I am about to take delivery of an L4701 and I've decided to include a grading scraper with the purchase. I am a big fan of the attachment for driveways, parking lots, and leveling befor planting grass. I am wondering if anyone has used one to prep a large field for planting? I have about 4 acres that was planted with apple trees. Before I bought it they pulled the trees with an excavator so there are hundreds of 6-8" divots in the field. I plan on spraying a broadleaf herbicide and mowing for a few years to kill all the apple suckers and other weeds and will eventually plant trellised grape vines. I hadn't planned on rototilling or leveling the dirt prior to planting but now I am honking that it would be nice to have a smooth surface to start with and cut down pothole bouncing. Will the grading scraper work through grass in fairly sandy soil or will I have to spray roundup on everything and kill it first? Thoughts?
