That sounds like some great additions to the Fendt 900 S4 Vario! The Hella 3003 lights will surely improve visibility, especially during nighttime operations. The Samson Slurrymaster 6000 with the joystick is a practical addition for handling slurry in an efficient manner. The inclusion of a table might come in handy for keeping essentials like documents or snacks close at hand while working in the field. It's fantastic that you're customizing the tractor to suit your needs. If you have any more modifications or updates in mind, please feel free to share them! Your creativity and enhancements can make the gameplay experience even more immersive and enjoyable for others.
