Achieving a golf course-quality lawn often hinges on the maintenance of your equipment. The reel mower, a precision cutting tool, requires regular maintenance to perform optimally. Improper bedknife adjustment, a common issue, impacts the cutting ability and highlights the necessity for routine sharpening. Neglecting the process of sharpening reel mower blades can lead to tearing instead of cleanly cutting the grass, promoting disease and hindering lawn health. Mastering the techniques, such as those using a backlapping kit, ensures your lawn stays pristine with minimal effort.

Sharpening Reel Mower Blades Like a Pro: Easy Steps!
This guide provides a step-by-step approach to effectively sharpening reel mower blades, allowing you to maintain a pristine cut for your lawn and extend the life of your mower.
Why Sharpening Reel Mower Blades Matters
A sharp reel mower provides a clean, scissor-like cut, promoting healthier grass and a more aesthetically pleasing lawn. Dull blades tear the grass, making it susceptible to disease and creating a brownish, uneven appearance. Regular sharpening also reduces the strain on your mower, improving its overall performance and longevity.
Signs Your Reel Mower Blades Need Sharpening
Before you begin, determine if your blades actually need sharpening. Look for these telltale signs:
- Torn or frayed grass tips: This is the most obvious indicator.
- Uneven cutting height: Dull blades can cause the mower to skip sections.
- Increased effort to push the mower: Dull blades create more resistance.
- Brownish tint to your lawn shortly after mowing: This indicates damaged grass.
Gathering Your Supplies
Before you start the sharpening process, gather all the necessary tools and materials. This will streamline the process and ensure you have everything you need at hand.
Essential Tools & Materials
- Wrench or Socket Set: To remove and reinstall the reel. Ensure you have the correct size(s) for your mower.
- Flat File: A good quality flat file is essential for shaping the blades.
- Bench Vise (Optional, but Highly Recommended): A vise securely holds the reel, making filing easier and safer.
- Wire Brush: For cleaning the blades and removing debris.
- Gloves: To protect your hands.
- Safety Glasses: Always protect your eyes when working with tools.
- Marking Pen or Sharpie: To mark the starting point.
- Lubricating Oil (Light Machine Oil): For lubricating the reel after sharpening.
- Sharpening Stones (Optional): For honing a finer edge after filing.
Step-by-Step Sharpening Process
This process outlines how to sharpen reel mower blades using a flat file. This is a common and effective method for maintaining a sharp cutting edge.
1. Preparing the Reel Mower
- Safety First! Disconnect the spark plug wire to prevent accidental starting.
- Cleaning: Thoroughly clean the reel blades using a wire brush to remove any grass clippings, dirt, or debris.
- Disassembly (Optional): Some find it easier to sharpen the reel blades after removing the reel from the mower. Refer to your mower’s manual for specific instructions. If you choose to remove the reel, securely clamp it in a bench vise.
2. The Sharpening Process
- Inspection: Carefully examine each blade for damage, such as nicks or deep gouges. If damage is extensive, consider professional sharpening or blade replacement.
- Marking: Use a marking pen to mark the starting point on one blade. This helps you keep track of which blades you have already sharpened.
- Filing: Hold the flat file at the correct angle to match the existing bevel (angle) of the blade. This is crucial for maintaining the proper cutting edge. Gently push the file along the blade, following the existing angle. Avoid applying excessive pressure.
- Consistency: Use smooth, even strokes. Overlap each stroke slightly to ensure consistent sharpening.
- Repeat: Repeat the filing process for each blade, working around the reel.
- Deburring (Optional): After sharpening, use a sharpening stone or fine-grit sandpaper to remove any burrs (small metal fragments) from the cutting edge.
3. Reassembly and Lubrication
- Reassembly (If Disassembled): Carefully reinstall the reel mower according to the manufacturer’s instructions.
- Lubrication: Apply a light coat of lubricating oil to the reel blades and moving parts. This will help prevent rust and ensure smooth operation.
- Testing: Before using the mower on your lawn, test it on a small patch of grass. Ensure it cuts cleanly and evenly. Adjust the cutting height and bedknife as needed.
Maintaining Your Reel Mower Blades
Regular maintenance is key to keeping your reel mower blades sharp and performing optimally.
- Clean After Each Use: Remove grass clippings and debris after each mowing session.
- Inspect Regularly: Check the blades for damage and signs of dullness frequently.
- Sharpen Seasonally: Sharpen your reel mower blades at least once a season, or more often if needed.
- Store Properly: Store your reel mower in a dry, protected area to prevent rust and corrosion.
Troubleshooting
Common Sharpening Issues and Solutions
| Issue | Possible Cause | Solution |
|---|---|---|
| Uneven Sharpening | Inconsistent filing angle or pressure. | Pay closer attention to maintaining a consistent angle and even pressure. |
| Blades Still Dull After Sharpening | Not enough material removed or excessively worn blades. | Continue filing until a sharp edge is achieved, or consider professional sharpening/replacement. |
| Difficulty Rotating Reel After Filing | Tightened too much during reassembly or insufficient lubrication. | Loosen slightly and ensure proper lubrication. Consult the manual for correct torque settings. |
