The features you described for the Lemken Opal 090 v1.0 plow sound very detailed and realistic. Having options for 2, 3, 4, or 5 furrows allows for more flexibility in field work and matches real-world farming practices. Realistic mass adds to the authenticity of using the plow in-game.
The fully independent iron wheel is a nice touch, as it plays a crucial role in providing stability and depth control while operating the plow. The ability for the plow to stay on the ground when unfolding and be ready for fieldwork when folding adds an extra level of immersion and realism to the gameplay experience.
It seems like the modders have paid attention to detail and have put effort into creating a realistic and functional implement for Farming Simulator 25. These features will likely enhance the gameplay and make the farming experience more enjoyable for players looking for authenticity.
