A dull blade can affect the quality of your cut, leading to uneven grass and potential damage to your lawn. This comprehensive guide will walk you through the process of safely removing the blade from your Craftsman lawn mower, explaining each step in detail for both push and riding mowers.
A Quick Overview
Removing the blade from your Craftsman lawn mower involves several steps. First, you need to disconnect the spark plug wire to prevent accidental starting. Next, you’ll need to locate the blade bolt and use a wrench to loosen it. Once loosened, you can carefully remove the blade while holding the mower firmly to prevent it from falling. Lastly, you’ll need to properly dispose of or store the blade.
Disconnecting the Spark Plug Wire
Before attempting to remove the blade, it is crucial to disconnect the spark plug wire. This simple step will prevent the mower from accidentally starting, ensuring your safety.
Locating the Spark Plug Wire
-
Identify the spark plug: Look for a small, ceramic-like cylinder with a wire attached to it. This is the spark plug, and it’s usually located near the engine’s cylinder head.
-
Locate the spark plug wire: The wire attached to the spark plug is the spark plug wire. It will run from the spark plug to the ignition coil, usually located nearby.
Disconnecting the Spark Plug Wire
-
Unplug the wire: Gently pull the wire connector away from the spark plug. It should come off with a slight tug.
-
Secure the wire: To prevent accidental contact with the spark plug, secure the wire away from the engine using a wire tie or by tucking it behind something.

Use a jack (for riding mowers): If you have a riding mower, lift the mower using a jack to gain access to the underside. Ensure the mower is securely supported on the jack stands.
Removing the Blade Bolt
