I am Sándor Szaszkó, front man of AgOpen shop, managing director of Szikkim Ltd., and a qualified electrical engineer. I have been working in the field of IT systems development, product and team design for two decades.
I grew up in a family of farmworkers and since 2020 I am back at actively farming. My all-purpose tractor was equipped with a motorized AgOpenGPS in spring 2022 and my tillage machine with a hydraulic thumb in autumn 2023. Building a system that worked took months at first, I spent countless hours browsing forums, buying parts that were ultimately useless, but the joy of creation was with me throughout.
Our products are intended for those less motivated when it comes to digital challenges or have less background knowledge. Or just simply have less time.
Balázs Gunics is the technical expert of AgOpenGPS Shop.
As a farmer, he has also undertaken a lot of work in developing the domestic network. He is an active member of the AgOpen community. He also supports the members of the community and the Hungarian farmers who are currently joining on the social media channel, providing professional assistance in installing and operating the hardware necessary for the free AgOpen application available to everyone.
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.
