We are pleased to announce the release of the new Stonex Agriculture solution AG400 Auto-Steering System.
AG400 integrates GNSS positioning with automatic control technology to ensure an operational accuracy of ±2.5 cm, even in complex terrain conditions. It is compatible with a wide range of agricultural machinery, including tractors, transplanters, sprayers, harvesters and, thanks to ISOBUS protocol, with multifunctional farm implements.

AG400 Auto-Steering System offers modular solutions for precision farming, ranging from simple manual guidance (AG400 Lite version) to advanced implement control via ISOBUS protocol. Install the system without the need of hydraulic circuit HW modifications and be-ready to work in less than 30 minutes.

The intuitive Android Auto-Steering software makes the solution simpler to use, increasing the productivity and optimizing the working time. Guide automatically the tractor on straight, curved, pivot or mixed routes on various terrain, executing low-speed tasks, and performing high-speed operations. Use the free U-Turn functionalities to optimize the tractor route, calculating automatically the correct turning radius to perfectly align with the next lane
