I have pulled a power auger in a sled while walking. If the sled is a good plastic one it will slide pretty effortlessly without tipping all the time. I sure like a pile of 8 inch holes when you get to where your walking vs the first 2 by hand in a foot or more of ice, then you decide ahhh screw it, 2 is fine
Tried chopping a hole once but the ice was thick. Not a fan of that method.
