What exactly is AgOpen Shop’s steering system and who is it recommended for?

Our system is based on the globally popular, open-source AgOpenGPS software. Our mission is to provide farmers with an affordable, professional precision farming tool. By scouring internet forums, anyone can put the system together, but this often involves long part hunts, soldering electronics, and crimping cables. We provide a complete hardware package pre-assembled, programmed, and tested in our workshop (a Plug & Play style kit) that you “”only”” need to install into the machine.

Adapters for different tractors

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.

Models for which the data in the table below are highly reliable:

  • John Deere and newer machines from the CNH Group: A+

  • Claas and Massey Ferguson: N

When do I need a 4G router?

Add an external 4G router to your kit if: 

  • Tablet has no LTE modem: Your tablet lacks a built-in SIM slot, and you don’t want to rely on your phone’s mobile hotspot.
  • Weak signal coverage: The external antennas provide a stable internet connection in remote fields where standard mobile phones often lose reception.
  • Section controller setup: You are using an extra control board for automatic section control or sprayer management. This setup utilizes the router’s Ethernet hub function, where a third Ethernet cable is connected directly to the SC to ensure seamless communication between the devices.
