  • Patent number: 8628034
    Abstract: A belt tensioning system configured to more effectively maintain the proper tension in a belt that can be engaged and disengaged. Proper tension in the belt is maintained even if the belt stretches or contracts by including a spring biased member between a tension wheel and a pivot frame. The spring member is preloaded such that when the belt stretches the tension wheel is biased against the belt by the force of the spring. Also, by selectively engaging the tension system one can avoid overloading the engine without the need to incorporate a clutch.
