Step-by-Step Guide to Removing the Blade
Now, let’s delve into the process of removing the blade:
- Locate the blade bolt: This is typically found in the center of the blade, underneath the mower deck.

Important Tips for Blade Removal:
- Avoid using a hammer: Striking the blade can damage it, so use a wrench to tighten and loosen the bolt.
- Mark the blade’s position: If you’re just sharpening the blade, make a mark on the blade and the mower deck to ensure correct reinstallation.
Re-installing the Blade: Ensuring Proper Alignment
Once you’ve cleaned or sharpened the blade, it’s time to reinstall it:
- Align the blade with the mounting holes: Ensure the blade is correctly positioned with the mounting holes on the mower deck.
- Tighten the blade bolt: Use the socket wrench to secure the blade bolt, ensuring it’s tight enough without overtightening.
- Check the blade’s spin: Start the engine briefly (without engaging the blades) to check if the blade spins freely and without any wobble.
Tips for Correct Re-installation:
- Torque specifications: Check your owner’s manual for the recommended torque setting for your Craftsman lawnmower blade bolt.
- Balancing: If the blade isn’t balanced, it can vibrate and damage the mower. A local lawnmower repair shop can help you balance the blade if necessary.
Troubleshooting Common Problems
Here are some common issues you might encounter and how to address them:
Blade Bolt Won’t Loosen
- Use a breaker bar: If the bolt is exceptionally tight, try using a breaker bar for extra leverage.
- Apply penetrating oil: Spray penetrating oil onto the bolt and let it sit for a few minutes to help loosen it.
Blade is Stuck
- Tap gently with a rubber mallet: If the blade is stuck, you can gently tap the back of the blade with a rubber mallet to free it.
Blade Won’t Spin Correctly
- Check for debris: Ensure there’s no debris or grass clippings preventing the blade from spinning freely.
- Inspect the blade for damage: If the blade is bent or damaged, it needs to be replaced.
