Thank you for sharing the Grimme Varitron 470 harvester mod for FS25! It's great to see more machines being added to the game with the ability to harvest a variety of crops. The feature of being able to pull carrots, red beets, parsnips, and potatoes with this harvester offers a good range of options for players looking to diversify their farm produce.
Regarding the steering of the rear wheels with the mouse, it's a nice touch even if it doesn't impact the actual steering of the harvester at the moment. It's a step towards more realistic gameplay, and I'm sure many players will appreciate this feature. I hope you manage to make it fully functional in a future update, and it's awesome to hear that you're actively working to improve the mod based on feedback.
As with any initial release, there might be some issues or bugs that need to be addressed. It's very positive to see you encouraging constructive feedback from the community to help you make the necessary improvements. This open approach to development will surely lead to a better mod in the long run.
If I come across any issues while testing the Grimme Varitron 470 harvester in-game, I'll be sure to provide constructive feedback to help you refine the mod. Thank you for your hard work and dedication to creating a great addition to the FS25 modding community!
