Custom two-stage "scalping" auger bit for large-container plantings

I provide details on a customized auger attached to a skid steer, which I use in one automated action to dig holes and to create a scalp and water basin for large-container plants. For less than US$ 1000, I modified a John Deere auger bit and have since used it to dig more than 12 000 holes in a variety of sites, with only minor maintenance needed.
