I work at an auto parts store that is across the street from a huge agricultural equipment lot and they have some amazing machines over there. I am am talking about the serious combines, harvesters, and irrigation systems that they use to maintain the most massive farms.
I have talked to the guys over there a few times and it is serious stuff. It makes a car look like a little toy. I would love to give one of the big combines a test drive, but for obvious reasons they won't let me.
