Great video. It very much reminds me of my younger days. My dad used a beaver-slide stacker until about 1990. I helped with that for many years, until getting married and starting ranching on our own in 1979. Then Peach and I put up loose four-ton stacks with a reversed IHC "M" with a Farmhand F11 loader equipped with a hay head. I used a round cage on wheels for this process. We stacked until 1994, and went to all big round bales at that time.
