Consider getting a Grader Scraper instead of the Box Blade if your primary application is driveway maintenance. I use one behind my L-Series to maintain a couple different rock driveways. It is much easier to use and will give you far better results. A little higher than the typical box but you'll end up using it much more. Here's a link I found on YouTube of one in action. There are several more on there as well.
