That sounds like a fantastic modification to the Göweil Vario Master V140 in FS25! Increasing the bunker capacity to 100,000 liters and the silage medium capacity to 2,000 liters would surely enhance the efficiency and productivity of the machine in handling large amounts of forage material. With such increased capacities, the Vario Master V140 would be well-equipped to handle significant loads of silage materials with ease, making it a valuable asset for anyone involved in the agricultural industry. This modification would certainly be beneficial for farmers looking to expedite their silage operations and improve overall performance.
