What is a Mulching Lawn Mower?

A mulching lawn mower is a type of lawn mower that cuts up the grass clippings you mow and deposits them back into the soil, removing the need for bagging. Bagging and disposing of your grass clippings has always been the most tedious part of the lawn care process. A lawn mower that saves you time and helps your lawn’s health sounds good, right?

A mulching lawn mower does exactly just that! By using lawn mowers that mulch leaves, you can improve your soil's fertility and minimize erosion, according to the Bulletin of the National Research Centre. Mowrator has outlined how lawn mowers with mulching blades work, its benefits, and the best way to mulch your garden.

Key Takeaways

  • Mulching lawn mowers use specially designed blades and deck shapes to finely chop grass clippings and return them to the soil as a natural fertilizer.
  • This process improves soil health, retains moisture, moderates soil temperature, and releases nutrients over time.
  • Mulching fosters beneficial insect habitats, reduces water runoff, and can lower overall environmental impact.
  • Using a mulching mower saves time and effort by eliminating the need to bag or remove clippings, promoting a lush and healthy lawn.

How do Mulching Lawn Mowers work?

How do Mulching Lawn Mowers work

Mulching lawn mowers use a sophisticated combination of components that can cut grass multiple times before the grass clippings are returned to the lawn. The main components of mulching lawn mowers are the mulching mower deck, blade design, and air circulation. These help your self-propelled lawn mower process to mulch grass clippings and fertilize the ground to keep your lawn healthy.

How do Mulching Blades cut grass?

Mulching blades use circulating air to cut suspended pieces of a grass blade into tiny particles. Here is the whole mechanical process outlined step by step:

  1. The lawn mower starts up, with the blades rotating between 2,800 to 3,100 RPM to create a circular air stream.
  2. A sharp lawn mower blade cuts the grass.
  3. Instead of bagging the cut grass, it remains suspended in the circulating air stream.
  4. The mower's blades continually chop the suspended grass into finely diced pieces.
  5. After several passes, the pieces become too small to remain airborne and fall back onto the lawn.
  6. The deck edge or crosspiece smoothens the fine mulch into the remaining grass.

There are several factors to remember when using a mulching lawn mower to cut your lawn. Ideally, your grass should never be taller than around 3 inches, and you should aim to mow every three to four days. Never mulch your lawn in wet or damp conditions, as this can lead to diseases.

What are the Benefits of Mulching?

What are the Benefits of Mulching

Advantages of Mulching

Mulching provides numerous benefits for your garden, including benefits for your soil health, plant growth, and overall environmental impact. Read our extensive outline on the benefits of mulching your grass and more.

Benefits Description
Soil Health Mulching enhances soil conditions for a healthy, lush lawn by reducing water loss, moderating temperature, maintaining optimal pH, and gradually releasing nutrients to support continuous growth.
Plant Growth Mulching improves lawn health and appearance by supporting beneficial insects for natural pest control.
Environmental Impact Your mulching lawn mower can reduce water runoff by up to 83%, enhancing rainfall absorption and ultimately lowering both your environmental impact and water bill.
Practical Mulching enriches your lawn’s appearance by keeping it lush, restoring dead patches, suppressing weeds, and saving time otherwise spent on clean-up.

Soil Health Benefits

Soil is integral for sustaining a lawn that's healthy and lush. Mulching plays a large part in creating the ideal soil conditions to help your grass keep looking its best, with exceptional help towards moisture management, temperature regulation, and nutrient enhancement. The presence of mulch helps reduce evaporation by up to 70% compared to unmulched soil, which helps retain water and keeps your lawn cooler in summer, according to Food Science and Nutrition.

The presence of mulch also helps with maintaining a healthy pH level throughout your soil according to Climate-Smart Agronomy, as blades decrease the acidity when they slowly release nutrients into the soil.

Plant Growth Benefits

These nutrients will also help the grass by acting as fertilizer or compost, encouraging the roots back into the soil to form stronger systems. Oklahoma State University has also noted that dedicated mulching also creates habitats for insects that benefit your garden. These insects control pests and other nuisances but would find it difficult to live if mulched clippings weren't regularly used to maintain your lawn.

Environmental Impact Benefits

In today's climate, actions that provide more excellent environmental benefits are incredibly important. The mulching capabilities of your lawn mower, whether a push mower or a riding mower, can help you precisely. Soil conservation and water conservation improve when you use cut grass clippings as mulch for your lawn. We've mentioned the benefits of soil conservation, but you can also conserve water.

Mulching decreases water runoff by between 28% and 83% and improves rainfall penetration, paying you less for your water ball at the end of the month.

Practical Benefits

Your lawn receives fantastic benefits when you mulch, but one of the most evident is how lush your backyard looks. Mulching can keep your grass looking green, fresh, and alive and revitalize the dead patches that have grown because of the summer's heat. Weeds are also suppressed when you avoid the mulching and bagging routine that takes hours of cleaning, so think of it as a win/win.

What are Some Common Mulching Myths?

Common Mulching Myths Debunked

These are the Common Mulching Myths Debunked

Mulching has several myths and misconceptions surrounding it, especially around lawn health and lawn pests. We've brought together a few of the most common mulching conceptions we've found and answered whether they're fact or fiction.

Conception Fact or Fiction?
All Mulch Is Equal The reality is that mulch comes in various types with unique characteristics and purposes. Different mulches serve different functions—organic mulch enriches the soil as it decomposes, while inorganic mulch offers longevity but provides fewer nutrients.
More Mulch Is Better Excessive mulching can be harmful. The ideal depth is 2–4 inches, as too much mulch can lead to blocked water, air, and nutrients.
Mulch is Maintenance Free Mulch requires regular attention, including periodic fluffing when the mulch is compacted, replenishment after decomposition, and evenly distributing mulch.
Mulch Attracts Termites Termites are not attracted explicitly to mulch. They may feed on it only if they are already in the area.
Grass Clippings Cause Thatch Returning grass clippings to the lawn only increases thatching tendency by about 3%, primarily due to added nutrients rather than clippings.

What's not a myth is the stellar performance of the Mowrator S1 Remote Control Lawn Mower, which comes with a 3-in-1 system that makes mulching, rear bagging, and discharge as simple as possible.

FAQs on What is a Mulching Lawn Mower?

Is a mulching mower better than a traditional mower?

A mulching mower is better than a traditional mower because it reduces the time required to clean your garden after mowing, but it also has limitations. While using an electrical lawn mower to mulch your grass can lead to a healthier lawn, they struggle in wet conditions and must mow often.

What time of year should I use a mulching mower?

The best time of year to use your mulching lawn mower is in spring and summer, preferably just after the first spring-cleaning mows. These active seasons help maintain your lawn's look and give you the best chance to impact the growth for the rest of the season. Always choose to cut your grass while it's dry.
