I had the mixer wagon as we had silage put up for a few years. It was the best way to make use of the fall rye that I was growing and it was the best way to get the hay put up the year I broke my arm pretty bad. I would hire a big tub grinder to come in and chop hay to mix the silage down. It got harder to find a silage crew and one that wanted to bag it was impossible. It didn't make sense to keep tub grinding hay with no silage so I just switched back to a bale processor to feed the bunk. I also quit growing fall rye. :?
I didn't know if there was any custom tub grinders around anymore but saw 2 moving down the highway the other day. The one Mighty Giant one was working at the feedlot about forty miles from me.
I guess that iron has a purpose but backgrounding my calves works with the feed box on the pick up for pellets and the bale processor or bale grazing work fine for me.
I do have a pretty good Big Auggie 14 for sale.
It did work nice for one pass feeding of pellets or grain, hay and silage.
I also mixed my mineral right in with the batch.
