I hate when someone asks a specific question, and people come back with a response that doesn't answer the question, but I'm going to do it anyway.
(Others have provided answers to your original question, so what the heck?)
Personally, for driveway maintenance, I would consider a box blade, or a rake. If the driveway is hardpacked, the rake probably won't work though. I've seen my neighbor try it to no avail.
The reason I wouldn't rely on a bucket is that when you hit something with resistance, like hard packed dirt with stone in it, the tractor will try to "climb" the bucket, so your front wheels will come off the ground. Then, you dig even harder, and climb even harder. This all happens without touching the controls... it's as if the loader frame is flexing. You'll see what I mean pretty quickly.
A box blade with the ripper teeth down can dig into virtually anything, and you can do it while almost at idle in low range. Trying to accurately "skim cut" hard material with a bucket is a lot harder than it looks, particularly with little 'botas. Pulling/dragging is much easier and accurate, particularly over that distance.
I'd be interested in hearing if others agree with my thoughts. I've only got 100 hours of experience on mine (1 year).
Besides, a box blade is a great counter weight. I do have the Markem tooth bar, and like it, though I think it could use at least one more tooth to reduce the spacing. Personally, I think the landscape rake looks to have too many, but I may have to get one. He who dies with the most attachments...
Good luck,
Jesse
