3. Using a wrench or socket, turn the blade bolt counter-clockwise to loosen and remove it. Note that some mowers may have left-hand threads, requiring clockwise rotation to loosen.
4. Carefully remove the old blade and any washers or spacers. Note their orientation for reinstallation.

3.3 Installing the New Blade

1. Inspect the blade mounting area on the mower shaft for any debris or damage. Clean as necessary.
2. Position the new MaxPower 331737B mulching blade onto the mower shaft. Ensure the cutting edges (the angled side of the blade) are pointing upwards towards the mower deck. The curved "wings" of the blade should also point upwards.
3. Align the center hole and any alignment pins on the blade with the corresponding features on the mower shaft.
4. Reinstall any washers or spacers in their original orientation.
5. Insert the blade retaining bolt and tighten it clockwise (or counter-clockwise for left-hand threads) using a wrench. Use the block of wood or blade tool to brace the blade.
6. Tighten the bolt securely to the manufacturer's recommended torque specifications, if available. Over-tightening or under-tightening can cause issues.
7. Reconnect the spark plug wire before attempting to start the mower.
