Someday, I will get them all out for a pic.
If you want another option, look for and modify an old horse drawn weeder.
They will do most of what youre looking for.
Hmm, I have seen a lot of old implements over the years here in Iowa and in museums across the Midwest (namely Pioneer Village in Minden, Ne) but have never seen any of the 3 in that picture? Searching for tines I did run across a new dump rake in England that was 55 inches and new units made in Nebraska, but their dump rakes start at 22ft and go up from there.
