I think the trick with the smaller tractors and these machines are just go over it again and again to get the results
Yes, I tend to go up, then back down OVER what I just did, usually two trips up and back, so each piece of ground is hit four times, I'm mostly doing weed control now that I have my driveway done ... It's also better a day or three after an inch of rain ... When it's dry like this, it's tough going ...
My driveway looked like this after a weak dose of glyphosate, which I'd rather not use ... It was getting out of hand on my driveway, so I sprayed it ...
It was recommended on another forum to triple my strength, and wait another week ... So I sprayed it again!
The next time home in about 10 days it was a bit "damp" out, but I ran the land plane anyways, as that's when I had time!
You can see how wet it was here ...
Since the blades only stick down 1/2" now, they don't upset the weeds with longer roots, unless one of the little teeth hits them ... So I want to do it more often now ...
but I think the land plane with scarifies is the way to go.
I don't have them, and on a established driveway, I've read its best to leave the base layer(s) alone, and not disturb the bigger rock, and just smooth the top finish layer ... But trying to "reclaim" a driveway that is very neglected, that you may end up top dressing with smaller gravel, it seems like a good addition ... Or not dig them in very deep, like 2" - 3" ... ?
I do use my old 72" rear blade once a year to scrape the edges back, then follow up with the land plane ...
My driveway doesn't get washouts or washboards either, so it's not in very rough conditions, I'm just trying to keep it looking nice ...
