Moving snow with a blade

I've been curious about moving snow with a 3 point blade. In the past I've used 2WD utility tractors and a 6' or 8' boxed scraper (boxed blade) without chains to move snow, but the box quickly fills up and starts piling under the wheels of the tractor, so it's not ideal for large areas or long runs. On the plus side, it's easy to push AND pull snow with a boxed scraper without adjusting anything (since they're designed to push and pull dirt). A lot of the problem is you can't angle a boxed scraper.

How well does it work to turn a 3 pt. blade around backwards and push snow with the blade angled? Seems like this would work well but having never tried it, I'm not sure. Can anyone tell me if there's much difference between pushing and pulling snow with a 3 pt. blade? Seems like your driving wheels would more likely be on cleared pavement if you pushed. Also, do they make hydraulic angling blades that will turn 180 degrees under hydraulic power? I don't imagine they do.

Finally, how do you size a blade to a tractor? I presume you ideally want one that, when angled, is still as wide as your wheel tracks. Or are they simply sized by the HP rating of the tractor? For instance, how big/small a blade would be ideally suited to a 3020? 6 foot? 7 foot? 8 foot?

Sorry for all the novice questions.

Biggest advantage to going backwards is you don't build up a ball of snow in front of the blade that also happens to be under your tractor. You're also not driving over the snow first before trying to shove it with the blade. It really works a lot better going backwards.

Since a little 5' blade is turned about 45 degrees, that's a narrow path of snow you're shoving, so a bigger blade tends to work better for this job. Keeps your tires out of the snow. But then it does an even better job of shoving the tractor sideways, so you're limited this way as well. My old 8N could handle the 5' blade well, and the old Jub could handle the 7' blade.

And if there was much snow at all, the blade was lousy no matter what tractor was pushing it. As soon as you've piled up a few feet of wet snow nothing is going to shove it around worth a darn. Then you need to either use a true snow blade and roll it over, or use a blower and throw it over.
