Looking for the best mulching lawn mower? Mulching mowers are fast becoming the preferred way to look after your lawn, thanks to their amazing recycling abilities. Not only does a mulching lawn mower cut your grass, but it also replenishes the nutrients in the soil by recirculating your grass clippings back into the lawn.

This process saves you from having to use chemical fertilizers that are both bad for the environment and the wildlife in your garden. It also saves you the hassle of clearing up messy clippings or having dead grass rotting in unsightly clumps on your lawn.

In addition to these benefits, the design and technology of specialized mulching lawn mowers has advanced in leaps and bounds in recent years. So there are now many different models to choose from.

But don’t panic; we’ve done the research and put together a list of our top picks to help you select the best mulching lawn mower for your needs.

So let’s take a look!

This mower has all the key features of a good mulcher: adaptability, reliability, power, and convenience.

Buyer’s Guide to Choosing the Best Mulching Mower

Before you make your final choice, we have listed below a few key things to look out for when deciding which mulching lawn mower is best for you.

Gas, Electric, or Battery-powered?

These days, mulching mowers are available in both gas and electric models. Gas engines provide more power and allow you to cut thick, long grass without any issues. They also don’t require power cords and can be topped up easily.

However, gas engines are pretty noisy and less kind to the environment. They give off emissions that aren’t eco-friendly, and they are also generally more tricky to keep ticking over smoothly.

On the other hand, electric mulching mowers are kinder to the environment with no nasty emissions. They also tend to be quieter and are less likely to disturb your neighbors.

Battery-powered mowers are cordless and convenient. However, they require frequent recharging if you don’t want your mower to cut out mid-mulch.


Many mulching mowers have dual-use decks, with bagging and side discharge abilities, as well as the mulching function. Bagging is great for those times when you have friends or family over and you want your lawn to have a clean finish.

Note that it is important not to confuse side discharge with mulching, as they are not the same thing. While opening the side chute on your mower will spread the grass cuttings, it will not re-cut them into micro clippings or propel them back into the soil as a mulching mower will.

Additionally, side discharge can leave dead grass rotting on your lawn, which is not helpful to its health. However, mulching encourages the grass clippings back into the soil for a vastly different result. To learn more about the pros and cons of each of these, check out our article on mulching vs side discharge here.

Overall, multi-functional mowers are great and give you more options from one machine. But be sure that the multifunctionality does not disguise a lack of mulching ability.


A large cutting width is very handy to have on any mulching mower, as it allows you to cover more of your lawn with each pass. As a result, it speeds up the task of mulching and mowing and allows you more time to relax and enjoy your lawn.

However, size isn’t everything. A wide mower will be heavier and more tricky to store. And if you have a small garden, it may be a better option to choose a lightweight and easy to maneuver mower instead.


Always look to see if the mulching mower you pick is self-propelled or push-powered. A self-propelled mower will be ideal if you have back issues or large lawns to maintain.

However, push mowers give you much more control over the speed at which you walk up and down the lawn.

And if you are fit and healthy and don’t have too much ground to cover, they are a great, affordable option.

Frequently Asked Questions

How Does A Mulching Mower Work?

A mulching mower works like a regular lawn mower, slicing the blades of grass on your lawn to make them shorter.

However, rather than expelling the grass cuttings out of a side chute or sucking them into a bag, a mulching mower keeps the loose grass contained under the deck of the mower and re-cuts it multiple times until it becomes micro-clippings.

These tiny pieces of cut grass are then propelled downwards into the ground, where they reintegrate into the soil and give all their nutrients back to the earth.

What Are The Benefits Of Mulching?

Not only does mulching return nutrients back to the soil, encouraging healthy growth, but it also cuts down on the amount of garden waste you produce and saves you the hassle of collecting dead cuttings from your lawn.

When Should You Mulch?

Mulching works best on dry grass, as the blades can cut more effectively and don’t become clogged up with mushy cuttings. For this reason, it is best to water your lawn after you have used your mulching mower and never before.

Are There Any Downsides to Mulching?

While mulching the lawn has many benefits, there are also some downsides. These include increased mowing time, the potential to spread weeds, and an extra mess to deal with, especially if your grass is long or wet. For more information on the downsides, check out our article on the disadvantages of mulching grass.

Final Thoughts

If you care deeply about your lawn and want to improve its health and upkeep, then a mulching lawn mower is an excellent choice.

Not only will it help make your grass more lush and green due to the added nutrients it harnesses, but it will also save you time, energy, and trips to the green waste bin!
