I'm just in research mode at this point.
I've looked at articulated 4x4s (as twoton surmised the other day) but don't see a practical use for one that a regular Cub can't do almost as well. (unless I'm missing something). They are neat, and a bunch have been done. But I'm not sure I'd actually use it for anything.
I've always been fascinated by motor graders. I have a good bit of gravel drive to maintain and rear blades on my other tractors (the Ford and the Kubota) work OK but still suffer from the fact that they are outside the wheelbase, so don't have the leveling capability that a belly mounted blade has. Of course, the longer the wheelbase, the better the belly blade works at leveling.
I'm just noodling on what to try next...
