For a 4-wheel tractor, draw a rectangle that indicates the tire contact point of the tires. As long as the center of gravity stays within that rectangle, the tractor will not tip over.
Draw a triangle for a narrow front tractor that includes the point where the tires contact the ground. If the center of gravity moves outside that triangle, the tractor will tip over.
In this situation, the rectangle has more area than the triangle, thus making it less prone to tip over. Moving the wheels further out or adding duals makes the rectangle larger.
Just things to ponder. Needless to say, the vertical point of gravity changes with the height of the tractor and can make certain tractors more prone to tipping over. Guess that's why I like lower utility tractors.
The oscillation of the wide front is usually limited, but until the tractor frame stop contacts the wide front axle, the tractor is a actually a 3-point suspension, when the oscillation limits are reached, it becomes a 4-point suspension.
