There are single tooth buckets made for ripping roots, They aren't very common, but there are a few mfg that make them. I never bought one simply for the price they get especially when that price almost equals a new 24" bucket.. It would have to be a quick attach for my set up, and this adds a bit more, so for me, the amount of use moving roots and the costs, I would neve recover those costs, this is to include the little time savings a single ripper tooth can offer,
