I like the idea of the receiver and I think you will find it very handy.
For those who plan on doing something similar, let me share my experience.
I just welded on a hitch when I needed it, but when I got to doing a lot of blade work, the hitch causes problems with the rolling action of the sod, trash, whatever, when backing up, so I cut mine back off & bolted one on that could be removed when needed.
