ABSTRACT:
A garden tractor or lawn mower including a belt driven mower blade and an improved tensioning arrangement for the driving belt. The tensioner mechanism provides a first range of tensioning during normal driving loads and a second, more rigid range of tensioning when abnormal loads are encountered so as to reduce belt wear but insure that the belt will not jump off of the driving or driven pulleys.
