Has anyone tried setting up a rear blade with a hydraulic motor for 360-degree rotation? Or does this fall into the "dumb idea" category.

would potentially work with motor that is large enough to with stand torque demands or like Peter states some mechanical lock or brake to hold position.

That’s exactly how the blade on an actual road grader rotates. The downside is the cost to build something like that would be substantial.
It’s possible

I hope you find this an interesting story and project, it has many different paths along the way that lead to an incredible friendship and collaborative effort. If it were not for an interesting turn of events, the results of what you are about to see would not have been possible - This will...

You would have to build it like a turn table on a track hoe. Which is probably like a motor grader is made.

Thank you for your comments everyone. I had a feeling the forces on the hydraulic motor could be an issue. D & D, I hope your project turns out well after all the thought you've put into it. Like you, I'm tired of getting on/off the tractor to adjust the blade. Would be really nice to adjust it in each direction and angle from the tractor seat when snowplowing driveways.

How often do you need 360° rotation? Are you switching between pushing and pulling a lot?
90° rotation (+45°, -45°) would be easy enough with hydraulic cylinders. Then a pin would allow you to reverse it, but that would require leaving the seat.
There are probably a few ways to achieve the 360° rotation. Perhaps a large rotating table plus a large ring and pinion gear.
I'm not sure what would be able to donate a ring and pinion. A typical starter motor ring and pinion likely wouldn't be sturdy enough. Are there drive gears for a small dozer?
Perhaps head to a tractor recycler and see what strikes your fancy. Good heavy duty hub + the ring and pinion.
I like the idea of looking for a scrap small grader, or scrap mini excavator.

Somebody posted a link to TractorHouse a couple of days ago. Quite a resource.
Parting out mini excavators. They may have the parts you'd need.
