I looked in the Northern catalog also and didn't see anything. I would be using it on my Allis Chalmers D15 so I was thinking something with a few steel fingers to rip down through the soil. Maybe something would need to be fabbed up that could be bolted to the bucket.Northern used to have a single tooth for small tractors that would bolt on the bucket, like loader arms. I don't see it anymore online. Looked like a handy idea. It would focus the energy onto one small area which would give even small tractors more utility.
