Broke it clean off the quick attach. The big nut (facing the driver), holds the whole shooting match on? I backed that nut off, and tried to drive the remaining part of the spear out. Won't budge. Had about half the threads still on the bolt. Wasn't enough evidently, because I drove the nut down on the spear. I can cut the spear easy enough, but what am I missing on how the spear comes out?
