The all-wheel drive John Deere, fitted with massive snowplows, circles aimlessly in the parking lot before its trajectory crosses not only into the actual Walmart building but also several cars including a Suzuki SX4 and a Toyota Corolla. 

The dozens of onlookers, plus several police officers, were unable to stop the vehicle. However, it eventually ran into a lamp post where one individual managed to hop on board and save the day.
