To ensure you select the correct adapter, the most reliable method is to remove the steering wheel and measure the diameter of the splined shaft, as shown in the image.
In most cases, the spline count is 36; therefore, the diameter is the determining factor. Based on our experience, dimensions are consistent across certain brands.

Internet connection: This is used to receive the correction signal required to achieve 2.5 cm (RTK) accuracy. For machines used by family members, it is practical to provide internet access via a smartphone hotspot (eliminating extra data costs and administration).
An Ethernet adapter is required for AgOpenGPS control. This can be handled with an external USB-to-Ethernet adapter. While this setup is usually very stable, it does introduce more potential points of failure.
The Wheel Angle Sensor (WAS) provides the real-time steering feedback required for centimeter-level accuracy. While the system can operate without it at high speeds, a WAS is essential for precision tasks like planting or spraying and for reliable performance at speeds below 3 km/h.
Note: If you prefer a Kyocera sensor, leave this unchecked and add it to your cart separately.
