One way to achieve a better-looking cut on your lawn is to replace or sharpen your lawnmower blade. It is a good idea to periodically inspect your mower blade. Blades that have chips or bends will need replacing before they cause damage to your lawn or your mower. A Snapper mower blade removes just like any other standard mower blade. You will need to use a block of wood to aid in keeping the blade from moving while you remove the retaining bolt.
Disconnect the mower spark plug wire from the spark plug. Tilt the Snapper mower on its side with the fuel tank pointing up. This will give you access to the mower blade.
Put on a pair of leather work gloves and wedge a piece of wood between the deck of the mower and the mower blade. This will help to keep the blade steady as you remove the securing bolt.
Hold the mower blade with one hand between the center of the blade and the end of the blade. Place a socket wrench on the head of the securing bolt and turn the bolt counter-clockwise.
Remove the securing bolt and pull the blade off the Snapper mower.
