One Sunday morning you wake up, prepare some coffee, and look through the front yard window. The grass has grown so much that you can’t stand looking at it.

It’s time to mow your lawn. 

At A Glance: Our Top 5 Picks for Mulching Lawn Mowers

You set up the mower, turn it on, and start cutting. A few minutes pass, and you’ve mowed half the lawn. You check the bag, and it’s filled with clippings. It can’t handle any more than that. 

What do you do? The obvious action would be to find a plastic bag and empty the grass catcher. But what if you could reuse those clippings instead of dumping them away? 

That’s where a mulching lawn mower enters into play. Without getting rid of those clippings or even storing them, you can cut the lawn as perfectly as you want. The catch? You’ll leave the residues behind. 

This will give your lawn some food for later. As the clippings start to decompose, the soil will suck them up and gain many nutrients. The benefit? Your new grass will grow a lot greener and more beautiful.

How to Choose a Mulching Lawn Mower

While they may seem simple, you probably don’t know their intricacies. If you want to pick the right one for your mulching and mowing needs, then you better learn the details. Here, we explain what factors matter before making your final choice:

Types of Mower 

These mowers all look similar, but they are powered up differently. The difference of power and way of working could make it or break it for you. 

Gas

As the name says, these mowers are powered by gasoline. The motor power is measured in cubic centimeters (cc) and horsepower (HP). Gas mowers are heavy, but they can go anywhere and work for several hours non-stop, as long as there’s enough gasoline. Sadly, they require a lot of upkeep. 

Electric Corded

A power cord connects to an outlet, and the machine starts. The motor is measured in AMPs. Electric mowers with a cord stand out for their lightness. You can maneuver them with ease, as long as the cable allows it. As a downside, you won’t be able to use it in places with no outlets close.

Electric Cordless

For those who want the versatility of a gas-powered mower but the lightness of a corded one, nothing beats a cordless machine. Their power is measured in volts (V). And the only negative would be that batteries run out of power quickly, so they may not offer too long an operation. 

Power & Capacity

Given how the mulching lawn mower is powered, you should decide how much of that potency you’ll want.

For a decent measurement in gas mowers, we recommend no less than 100cc and 2 HP. That would be the minimum. If you want high-end results, go for at least 200cc and 5 HP.

If we’re talking corded mowers, a good measure would be anywhere from 10 to 15 AMPs. In case you’re looking for power, pick nothing less than 20 AMPs.

As for cordless, you’ll want nothing south of 20V. But if you care about power in cordless models, at least 50V should suffice to cut any yard with ease. 

Deck Size & Adjustments 

The mower deck is where the blade is located. For that reason, the size will tell you how long the blade will be and how wide of a cut it can make. The bigger the mower deck, the more grass the mower will get rid of.

Here, we recommend decks of at least 17 inches for a decent experience. Decks that are smaller than those are often not good at mulching, leaving thick clippings behind that don’t decompose well.

For an extra feature, pick a mower with an adjustable-height deck. It should have at least two heights to use. For the best experience, go for 7-position decks instead.

Mobility & Storage 

Lastly, consider those mowers that are easy to move around and require not much effort to store. This includes mowers with wheels larger than 7 inches and those with foldable handles. 

If you want a mower that stores with ease, check for special features like vertical storage or a hanging handlebar. 

Mulching Lawn Mower vs Regular Mower

You must be asking yourself, “why would I choose a mulching mower when a regular one could get the job done?” Well, here are a few reasons to consider:

  • Mulching mowers produce thinner and faster-to-decompose clippings
  • The clippings increase the moisture and reduce temperatures on the grass
  • This mulch increases nitrogen and other nutrients exponentially
  • Using a mulching mower reduces your waste by reutilizing the residues
  • Mulching lawn mowers save you a lot of time from the bagging and thrashing
  • They may also save you some money by reducing waste fees from landfills 

There’s simply no reason to dismiss a mulching mower. And what’s even better, they cost the same or even less than regular ones. 

Frequently Asked Questions (FAQs)

We explained a lot about mulching lawn mowers and went through some of the best out there. But we still left a few doubts in your head. Here, we intend to answer the most common ones:

What is mulching lawn mower?

Mulching often refers to the act of raking away the residues after mowing. In other cases, it refers to the pieces of bark from trees and wood residues. But in this case, a mulching lawn mower refers to something different. It is the clippings that mowers leave behind for the yard to benefit.

That’s why they’re called that way. As the mower cuts the grass, the clippings stay on the soil, producing fine mulch that eventually decomposes. 

How do mulching mowers work?

A regular mower has a thick blade that cuts grass once, leaving behind large clippings that look awful and don’t decompose too fast. In contrast, mulching mowers have more delicate blades, specifically designed to cut the grass up to thrice, delivering super-fine clippings instead.

Do mulching mower promote thatch?

No, the clippings from mulching mowers are fine and spread better, preventing thatch. Apart from that, clippings from the top of the grass rarely produces thatch. It is the roots and the stems that do. And mulching mowers don’t cut those.  

Conclusion

As you can see, a mulching lawn mower is not much of a mystery. Similar to regular ones, these mowers are actually better in many ways. And they can become your favorite gardening tool over time.

If you want to enjoy everything they offer, getting a quality model like those above would be a great idea. Don’t hesitate and pick the ones that best meet your demands. You won’t regret it!
