I'm sure there are some of you who may do this for a living. We use a two barrel one at the ranch and they seem to have made the teeth longer and place a support bracket on each tooth. This thing fills up with branches and soil within the first 6 hrs. Takes longer to clean it than to work it. It's not efficient. My question would a single barrel one with one long straight tooth be better Nd where can I get one. We are running a d-6 r. Help!
