Driverless John Deere tractor terrorizes Walmart parking lot

The tractor in question wasn't just your regular, run-of-the-mill lawn tractor, either. No, the phantom tractor was a four-wheel-drive Deere equipped with enough snowploughs to clear Vail in January. The tractor spent five minutes jogging circles around the parking lot, gouging the side of the Walmart and annihilating an unsuspecting Suzuki SX4 and Toyota Corolla while slackjawed onlookers stood by doing nothing and area police literally drove in circles.

Eventually, someone with enough conjoins decided to climb aboard the wayward farm machinery and try to stop the madness... but did they succeed?
