It depends of the intended use too. Dragging, pushing, in forward or in reverse. A loader mainly pushes, like the tractor mainly pulls, but an excavator is mostly reversible and a mini in treework has to do both ways according to the task.
Maybe take notes of the mini's activities during all the day(s) to try to find a pattern, as when you need the most of effective traction power, which way , how often, do you use all you can get of it or have you some margin...
