I am purchasing a utility tractor and some attachments and want to do some lawn installations on new construction. I assume I will be comeing in with everything finish graded and want to prep the soil. Much of the time I will be involved with heavy compacted clay. My first thought was to get box scraper and tiller, and use the tiller to loosen the soil, and then use the box to level things out. I don't want to ruin the grade either. I don't know how valuable the box scraper would be, perhaps a landscape rake would be better. Do you fellas use either of these tools much for installs? I then thought running over it with the tiller, and then following it with a pulverizor may be better yet. Would this be better at keeping the finish grade, or would I still need a box scraper or rake, or even an angleing rear blade? Would suggestions do you have for a green horn? Thanks a bunch!
