Hello; That attachment that looks like the comb on a roosters head is the most efficient way to get rid of the entire stump in my book. I like several of the others, but some of the other attachments consume too much time. I love these giant machines, I sometimes imagine them as robotic dinosaurs eating away at the wood stumps. They're so cool to watch, and in a way they feel lifelike by the way the move, almost like real creatures. They look so fun to operate!
