Didn't have a $40,000 bean roller but did have a couple hundred invested in two Case land packers. Made a squadron hitch to pull them both and use them to roll bean ground. Pulverizes the clods and root balls and will push softball size rocks down. Leaves the ground textured so it don't blow or wash quite so easy. Cover 25 acres an hour at 30' width. Necessity is the mother of invention.
