The Beaver is a German made amphibious vehicle. It has power to the two back wheels only. It has two front wheels that are very close together and act as rudders in the water. The most interesting thing about the Beaver is how it goes in reverse. You turn the key clockwise and the engine starts and you go forward. When you need to back up, you turn the engine off and turn the key counter-clockwise and the engine starts BACKWARDS and the machines goes in reverse!
