With FS17 all tractors have a free swinging front axle just like in real life to keep all 4 tires on the ground in uneven terrain. Sadly, as soon as you attach a frontloader the axle gets locked in place.
So yeah, in short, this mod removes the lock from the axles so they can swing freely with a loader attached just like they do without loader. If you are out for some kind of realism in this game, this is the mod for you. (Assuming you do not play MoreRealistic Mod as “MoreRealistic” vehicles also come with this feature already)
