How to Keep Grass From Sticking to Lawn Mower Wheels?

Have you ever finished mowing your lawn, only to find your lawnmower wheels plastered with clumps of wet grass? It’s a common frustration, leaving your mower looking messy and potentially hindering its smooth operation. This unsightly and often frustrating situation can be easily avoided with a few simple tricks and a bit of preventative maintenance. This article will delve into the reasons why grass sticks to your mower wheels and provide you with practical solutions to keep your lawnmower wheels clean and free from pesky grass build-up.

The primary culprit behind grass sticking to lawnmower wheels is moisture. When grass is wet, it becomes sticky and readily clings to the surface of the wheels. The combination of wet grass and the friction generated during mowing creates the perfect recipe for a sticky mess.

Understanding the Causes

Understanding the reasons why grass sticks to your mower wheels is crucial to devising effective solutions. Here’s a breakdown of the primary causes:

Wet Grass

As mentioned earlier, wet grass is the main culprit behind sticking. This can occur due to:

  • Recent Rain: A recent downpour can leave your lawn drenched, making the grass susceptible to sticking.
  • Morning Dew: Morning dew, while seemingly insignificant, can contribute significantly to grass sticking to your mower wheels, especially if you mow early in the day.
  • High Humidity: Even without rain, high humidity levels can make the grass blades damp and more prone to sticking.

Wheel Design and Material

The design and material of your lawnmower wheels also play a role:

  • Smooth Surfaces: Wheels with smooth surfaces can offer less resistance to grass, leading to more sticking.
  • Plastic Wheels: Plastic wheels, often found on cheaper mowers, tend to be more susceptible to grass build-up than wheels made of metal or rubber.

Mowing Technique

Your mowing technique can also influence grass sticking:

  • High Blade Height: Mowing with a high blade height can leave more grass on the surface, increasing the chances of sticking.
  • Slow Mowing Speed: Moving your mower slowly allows more time for grass to accumulate on the wheels.

Effective Solutions

Now that we understand the culprits, let’s explore effective solutions to prevent grass from sticking to your lawnmower wheels.

Preventative Measures

  • Time Your Mowing: Try to mow when the grass is dry. This may mean mowing later in the day after the dew has evaporated or waiting until after a recent rain shower has dried.
  • Lower Blade Height: Lowering the blade height can reduce the amount of grass that comes into contact with your mower wheels.
  • Sharpen Your Blades: Sharp blades cut cleanly, reducing the amount of grass that is torn and left on the lawn.
  • Clean Wheels Regularly: After each use, use a brush or cloth to clean the wheels and remove any accumulated grass.
  • Choose the Right Wheels: Consider investing in a mower with wheels made of a material less prone to sticking, like rubber or metal.

DIY Hacks and Solutions

  • Lubrication: Applying a thin layer of silicone spray or dry lubricant to the wheels can create a barrier between the grass and the wheel surface, reducing sticking.
  • Wheel Covers: Use wheel covers designed specifically for lawnmowers. These covers are made of materials like plastic or metal that are less likely to attract grass and can even help to protect your wheels from damage.
  • Grass Catcher: A well-functioning grass catcher can reduce the amount of grass left on the lawn, decreasing the chances of sticking to the wheels.

Maintaining Your Mower for Optimal Performance

Keeping your lawnmower clean and well-maintained is crucial for smooth operation and optimal performance.

Regular Cleaning

  • Clean the Deck: After each use, use a brush or hose to remove any grass clippings or debris from the mower deck.
  • Remove the Grass Catcher: Empty the grass catcher after each use to avoid blockages and to ensure optimal performance.

Regular Maintenance

  • Sharpen Blades: Sharpen your blades regularly (every 2-3 mowings) to ensure clean cuts and prevent damage to your lawn.
  • Check the Air Filter: A clean air filter helps your engine run efficiently and prevents it from overheating.
  • Change the Oil: Follow the manufacturer’s recommendations for oil changes to ensure smooth engine operation.

Conclusion: Keeping Grass Sticking at Bay

Keeping grass from sticking to your lawnmower wheels is a simple task that can be achieved with a few preventative measures and a little bit of maintenance. By understanding the causes and implementing the solutions outlined in this article, you can enjoy a clean and efficient mowing experience. Remember, a well-maintained lawnmower translates to a beautiful lawn and a stress-free mowing experience.


Here are some common questions about keeping grass from sticking to your lawn mower wheels, along with detailed answers:

Why does grass stick to my lawn mower wheels?

Grass sticks to lawn mower wheels due to a combination of factors. First, the blades of grass are often damp, especially after mowing, making them sticky. Additionally, the friction created when the wheels spin against the grass can generate heat, further increasing the stickiness. Finally, the design of some wheels, particularly those with intricate patterns or deep grooves, can create small pockets where grass gets trapped and remains stuck.

What can I do to prevent grass from sticking to my lawn mower wheels?

There are several effective methods to prevent grass from sticking to your lawn mower wheels. One option is to use a lubricant like WD-40 or silicone spray on the wheels and other moving parts. This creates a smooth surface, reducing friction and making it harder for grass to stick. Another effective solution is to regularly clean the wheels after each use, removing any grass clippings or debris that may have accumulated.

Is it necessary to lubricate the wheels every time I mow?

Lubricating the wheels every time you mow is not strictly necessary, but it can be helpful, especially if you live in a humid climate or mow frequently. A single application of lubricant can last for several uses, but it’s a good idea to check the wheels periodically and reapply lubricant if needed. You’ll know it’s time for a reapplication if you notice grass starting to stick again.

Can I use any type of lubricant on my lawn mower wheels?

While WD-40 and silicone spray are popular choices, it’s important to use a lubricant specifically designed for lawn mower wheels. Avoid using oil-based lubricants, as they can attract dirt and debris, making the problem worse. Choose a water-based lubricant that dries quickly and leaves a thin, protective film on the wheels.

What about using a lawn mower with rubber wheels?

Lawn mowers with rubber wheels are often less prone to grass sticking than those with metal wheels. This is because rubber has a smoother surface, creating less friction. However, even rubber wheels can accumulate grass clippings and debris, so regular cleaning is still essential.

What are some other ways to prevent grass from sticking?

Aside from lubrication and cleaning, there are a few other techniques you can try. For example, try mowing in the opposite direction each time, as this can help reduce the amount of grass that gets trapped in the wheels. Additionally, consider using a mulching mower, which cuts the grass into very fine pieces that are less likely to stick to the wheels.

What should I do if grass is already stuck to my wheels?

If grass is already stuck to your lawn mower wheels, try using a brush or a scraper to remove it. You can also try soaking the wheels in soapy water for a few minutes, which can help loosen the grass. If the grass is still stuck, you can use a hairdryer on a low setting to heat the wheels, which can make the grass easier to remove.
