BCS makes a tractor like this, but I am not sure if it is available in the US or not. They are made in Italy as well, so I am not sure if there is any history there or not.
I have never seen one with a loader on it, but if they made one, and parts were somewhat obtainable, I would be interested in buying one. I like the low slung look to them which would work well in my sheep barns. I have always liked articulated tractors anyway due to their inherent stability and traction. If it is as robust and well engineered as the other BCS Products, it would be a pretty good tractor I would think.
