Maintaining a reel mower is crucial for achieving that pristine, golf course-like lawn. One common question that arises is whether WD-40 can be used as part of the maintenance routine. The answer is nuanced, and understanding the properties of WD-40 and the specific needs of a reel mower is key.
Understanding WD-40: More Than Just a Lubricant
WD-40 is a ubiquitous household product, renowned for its versatility. However, its primary function is not actually as a long-term lubricant. WD-40 is a water displacement formula (hence the “WD” in its name), designed to drive out moisture and prevent rust. It also acts as a solvent, helping to loosen stuck parts and clean surfaces.
The Composition of WD-40
The exact formula of WD-40 is proprietary, but its main components include:
- Mineral spirits: A solvent that helps dissolve grease and grime.
- Aliphatic hydrocarbons: Contribute to the water displacement properties.
- Petroleum oil: Offers some lubrication.
- Carbon dioxide: Used as a propellant.
While it does provide some lubrication, the petroleum oil content is relatively low, and it’s not designed for long-lasting lubrication under heavy loads or high friction.
What WD-40 Does Well
WD-40 excels at:
- Displacing moisture to prevent rust and corrosion.
- Loosening rusted or stuck parts.
- Cleaning surfaces by dissolving grease, grime, and adhesives.
- Providing short-term lubrication.
Reel Mower Maintenance: A Detailed Look
Reel mowers, with their intricate cutting mechanisms, require regular and specific maintenance to ensure optimal performance and longevity. Unlike rotary mowers, which rely on a spinning blade, reel mowers use a scissor-like action between a rotating reel of blades and a stationary bedknife.
Key Components of a Reel Mower Requiring Maintenance
The main components that need regular attention are:
- Reel blades: These blades must be sharp and properly adjusted to ensure a clean cut.
- Bedknife: The stationary blade against which the reel blades cut. It needs to be sharp and aligned correctly.
- Bearings: Bearings allow the reel to rotate smoothly. They need to be properly lubricated to prevent wear and tear.
- Chain/Gears: Many reel mowers use chains or gears to transfer power from the engine or human power to the reel. These components require lubrication.
- Adjustment Mechanisms: These mechanisms control the height of cut and the alignment of the reel and bedknife. They need to be free of rust and corrosion.
The Importance of Proper Lubrication
Proper lubrication is paramount for a reel mower’s performance. Insufficient lubrication can lead to:
- Increased friction and wear on moving parts.
- Reduced cutting efficiency.
- Overheating and potential damage to bearings and other components.
- Increased effort required to push or operate the mower.
Using the correct type of lubricant is just as important as lubricating regularly.
WD-40 and Reel Mowers: When to Use It and When to Avoid It
Now, let’s address the core question: can you use WD-40 on a reel mower? The answer is both yes and no, depending on the specific application.
When WD-40 is Acceptable for Reel Mowers
WD-40 can be beneficial in certain situations:
- Cleaning: WD-40 is excellent for cleaning accumulated grass clippings, dirt, and grime from the reel blades, bedknife, and other external parts. Its solvent properties help dissolve stubborn residue.
- Rust Prevention: Applying a light coat of WD-40 to the reel blades and bedknife after cleaning can help prevent rust and corrosion, especially during storage.
- Loosening Stuck Parts: If you encounter any rusted or stuck adjustment mechanisms, WD-40 can help loosen them. Allow it to penetrate for a few minutes before attempting to move the parts.
When WD-40 is Not Recommended for Reel Mowers
There are situations where using WD-40 on a reel mower is not advisable:
- As a Primary Lubricant: WD-40 is not a suitable long-term lubricant for the reel mower’s bearings, chains, or gears. Its lubricating properties are limited, and it can attract dirt and grime, which can exacerbate wear and tear. Using it as a primary lubricant will likely lead to premature failure of these components.
- On Cutting Surfaces During Operation: Applying WD-40 to the reel blades or bedknife just before or during mowing is not recommended. It can leave a residue that attracts grass clippings and can affect the quality of the cut. It can also potentially harm the grass.
- Instead of Proper Grease: Components requiring grease, like bearings, should receive proper grease application, not WD-40. Grease is designed to provide long-lasting lubrication under pressure and prevent water ingress. WD-40 cannot fulfill this function.
Alternatives to WD-40 for Reel Mower Maintenance
For long-term lubrication and optimal performance, it’s essential to use the right products for reel mower maintenance. Here are some alternatives to WD-40:
Recommended Lubricants for Reel Mowers

Use WD-40 primarily for cleaning, rust prevention, and loosening stuck parts. Always prioritize proper lubrication with appropriate lubricants to ensure the longevity and optimal performance of your reel mower. By following these guidelines, you can keep your reel mower in top condition and enjoy a beautifully manicured lawn for years to come. Remember to always consult your owner’s manual for specific maintenance recommendations for your model.
Is WD-40 generally recommended for lubricating reel mowers?
WD-40 is not generally recommended as a primary lubricant for reel mowers. While it can be effective as a penetrating oil to loosen rusted or stuck parts, its lubricating properties are quite light and short-lived. Relying solely on WD-40 for lubrication on a reel mower will likely lead to premature wear and tear on the blades and other moving components, resulting in a less efficient cut and a shorter lifespan for your mower.
Instead, consider WD-40 more of a cleaning agent or rust preventative. Following its use, particularly after freeing stuck components, it’s crucial to apply a proper, heavier lubricant specifically designed for metal-on-metal contact. This ensures the reel mower operates smoothly and is adequately protected from friction and wear during use. Always consult the manufacturer’s recommendations for the best type of lubricant for your specific reel mower model.
Can WD-40 be used to clean a reel mower?
Yes, WD-40 can be used to clean a reel mower effectively. Its solvent properties help dissolve dirt, grime, and old grease, making it easier to wipe away debris from the blades, rollers, and other parts of the mower. Spraying WD-40 on the components, letting it sit for a few minutes, and then wiping it clean with a cloth can significantly improve the mower’s overall cleanliness and performance.
However, remember that WD-40 leaves behind a thin film that, while protective against rust, isn’t a long-term lubricant. After cleaning with WD-40, always follow up with an application of a dedicated lubricant designed for reel mower components to ensure smooth operation and prevent wear. This two-step process – cleaning then lubricating – provides optimal maintenance for your reel mower.
What are the downsides of using WD-40 as the sole lubricant on a reel mower?
The primary downside of using WD-40 as the sole lubricant is its lack of long-lasting lubrication. Its light formula evaporates relatively quickly, leaving the metal parts vulnerable to friction and wear. Over time, this can lead to a dulling of the blades, increased resistance during mowing, and eventually, damage to the mower’s internal components.
Furthermore, WD-40 can attract dust and dirt, creating a gummy residue that can further impede the mower’s movement. This residue acts like an abrasive, accelerating wear and tear instead of preventing it. A dedicated lubricant is designed to provide a protective barrier against these elements and maintain smooth, efficient operation for an extended period.
What type of lubricant should I use on my reel mower instead of WD-40?
Instead of WD-40, use a lubricant specifically designed for metal-on-metal contact and outdoor equipment. Options like lithium grease, silicone lubricants, or even certain types of motor oil (depending on manufacturer recommendations) are far better choices. These lubricants are thicker and more durable than WD-40, providing a longer-lasting layer of protection against friction and corrosion.
Look for lubricants that are water-resistant or waterproof, especially if you frequently mow damp grass. Also, consider the manufacturer’s recommendations in your reel mower’s manual; they often specify the ideal type of lubricant for your particular model. A well-chosen lubricant will significantly extend the life and improve the performance of your reel mower.
Can WD-40 help prevent rust on a reel mower?
Yes, WD-40 can help prevent rust on a reel mower, albeit as a temporary solution. It forms a thin, water-displacing barrier that protects the metal surfaces from moisture, one of the primary causes of rust. Regularly applying a light coat of WD-40 to exposed metal parts, especially after cleaning, can help keep rust at bay.
However, WD-40’s rust-preventative properties are not as long-lasting as dedicated rust inhibitors or protective coatings. For long-term rust prevention, consider applying a specialized rust-proofing product. If you use WD-40, reapply it frequently, especially after using the mower in wet conditions or after cleaning it with water.
How often should I lubricate my reel mower?
The frequency of lubrication depends on how often you use your reel mower and the conditions it operates in. As a general guideline, lubricate the moving parts every 2-4 weeks during the mowing season if you use it frequently (once or twice a week). If you use it less often, lubricating it once a month might suffice.
However, always inspect your mower before each use and lubricate any areas that appear dry or stiff. Pay particular attention to the reel blades, rollers, and any other moving joints. Proper and regular lubrication will ensure smooth operation, reduce wear, and prolong the life of your reel mower. Always refer to your owner’s manual for specific recommendations.
How should I apply WD-40 (or other lubricant) to my reel mower effectively?
To apply WD-40 (or any lubricant) effectively, start by cleaning the area you intend to lubricate. Remove any dirt, grass clippings, or old grease to ensure the lubricant can properly adhere to the metal surface. A clean surface allows for optimal penetration and lubrication.
Apply the lubricant sparingly but thoroughly, focusing on moving parts like the reel blades, rollers, and pivot points. After application, rotate the reel and move the components to distribute the lubricant evenly. Wipe away any excess lubricant to prevent it from attracting dirt and grime. Remember, a little goes a long way when it comes to lubrication.
