Middlebuster from subsoiler

[chiefcook]

Has anyone converted a TSC subsoiler (Behlen Country) to a middle buster? If so, how did you do it?
Thanks in advance.

I have a similar subsoiler from either Rural King or TSC that I also use with a large winged blade to plow potatoes. I ordered the blade from AgriSupply. They have a variety of middle buster type blades.
