Abstract
A belt tensioning assembly that simultaneously controls belt tension and belt drive speed is provided. A pivotable bracket is pivotably attached to a lawn mower or other light duty, belt driven equipment. A variable speed pulley for holding a pair of rotatable belts is attached to a slide bracket and the slide bracket is slidably attached to the pivotable bracket. A spring or other biasing mechanism can be used to connect the slide bracket to the pivotable bracket to maintain substantially constant belt tension.
