To be truthfull with you, I was a little leery of this idea, but he showed the photo to a John Deere dealer, who kept the picture asked quite a few people. One of the person's grandfathers had one. I think they said that the ice was cut, then you put this piece of equipment on the ice, let the lever down to attach to the ice, then they pulled the chunks off with a team of horses..
I know there was a decent size river going thru our farm land.
So I guess this is still a "mystery!"
