Well, it took a while, but I finally had a chance to use my box blade to fix my driveway. I was unsure how my little 28hp tractor would work with it, but I was amazed at how well it handled it. If anyone is in my situation and wondering if 28hp is enough for a 6ft blade, it is. I had all 6 scarifiers down, and the blade tilted quite aggressively to do the initial tearing up, and had no issues. It did bog down some in high range, which was no surprise, but worked great in low range.
I did 20 passes with the scarifiers to rip everything up, then about 10 passes with the blade to distribute everything more evenly. Things were a little wet, so I beat it all down by driving over it, and waited until the next day. Then I went over it another 10-15 times to smooth everything out, and I'm pretty happy with the results. Definitely better than it was or has been for years.
Below are pictures of before and after.
Thank you to everyone for your help and advice. I hope this conclusion may be useful to someone else in the same situation.
