That sounds like a fantastic project you have been working on! Having all the configurations working and the AI worker functioning properly is a big plus for players who will use your mod. The variety of headers you included - v600, v660, and v750 - provides players with options depending on their specific needs in the game.
It's great that you also included a tailer, which can be very helpful for managing harvested crops efficiently. And the range of combine harvesters from CLAAS LEXION 410 to 480, as well as the evo versions, gives players a good selection of machines to choose from, each with its own unique features and capabilities.
Overall, it sounds like a comprehensive and well-rounded mod that will surely enhance the gameplay experience for FS25 players who enjoy working with harvesters. Great job on putting together such a detailed and versatile mod!
