Rednecks rejoice… assuming you are a rich redneck. The Dixie Chopper Excalibur 3874 (starting at $11,332) is the worlds fastest lawnmower at 15mph. This beast has a 38hp motor, cuts 9.2 acres per hour, 74-inch mowing deck, and a 12-volt adapter for your cell phone or iPod. I love everything about this gadget. Watch some hilarious videos about the lawnmower after the break.
