The satisfying whir of a reel mower across a lush lawn is a testament to the power of a well-maintained tool. But even the most well-built reel mower needs regular attention, particularly to its blades. A dull blade will leave your grass ragged, uneven, and prone to disease. This article will walk you through the process of sharpening a reel lawn mower blade, equipping you with the knowledge and confidence to keep your lawn looking its best.
Overview
Sharpening a reel mower blade is a relatively simple process that can be done at home with a few basic tools. This guide will cover everything from choosing the right tools to understanding the sharpening process itself.
Preparing for the Task
Before you begin sharpening your reel mower blade, it’s crucial to gather the right tools and ensure you have a safe working environment.
1. Essential Tools:
- A sharpening stone: Choose a stone with a coarse grit side for initial sharpening and a fine grit side for honing the edge.
- A flat surface: You’ll need a stable surface to work on, like a workbench or a sturdy table.
- A vise: This will hold your blade securely in place while you sharpen it.
- Protective gear: Wear safety glasses and gloves to protect your eyes and hands.
- Cleaning supplies: You’ll need a cloth or brush to clean the blade after sharpening.
2. Safety First:
- Disconnect the power: If you have a self-propelled reel mower, be sure to disconnect the power source before working on the blades.
- Use caution: Reel mower blades are sharp, even when dull, so handle them carefully.
Removing the Blade
Once you have your tools ready, the first step is to remove the blade from your reel mower. This process might vary slightly depending on your specific mower model, so refer to your owner’s manual if you’re unsure.
1. Identify the Blade:
- The blade is usually located underneath the reel, which is the cylindrical part of the mower that houses the blades.
2. Loosen the Blade Screws:
- There will likely be one or more screws holding the blade in place. Use a suitable screwdriver to loosen these screws.
3. Remove the Blade:
- Once the screws are loosened, gently remove the blade from the reel. Pay attention to how the blade was originally installed, as you’ll need to reassemble it in the same way.
The Sharpening Process
Now that you have the blade removed, it’s time for the actual sharpening.
1. Inspect the Blade:
- Before you start sharpening, carefully inspect the blade for any damage or nicks.
- If the blade is severely damaged, it may be better to replace it rather than attempt to sharpen it.
2. Secure the Blade:
- Use the vise to clamp the blade securely in place, ensuring that the cutting edge is facing upwards.
3. Sharpening with the Coarse Grit Stone:
- Angle: Hold the sharpening stone at a 20-degree angle to the blade, which is the standard angle for reel mower blades.
- Motion: Use a smooth, back-and-forth motion to sharpen the entire length of the blade.
- Pressure: Apply consistent, moderate pressure as you sharpen.
4. Honing with the Fine Grit Stone:
- Once you’ve sharpened the blade with the coarse grit stone, use the fine grit stone to hone the edge.
- Angle: Maintain the same 20-degree angle as before.
- Motion: Use light, gentle strokes to remove any burrs or irregularities on the blade’s edge.
5. Clean the Blade:
- After sharpening, thoroughly clean the blade with a cloth or brush to remove any metal shavings.
Re-installing the Blade
Once the blade is sharp and clean, it’s time to reinstall it on your reel mower.
1. Align the Blade:
- Carefully align the blade with the reel, ensuring that the cutting edge is facing the correct direction.
2. Secure the Blade:
- Tighten the screws that hold the blade in place, ensuring that they are securely fastened.
3. Test the Blade:
- Before mowing, run the reel mower with the blade installed to ensure that it’s working properly.
Maintaining a Sharp Blade
Once you’ve sharpened your reel mower blade, you’ll need to maintain its sharpness to keep your lawn looking its best.
1. Regular Sharpening:
- Sharpness will gradually decline over time, so it’s best to sharpen your blades regularly. Most manufacturers recommend sharpening after every 10-15 hours of use.
2. Avoid Striking Obstacles:
- Striking rocks or other hard objects can dull your blade quickly.
- Use caution when mowing over uneven terrain.
3. Clean the Blade:
- Clean your blade regularly to remove grass clippings and other debris, which can interfere with its performance.

By following this comprehensive guide, you can confidently handle this essential task, ensuring that your reel mower performs at its peak. Remember, a sharp blade is essential for a clean cut and healthy lawn. With a little effort, you can enjoy the smooth, efficient operation of a well-maintained reel mower for years to come.
FAQ
How often should I sharpen my reel mower blade?
Sharpening frequency depends on several factors, including the type of grass, how often you mow, and the quality of your blade. A general guideline is to sharpen the blade every 10-15 hours of use, or when you notice the cut is getting uneven or the grass is being torn instead of cut cleanly.
You can also check for signs of dullness by running your finger along the edge of the blade. If you feel any burrs or rough spots, it’s time for sharpening.
What tools do I need to sharpen a reel mower blade?
You’ll need a few essential tools for the job: a sharpening steel, a flat file, a honing guide (optional), and a wrench to remove the blade. The sharpening steel is used to maintain the primary edge of the blade, while the flat file is used to remove any burrs or imperfections. A honing guide ensures that the blade is sharpened at the correct angle.
If you don’t have a honing guide, you can use a piece of wood or metal with a flat surface to help you maintain a consistent angle while sharpening.
Can I use a bench grinder to sharpen my reel mower blade?
While a bench grinder can be used to sharpen other tools, it’s not recommended for reel mower blades. The high speed and heat generated by a bench grinder can easily damage the temper of the blade, making it brittle and prone to breaking.
Instead, use a sharpening steel and a flat file for a more controlled and precise sharpening process. These tools allow you to maintain the blade’s integrity and ensure a long lifespan.
What is the correct sharpening angle for a reel mower blade?
The ideal sharpening angle for a reel mower blade is around 30 degrees. However, the specific angle can vary depending on the manufacturer’s recommendations and the type of blade you have.
You can find this information in your mower’s manual or by contacting the manufacturer directly. Using the correct sharpening angle ensures a clean, efficient cut and prevents premature wear and tear on the blade.
How do I know when my reel mower blade is sharp enough?
There are a few ways to check if your blade is sharp enough. First, you can hold the blade up to the light and look for a reflection. If the blade is sharp, it should reflect light evenly.
Secondly, you can run your finger (carefully!) along the edge of the blade. If you feel a smooth, sharp edge, you’re good to go. If you feel any burrs or roughness, you need to continue sharpening.
What should I do if my reel mower blade is damaged?
If your blade is damaged, you may need to replace it instead of trying to sharpen it. Look for signs of damage such as chips, cracks, or significant wear.
If the blade is cracked or chipped, it’s unsafe to use and should be replaced immediately. A damaged blade can cause uneven cuts, damage your lawn, and even break during use.
How do I clean and maintain my reel mower blade?
After each use, it’s important to clean your reel mower blade to remove any grass clippings or debris. Use a wire brush or a cleaning cloth to remove any buildup.
You can also apply a light oil to the blade after cleaning to prevent rust and corrosion. Regular cleaning and maintenance will extend the life of your blade and ensure a smooth, efficient mowing experience.
