I have a 7'6" snow pusher, a 7'6" PA plow, and the 66" bucket to choose from. My tractor is 36HP, weighs over 5K with loader, loaded tires, and chains. The snow pusher or the PA plow move the most snow the fastest because they are wider than the bucket. IMO for heavy deep snow you will need lots of weight and power to use a pusher on a long driveway. That much snow in a pusher box will make your tractor work. The angle plow does a good job too but if you angle the blade too much the front of the tractor can get pushed sideways by the snow. I have added a back blading cutting edge on my pusher (not shown in picture) but find I need to make it taller since snow spills over the top of the blade so I have to do two passes when back dragging.
