To install the new belt place the mower on a flat surface and detach the spark plug wires to prevent the mower from starting. Carefully remove the old belt, and install the new belt in reverse order.
Before changing a belt, the mower should be placed in its lowest cutting position and returned to its resting position after the work is completed. The Simplicity website directs customers to the owner's manual for model-specific instructions for changing their lawn mower belts and provides a link for owners to search for manuals online. Simplicity recommends that an authorized Service Dealer change the belt to ensure that it is installed correctly.
