Key Points

Reliable performance is provided by the CHCNAV NX612 Automated Steering System in a variety of agricultural environments. It is appropriate for precision farming anywhere since it easily links to GNSS RTK networks and CHCNAV SkyTrix satellite correction services, offering ±2.5 cm accuracy even in isolated locations without network coverage. The system’s small drive wheel motor increases operator comfort while conserving cab space. Operation is made easy and efficient by its industrial-grade 12-inch HD display, which features large icons, 3D views, and an intuitive interface.
