AgOpenGPS, Sándor Szaszkó
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.

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.
