Hello, I was reading allot about box blades on here. It seems there well liked. I have never been around one or used one. I work for a municipality and am required to maintain several miles of crusted rock alleys and several blocks of gravel streets. We have a old Adams 8' pull type grader on steel wheels I have been using. Do box blades work good for fine grading? Will they penetrate hard crushed rock and gravel uniformly? How well do the rippers work? Are the units that fleet and farm stores sell good? advantage over a regular blade? looks like 60" and 72" box units are in the 3-400$ range at these places. I'm not looking to replace what the pull type does I need the lateral tilt to maintain crowns. But would like something easier to use when I get a just few pot holes in some areas rather than drag the noisy, clumsy pull type around every few days. I would be using it on a B7610 kubota. Thanks
