Abstract
A belt-tensioning device for a walk-behind mower with driven wheels is disclosed. The belt-tensioning device allows the operator a hands-free way to increase the idler pulley force and hence, tension of the driven belt. The device includes a belt guard, a spring adjuster assembly comprising a spring adjuster arm and a spring adjuster footstep. The operator increases the tension of the driven belt by using the footstep that is located on the device attached to the spring adjuster arm. This moves the pulley by way of a spring attached to the pulley and the belt guard. Movement of the spring increases the belt tension.
