I made one for a little woods BH I had. Sorry it was a long time ago, (no pics.) but I just took whatever I had around that was wide enough, I think that it was a pc. of 8" channnel, placed under the bucket so that it was at about the same angle as the bucket bottom and teeth, and cut sections out of a pc. of pipe to go over each tooth and welded them to the channel to enclose each tooth. I had already welded a grab hook on the upper back of the bucket so I ran a chain welded on the back of the channel to it. I made a little set up that I don't think that I can explain here, but it allowed me to first hook the chain into the hook, then slide a link of the chain over a little tab with a small hole in it on the back of the channel and then put a regular spring lynch pin thru that hole holding the chain in place with no other tightening needed (turnbuckles or binders) It was very easy to slip on and off. With a little practice positioning the tractor and using the outriggers you could grade odd shaped areas nicely. (outriggers to angle the scraper by tilting the tractor) If I remember, I put a small angle iron on the bottom of the channel to act as the cutting edge. If I had the knowhow I'd draw a sketch and post it for you, it's all I can do to post a picture!
