FJD AT2 Auto Steering System

±2.5 cm Precision Steering with GNSS and RTK

The FJDynamics AT2 is an auto-steering system that uses GNSS and RTK to guide your tractor along straight, curved and pivot paths with ±2.5 cm pass-to-pass accuracy. It can be retrofitted to tractors, combines and many other farm machines.

The AT2 is the most widely used model in the FJDynamics steering family and works across Türkiye in everything from seeding to harvest. It consists of an electric steering motor, a GNSS antenna and a 10.1-inch touchscreen terminal; it replaces the existing steering wheel and needs no changes to the hydraulic system. Once the operator records an A-B line, the system drives every pass at the same spacing, cutting overlaps and gaps and saving seed, fertiliser and chemicals. Lines are held even at night and in dusty conditions, and the operator can focus on the implement instead of the wheel. The built-in IMU compensates for line drift on slopes. Field profiles, boundaries and lines can be saved and transferred to other machines by USB, and ISOBUS support lets compatible implements be managed from the same terminal. The AT2 Max offers a larger screen, and the AT2 Lite a simpler starting point.

The system components and key technical values are summarised in the image below; the full list is in the Specifications tab.

AT2 Functions

±2.5 cm Line Accuracy

This accuracy comes from combining the GNSS signal with an RTK correction signal, which can come from an RTK base station or an NTRIP service (CORS network).

Field Management

Create a profile for each field with its boundaries, guidance lines and tasks, and carry on with the same lines next season.

Advanced Guidance Lines

Straight, curve, A+ and pivot modes cover different field shapes and jobs.

Terrain Compensation

The IMU sensor compensates for tractor roll on slopes, so lines on hillsides are as accurate as on flat ground.

GIS Data Transfer

Field data can be moved between machines on a USB stick in standard GIS formats, or imported from a farm management system (FMS).

Implement Control with ISOBUS

ISOBUS support lets compatible implements be controlled from a single terminal, reducing the need for extra screens in the cab.

Two Manual Override Modes

For safety, the operator can disengage steering and take over instantly in two different ways.

Automatic U-Turn at Row Ends

FJD U-turn plans turning paths based on the field boundary and completes the turn at the end of each row without operator input.

U and Fishtail Turn Patterns

Choose an automatic U or fishtail turn at the row end.

Note: U-turn is a separately licensed, paid feature.

Why Daze Tarım?

Daze Tarım is the official distributor of FJDynamics in Türkiye. We operate our own CORS-RTK network in the Marmara and Aegean regions, and customers who buy a steering system use it free of charge for the first year. Where the network does not reach, the FJD V1 portable base station gives you the same accuracy. We carry out installation, calibration and operator training on your own tractor, and provide spare parts and technical service.
