You hook up a pond scoop to the two hydraulic lifts and to the third point. The one I have can be hooked up forwards (to scrape) or backwards (useful to remove dirt from an existing pile). If you get one, reread my notes in the post above about ensuring there isn't too much slack on the lower two hookup points. I think that's what bent my scoop.
