Made a homemade hillbilly remedy last week, and it worked slick. 5 gallon bucket with the bottom cut off, and sides trimmed down so what was left looked like an ice scooper, in an ice machine.
Attached it to a long aluminum pole, taped a piece of heavy poly to the top rim of the bucket (Dean Nelson above, has a video of this contraption in action). Worked slick. shove it into the bottom end of the drift, and bucket sized and shaped chunks of snow slid out and down.
Now, where do I store this long bastage?
Edit: now that the snow has a crust on it, this bucket-trick ain't so great. The snow is hard. The bucket is not sharp, and due to trying to make it not weigh much - it's kinda flimsy.
I moved about 88 tons of snow off my parents roof last night, with a grain scoop. No fun.
