1. Top Choice – Hayter Harrier 48
Brand: Hayter Harrier
Cutting Width: 48cm

If you have a large garden that takes hours to mow then consider this Hayter Harrier to give you a helping hand. With a 48cm cutting width, this mower can manoeuvre smaller lawns whilst still coping extremely well with large lawns. It has a powerful 163cc Briggs & Stratton engine so works well in all conditions.
It has a 70-litre grass box which hardly ever needs emptying. It’s not only the grass collection that causes this mower to leave such a professional finish. The rear roller means you achieve a perfect striped lawn with ease.
The cutting deck is made out of corrosion-resistant aluminium, it is easy to clean due to a hose attachment and it automatically adjusts itself for optimum airflow. This allows it to effectively cut long grass and no grass clippings escape the collection bag.
It has an electric start so no struggling with a pull cord. It’s auto-drive and has variable speed settings so anyone can use it.
I could talk about this lawnmower all day, the features it has are too many to list! The only downside is it is quite pricey so may be too much if you have a tight budget. You get back way more than you pay for and it comes with a lifetime crankshaft and cutter deck warranty so you won’t need to worry about accidentally hitting a solid object when mowing.
2. Runner Up – Bosch Rotak Advanced 650 Corded Electric Mower
Cutting Width: 40cm
Power: 1700 watts
Grass Collector Size: 50L
Cutting Height Options: 25-80mm
- No need for pricey fuel
- Good cutting width
- Will likely require an extension cable
- Doesn’t feel as sturdy
I had to include a great budget option for those who hate petrol lawnmowers. This Bosch Rotak push mower is technically better for medium lawns but can also cope with larger gardens too up to about 650m2.
It’s extremely lightweight at only 16kg and the ergonomic handle has a height adjustment option which makes this mower very pleasant to use.
It will give you a clean finish due to grass combs that direct the grass towards the blade ensuring a close to edge cut even without using a trimmer. It is also fitted with a rear roller for a beautifully striped lawn. The cutting height has 7 height options between 25 and 80mm so you’ll get a perfect cut all year round.
With a decent-sized cutting width and collection box, this mower should cope with large lawns but the cord length is only 10 meters. You will need an extension cable to cover larger areas with this option.
This is a great budget option and perfect for anyone who struggles with heavy lawnmowers.
3. Best Robot Lawnmower Option – Husqvarna Automower 450X

Cutting Height Options: 20-60mm
- Covers up to 5000sq meters
- Including uneven lawns
- GPS tracks your garden
- 260 minute run time
- Very pricey
- Sometimes sold out
This lawnmower review list wouldn’t be complete without a robot lawnmower! For those of us who hate mowing the lawn, this is the perfect solution. It can mow an area up to 5000 sq meters and can cope with slopes up to 45% gradient.
It can mow for 260 minutes before it needs to re-charge and this takes 75 minutes. It does need an accessible charging station installed as well as a boundary wire. This is time-consuming but is a one-off task as once it’s complete the mower will do all the hard work for you!
With a smart GPS navigation, it knows which areas still need to be mowed and it even comes with a smartphone app so you can monitor it. It’s weatherproof and has a rain sensor so you don’t need to worry about it in the rain.
It has tilt and lift sensors so the blades stop turning if it’s lifted up which prevents injury.
It is expensive but it handles large gardens and complex terrain with ease and it’s self mulching so no clean up is required. It’s a great option if you’re fed up with tending to the lawn.
4. Best Petrol Lawnmower – Mountfield SP53 Elite
Cutting Width: 51cm
Power: 167cc Petrol Engine
Grass Collector Size: 60L
Cutting Height Options: 27-90mm
- Very wide cutting area
- Lots of cutting heights
- Honda engine
- Large back wheels ofr stability
- No rear roller for lines
- Lowest cutting height not as low as some people like
If you’re looking for a high-quality petrol lawnmower that comes with a low price tag then this Mountfield Elite is worth consideration. It comes with a Honda 167cc engine so you get all the cutting power for much less money. The engine has an auto-choke feature which makes for an easy start in all conditions.
It’s a really good sized mower with a 51cm blade and 60-litre grass collector. It also comes with a mulching plug option to help keep the lawn healthy.
It’s pretty heavy at 35kg but thankfully this mower is self-propelled so you won’t struggle to get push it uphill. Although it’s pretty bulky the foldable handles mean storage isn’t an issue.
The rear wheels are larger compared to the front ones. This helps give this mower stability and prevents it from marking up your lawn. If you let go of the handles the mower cuts out immediately which is a good safety feature.
This mower doesn’t come with a rear roller so won’t give a perfect striped lawn but you can always buy these separately if you like.
5. Best Electric Lawnmower – Einhell GE-CM 43 Cordless Mower
Cutting Width: 43cm
Power: 36V Of Lithium Batteries
Grass Collector Size: 63L
Cutting Height Options: 6 Levels
- LED lights indicate charge
- Cordless for further reaching
- Cuts 600sqm per charge
- Doesn’t do well with wet grass
- Works a little better for medium lawns
- Need to remember to charge batteries
If petrol isn’t your thing then a mower powered by lithium-ion batteries is a great option. These mowers are better for small gardens but can be used in larger areas as well. This is a cordless lawnmower of great build quality and one of the best cordless lawnmowers on the market.
It has a good-sized cutting width of 43cm and a spacious grass collector at 63L. This cordless model comes with two 4Ah batteries which should give you 600 sq meters of mowing per battery charge. It takes 80 minutes to re-charge the batteries so you can take a break for lunch and then finish mowing your larger lawn.
This mower is lightweight at 16.5kg and the large wheels are soft on your lawn. The batteries have 3 LED lights that indicate charge level so you know when it’s time to plug them in.
The downside with these types of lawnmowers is that they don’t have a very long runtime. If the lawn is very thick, long, or wets the batteries run out sooner. That can be frustrating if you have a large lawn area to cover, they’re better for medium gardens. Electric mowers are only good if really can’t manage a heavy mower or you hate the petrol fumes and general mower upkeep.
Large Lawnmower Buying Guide
Size Of Lawn
The area of your lawn is the first thing you need to consider when choosing a new lawnmower. Large gardens need a mower with an adequate cutting width otherwise it can take hours to mow the lawn. Unless it’s a Robot Lawnmower, for medium gardens you need a cutting width of at least 40cm and larger gardens need a cutting width of 50cm+.
Petrol Vs Electric
Electric mowers come in 3 different types. There are corded electric, cordless battery, and robotic lawnmowers. They all have their plusses and minuses. For a quick summary, we will leave out robotic mowers as they do the job for you! Corded mowers are lightweight and very easy to use but not very powerful and you are always limited by the length of the cord.
Battery mowers give you more freedom to roam and are still pretty lightweight and easy to use. The issue is that the batteries don’t tend to last very long, with about 30 minutes being the best they can manage. They are a good option for smaller lawns or if you struggle to manage a petrol mower.
Petrol mowers are heavy, emit fumes, and can be very loud. They require a lot of upkeep and some people struggle to start them. When it comes to larger gardens though, they perform well. They’re powerful and the self-drive can speed up the task at hand.
It’s worth weighing up your needs and the size and layout of your lawn to ensure you choose the model that’s right for you.
The power of the lawnmower tells you how well it functions on thick, long grass and uneven ground. A less powerful machine will struggle to cope in these conditions and damp grass can make them stall. If you have a complex lawn with slopes, thick grass, and rough patches then you’ll need a more powerful lawnmower. Power is often measured in cc for petrol engines and wattage or volts for electric models.
A self-propelled lawnmower not only saves time but also saves a lot of effort when it comes to cutting the grass, especially if you have a sloping lawn. Petrol lawnmowers are very heavy and produce a lot of sweat and tears if manually pushed over a large area. Unless you are looking for an army Bootcamp style workout every week then I’d recommend getting a mower with self-drive to mow a large lawn.
To preserve the life of your lawnmower it needs to be cleaned after every use. This can be done by hosing it down or using a sponge and bucket of water. Make sure you empty the fuel tank before winter storage and get your lawnmower serviced at least once a year or more if it is very heavily used. A lot of manufacturers will not uphold the warranty if the mower isn’t serviced so make sure you check over the manual before you set out to use your new mower.
How you ultimately want your lawn to end up is decided when you choose your mower. If you want a perfect striped finish you need a mower with a grass collector and rear roller. If you want a thick and healthy lawn then a mower with a mulching option is great. If you hate emptying the grass collector but don’t mind raking the lawn then a side or rear discharge option works well.
Which lawn mower is best for uneven garden?
A rotary mower with self-drive will navigate uneven ground better than a rear roller can manage.
What is the widest lawn mower?
At 56cm (22 inches) the Einhell GC-PM 56 S HW is the lawnmower with the largest cutting width on our list.
What is the easiest lawn mower to use?
A corded electric mower is simple to use. Plug it in, press the button, and off you go! Battery and robotic lawnmowers are also very user friendly and petrol mowers are defiantly the most tricky to use.
Which lawn mower engine is better Briggs & Stratton or Honda?
Honda is widely regarded as one of the best manufacturers of lawnmower engines. Briggs and Stratton engines are cheaper than Honda but still very well made. If well maintained they can last almost as long as a Honda engine.
What size lawn mower do I need per acre of lawn?
A half-acre lawn is fine to use a mower with a deck of 40cm or less. 0.5 – 2 acres will need a deck between 40-50cm and 3 acres or larger needs 50cm+.

Cutting Height Options: 25-75mm

Cutting Width: 46cm
Power: 120cc Petrol Engine
Grass Collector Size: 50L
Cutting Height Options: 30-80mm
Here’s another great option for medium to large gardens up to 1100m2. This Mcculloch petrol mower isn’t as big and powerful as some of the other ones on this list but the price makes up for this! For a petrol mower, 29kg isn’t too heavy and the self-drive means it’s easy to use on slopes as well.
The robust steel body will cope well with anything you throw at it and 5 different cutting heights make a clean and tidy finish. The collection bag is a lightweight fabric so easy to carry and this folds away as do the handles to make for space-saving storage.
As steel is prone to corrosion this lawnmower does need to be well cleaned after each use but it doesn’t have a hose connection so may need you to tip it to do so. It’s also a recoil start so prone to issues here if you find that you often struggle with these.
Cutting Width: 46cm
Power: 148cc Petrol Engine
Grass Collector Size: 60L
Cutting Height Options: 25-75mm

You can set the mower to cut and collect in the grass bag, side discharge or mulch to help nourish the lawn.
The engine is designed to dull down vibrations so this mower isn’t as loud as some other petrol options. It also has a comfortable, soft-grip handle which makes mowing the lawn a lot more pleasant. This handle also folds down to allow space-saving storage.
It has ergonomically designed, sturdy wheels that won’t mark up your lawn and make it perfect to navigate uneven lawns. It has a sturdy, steel deck and is an extremely hard wearing and reliable lawnmower, perfect for larger lawns.
The only downside with the Honda Izy is that the deck can end up suffering from corrosion. This doesn’t kick in until about 8-10 years of use and can be avoided if the lawnmower is washed and stored correctly.
