It seems like you are describing a weight mod for FS25. A weight of 1000kg can be a good size for towing trailers, as it provides enough counterbalance for the tractors to operate efficiently. Having mouse control for moving the weight around can be very convenient for players, allowing for easy adjustments in the positioning of the weight.
A fixed mounting system ensures that the weight stays securely attached to the tractor, preventing any unexpected detachment during operations. Fixed textures help maintain the visual quality of the weight, contributing to a more realistic gameplay experience.
Fixing all log errors is crucial to ensure the mod runs smoothly without causing any issues or conflicts within the game. Overall, it sounds like a well-rounded weight mod that offers both functionality and convenience to players in FS25.
