The UK's bestSelf Propelled Lawn Mowers2022 Review

We've reviewed the best Self Propelled Lawn Mowers on the UK market.

Here are the products we believe are worth your consideration…

What To Look For in a Self Propelled Lawn Mower

If you have a large garden, a self propelled petrol lawn mower will be most suitable. Petrol mowers save a lot of effort and help speed through the job. Anything over 170 cc will be a powerful machine, although engines upwards of 125 cc will still suit most medium and large gardens.

For small/medium outdoor spaces (up to 500 m²), you may prefer a cordless battery-powered model. These are lighter and easier to manoeuvre but can be limited by battery run time. At most, you can expect around 30-40 minutes.

For large gardens, choose a cutting width of 42 – 56 cm. For medium gardens, a cutting width of 30 – 40 cm is suitable. Stick to a narrower model if you’ve got a lot of obstacles or trees to navigate around! 

A grass collection box of at least 60 L is best for larger lawns and a 40 L grass box is suitable for smaller gardens. If you want to improve the health of your lawn, look for a mulching feature. This will chop the clippings and release them back onto the grass. 

You’ll also want a few variable cutting heights. Mowers with a minimum cutting height around 25 mm are perfect for UK lawns. A maximum cutting height of at least 50 mm is useful for cutting long, damp or damaged grass.

Depending on the layout of your garden, you may occasionally need to use your mower without the self-propelled motor. Electric mowers generally weigh less than 20 kg which makes them easier to push manually when necessary. Petrol mowers can weigh over 30 kg. This weight is manageable, but if you’ve got a long way between the storage area and lawn, you may prefer a lighter model.

After researching various self propelled mowers, I’ve gone with the Hyundai HYM510SP Self Propelled Petrol Lawn Mower as my top pick. This mower is great for large gardens, with a 51 cm cutting width, a 70 L grass bag and six cutting heights.

    Hyundai-HYM510SP-4-Stroke-Petrol-Lawn-Mower-manouverability

    If you’re looking for the best self-propelled lawn mower, the Hyundai HYM510SP Self Propelled Petrol Lawnmower should be top of your list. It’s one that we’ve tested and it scored incredibly highly. (Read the full review here).

    As a starter for 10, it has a 196 cc engine which means it can power through both short and long grass, including grass that is slightly damp. Then, although it’s quite heavy at 38.7 kg, the self-propelled motion sees it moving at a fast-but-comfortable walking pace – even over more difficult terrain.

    Plus, with a steel deck (instead of the commonly-found plastic deck) it feels strong and sturdy as it goes over bumps, without bouncing all over the place.

    There are a lot of features to mention, and this mower has a large 51 cm cutting width, five cutting heights (ranging from 25 – 75 mm), mulching capabilities and a large 70 L collection bag. It’s also possible to connect a hose to the deck to make it easier to clean.

    The cutting heights can be adjusted using just one lever, which alters the height of all of the wheels at the same time, making it simple to change between settings. It also has foldable handles to make it more compact and easier to store, and is easy to assemble with no tools required.

    It’s one of the best self-propelled mowers for larger lawns, and it copes very well with uneven terrain. There are only a couple of downsides worth mentioning.

    Firstly, the grass collector is a bag not a box, and doesn’t seem overly hardwearing; however, it does have a hard lid which offers reinforcement. Secondly, it’s quite a heavy lawnmower, and many people will likely struggle if they need to get it up steps or in and out of the car.

    For this reason, it’s better suited to large spaces where having this much power (and weight) is justified. For smaller gardens, there are cheaper, more manageable alternatives.

    But, overall, this is a powerful and capable mower with a lot of good features and very few flaws.

    Pros

    • Easy to start thanks to the electric starter
    • Powerful enough to cope with uneven, challenging terrain in gardens
    • Self-propelled pace is fast but comfortable
    • Can clean deck by connecting a hose directly to it
    • Mulching capacity as well as grass collecting option

    Cons

    • Heavy construction means it's difficult to lift up/down steps, out of cars, etc.
    • Predominantly fabric grass collector doesn't feel as sturdy as a solid box
    • Best suited for large gardens because size/price likely excessive for smaller spaces

    If you’re looking for a self propelled lawn mower from a respected British brand, the Webb WER410SP Self Propelled Mower is a popular choice among UK gardeners.

    This mower copes well on standard lawns and offers a good balance between quality and affordability,

    It has a 41 cm cutting width and there are seven cutting heights to choose from, ranging from 25 – 75 mm. As a result, it’s a great choice for medium-size gardens, and it’s still small enough to navigate into some tighter areas as well.

    In addition to this, customers report that the 28 kg weight is manageable enough to carry, therefore meaning that this mower can be picked up and transported to the moving location when necessary.

    It also has a solid steel cutting deck that copes well over bumpy, uneven ground.

    The self propulsion speed is relatively fast, but it can be controlled somewhat by only squeezing gently on the throttle. It’s also possible to use the mower without the propulsion on; the ball bearings in the wheels permit movement even when pushing manually. This is useful when working around obstacles or in smaller areas where you need to mow a little slower.

    The 45 L collection box fits snugly to the mower meaning there are very few leaks and clippings don’t escape when moving. The downside of this is that it can be a little difficult to remove the box, at which point some grass may spill out. There’s no mulching function, but this mower has the option of rear discharge or collecting the clippings.

    As a 4-stroke mower, there is a separate section for oil. This will require a funnel to fill it because it is in a slightly awkward position.

    Overall, this is one of the best self propelled lawn mowers in terms of value for money. It offers good quality and speed, at an affordable price for a 4-stroke mower. It’s a great choice for medium gardens due to its combination of size and power, but it would also be an appropriate choice for larger gardens too.

    Pros

    • Good for all sizes of lawns because it offers a good compromise between size and weight/manoeuvrability
    • Self propulsion can be deactivated to make it easier to get into smaller areas or around obstacles
    • Ball bearings helps wheels move easily even when the self propulsion isn’t on
    • Fast speed on self propulsion, which can also be reduced by releasing pressure on the throttle
    • Can be pulled backwards for transportation, although there is some resistance

    Cons

    • The wheels stick out which means that it is more like 44cm wide even thought the cutting width if 41cm
    • Due to the design of the collection box, you may spill some clippings as you disconnect it from the mower
    • A funnel is required to fill up the oil tank as it is in a position that is difficult to reach
    • Hot starts can be difficult and require several pulls, although cold starts are very reliable

    One of the best battery-powered self propelled mowers, the Hyundai 40V Lithium-ion Cordless Self Propelled Lawn Mower is perfect for medium size gardens. It runs quietly and is quick to charge.

    Sporting Hyundai’s signature blue-and-grey colour scheme, this battery-powered mower has a modern, streamlined design.

    The 42 cm cutting width is perfect for medium lawns and there are six adjustable cutting heights ranging from 25 – 75 mm. Most battery-powered mowers don’t offer such a range of heights, so the HYM40LI420P is one of the best self propelled mowers if you want an electric, cordless model, without missing out on high cutting features.

    It’s suitable for bumpy, uneven lawns and can tackle longer grass that hasn’t been mown for a while.

    This cordless mower has a 40 V lithium-ion 2.5Ah battery included. On paper, it’s advertised as having a run time of 15 minutes; however, customers have reported that it often lasts longer than this. For medium lawns, you shouldn’t need to stop and charge the battery partway through.

    The achievable cutting time also depends on the type of grass. For regular trims on standard lawn grass, the battery can last around 30 minutes. With long grass, or slightly damp grass, the battery generally lasts around 14 minutes. A fast charger comes included that will recharge the battery in around 80 minutes.

    Unlike most battery-powered lawn mowers that are made from plastic, the HYM40LI420P has a metal body. It feels very durable, but the weight is also increased as a result. Weighing 19.9 kg, it’s reasonably heavy as electric lawn mowers go.

    It has a mulching function as well as a 45 L grass box.

    Overall, this is one of the best battery-powered self propelled mowers on the market. It has a lot more power than many battery-powered mowers and is quite well equipped to deal with tougher lawn conditions. The battery will generally be sufficient for mowing medium-size lawns.

    Pros

    • Assembly only requires four screws to connect handles
    • Steel construction feels robust and durable
    • The battery life is displayed whilst mowing so you’ll know when you need to stop and recharge
    • Battery can last up to 30 minutes in standard grass
    • Able to cope with longer/thicker grass (although runtime will be reduced)

    Cons

    • On bigger gardens may need to stop and recharge partway through
    • No speed control and this may be too fast for some users
    • Heavier than most electric lawn mowers

    With a Briggs and Stratton 300E engine, the Sprint 2691794 420SP Self-propelled Petrol Lawn Mower is a powerful, yet reasonably compact, petrol mower.

    This mower has a 41 cm cutting width which makes it suitable for most medium/large gardens. It’s powered by a 4-stroke, 125 cc engine, and there are six cutting heights to choose from. The cutting heights are easy to adjust using the levers on the machine. The handle height can be adjusted as well, and it can also be folded to reduce the space it takes up in storage.

    Design wise, is compact and can be easily assembled in just 10 minutes. Even though it is constructed from alloy steel, it only weighs 25.2 kg which is reasonably light for a petrol mower; therefore, it is quite easy to carry and transport.

    In fact, it’s the best self propelled mower if you want a quality petrol model which is still fairly light – it’s the lightest metal mower with a petrol engine featured on this page.

    On top of its manageability, one of the best things about this mower is how easy it is to use. It works well in both wet and dry weather and the self propelled speed is suitable for most gardeners.

    This mower also comes with a 60 L grass collection bag that makes it suitable for most lawns. The clippings can either be collected in the grass bag, mulched, or discharged from the back of the mower.

    Overall, this is a powerful but compact petrol mower. It offers the power of petrol, but in a lighter, more manageable body which is easier to lift and control.

    Pros

    • Works well in both wet weather and dry
    • Self-propelled function is a good speed for most gardeners and makes the mower easier to control
    • Lightweight for a petrol mower at 25.2 kg makes it manageable
    • Easy to assemble in around 10 minutes
    • Cutting height and handle are easy to adjust using separate levers

    Cons

    • Grass bag can be difficult to attach to the frame, needs to be stretched into place
    • No oil included so this will need to be purchased separately

    Self propelled mowers aren’t exclusively for bigger gardens. The Mountfield SP41 Petrol Lawnmower, Self-Propelled is one of the best mowers if you want a self propelled model in a smaller garden. It’s designed for spaces up to 250 m² (although it could doubtless handle medium gardens too!).

    This lawn mower has a 39 cm cutting width which makes it one of the narrowest mowers featured here. One benefit of this is that it’s easier to manoeuvre around garden furniture, flowerbeds and trees. Plus, it can be navigated up smaller pathways. There are five cutting heights to choose from, ranging from 22 – 80 mm, as well as a 40 L grass collector.

    Despite the smaller size, it’s still powerful, with a 123 cc Stiga auto choke engine.

    It’s made predominantly from plastic which gives it an overall weight of just 21 kg. It’s the lightest petrol mower featured on this page, and therefore one of the best self propelled mowers if you want a petrol mower that is extremely manageable. Most gardeners should find this mower easy to move in and out of storage even when the self propelled feature is switched off.

    However, customers have reported a couple of minor drawbacks to this mower’s design. Firstly, it seems it doesn’t work well if the grass is damp, despite its high cutting heights, as the cutting deck can clog easily. Also, the self-propelled speed is reasonably fast, so you may need to be prepared to walk quickly!

    Nevertheless, due to its size and power, this is a great option for small/medium gardens. It delivers the power of a petrol mower, whilst being light enough to be easy to manage. The compact design and lightweight construction mean it shares many of the benefits of an electric model, without the faff of charging batteries.

    Pros

    • Lightest petrol mower featured here - easy to manage and manoeuvre
    • 39 cm cutting width is reasonably compact so it’s good for smaller gardens and narrow pathways
    • Starts usually after just one or two pulls
    • Easy to assemble with no extra tools required

    Cons

    • Not suitable for use on damp/wet grass as it may become blocked
    • Self propulsion may be a little fast for some people

How to Choose the Best Self Propelled Lawn Mower

Uneven ground can certainly result in more of a workout whilst mowing the lawn.

If you’ve got slopes, bumps or hillocks in your garden, you’ll find that a self-propelled lawn mower makes them a lot easier to manage.

By pulling themselves forwards, a lot of the effort is taken out of negotiating the mower over lumpy terrain.

There are quite a few different things to consider when choosing the best lawn mower for uneven ground, so the following information should help you make an informed decision.

Power Type

When looking for a self-propelled lawn mower, you have the choice between petrol-powered models, mains-powered options and battery-powered machines. There are advantages and disadvantages to each type, which we’ll look at in more detail below.

Petrol-Powered

Owning a self-propelled lawn mower that is powered by petrol means that you have the freedom of cordless mowing, combined with the vast power of a petrol machine.

Petrol lawn mowers are very powerful. They’re generally capable of cutting through long, thick grass, and won’t bat an eyelid if it’s slightly damp either. Due to their large engines, petrol machines are heavy, and therefore can be difficult to manoeuvre around the garden.

Being self-propelled can certainly help with this, pulling the mower around and over difficult terrain. This can allow petrol mowers to be used in gardens where it might otherwise be too challenging for such heavy machinery.

Nevertheless, petrol mowers might not be suitable for those who struggle with lifting heavy objects, or for gardens with lots of steps and different levels. Moving a large, heavy petrol lawn mower between sites can be hard work when the ‘self-propel’ can’t be used.

Mains-Powered

Mains-powered mowers tend to offer a good middle ground between petrol- and battery-powered mowers.

They don’t produce fumes like petrol machines, and are better for the environment, but they’re generally more powerful than battery-powered models (although, in recent years, there is more crossover between mid/low range mains-powered machines and mid/high range battery-powered machines).

The biggest downside of a mains-powered mower is the small fact of being tethered to a power socket by a cable. Not only can this be limiting in terms of how freely you can move around the garden, but you also need to be constantly mindful not to run over the wire.

Having a self-propelled, mains-powered lawn mower is useful because you can keep mowing until the job is done, and the propulsion will help reduce fatigue; however, you have to work around being restricted.

Battery Powered

As mentioned above, battery-powered technology has come on leaps and bounds in the last few years. Better availability of larger, more powerful batteries now means that battery-powered machines can better keep up with mains-powered models.

Of course, there’s always going to be a time limit on using a battery-powered lawn mower, and this is one of the biggest disadvantages.

Large batteries, of around 6.0 Ah, can often achieve up to an hour’s run time (and sometimes more than that). However, these will generally need to be bought separately and can be expensive.

For this reason, battery-powered lawn mowers might be considered more suitable for smaller gardens, unless you’ve budgeted to buy larger batteries.

Another good point about battery-powered self-propelled lawn mowers is that they are some of the most lightweight mowers available. As a result, they are much easier to move around the garden, lift up steps, and haul over obstacles than heavy petrol/mains-powered models.

Propulsion Speed

Although this is something you don’t have to think about with non-propelling mowers, propulsion speed is worth bearing in mind when shopping for self-propelling models.

Some mowers may only offer one speed, which they should cite in their description or product specifications. A useful statistic to bear in mind is that ‘comfortable walking pace’ is generally considered to be 4.5 – 5 km/h.

There are self-propelled mowers available with more than one speed which can be useful for several reasons. Firstly, so that you can move at a speed that you feel comfortable with, and secondly so that you can apply a bit more ‘oomph’ when tackling bumpy, hilly terrain.

Garden Size

If you only have a small garden, you will likely find that a large, petrol-powered lawn mower is too much for you. Not only because of its size, but because the cost of the machine won’t be justified.

Lawn mowers also have different cutting widths and getting the right size can depend on the size of your garden.

Large lawn mowers have a cutting width of between 46 – 53 cm. These are great for medium/large gardens as it means less passes need to be done across the lawn in order to cut the whole space. However, this large size can be a hinderance in smaller gardens, limiting manoeuvrability and also making it hard to mow in tight corners.

Smaller lawn mowers can have as narrow a cutting width as 30 cm. This may be too small for even a lot of medium-size gardens, because you’d have to do a lot of passes with the mower. However, it can be useful in small gardens and gardens with narrow pathways. Cutting widths ranging from 30 – 45 cm should be suitable for smaller gardens.

Methods of Grass Collection

Most mowers will have a range of options when it comes to grass collection.

As standard, you can expect a grass bag that can be emptied into the compost, but you might also want to check if the mower comes with a mulching plug.

Mulching the grass will result in the finely-cut clippings being spread back over the lawn as the mower goes. This helps fertilise the grass and can help with lawn health. It also means that you don’t have to keep stopping to take grass clippings to the compost heap.

When grass is collected in a collection box, it adds to the weight of the mower. This also makes it harder to push, and can slow down the self-propulsion speed, so having an option to mulch can be useful.

Self Propelled Lawn Mower FAQs

Which is better for uneven lawns, lawn mowers with front- or rear-wheel drives? 

There’s advantages to both front- and rear-wheel drive mowers, but it’s generally believed that rear wheel drive is best for hilly gardens and uneven ground.

Rear wheel drive lawn mowers provide better traction which makes them a good option for slopes and hills. They run on the back of wheels, and not the front ones. You’ll have greater control over crooked, bumpy and uneven gardens.

Can you go backwards with a self propelled lawn mower? 

Most self propelled lawn mowers can’t move backwards when they are in use. They can be moved backwards if you disengage the blade and drive motor, but to move them backwards while in use, you’ll need to raise the wheels off the lawn.

As always, read the manufacturer’s instructions carefully and follow the advice given for your particular lawn mower model.

What petrol should I use in my petrol lawn mower? 

You should use clean, fresh, unleaded petrol in your lawn mower (unless the manufacturer recommends otherwise).

If the fuel is more than three months old it will likely have gone stale. Stale fuel doesn’t easily combust, and the machine will not work as well.

Check the ethanol content of the fuel. Fuel with an ethanol content of up to 10% is ok to use, but some fuels contain 15% ethanol which should be avoided.

Can you still manually push a self propelled lawn mower?

Yes, in most cases you can still push a self propelled lawn mower. Many gardeners prefer to turn off the self propelled function when they need to move slower, such as around trees, flower beds or obstacles like garden furniture.

The only issue is that pushing a self propelled mower can be much harder work than pushing a regular mower. This is because self propelled mowers are usually heavier, as the weight is less important. Many have a heavier chassis and are packed with extra features that add to the weight.

What are the pros and cons of a self propelled lawn mower?

Self propelled mowers help mow large lawns in less time, with much less effort. Pushing a large mower across a big lawn, particularly if there is uneven ground or inclines, can become tiring very quickly.

Self propelled mowers literally take the hard work out of mowing; the mower will feel practically weightless. Self propelled mowers are easier on your body, and all you need to worry about is steering in the right direction.

They move a lot faster than you would with a push mower, and can help produce a smoother finish. This is because there’s no struggling up slopes, which can lead to an uneven cut. Self propelled mowers move consistently and smoothly.

There aren’t many downsides to self propelled lawn mowers. However, as you might expect, they are more expensive than regular push mowers. They are usually heavier, which means that getting them in and out of storage can be harder. However, there are models under 25 kg on the market which are more manageable, particularly if you’ve got a long way to push your mower before you get to your lawn.
