Whether you’re mulching, composting or eliminating thatch build-up, by the time you’ve read this post you’ll know everything you need to know about gathering up all the cut grass your lawn can deliver.
Bagging is counterintuitive. You might think that with their extra horsepower and big cutting decks, the best tool for bagging would be a zero-turn or ride-on mower, but you’d be wrong.
Zero-turns and ride-ons are not as manoeuvrable, they don’t fit in tight spaces, their grass bags don’t fit snugly, and, because they don’t have the suction power of push and self-propelled mowers, they leave behind clumps of grass and leaf debris.
The faster the blade spins, the cleaner the cut. With that in mind, I’ve compiled a list of highly-rated mowers with powerful motors. Later we’ll discuss what you can do to easily customise them and create the kind of bagging behemoth that consumes and devours everything in its path.

Bosch AdvancedRotak 750 Electric Rotary Lawn Mower
Key Features:
- Power Source: Mains electricity
- Power Capacity: 1700W
- Grass Capacity: 50-litre box
- Cutting Width: 44cm
- RPM: 4800
- Weight: 16kg
1700 watts is like having a cyclone on a leash. The Bosch mower’s cutting blade spins at 4800 revolutions per minute. That’s 80 times a second. Plus, it has a 50-litre capacity grass box, very nearly the largest there is.
The power cord supplied is good for small and, up to a point, medium-sized lawns. If you want to go bigger, you’re going to need an extension. Just make sure it’s rated for large household appliances like ovens and washing machines.
Pros:
- A height-adjustable guide bar
- 7 cutting heights
- Proprietary ProSilence technology reduces engine noise by 75%
- A proprietary LeafCollect cutting blade traps and shreds big leaves
- Light enough to hang on the wall
Cons:
- No grab handle at the point of balance makes it hard to carry
- A long, properly-rated extension cord is not included
Hyundai HYM3800E Corded Electric Rotary Lawn Mower
Key Features:
- Power Source: Mains electricity
- Power Capacity: 1600W / 230V
- Grass Capacity: 40-litre box
- Cutting Width: 38cm
- RPM: 3700
- Weight: 13.8kg
This mower combines utility with styling features. A rear roller and low-cut settings produce that striped look so beloved by English homeowners while a grass comb trims the lawn all the way up to the edges of paths, walkways and garden walls.
Half the weight of a petrol mower, this Hyundai still reaches a respectable 3700 RPM, so you can bag all the cuttings you need while applying the finishing touches to your lawn.
Pros:
- 5 cutting heights
- Rear roller
- Mulching option
- No oil, air filters or spark plugs to deal with
- A quick-release mechanism that empties the grass box without spillage
Cons:
- The grass box could be bigger
- Not suited to large lawns
Greenworks GD40LM46SP 46cm Self-Propelled Cordless Lawnmower
Key Features:
- Power Source: Greenworks 40V battery, sold separately
- Self-propelled: Yes
- Grass Capacity: 55L bag
- Cutting Width: 46cm
- Cutting heights: 7, from 25mm to 80mm
The Greenworks GD40LM46SP replaces the Greenworks kit that was on this list. The Greenworks GD40LM46SP collects into a 55L bag, one of the largest on any cordless mower. The 46cm deck and self-propelled drive make it quick work on medium to large lawns.
You can also switch to mulching or side discharge. This listing is the bare tool, so budget for a Greenworks 40V battery and charger if you do not already own one. A 4Ah battery covers up to 600m².
Pros:
- Big 55L bag
- Self-propelled
- Also mulches and side discharges
- 3 year guarantee
Cons:
- Battery and charger cost extra
Hyundai 46cm Self-Propelled Petrol Lawnmower
Key Features:
- Power Source: 139cc 4-stroke petrol engine with auto choke
- Self-propelled: Yes
- Grass Capacity: 60L box
- Cutting Width: 46cm
- Cutting modes: Collect, mulch, side and rear discharge
The Hyundai 46cm self-propelled petrol mower has the largest grass box on this list at 60L. The Hyundai 46cm replaces the Hyundai model that is no longer available. The Hyundai 46cm is the petrol pick for anyone who collects every cut.
A petrol engine keeps strong suction through long or damp grass, which helps the bag fill evenly. The rear-wheel drive pulls the mower along, and the auto choke makes starting simple.
Pros:
- Huge 60L grass box
- Self-propelled
- Strong suction through long grass
- Auto choke
Cons:
- Petrol engines need servicing
- Louder than electric mowers
Bosch Rotak 34R Electric Lawn Mower
Key Features:
- Power Source: Mains electricity
- Power Capacity: 1300W Powerdrive
- Grass Capacity: 40 litres
- Cutting Width: 34cm
- RPM: 4800
- Weight: 11.1kg
This mower doesn’t have the broadest cutting width and the grass box could be bigger but it more than makes up for these deficits in other ways.
At just over 11kg, the Rotak 34R is the lightest mower in its class. It has a carry handle at the point of balance so getting it out and putting it away again is a breeze.
Despite its small, compact size, the Powerdrive motor delivers a very respectable 1300W and 4800 RPM, equivalent to the best of its high-power counterparts.
Pros:
- At 11.1kg, it’s exceptionally lightweight and manoeuvrable
- A powerful motor with high RPMs
- Compact for easy storage
- A rear roller for the striped finish
- Inset front heels and grass combs for precision edge-trimming
Cons:
- A comparatively narrow cutting width
- The height of the guide bar can be fidgety and frustrating to adjust
Makita DLM462Z 36V Cordless Self-propelled Lawn Mower
Key Features:
- Power Source: Electricity
- Power Capacity: 36V
- Grass Capacity: 60-litre box
- Cutting Width: 46cm
- RPM: 3600
- Weight: 39kg
It’s as if the engineers at Makita were told to go forth and create a cordless lawn mower in every way equal to its petrol counterpart. What they came up with is the Tyson Fury of bagging mowers: a self-propelled garden tool with four battery ports, a brushless motor, a steel deck, a massive 46cm cutting width and a 60-litre grass box.
This mower changes from self-propelled to a walk-behind with the flick of a switch. You also have the option of maintaining a constant cutting speed or engaging the automatic throttle, in which case the engine slows down when there’s nothing to cut.
At the same time, it enjoys all the benefits of battery technology: no exhaust fumes, quiet operation, low maintenance and none of the drawbacks of a petrol engine.
Pros:
- 4 battery ports
- A brushless motor
- 10 cutting heights
- A steel deck
- Variable speed control
Cons:
- Getting its 36kg in and out of storage might be a problem if you have a bad back
- Batteries are not included
Swift 40V 32cm Brushless Cordless Lawnmower
Key Features:
- Power Source: 40V 2Ah battery, charger included
- Grass Capacity: 30L box
- Cutting Width: 32cm
- Weight: 12.7kg
- Coverage: up to 200m²
The Swift 40V replaces the Murray cordless mower, which is no longer sold. The Swift 40V is a light, budget cordless kit for small lawns. The Swift 40V collects into a 30L box, or you can switch to mulching.
A brushless motor is unusual at this price. The battery and charger come in the box, so there is nothing else to buy. With over 1,200 Amazon ratings, the Swift 40V is one of the most reviewed budget cordless mowers in the UK.
Pros:
- Battery and charger included
- Brushless motor
- Light at 12.7kg
Cons:
- Small 30L box
- Suits small lawns only
Flymo EasiGlide 300 Hover Collect Lawnmower
Key Features:
- Power Source: Corded electric, 10m cable
- Power: 1900W
- Grass Capacity: 20L box
- Cutting Width: 30cm
- Cutting heights: 4, from 10mm to 30mm
The Flymo EasiGlide 300 replaces the EasiGlide 300V Plus, which is no longer on Amazon UK. The Flymo EasiGlide 300 is a hover mower that also collects. Most hover mowers leave clippings on the lawn, but the EasiGlide 300 collects and compacts them into a 20L box as it cuts.
Floating on air makes it easy to mow slopes and awkward shapes. The handles fold flat so it can hang on a wall. With over 4,700 Amazon ratings, the Flymo EasiGlide 300 is one of the best reviewed hover mowers in the UK.
Pros:
- A hover mower that collects
- Light and easy on slopes
- Folds flat to hang up
- Very well reviewed
Cons:
- Small 20L box
- Narrow 30cm cut
How to Buy the Best Mower for Bagging
Mowers with the highest RPM score on two fronts: they provide the cleanest cut and the cut grass is finer, doubling the capacity of your grass bag. Finer cuts also decay more quickly and more easily, making better fertiliser.
There are four different types of mower blades on the market: straight, dual, mulching and high-lift. There’s no reason why you shouldn’t own one of each and swap them out yourself.
Straight is the ‘common-or-garden’ variety, while the dual-blade system is better at long, thick grass. The mulching blade sprays grass in every direction – pretty much the opposite of bagging – while the high-lift blade creates a vortex that sucks everything up into the bag, which is exactly what we’re looking for.
To create your bagging hybrid, choose a mower with a high RPM, fit it with a high-lift blade and then finish it off with a 60-litre grass bag.
If you decide on a cordless mower, consider investing in an extra charger and a couple of high-capacity batteries. They’re not cheap but they’re small and compact and they take two seconds to swap out. That way you’ll never have to worry about running out of juice before the job’s done, no matter how big an area you have to cover.
Frequently Asked Questions
Which is better at bagging, a ride-on mower or a push mower?
Ride-on mowers are better at almost everything else but push mowers are better at bagging.
Is there one blade that’s good at everything?
The straight blade is considered general-purpose but can struggle with long, thick grass that a dual-blade would have no problem with. Specialist blades like the mulching blade and the high-lift are not general-purpose.
Conclusion
Bagging and composting should be high on the list of every gardener’s priorities. While grass cuttings are not the best fertiliser for a lawn that has been neglected and run to seed, they’re perfect for maintaining a lawn that’s already pristine. They’re completely natural, eco-friendly and cost next to nothing. It’s recycling in its purest form and all it takes is a little effort.
Please remember to always check your lawn for hedgehogs and other wildlife before you start mowing. Small creatures are essential to a healthy ecology. For more information, visit Hedgehog Aware.
