What stinks?

I was driving and smelled the typical regions where I travel; paint from a company followed by pasture. The smell of pasture was stronger and fouler and I soon found out why ...

There was a dump truck in the right lane with its back filled high with stuff, like fertilizer or manure and, of course, two dead cows. It was an odd sight, as well as the curious shovel on the side of the dump truck. Something tells me that there were more tools and machinery used to moved the cows than a shovel. Either that or Paul Bunion had children.
