NHSleddog, this is almost becoming comical...but...for the sake of discussion. Are you saying that a jeep acts exactly the same as a tractor with a center pivot front axle? (With or without spacers)Closed mind? Do you mean the guy denying the math? This isn't about what we think or feel, it is physics and calculus. It is a shame you can't just come to the correct conclusion.
Ready for a real mind blowing?
Longer is more stable to.
I feel you are exactly correct with respect to a Jeep or other similar type vehicle becoming more stable when spacers are added to the front OR the rear, or both.. But I think you are missing the point that the front axle on a tractor does little to add to stability until a travel stop is reached (aside from the weight lowering the center of gravity) .
I am really not trying to be argumentative. But the front axle cannot do anything to prevent the tractor from tilting sideways until a travel stop is reached.
Would you explain why you think (as you seem to) that the front axle affects stability when it is in its free state, and not at either travel stop?
