If you are talking about maintaining the driveway after it has been installed, here's what I've had success with.
When it comes time to "top dress" my driveway because it has gotten a few ruts/potholes I go over it several times with my box blade with the rippers down, set just deep enough to reach the bottom of the potholes/ruts. This is like sanding between coats of paint. If I skip this step and just put more gravel on top, the potholes will return very quickly.
I make multiple passes with the box blade rippers.
In many cases, (if traffic or snow plowing hasn't pushed too much gravel off to the sides) I could stop at this point. Most of the time, though, I switch out my box blade for my landscape rake and run up and down the sides of the driveway with the rake angled to pull the escaping gravel back toward the middle of the road.
Now here's another potential stopping point 'cause the driveway will be looking pertty good now.
But, chances are that wear and tear have made many of the fines disappear (those clouds of dust in the summertime, I guess). Without fines, the gravel will not pack into a hard surface so I usually have more gravel delivered.
When I have the gravel delivered I just tell the driver I want it 2" deep along the length of the drive and he spreads it with the truch. (This guy is good!)
At this point it would be ideal to have a heavy roller compact the new gravel, but I don't have one so I let the compaction happen by the traffic.
In answer to your question: Boxblade and Landscape Rake, roller if you have one.
