5 Best Mulching Lawn Mowers of 2025

If you’re wanting to mulch your lawn clippings instead of collecting them, the LawnMaster 24V 34cm Cordless Lawnmower is the best option. This mulching lawn mower is cordless and weighs just 11.4 kg, so it’s easy for anyone to use and manage. It has a cutting width of 34 cm. 

This mower offers two ways to dispose of your grass clippings, either mulching the cut grass or collecting it in the 32 L grass bag. The grass bag isn’t enormous, so if you’ve got a larger garden, mulching the clippings is a better option.  The mulching feature works very well and is a great alternative to collecting the clippings. 

It’s very easy to assemble, with the entire process taking less than 10 minus. Simply slot in the handles, then secure them in place with the bolts. There’s two different handle height settings to choose from depending on your height. 

This mower is lightweight (11.4 kg) and compact, which makes it ideal for smaller gardens or those who may struggle with a heavier machine. Although it feels flimsy at first (being made predominantly from plastic), I actually found it to be very decent quality. There’s a bright orange rear roller underneath, which will produce stripes on the lawn. 

In terms of power, there’s two 4aH batteries included. You can have one charging while the other is in use, and the run time is around 30 minutes depending on the grass conditions. Mine lasted around 45 minutes, but this included stopping and starting a couple of times. There’s an indicator to let you know how much charge you’ve got left. 

One of the best things about this mower is the intelligent battery management system. This adjusts the power of the mower depending on the conditions, for instance preserving battery life by lowering the power when the grass is short and dry. 

I tested this mower in a range of conditions, and it performed surprisingly well on wet grass. It also did a very good job on longer grass, although extra power is required in thick patches. There’s 5 height settings to choose from, between 20 and 70 mm. 

Perhaps the only downside of this mower is that, due to the lighter weight, the stripes produced aren’t that clear. There’s not enough weight behind the mower to push that roller down, which I suppose is a good thing! 

All in all, I’d happily recommend this model as my top choice if you’re after a cordless mower that also mulches the grass clippings. The fact that it comes with two batteries and a fast charger make it much better value than others I’ve looked at.

If you’ve got an overgrown garden or the tendency to let your grass grow long, the Greenworks G40LM41 Cordless Lawnmower is a great option thanks to the maximum cutting height of 80 cm, longer than other cordless models on the market. 

The shortest cutting height is 25 mm, so you’ll still be able to get a neat and short cut if needed. It’s great for gardens up to 500 m² because clippings can either be collected in the 50 L grass bag or mulched, allowing you to keep mowing without interruption. The 41 cm cutting width ensures it’s efficient across open stretches of lawn. 

The main downside of this mower is that it doesn’t come with a battery or charger included. So, while it might appear to be a very good price, the battery and charger will add substantially more to the price tag. 

There’s 18 cm rear wheels that make it easy to move over various terrains, including bumpy and undulating ground. The handle also folds down for easy storage. 

It’s fairly heavy for a cordless model, at 18.5 kg. While it’s not quite the weight of a petrol machine, those who prefer a lightweight mower should opt for another model. This is also minus the weight of the battery, so the total weight will be even more. 

There’s 6 cutting heights to choose from, ranging from 25 mm to 80 mm. While the 80 mm setting is perfect for longer grass, you can still get a smart cut using the 25 mm setting.

Overall, this lawn mower does everything you’d expect from a mulching lawn mower, and has all the features you’d need. The 50 L grass box and mulching feature means you can mow for long periods without interruption. 

The Kärcher LMO 18-33 18 Volt Cordless Lawn Mower is another cordless model. At 11.6 kg, it’s lightweight, while the 33 cm cutting width means it’s easy to manoeuvre around smaller gardens. 

Design-wise, it stood up to the test. While made predominantly from plastic, it’s well shaped and rigid. One neat design feature is that the body of the mower is as wide as the wheelbase. This means that the blades cut almost as wide as the machine, making it much easier to get close to walls and fences. 

While enough juice to cut a reasonable size lawn, this mower does only have 18 V of power. It comes with a 5.0 Ah battery which offers 24 minutes of cutting time. This battery can be used across a range of Kärcher machines. 

It runs incredibly quietly, which was a pleasant surprise! At full speed, it’s no louder than a hair dryer, while the electronic brake means as soon as you let go of the trigger, the power cuts out. 

Features-wise, it’s fairly simple. There’s a carry handle on top that makes it easy to transport, while you’ve got 3 mowing height positions to choose from. The mulching plug works well and ensures you’ve got the option to either collect the clippings in the 35 L bag, or deposit them back onto the lawn in finely chopped pieces. 

Once up to full speed, this mower has the power for long grass, but it can’t cope if you start it up on long grass. It gets bogged down and stops when it feels overloaded. Overall however, it cuts neatly and straight across the blades of grass at all 3 of the heights. 

It also comes with a safety key, without which the mower cannot run. This is a great feature for those with children or pets, as you can leave the mower where it is and be certain it won’t run if you have removed the safety key. There’s also an electronic brake, so the mower stops dead if you let go of the trigger. 

All in all, I was very impressed by this mower, despite the few shortfalls. It’s simple, affordable and easy to use, and that counts for a lot when it comes to domestic mowers. 

Hyundai is a brand renowned for their powerful machines, and the Hyundai HYM3800E Corded Electric Rotary Lawnmower certainly met expectations. It’s a good size for medium size lawns, with a 38 cm cutting width, and it comes equipped with both a mulching feature and a rear roller. 

The 38 cm cutting width ensures it’s easy to fit this mower through narrow gates and passageways, but it’ll also cover ground fairly efficiently in medium size gardens. There’s 5 adjustable cutting heights, ranging from 20 – 70 mm, as well as a 40 L grass bag. 

It comes with a 1600 W motor that allows it to tackle long, overgrown grass as well as short. The roller leaves noticeable stripes on the lawn as well, while there’s a 10 m cable that offers you freedom to move around smaller lawns. 

A particularly neat point is that this mower can be stored vertically, saving on space in the shed. The handlebars also fold down over the mower’s body. 

Although heavier than some of the other models I’ve tested, at 12.5 kg, this mower is still easy to push and carry. Overall, it’s a powerful mower for medium size gardens, and the addition of the mulching plug means it’s very versatile. 

If you’re after a mulching lawn mower that should suit most budgets, I highly recommend the GardenTek Corded Electric Roller Mulching Lawn Mower. This budget-friendly mower is lightweight and easy to use. Unlike cordless mowers, the 10 m power cable ensures you’ll have a continuous run time and won’t be limited by a poor battery life. 

This lawn mower weighs just 9 kg. Which makes it ideal for those who value a lighter machine. There’s 3 cutting heights to choose from ranging from 20 mm to 60 mm, and a 30 L grass catcher. 

However, there’s also a mulching plug that cuts the grass trimmings finely enough to return them to the lawn. The result is a healthier, greener lawn. This also allows you to mow for longer without interruption. This, along with the power cable, means you could mow a larger lawn with this machine. 

There’s a rear roller which will produce those traditionally British stripes. This is a great feature for such a compact and affordable machine. The stripes produced are smart and visible, which was a welcome surprise! 

Power-wise, it can cope with most domestic lawns. It can struggle in very dense or long grass, so this may need to be tackled with a strimmer beforehand. However, I did find it produced a neat (and striped!) finish on a well-maintained lawn, which is all I could really ask for. 

Although it is lightweight, it’s worth mentioning that this mower isn’t self propelled. While this does allow you to move at your own pace, it doesn’t have that weightless feel that self propelled mowers do. 

Some users also reported that this mower was difficult to assemble, although I didn’t find this to be the case. 

All in all, this model is a great choice for smaller gardens as well as those who don’t want to be limited by a short battery life. The 10 m cable should be enough to get around most gardens, and the rear roller is a great extra feature.
