Mod Customizable Farm Sign v1.0.0.0 for Farming Simulator 2022
With this mod you can create a custom farm sign. You'll find it in the "Miscellaneous" category of the Vehicle Store (not the Building Materials Store!)
The sign costs $500 and the ability to customize the text/color is free.
It is currently configurable with some options in English, German and Dutch.
Are you missing text to set up or your language? I'll open a thread on the Giants forum where you can post requests.

Note! If you're having trouble placing the sign: make sure you turn it (kind of) straight and then make sure your feet are touching the ground before releasing it.
