As Diesel Don asked,I'll try for a short explanation, as I see it. A simple observation...gravity (and turning forces) pulls the tractor as if all its weight is concentrated at the center of gravity. That is by definition. The forces tending to upset the tractor must be exerted from the center of gravity through its' footprint of stability, or it will upset. A tricycle tractor's footprint of stability can be easily understood as the triangle drawn around the tire's contact with the ground. I think everyone can agree with that. The footprint of stability for a wide front tractor is a little more difficult to explain, since it is NOT on the surface. It is on an imaginary plane upon which the rear tire contact point with the surface and the front axle pivot point lie. Now, if a line were extended from the center of gravity through the boundary of this footprint to the surface, the projected footprint on the surface would be larger. This larger footprint allows the WFE tractor to work on a somewhat steeper angle before upsetting...and the primary stability has nothing to do with the axle stops. The axle stops do add a small measure of secondary safety. On the other hand, because of its' greater height of the center of gravity above the pivot point, the NFE requires less angle to reach the critical point. This effect is more pronounced when the tractor is in motion and turning, as common experience with loaders shows. Of course, the width of the rear axle is a bigger factor, but it is a mistake to think a NFE tractor is as stable as a WFE. It just simply isn't so. George Willer

Box Plow Blues - by Tom Schwarz. One of the first implements most tractor owners obtain is the box plow. For very little money, this piece of equipment promises to plow and flatten any hill or vale on your ranch road or farm. At least that's what I thought! As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U
