3. Blade Types and Characteristics
Understanding different blade types can help optimize mowing performance. The Stens 362-627 is a toothed/mulching blade. Other common blade types include notched/rolled hi-lift and flat/low-lift blades.
3.1. Toothed/Mulching Blades (Stens 362-627)
Toothed or mulching blades are designed to cut grass into finer clippings. This design helps to return nutrients to the lawn, promoting a healthier and more manicured appearance. They are particularly effective for mulching applications.

3.2. Notched/Rolled Hi-Lift Blades
Notched or rolled hi-lift blades are designed to create a strong airflow under the mower deck. This airflow lifts the grass blades for a clean, even cut and then propels the clippings into a bagger more effectively. They are often preferred for lawns with fine grass where bagging is common.
3.3. Flat/Low-Lift Blades
Flat or low-lift blades create less suction and are ideal for dry, sandy, or coastal lawns. Their design minimizes the amount of sand or debris thrown by the blade, protecting the mower deck and reducing wear. Some low-lift blades are reversible, offering extended blade life.

4. Installation
Proper installation of the blade is crucial for safety and optimal performance. Always refer to your mower's specific owner's manual for detailed instructions and safety precautions before attempting any maintenance or installation.
4.1. Safety Precautions
- Ensure the mower engine is off and cool.
- Disconnect the spark plug wire to prevent accidental starting.
- Wear heavy-duty gloves to protect your hands from sharp blade edges.
- Use appropriate tools for loosening and tightening bolts.
- Secure the mower to prevent it from moving or tipping during blade removal/installation.
4.2. Blade Removal
- Tilt the mower onto its side, ensuring the carburetor and air filter are facing upwards to prevent fuel or oil leaks.
- Use a block of wood or a specialized blade removal tool to brace the blade and prevent it from turning.
- Loosen the blade bolt(s) using a wrench or socket. Note the direction of rotation for removal (typically counter-clockwise).
- Carefully remove the old blade, noting the orientation of any washers or spacers.
4.3. Blade Installation
- Clean the blade mounting area on the mower deck and spindle.
- Position the new Stens 362-627 Toothed Blade with the cutting edge facing the correct direction (usually indicated by an arrow on the blade or the mower deck). The teeth should point upwards towards the mower deck.
- Reinstall any washers or spacers in their original positions.
- Tighten the blade bolt(s) securely to the manufacturer's recommended torque specifications. Use a torque wrench if available.
- Ensure the blade is properly seated and does not wobble.

5. Operation
Once the blade is installed, ensure all safety guards are in place before operating the mower. The Stens 362-627 Toothed Blade is designed for mulching, which means it cuts grass into small pieces that are returned to the lawn. For optimal mulching, avoid cutting wet or excessively tall grass.
6. Maintenance
Regular maintenance of your mower blade ensures safety, efficiency, and extends the life of the blade and your mower.
6.1. Inspection
Before each use, inspect the blade for:
- Sharpness: A dull blade tears grass, leading to an unhealthy lawn.
- Damage: Check for bends, cracks, or excessive nicks. A damaged blade can cause vibrations and be dangerous.
- Balance: An unbalanced blade can cause excessive vibration, leading to premature wear on engine components.
6.2. Cleaning
After each use, clean grass clippings and debris from the blade and the underside of the mower deck. This prevents buildup that can reduce cutting efficiency and promote rust.
6.3. Sharpening
Sharpen the blade regularly, or as needed, to maintain a clean cut. Use a blade sharpener or file, maintaining the original blade angle. Ensure the blade remains balanced after sharpening.

7. Troubleshooting
If you experience issues with your mower's cutting performance after installing the Stens 362-627 blade, consider the following:
- Uneven Cut: Check if the blade is installed correctly, if it's bent, or if the mower deck is level.
- Excessive Vibration: This often indicates an unbalanced or bent blade. Remove and inspect the blade for damage or ensure it is properly balanced.
- Poor Mulching: Ensure the blade is sharp and the grass is dry. Cutting excessively tall or wet grass can hinder mulching effectiveness.
- Blade Not Spinning: Check for obstructions under the deck or issues with the spindle assembly or belt.
