If your lawn measures up to 1800 square meters, then this mulching mower may be a reliable option for you, as it is built for those kinds of workloads. It has a powerful engine from Briggs and Stratton that facilitates an easy start capability, so you don't need to go through any kind of warmup process before you start mowing. Additionally, there are low emissions, and there is also low operational noise.

Along with the traditional cutting function, you also get side discharging and a sweet mulching capability. I'm always looking to improve my soil quality, and if you are too, a good mulching mower is always an asset.

Greenworks Tools Cordless Lawn Mower G40LM35K2

Best Value

This mulcher lawn mower from Greenworks stands out because of its feature combination. Much of what it can do is the kind of stuff that you expect to see from mulching lawn mowers on the less affordable side of the spectrum.

I think this is an excellent option for people who have lawns of 500 square meters or less to mow. Based on the battery capacity and the 35-centimeter cutting with, this unit is better suited to gardens of such sizes.

There are five height intervals between 20 and 70 millimeters for cutting, which is excellent since it allows you to trim things down super close to the ground or a little higher if you so desire.

Not only is there a grass collection bag to help deal with grass clippings, but there is also a super sweet mulching function. This fosters better soil, which leads to the kind of healthy lawn that I mentioned earlier.

Greenworks Tools Cordless Lawn Mower GD40LM46SP

Most Customizable

I simply cannot get over the speed adjustment functionality that this mower brings. One of the problems I've had with mulching mowers that aren't self propelled is that most of them tend to feel a bit off based on my natural walking speed. I find myself having to walk too slowly, or I end up feeling like I'm running a sprint. Thankfully, this one from Greenworks has a well-built speed adjustment function, which means that the mowing speed is determined by your comfort pace.

Alongside the regular mowing functionality, there is a side discharge mode and a mulching function that feeds your lawn with all the goodies that it needs to stay healthy.

When you buy a lawn mower, you probably prepare yourself for the level of noise that you must deal with while you use it. Unfortunately, your neighbors must deal with it too. However, this mower is surprisingly quiet when compared to some others.

Cutting width and height are also important. This unit has a 46-centimeter cutting width, and it has seven height presets that you can use to determine how low you want your lawn. If your grass-covered space measures anywhere up to 750 square meters, then this should be a reliable option.

  • Side discharge mode present for grass clippings

Best Budget

This corded electric option is designed for lawns up to 144 square meters. It has a relatively small grass box, which should be fine based on the kind of workload that the mower is built for. Though it's corded, the cable is 10 meters long, and there is built-in cable support to prevent some potentially serious damage.

I'm one of those people who loves the aesthetic of a mowed lawn with stripes, so you can bet that I was pleasantly surprised to see that this Hyundai mower is designed with a rear roller to help achieve this effect.

Not only does it function in a smooth manner, but it is designed with ergonomics in mind, which is great for those who want to be as comfortable as possible while they complete their mowing duties.

I tend to worry about petrol powered mulching lawn mowers because of the cost associated with their fuel source. However, I find that the optimization of this unit is very well done, since it does not consume petrol at an alarming rate.

Good to Know Info For Mulching Lawn Mowers

What Is a Mulching Mower?

Mulching lawn mowers are equipped with special blades that produce a different result from your traditional cut. Instead of generating average-sized grass cuttings that require raking or blowing away, a mulching mower repeatedly and swiftly cuts grass clippings until they are so fine that they can disintegrate.

This allows them to be easily reintroduced into the soil to provide nutrients the same way fertilizer would. This also means that you don't need to worry about grass collection.

How to Choose the Best Mulching Lawn Mower

First, you need to understand that this is a very subjective question. If there were one standard, and there wouldn't be a need for so many mulching lawn mowers. What is important is that you choose a mulching mower that meets your financial, lawn size, cutting width, and feature requirements.

For example, if you have a small lawn and your biggest consideration is to save as much as possible, then the Hyundai HYM3300E 1200W 230V Corded Electric Rotary Lawnmower may be the best mulching unit choice for you, since it is the most affordable on this list.

Similarly, you may want a mower that has the side discharge functionality. In such a case, they Makita PLM5121N2 Mulching Lawnmower could be a solid choice, since it offers that feature.

Is Mulching Better Than Bagging?

It's hard to say that one of these is definitively better than the other one where mowing the lawn is concerned. After all, both allow you to get rid of that pesky overgrowth after you've run your lawn mower over the grass.

If that is your only objective, then the only difference would be that grass collection would require a bit more work on your part. However, if you consider the condition of your soil, then a mulching mower may be a better idea.

Unlike bagging, mulching allows you to nourish the earth in which your grass resides with small, nutrient-rich grass cuttings, which is likely to result in a progressively healthier lawn. This is a great reason to go for lawn mowers that mulch.

Gas Vs. Electric Power

Any mulching lawn mower that you purchase is likely to be powered by either gas or electricity. Note that electric-powered mowers come in corded and cordless variations. If your mower uses a battery that is charged by electricity, then it still counts as an electric mower.

Petrol mulching mowers tend to be more powerful than electric mulching mowers. However, they also produce way more emissions, and they tend to be on the noisier end of the spectrum.

On the flip side, electric mulching mowers have the freedom to be quieter and more eco-friendly than petrol alternatives. However, they're normally missing the kind of power that petrol mulching mowers have. This means that your lawn mowing exercises may take a bit longer with your electric-powered motor.

Choosing one or the other is simply a trade-off. Do you prefer to have more power accompanied by noise and potential emissions? Alternatively, do you prefer a cleaner and quieter, yet slower experience?

How Important Is Maintenance?

Maintenance is yet another consideration that you must make during any mulching mower purchase. By extension, you should think about and consider this as you purchase any piece of machinery. If you maintain the machine in an inadequate manner, then don't expect it to accompany you during your mowing exploits for as long as it possibly can.

However, the acceptability of your maintenance depends on the requirements of the unit. Some of them require much more than others. For example, a petrol mulching lawn mower is likely to require petrol and potential engine oil changes, while an electric-powered mower may not require much more than a plug in or a charge to care for its power source.

Try to choose a mulching lawn mower that is well within your maintenance capabilities.


As you can see, there is quite a bit for you to consider when choosing the best mulching lawn mower. Based on the combination of capabilities and the various considerations highlighted above, the Makita PLM5121N2 Mulching Lawn mower is my pick for the best mulching mower overall.

First, it has the best feature set combination, it can easily get through small lawns, is perfectly suited for medium-sized lawns, and could even be a potential consideration if you have a larger one.

Additionally, while it has other ways of dealing with grass cuttings, its mulching capability is the best present, and it is a gas-powered mower that manages to have low emissions while not being too loud. Additionally, it's not the hardest unit on the market to maintain.

It may not be as affordable as the others on the list, but the fact that it has the upper hand in so many other areas makes it the best mulching lawn mower choice in my book.
