I have a slightly larger tractor, but I've found that I can make a much more controlled mess with my box blade than I can with my loader. My land is old New England cow pasture pretty much so I've used it to find rocks near the surface, and remove them, to make small swales, and improve drainage from sheds, etc. to help fix up the mess the logging skidders did years ago in my woods when they logged there, and generally to just have a good time playing in the dirt. I have also found that with the blade adjusted right (riding on the rear blade) I can spread loam over rough areas of my yard, and just fill in the low spots without damaging the grass much at all.
BTW: the rough area on the right in the last picture was just a tiny part of the area that some wild boar dug up when they passed through. That clay was still pretty slick when I worked it too, and does look better now.
