Here's a few pics of my BB grader mod inspired by TBN member ideas and comments.
This piece bolts on the bottom of the BB.
It is essentially two angled cutting edges connected to two side skids (skis).
The rear hooks over the rear BB blade and two bolts on the front hold it in place.

The leading tip of the side skid is turned up like a ski.
The skid is extended back beyond the rear blade about a foot so that the TNT can be used to tip the BB back on the skid and lift it, to dump material.
The front blade is serrated and all cutting edges were hardened with welding rod. The cutting edge of the actual BB is 3/4 higher than the grader blades to allow material to be metered out the back while the front blades cut.
It does a great job for any sort of cutting or leveling work such as landscaping or road maintenance.
It also adds about a 100 lbs of
ballast to the back which is nice when doing FEL work. I don't remember the last time I took it off the BB. As for my gauge wheel, it hasn't been used since I made this thing.
