Maintaining a lush, healthy lawn requires more than just watering and fertilizing. A sharp reel mower is the key to achieving that pristine, manicured look. But over time, the blades on your reel mower can dull, resulting in a ragged, uneven cut and potentially damaging your grass.
This comprehensive guide will walk you through the process of sharpening a reel mower, from understanding the basics to mastering the techniques. We’ll cover everything from the tools you’ll need to the proper sharpening angles and finishing touches. By the end, you’ll be able to keep your reel mower in top shape, ensuring a consistently smooth and efficient cut for years to come.
Understanding the Importance of Sharp Blades
A sharp reel mower blade cuts cleanly through the grass, leaving a crisp, even cut. This promotes healthy grass growth by minimizing damage to the grass blades. Dull blades, on the other hand, tear and shred the grass, leaving behind a ragged appearance and potentially weakening the plants.
Choosing the Right Sharpening Method
There are two primary methods for sharpening reel mower blades: manual sharpening using a sharpening steel or file and professional sharpening done by a specialized service.
Manual sharpening is a cost-effective and convenient option, especially for minor sharpening needs. However, it requires some practice and patience to achieve a consistent result.
Professional sharpening offers the benefit of expert precision and specialized equipment. This is often the preferred choice for heavily worn blades or for those seeking a perfect, factory-like finish.
Tools for Manual Sharpening
Before you embark on your reel mower sharpening journey, gather the following essential tools:
- Sharpening steel or file: A round or triangular sharpening steel, or a fine-toothed file, will be your primary tool.
- Measuring tool: Use a ruler, caliper, or protractor to ensure you maintain the correct sharpening angles.
- Wooden block or vice: A sturdy base to secure the blade during sharpening.
- Cleaning cloth: For wiping away metal filings and debris.
- Lubricating oil: To reduce friction and prevent rust.
Sharpening the Blades: A Step-by-Step Guide
1. Disassemble the Reel Mower
- Carefully remove the reel from the mower housing.
- Refer to your mower’s instruction manual for specific disassembly procedures.
2. Inspect the Blades
- Examine the blades for any signs of damage, excessive wear, or uneven wear.
- If you notice any major defects, consider having the blades professionally sharpened or replaced.
3. Secure the Blade
- Clamp the blade securely to the wooden block or vice, ensuring it is held firmly.
- The blade should be positioned at a comfortable working angle.
4. Determine the Sharpening Angle
- Consult your reel mower’s manual or the manufacturer’s website for the recommended sharpening angle.
- Most reel mowers use an angle between 25° and 35°.
5. Sharpen the Cutting Edge
- For a sharpening steel: Hold the steel at the recommended sharpening angle and run it smoothly and evenly across the blade, from heel to tip. Apply gentle but firm pressure.
- For a file: Hold the file at the correct angle and move it back and forth across the blade, using short, overlapping strokes.
6. Maintain a Consistent Angle
- It’s crucial to maintain a consistent angle throughout the sharpening process.
- Use a measuring tool to check the angle frequently and adjust as needed.
7. Sharpen Both Sides
- Sharpen both sides of the blade evenly.
- Ensure that the sharpening angle is consistent on both sides.
8. De-burr the Blade
- After sharpening, lightly de-burr the blade edge with a fine-grit honing stone or a leather strop. This removes any sharp edges that could damage the grass.
9. Clean and Lubricate
- Clean the blade thoroughly with a cloth to remove any metal shavings.
- Apply a thin coat of lubricating oil to the blade to prevent rust.
10. Reassemble the Mower
- Carefully reassemble the reel mower according to the manufacturer’s instructions.
- Ensure that all parts are properly aligned.
Maintaining Sharp Blades
- Regular Sharpening: Sharpen your reel mower blades every 5-10 hours of use or as needed, depending on your lawn’s condition and the type of grass you’re mowing.
- Proper Storage: Store your reel mower in a dry, clean environment to prevent rust and damage.
- Avoid Over-sharpening: Sharpening too aggressively can thin the blades and make them more prone to breakage.
Professional Sharpening Services
- If you prefer professional sharpening or if you have heavily worn blades, contact a specialized sharpening service.
- Look for services that specialize in reel mower blades and have a good reputation.
- They will typically have the necessary equipment and expertise to ensure a precise and durable sharpening.
Safety Precautions
- Always wear protective eyewear and gloves when handling sharp tools.
- Be careful when working with the blade, as it can be extremely sharp.
- Take your time and work cautiously to avoid injury.

FAQ
Why should I sharpen my reel mower blades?
Sharpening your reel mower blades is essential for achieving a clean, even cut and maintaining the health of your lawn. Dull blades will tear through grass, leaving behind ragged edges and brown patches. This can lead to disease and weaken the lawn’s ability to thrive. Sharpening the blades ensures a precise cut that promotes healthy growth and a beautiful, lush lawn.
Furthermore, sharpening your reel mower blades will make your mowing experience smoother and more efficient. With sharp blades, you’ll require less effort to push the mower and get the job done. A sharp mower also reduces the risk of scalping your lawn, which can damage the grass and leave unsightly bare patches.
How often do I need to sharpen my reel mower blades?
The frequency of sharpening your reel mower blades depends on several factors, including the type of grass, the frequency of mowing, and the sharpness of the blades themselves. Generally, it’s recommended to sharpen your blades every 10-20 hours of use. However, you should inspect them regularly and sharpen them sooner if they feel dull or you notice an uneven cut.
If you mow frequently or your lawn is thick and tough, you may need to sharpen your blades more often. Similarly, if you’ve recently used your mower to cut through debris or other obstacles, you should check the sharpness of your blades and sharpen them if necessary.
What tools do I need to sharpen my reel mower blades?
To sharpen your reel mower blades, you will need a few essential tools. These include a sharpening stone or file, a flat surface to work on, and a honing guide or jig (optional but recommended). A honing guide or jig helps ensure consistent and precise blade sharpening.
You will also need a screwdriver to adjust the height of the blades and a wrench to loosen and tighten the nuts holding the blades in place. Lastly, it’s helpful to have some lubricating oil for the blade bearings and a cloth to wipe away any debris or oil residue.
What is the best way to sharpen my reel mower blades?
The best way to sharpen your reel mower blades is to use a sharpening stone or file. Start by removing the blades from the mower and cleaning them thoroughly. Then, using the honing guide or jig, clamp the blade securely to the flat surface. Next, use the sharpening stone or file to sharpen the bevel of the blades, ensuring that you maintain a consistent angle.
Work in small, even strokes, and avoid applying too much pressure. You should see a fine, clean edge on the blades after sharpening. Once the blades are sharpened, carefully reassemble them on the mower, adjusting the height and tension as needed.
What are some tips for sharpening my reel mower blades?
Here are a few tips for sharpening your reel mower blades effectively:
- Use a fine-grit sharpening stone or file: This will create a sharp, smooth edge on your blades.
- Sharpen both sides of the blade: Make sure you sharpen both the front and back sides of the blade evenly to ensure a balanced cut.
- Keep the blades clean: Before and after sharpening, wipe down the blades with a clean cloth to remove any dirt or debris.
Following these tips will help you sharpen your reel mower blades effectively and keep your lawn looking its best.
What should I do if my reel mower blades are damaged?
If your reel mower blades are severely damaged, such as cracked, chipped, or bent, you will need to replace them. You can find replacement blades at most lawn and garden stores or online retailers. Be sure to choose blades that are specifically designed for your mower model.
When replacing your blades, make sure you follow the manufacturer’s instructions carefully. Install the blades correctly and adjust the height and tension as needed. You may also need to adjust the reel height to ensure the blades are properly aligned.
How can I tell if my reel mower blades are sharp?
The most reliable way to check if your reel mower blades are sharp is to perform the “paper test.” Simply hold a piece of paper in front of the blades and gently run it across the edge. If the blades cut through the paper easily, they are sharp. If the blades struggle to cut through the paper or tear it, they are dull and need sharpening.
You can also check the sharpness of the blades by looking at the edge. If the edge appears rounded or dull, it’s time to sharpen them. Additionally, if you notice that your mower is pushing harder or leaving behind a ragged cut, it’s a good indication that your blades are dull.
