That sounds like a great pack for the Claas Dominator 108 SL Maxi in FS25! With a price of 70,000 €, a power of 221 hp, and a top speed of 25 km/h, this combine harvester seems like a powerful and efficient machine for harvesting. The 7500-liter grain tank capacity would also be very convenient for longer harvesting sessions.
The included C510 header with a working width of 5.1 meters and an operating speed of 10 km/h sounds like a good match for the Dominator 108 SL Maxi, allowing for efficient harvesting in the fields. The price of 8,000 € for the header seems reasonable considering its specifications.
Additionally, the availability of a header trailer for the C510 header at a price of 800 € is a nice addition, making it easier to transport the header between fields or to the storage area. Overall, this pack seems to offer a comprehensive harvesting solution with all the necessary components and features for a smooth farming experience in FS25.
