I'm not special I'm limited edition
He's cleverer than his name might suggest is that ratty
I had to resort to using a bucket and the exact same technique myself during the last lot of snow we had. I had a vehicle that had come a croppers on a steep hill that was sheet ice. It had come to rest on a narrow ledge and was sat on top of a log with a 2 foot drop to one side and a gate post to the other. The only way I could get enough traction AND the correct angle was to sit my landy at 45 degs to the casualty vehicle on top of another bank. The bank I was on was only 6" wider than my landy and had a 3 foot vertical drop off the side of it and trees all down the other side. The bucket around the tree kept the back of my landy true while I steered my front wheels to compensate as and when required.
