How to Keep Leaves From Blowing Out From Mower Deck

Keeping leaves from blowing out of the mower deck is an important consideration for achieving a clean and efficient mowing experience. This issue can lead to uneven cutting, clumping, and additional cleanup efforts afterward. By understanding the factors that contribute to leaf discharge and implementing practical strategies, you can enhance your mowing routine and ensure a more polished lawn appearance.

In this guide on how to keep leaves from blowing out from mower deck, we will explore various techniques and tips to prevent leaves from escaping the mower deck, helping you maintain a tidy and well-manicured yard.

Why Do Leaves Blow Out From Mower Deck?

Before delving into solutions, it’s essential to understand why leaves may blow out from the mower deck in the first place. The most common reasons include:

Insufficient Mulching Capabilities:

If your mower lacks proper mulching features, such as a mulching blade or kit, it may struggle to break down leaves into smaller pieces. As a result, the larger leaf particles have a higher chance of being discharged out of the mower deck instead of being evenly distributed on the lawn and left to decompose.

Wet Leaves:

Wet leaves can be challenging to mulch effectively, causing them to clump together and clog the mower deck’s discharge chute. This can lead to uneven cutting and potentially ejecting whole leaves from the deck.

Mowing Too Low:

Mowing too low can also contribute to leaves blowing out from the mower deck. When the grass is cut too short, there is less surface area for the leaves to be dispersed evenly, making it more likely for them to escape.

Excessive Leaf Volume:

If you allow too many leaves to accumulate on your lawn before mowing, you may experience issues with discharge. Attempting to mulch a large volume of leaves can overload the mower’s capabilities and result in clumping or blowing out from the deck.

Needed Tools and Materials

To effectively prevent leaves from blowing out of the mower deck, you may need to invest in some tools and materials. These include:

Mulching Blade or Mulching Kit:

A mulching blade or kit is essential for effectively breaking down leaves into smaller pieces to prevent clumping and discharge.

Leaf Blower:

Having a leaf blower on hand can help you clear any remaining leaves from the mower deck after mowing, ensuring a clean finish.

Lawn Bagging System:

If you have an excessive amount of leaves on your lawn, using a bagging system can be an effective way to collect them and dispose of them properly.

8 Simple Step-by-step Guidelines on How to Keep Leaves From Blowing Out From Mower Deck

Step 1: Choose the Right Mower

Selecting the right mower is crucial for effectively managing leaves and ensuring a clean lawn. Look for mowers equipped with strong mulching capabilities, as these are designed to finely chop leaves and grass, allowing for better decomposition and reducing the likelihood of discharge. Consider models that offer adjustable cutting heights, allowing you to modify the mower’s settings according to the density of the leaves on your lawn.

Additionally, choose a mower with a good-sized discharge chute to minimize clumping and allow for better airflow, which helps prevent leaves from blowing out. By investing in a quality mower tailored to handle leaves, you’ll set yourself up for successful yard maintenance.

Step 2: Check the Weather Forecast

Before mowing, it’s important to check the weather forecast to ensure optimal conditions for handling leaves. Rainy or humid weather can lead to wet leaves, which are difficult to mulch and can cause clumping within the mower deck. Ideally, you want to mow when leaves are dry, as they will break down more easily and are less likely to be discharged from the deck.

Additionally, mowing on a dry day will help reduce the chances of turf damage and create a cleaner cut. Being mindful of the weather not only enhances the effectiveness of your mowing session but also contributes to the overall health of your lawn.

Step 3: Adjust Your Mower’s Cutting Height

As mentioned earlier, mowing too low can contribute to leaves blowing out from the mower deck. Before starting your mowing session, adjust your mower’s cutting height to leave a slightly longer blade of grass.

This will provide more surface area for the leaves to be dispersed and minimize their chances of escaping the deck. Additionally, leaving some length on the grass blades helps protect the soil and promote healthy lawn growth.

Step 4: Use a Mulching Blade or Kit 

Utilizing a mulching blade or kit is crucial for optimally managing leaves while mowing. These specialized blades are designed to chop leaves and grass into smaller pieces, enhancing the efficiency of the mulching process. When installing a mulching blade, ensure it fits securely with your mower model for the best performance. The finely chopped material decomposes quickly, enriching the lawn by returning nutrients to the soil instead of cluttering it with whole leaves.

If your mower doesn’t come with a mulching kit, consider purchasing one that is compatible; this can include additional features like baffles that help keep clippings and leaves circulating within the deck longer. This will significantly reduce the likelihood of leaves blowing out while you mow, helping to maintain a manicured appearance across your yard.

Step 5: Mow in a Crisscross Pattern

Mowing in a crisscross pattern, also known as cross-hatching, is an effective technique to avoid clumping and evenly disperse leaves. It involves mowing the lawn in one direction and then going over it again in a different direction, creating intersecting lines like a checkerboard.

This method ensures that leaves are distributed equally throughout the deck and continually mulched until they are small enough to decompose effectively without being blown out of the deck.

Step 6: Remove Excess Leaves Before Mowing 

Before you begin mowing, it’s important to check for an accumulation of excess leaves on your lawn. If you notice a thick layer of leaves, it’s advisable to remove these before mowing to prevent clumping and ensure effective mulching. Use a rake or leaf blower to gather and clear away any large piles of leaves, ideally leaving a thin layer across the lawn.

This step not only facilitates smoother mowing but also allows your mower to function more effectively, ensuring that the remaining leaves are adequately chopped and distributed. By taking the time to prepare your lawn and remove excess debris, you’ll enhance the overall quality of your mowing session and maintain a clean and healthy yard.

Step 7: Check and Clear the Mower Deck Regularly

While mowing, it’s essential to periodically check and clear the mower deck of any excess leaves. This is especially crucial when using a bagging system, as excessive accumulation can compromise the bag’s capacity and affect your mower’s performance. Use a rake or leaf blower to remove any remaining clumps of leaves from the deck, ensuring an uninterrupted mowing session.

Regularly checking and clearing the deck also helps maintain optimal airflow within the mower, reducing discharge and promoting efficient mulching.

Step 8: Dispose of Leaves Properly 

Proper disposal of leaves is crucial for maintaining a clean lawn and preventing potential harm to the environment. If using a bagging system, be sure to dispose of the collected leaves in an appropriate composting or disposal facility.

Alternatively, you can use mulched leaves as organic matter for your lawn or garden beds. Avoid leaving whole leaves on your property as they can suffocate the grass and contribute to thatch build-up.

By following these simple guidelines on how to keep leaves from blowing out from mower deck, you’ll be equipped with the knowledge and tools necessary to effectively manage leaves while mowing and maintaining a beautiful and healthy lawn all year round.

Additional Tips

• Consider using a leaf collection system attachment for your mower if you have a large amount of leaves to manage.
• Be mindful of any obstacles on your lawn, such as rocks or sticks, as they can damage your mower’s blades when mulching leaves.
• Regularly sharpen your mower’s blades to ensure clean and efficient cuts. Dull blades can contribute to clumping and uneven mowing.
• In addition to managing leaves, regular lawn maintenance practices like watering and fertilizing also play a significant role in keeping your lawn healthy and thriving.  So be sure to incorporate these into your lawn care routine for optimal results.
• Remember to always follow safety precautions while mowing, such as wearing proper gear and avoiding mowing on steep slopes. Safety should always be a top priority. Happy mowing!
