Replying to an earlier question, no hydraulic top or tilt but they are adjustable, I'm still young and strong anyways
You do not NEED top & tilt!
I am 78 and do not need it.
Take a hard look at the Everything Attachments 6 Way Deluxe Scrape Blade.
I have a King Kutter, and another 5' blade, plus the EA blade.
The EA blade is wonderfully superior.
My other two blades will be for sale.
Rippers on a box blade might be helpful if you had a decent base, but you apparently do not.
Consider that over time you may need to buy many loads of crushed stone, to build up your driveway.
You could probably start with 3" minus.
Anything smaller will quickly disappear into your mud.
Steer clear of the TSC stuff.
It is built for price only.
