System 350

The complete autosteer solution

Topcon’s System 350 smoothly merges high-accuracy autosteering/positioning with variable rate/autosection control, detailed mapping/data logging, and versatile information management with an easy-to-use interface and highly-capable equipment.

Featuring simple and flexible software, the X35 console provides a versatile work platform with features to improve farm management, increase efficiency, and enhance machine capabilities. The system’s AGI-3 receiver and steering controller features full terrain compensation plus superior line aquisition and holding capabilities. AGI-3 steering control options include AES-25 electric steering, hydraulic, or direct-interface with steer-ready vehicles. Spray control is provided via the system’s ASC-10 Auto Section Controller.
