There are several guys on here that have them, and they will ring in. Those that have them, love them. They blow or mow so many leaves into a pile where they aren't that movable anymore, then just hit them with that thing to take them the rest of the way to the road or wherever. Some, in smaller yards, just use them to push the heavy right out row by row. There have been a few that have even built their own. We'll be hearing quite a bit more about these in the near future with leaf season coming on.
