Murray calls the belt which provides power from the engine to the transmission a "motion belt." This belt receives a lot of wear and tear during normal operation of the lawn tractor and is usually one of the first components of the lawn tractor to fail. The belt is designed to be replaced, not repaired. Most operators can learn how to install a new motion belt when necessary.
