I am interested in getting a blade for leveling my driveway when I get some new gravel and to remove snow. I live in Northern Virginia area and we get snow a couple of times a year such that we need to use blades to remove it. Some neighbors have buckets and another neighbor or two have rear blades. I am inclined to get a manual rear blade although I do have the connections for a bucket if I wanted. But I think a rear manual blade that I can switch around for front or rear push or pull is adequate for me. Is there a width of a blade type that I need to be looking at for my need? e.g., 72 inch width? If I get a small blade I understand that I may have to get a blade extension if it is too small. But I would rather get the right size blade up front.
