This takes advanced driver assistance technologies into agriculture, tailored to unique working conditions. It is a step forward in both on-road and field automation and safety. TAGS was awarded a Silver Medal at Agritechnica 2025.
Unlike conventional automotive ADAS (Advanced Driver Assistance Systems), which are tailored to smooth roads, uniform traffic, and fixed infrastructure, TAGS is specifically developed for agricultural use, supporting both road transport and field operation. Whether navigating narrow rural paths, varying terrain, or mixed-use field environments, it goes beyond standard sensors and software.
TAGS is built around the concept of ‘tractor as a sensor’. This means the tractor becomes a smart, connected hub that continuously gathers and shares data from the field. By integrating sensors, connectivity, and intelligence directly into the machine, Deutz-Fahr transforms the tractor into a central node of the digital farming ecosystem, enabling more precise, efficient, and safer operations.
TAGS is based on agricultural-rated, digital high-resolution cameras with High Dynamic Range (HDR) capability, fully integrated into the tractor’s design. These cameras deliver fast, high-quality images and are water-repellent, shock-resistant, and built to withstand the demanding conditions of fieldwork. The system is scalable and supports up to three mono cameras.
For advanced functionality, the stereo camera units offer real-time 3D scene mapping. Deutz-Fahr’s system measures actual depth, shape, and object movement, enabling the tractor to truly understand its surroundings. This is essential for safely and efficiently navigating challenging terrain, including uneven ground, unmarked paths, and crop-covered fields.
To offer customised performance across different farming profiles, the system consists in two levels: a Standard and an Advanced version.
Standard level
Lane Assist – Keeps the tractor safely in lane, with visual and acoustic alerts
Human Detection – Warns about people in the tractor’s danger zones
Crossroad Assist – Expands the operator’s view to a 190° stitched front panorama
Overtake Indicator – Alerts when vehicles approach from behind
Advanced level
Off-Road Lane Assist – Identifies navigable terrain, even without lane markings
3D Obstacle Detection – Recognizes static and dynamic objects
Adaptive Cruise Control (ACC) – Maintains safe distance on road and field
Traffic Sign Recognition – AI-based classification with automatic alerts
Powered by a high-performance AI-ECU – ready for future autonomous functions
Specialist support
Combining stereo vision, real-time AI, and a highly scalable system architecture, TAGS – Tractor Assisted Guidance System is the result of DEUTZ-FAHR Research and Development, with the support of Stereolabs (France), a specialist in real-time spatial AI, and engineering university Politecnico di Milano in Italy.
