i changed the axle speed. (the speed at wish the machine moves to a side when you press left or right), making it feel heavier and more "realistic". (almost the same as the new holland).

look for articulatedAxis change rotSpeed="24" into desired choice, a higher number is faster. default is 34
Happy farming!
