CHCNAV NX612

Advanced Auto-Steering for Precision Agriculture

The CHCNAV NX612 is a high-precision automated steering system built for modern farming operations. Offering ±2.5 cm accuracy with SkyTrix GNSS technology—even in remote areas without RTK network coverage—it enhances productivity and precision across a wide range of agricultural tasks including seeding, spraying, tilling, and harvesting.

With its integrated design, powerful torque motor, intuitive 12.1” touchscreen interface, and broad vehicle compatibility, the NX612 makes advanced guidance easy to adopt. Its compact motor design saves cab space, while the ISOBUS-ready controller and wireless connectivity ensure seamless integration and updates.
