I'm in the process of trying to scoop up about 30 yds of stone from around my filled-in (Dirt) swimming pool. Looks like the previous owner had laid down some fine pea gravel first (about 4-5" thick) then laid regular sized stone over that about 6-8" thick. I've made a few passes with my box blade and it worked fairly well but as I go deeper i'd like to minimize the amount of soil i am also digging up. Would a lawn rake do a decent job of dragging the stones a distance of about 25' without making a big mess?
