I made something like this
https://www.youtube.com/watch?v=h1nHHpBdFcA and mounted on the quick attach on my tractor. It worked pretty well for scraping up muck around the edges. I actually used an old antenna tower for the arm and used landscape rake tines for the head. It is pretty heavy. Would have been nice to use aluminum.
That is something like I had in in mind. Never got around to it and have not had the problem in my main pond since. One problem also is I have quite a bit of structure and rocks in the pond I wanted to use it in and it would definitely be hard on those things.
