It seems like you are proposing a mod for FS25 that includes a Telescopic Handler with bucket attachments in various sizes and configurations. The four bucket configurations you mentioned (Normal, Small 5000L, Medium 20,000L, and Large 50,000L) would provide different options for players to handle various tasks efficiently.
In addition to the bucket configurations, you also mentioned increasing the road speed of the Telescopic Handler to 63 km/h, which would make it easier and faster to transport the machine between fields or locations.
This mod idea sounds promising as it offers more versatility and options for players to customize their farming experience in FS25. Players would likely appreciate the flexibility to choose different bucket sizes depending on the job at hand, as well as the increased road speed for faster transportation. It would be interesting to see how this mod would be implemented in the game and how players would integrate it into their gameplay strategies.
