Thought about one of those, but after this winter Im not sure how well one would work. Usually we push bales around with the front of the tractor and do a decent job of rolling them out, but when it was so bitter cold, snow covered and the outside 3" of bales were frozen solid we couldn't, so it makes me wonder how one works in those conditions.

Ive wondered about taking that style and adding a hydraulic motor to spin them, don't know if it would work or not.
