What is Mulching?
Mulching involves cutting grass into small pieces and redistributing those clippings across the lawn. Instead of bagging them or raking them up, the mower’s blades chop them finely enough to decompose quickly. This process not only saves time but also provides a natural source of fertilizer. Grass clippings are rich in nitrogen and other nutrients essential for healthy grass growth.
Benefits of Mulching
Mulching offers several advantages that can enhance your lawn care routine:
- Reduced Waste: Mulching eliminates the need for bagging clippings, reducing yard waste and the time spent cleaning up.
- Nutrient Recycling: Returning clippings to the soil contributes valuable nutrients, promoting vigorous growth and reducing the need for chemical fertilizers.
- Moisture Retention: The chopped clippings help retain moisture in the soil, reducing the frequency of watering needed.
- Weed Suppression: A layer of fine clippings can inhibit weed growth by blocking sunlight, thus preventing weed seeds from germinating.
How Mulching Works on a Lawn Mower
Most modern lawn mowers can be equipped with mulching capabilities. Here’s how it typically works:
- Mulching Blades: These blades are designed to chop grass finely and create a swirling action that spreads the clippings evenly.
- Deck Design: Mulching mowers often feature a specially designed deck that allows for better airflow, helping to lift grass clippings for more efficient cutting.
- Grass Height: For optimal mulching, it’s advisable to keep your grass at a height of 2.5 to 3.5 inches. Cutting too short can stress the grass and hinder the mulching process.
Choosing the Right Mulching Equipment
When selecting a mower for mulching, consider the following:
- Type of Mower: Both push and riding mowers can be equipped with mulching kits, but the size of your lawn may dictate which type is best for you.
- Mulching Kit: Some mowers require a specific mulching kit to function effectively. The MTD Genuine Parts MTD OEM 19A70041OEM Mulching Kit is tailored for specific models and includes everything needed for a smooth transition to mulching.
- Maintenance: Regular blade sharpening is necessary for effective mulching. Dull blades can tear the grass rather than cut it, leading to less efficient mulching.

What are the disadvantages of mulching?
Mulching has a few downsides. If done improperly, it can lead to thatch buildup, which can harm the lawn. Additionally, during periods of heavy rain, excess clippings can smother the grass. It’s important to monitor conditions and adjust mowing frequency accordingly.
Can all lawn mowers mulch?
Not all lawn mowers come with mulching capabilities. Check your mower’s specifications and consider purchasing a mulching kit, like the one from MTD, to enhance its functionality.
How often should I mulch?
Mulching is best done frequently, ideally every week during the growing season. Keeping clippings short ensures they decompose quickly and don’t overwhelm the lawn.
Is mulching better than bagging?
Mulching is often considered superior because it recycles nutrients back to the lawn, while bagging removes them. However, bagging may be necessary if the grass is too long or wet, as it can lead to clumping.
What height should I keep my grass for mulching?
Maintaining a grass height of 2.5 to 3.5 inches is ideal for mulching. This height allows the grass to thrive while ensuring effective mulching without stressing the plants.
