Here's the answer to the question you all have at the tip of your tongue. "What happens to all the combine poop?" It gets baled and sold as straw. This is a bale stacker collecting bales from the field. This guy is working with three balers. That seems to be about the right combination for this group. The stacker takes the bales and makes a stack of them. Later on a loader and giant flat bed truck come and pick up the bales.
