Maintaining a pristine lawn is a rewarding endeavor, and for many, a reel mower is the tool of choice for achieving that classic, manicured look. Unlike rotary mowers that chop grass with a spinning blade, reel mowers use a scissor-like action, cleanly slicing each blade of grass. This results in healthier grass and a more aesthetically pleasing lawn. However, the effectiveness of a reel mower hinges on the sharpness of its blades. So, how often do you really need to sharpen those blades to keep your lawn looking its best? The answer, as you might suspect, isn’t a simple one.
Understanding the Importance of Sharp Reel Mower Blades
A sharp reel mower blade is the cornerstone of a healthy and beautiful lawn. Dull blades don’t cut; they tear and shred the grass. This tearing action leaves ragged edges that turn brown and become susceptible to disease and pests. Sharp blades, on the other hand, provide a clean, precise cut that promotes healthy growth, reduces water loss, and minimizes the risk of lawn problems.
Think of it like using a sharp knife versus a dull one in the kitchen. A sharp knife slices cleanly through a tomato, leaving a smooth, intact surface. A dull knife crushes and tears the tomato, making it look messy and unappetizing. The same principle applies to your lawn.
Furthermore, a reel mower with sharp blades requires less effort to push. Dull blades increase resistance, making the mowing process more strenuous and time-consuming. You’ll find yourself working harder to achieve subpar results.
Factors Influencing Sharpening Frequency
Several factors determine how often you need to sharpen your reel mower blades. These include the type of grass you’re cutting, the size of your lawn, the frequency of mowing, and the presence of abrasive materials in your yard.
Grass Type
Different types of grass have varying levels of toughness and abrasiveness. Coarse grasses like Zoysia and St. Augustine will dull mower blades more quickly than fine grasses like Fescue or Ryegrass. The tougher the grass, the more frequently you’ll need to sharpen your blades. Regularly mowing these coarser grasses will necessitate more frequent sharpening.
Lawn Size
The size of your lawn directly correlates with the amount of use your reel mower receives. A larger lawn means more cutting, which translates to more wear and tear on the blades. If you have a sprawling estate, you’ll likely need to sharpen your blades more often than someone with a small urban lawn.
Mowing Frequency
The more frequently you mow, the less stress you put on your mower blades with each individual cut. Cutting grass regularly, before it becomes too long and thick, is easier on the blades than allowing the grass to grow excessively long and then hacking it down. However, even with frequent mowing, blades will still dull over time, so regular inspection is essential.
Abrasive Materials
The presence of sand, dirt, rocks, and other debris in your lawn can significantly accelerate the dulling process. These materials act like sandpaper, grinding down the edges of the blades each time they come into contact. Make an effort to remove these materials from your lawn before mowing to prolong the life of your blades. Remove rocks and debris before mowing to prevent damage and extend blade sharpness.
Identifying the Signs of Dull Blades
Knowing when to sharpen your reel mower blades is crucial for maintaining a healthy lawn. Here are some telltale signs that your blades are in need of sharpening:
- Torn or Ragged Grass Blades: This is the most obvious sign. If you notice that your grass blades have frayed or ripped edges after mowing, your blades are likely dull.
- Brown Tips: Dull blades tear the grass instead of cutting it cleanly, resulting in brown tips that give your lawn an unhealthy, stressed appearance.
- Increased Effort to Push the Mower: If you find yourself struggling to push the mower, even on level ground, dull blades may be the culprit.
- Uneven Cut: Dull blades can cause an uneven cut, leaving some areas of your lawn higher than others.
- Visible Damage to Blades: Inspect your blades regularly for nicks, dents, or other damage. Any visible damage can affect the blades’ cutting ability.
- Duller Sound: A sharp reel mower will make a distinct “snapping” sound as it cuts the grass. If the sound is duller or more of a “thud,” it’s time to sharpen the blades.
General Sharpening Guidelines
While the specific factors mentioned above influence sharpening frequency, here are some general guidelines to follow:
- For lawns with fine grasses and minimal debris: Sharpen your blades at least once a season, or every 25-50 hours of use.
- For lawns with coarse grasses or frequent debris: Sharpen your blades more frequently, perhaps every 20-30 hours of use, or even more often if you notice signs of dullness.
- New mowers: Sharpen blades after the first few uses as a precautionary measure.
- Professional lawn care: Lawn care professionals with large lawns and frequent mowing may need to sharpen blades weekly or even daily.
A good rule of thumb is to inspect your blades every few weeks and sharpen them whenever you notice signs of dullness. This proactive approach will ensure that your lawn always looks its best.
Sharpening Methods: DIY vs. Professional
You have two main options when it comes to sharpening your reel mower blades: doing it yourself or hiring a professional. Each option has its pros and cons.

How do I know when my reel mower blades need sharpening?
Several indicators suggest your reel mower blades need sharpening. A key sign is the grass being torn or ripped rather than cleanly cut. This will appear as frayed or brownish tips on the grass blades, indicating a dull blade struggling to make a clean slice. You may also notice the mower requires more effort to push or pull, and it might leave uncut patches, especially with thicker grass types.
Another telltale sign is the increased noise produced by the mower during operation. Dull blades create more friction as they struggle through the grass, leading to a louder, rasping sound. Additionally, a visual inspection of the blades can reveal rounded edges or nicks that prevent a clean cut. If you observe any of these signs, it’s time to consider sharpening your reel mower blades.
What factors influence how frequently I need to sharpen my reel mower blades?
The frequency of sharpening reel mower blades depends on several variables. The type of grass you’re mowing significantly impacts blade wear. Coarse grasses like St. Augustine or Zoysia will dull blades faster than finer grasses like Fescue or Kentucky Bluegrass. The size of your lawn and the frequency with which you mow also play a role – larger lawns and more frequent mowing mean more wear and tear on the blades.
Furthermore, the presence of debris, such as rocks, sticks, and sand, in your lawn will drastically accelerate blade dulling. Even small objects can cause nicks and damage, necessitating more frequent sharpening. Finally, the quality of the blades themselves affects their longevity. Higher-quality, hardened steel blades will retain their sharpness longer than cheaper alternatives. Regular cleaning and proper storage can also help extend the lifespan of your blades and reduce the need for frequent sharpening.
Can I sharpen my reel mower blades myself, or should I hire a professional?
Whether you can sharpen your reel mower blades yourself depends on your skill level and the tools you have available. If you are comfortable with hand tools and have some mechanical aptitude, you can sharpen your blades using a backlapping kit or a file. Backlapping involves using an abrasive compound to grind the blades against the bedknife, effectively sharpening the cutting edges. Filing requires a specific type of file and a steady hand to maintain the correct angle.
However, if you are unsure of your abilities or lack the necessary tools, it is best to hire a professional. A professional sharpening service will have specialized equipment and expertise to ensure the blades are sharpened correctly, maintaining the proper angle and balance. Improper sharpening can damage the blades or the mower itself, leading to costly repairs. Consider your comfort level and the potential risks before deciding whether to tackle the job yourself.
What is “backlapping,” and how does it sharpen reel mower blades?
Backlapping is a sharpening method specifically designed for reel mowers. It involves applying an abrasive compound, typically a gritty paste, to the reel blades and then running the reel mower in reverse. This process effectively grinds the blades against the bedknife, which is the stationary blade that the reel blades cut against. The abrasive compound removes small amounts of metal, restoring a sharp cutting edge to both the reel blades and the bedknife.
The key to successful backlapping is ensuring even distribution of the abrasive compound and running the mower in reverse for the appropriate amount of time. Regular backlapping, performed every few weeks during the mowing season, can significantly extend the life of your reel mower blades and maintain optimal cutting performance. It’s a relatively simple process that can save you time and money compared to more intensive sharpening methods or professional services.
How often should I backlap my reel mower blades?
The frequency of backlapping your reel mower blades depends on how often you use the mower and the conditions in which it operates. As a general guideline, backlapping every 20-25 hours of mowing is a good starting point. This translates to roughly every 2-4 weeks for most homeowners who mow their lawns regularly during the growing season.
However, if you notice your mower starting to tear the grass or requiring more effort to push, it’s a sign that the blades are dulling and need backlapping sooner. Similarly, if you frequently mow over debris or have a particularly coarse type of grass, you may need to backlap more frequently. Observing the performance of your mower and adjusting the backlapping schedule accordingly will ensure optimal cutting performance.
What tools are needed for sharpening reel mower blades at home?
Sharpening reel mower blades at home requires a few essential tools. For backlapping, you’ll need a backlapping kit, which typically includes an abrasive lapping compound, a brush or applicator, and sometimes a backlapping adapter. A pair of work gloves is also recommended to protect your hands from the abrasive compound.
If you choose to sharpen with a file, you’ll need a specialized reel mower blade file. This type of file is designed with the correct angle and shape for sharpening reel blades. Additionally, you’ll need a vise to securely hold the blade during filing, and a wire brush to clean the blades before and after sharpening. Eye protection is crucial in both methods to prevent debris from entering your eyes.
What are some tips for maintaining my reel mower blades to prolong their sharpness?
Several proactive steps can help prolong the sharpness of your reel mower blades and reduce the frequency of sharpening. Regularly cleaning your mower after each use is crucial. Removing grass clippings, dirt, and debris prevents corrosion and keeps the blades free from obstructions that can cause premature dulling. A simple brush and hose can suffice for this task.
Avoid mowing over rocks, sticks, and other debris that can nick or damage the blades. Rake your lawn regularly to remove these objects before mowing. Proper storage is also essential. Store your reel mower in a dry place, away from moisture and direct sunlight, to prevent rust and corrosion. Consider lubricating the blades periodically with a light oil to further protect them. These simple practices can significantly extend the life of your reel mower blades.
