Just kidding on the combine harvester. Although that does showcase MY expanded truck/tractor vocabulary! Actually, if he sees a combine harvester he calls it "Frank." Which is the name of the harvester in the movie Cars (you know, the tractor tipping scene...) I'm sure I'm forgetting a handful of others that he knows but that's a good sample what comes to mind. What can I say? He likes trucks!
