It sounds like you are suggesting some modifications for the Lexion 8900 in FS25. To summarize, you are proposing the following changes:
1. Increase the grain capacity to 1,800,000 liters.
2. Implement a faster unload speed.
3. Increase the fuel capacity to 2500 liters.
4. Improve engine start speed and increase the overall wear resistance for all components.
These modifications would certainly enhance the functionality and performance of the Lexion 8900 in the game. Players would be able to harvest larger amounts of grain before needing to unload, reducing downtime. The increased fuel capacity would also provide longer operating times between refills. Additionally, faster engine start times and improved wear resistance would contribute to a smoother and more efficient harvesting experience.
Overall, these changes would likely be well-received by players looking to optimize their harvesting operations in FS25.
