All good advise. A lot depends on the make up of your lane, it's steepness, and your local weather. A guy in Florida with a level pea stone drive who never plows snow would probably be satisfied with a rake while a guy up north with deep winter frost, which makes for muddy springs, and a hard packed gravel hilly drive needs more than a rake because he has to cut and move hard packed gravel to grade his road which a rake won't do by itself. I have such a road about a mile long, The lower half is a good road with a proper base and good gravel the upper half was a dirt logging road that I upgraded over time little by little by mixing in stone with the dirt. I used a rear blade for 10 years to maintain it. Then I got a land plane. Now I use both but mostly the land plane. It is a great maintenance tool.
There are lots of considerations. Check out what people around you with similar drives use and compare it to what has been said here, there is a lot of experience to read about here.
If you do much tractor work you will probably end up with several dirt tools. They all have there place and main specialty or purpose but they also can be used effecively in a wide range of work outside of there specialty. I would say the rear blade is the most general purpose and universal road tool. Buit it takes a lot of time and practice to develope the skill to use it at it's maximim potentential. The box blade is less universal but easier to master and better for moveing dirt than the blade. The land plane is surface maintenance only, leveling pot holes and wash board, rejuvinating and mixing gravel, and maitaining crowns. It is easiest and fastest to use by far so you can keep your road in better shape. By keeping the road in better shape you get less damage from storms or traffic.
This is just my opinion of course. Many have different ideas.
