I've used a bucket to move some snow in the past, but I much prefer an hydraulic angle snow blade up front which is closer in use and concept to a snow pusher than it is to a bucket. The ability to angle the blade while heading down my driveway is essential for me since it allows me to push the snow over the edge of the driveway. A snow pusher would be good in situations where I don't need to direct the snow other than straight ahead, and where there's sufficient space at the end of the push for the snow, which I don't have.
I wonder if there's such a thing as an hydraulic angle snow pusher, which might be the bee's knees.
