Petrol Lawn Mower Reviews: A Closer Look at My Top Picks


As I said at the beginning of this article, the term best petrol lawnmowers mean something different to each and every person.

To some, their opinion would be based on price. For others, it would have to be easy to start, be reliable, have a mulching plug, be a self-propelled mower, etc.

As such, I’ve picked 7 models based on price, features, ease of use, performance and reliability.

I’ve tried to include something for everyone.

1. Mountfield SP41: The Best Petrol Lawn Mower For Most People

mountfield sp41 review

Check Today’s Price


Key Features

Engine: 100cc, 4-stroke; Cutting Width: 39cm; Grass Box Capacity: 40 Litres; Weight: 20kg; Self-Propelled: Yes; Warranty: 2 Years;


If you consider the best petrol mower to be easy to use, does a job well and reliable, all without breaking the bank, then the Mountfield SP41 is an excellent choice.

It feels reassuringly well built and is powered by a very reliable (and quiet) 100cc OHC petrol engine which started first time, every time in my tests.

Combine this with its 39cm cutting width, 5 cutting heights, ranging from 25mm-70mm and the fact that’s it’s a self-propelled mower and which is suitable for medium to large lawns of up to 400sq meters.

How you deal with grass clippings is up to you. You can;

  1. Collect them in the 60-litre grass collector
  2. Rear discharge long grass

It’s not perfect though. The self-drive is set to a single speed so you’ll either have to keep up with it or slow down for it, depending on how quickly (or slowly) you walk. and it won’t leave a striped finish.

That said, it is very well priced, very easy to use and leaves an excellent finish

2. Cobra M41C: A Very Decent, Cheap Petrol Mower

cobra MC41C

Check Today’s Price


Key Features

Engine: 98.5cc, 4-stroke; Cutting Width: 41cm; Grass Box Capacity: 50 Litres; Weight: 19kg; Self-Propelled: Yes; Warranty: 2 Years;


Whoever said petrol mowers had to be expensive?!

If you’re on a fairly tight budget, then the Cobra MC41C gets my recommendation.

Of course, cheap products are rarely the best products and you can definitely say the same here because it’s not perfect.

However, it’s 98.5cc Cobra DG350 OHV petrol engine is easy to start and plenty powerful enough to tackle a medium sized garden of up to 400sq meters in size, provided they’re in semi-decent condition.

It has a 41cm cutting width and 7 cutting heights which range from 25mm-75mm. That, combined with the 50-litre fabric grass bag means you should be able to get through the job fairly quickly.

If your lawn resembles more of a paddock though, it’ll struggle. It’s just no powerful enough to cope with that kind of demand.

At 19kg it’s lightweight and easy to manoeuvre too. Which is a good job because it’s a hand push mower and lacks the self-propelled features of other mowers in this list.

That being said, it’s reliable, easy to use and the cut is better than I expected.

Another big benefit is that it comes with a 2-year warranty which is pretty much unheard of for a mower of this price.

3. Frisky Fox PLUS 20″: Packed With Features at an Excellent Price

Key Features

Engine: 173cc, 4-stroke; Cutting Width: 51cm; Grass Box Capacity: 50 Litres; Weight: 35kg; Self-Propelled: Yes; Warranty: 2 Years;


Granted, Frisky Fox might not be a brand that jumps straight to mind when looking for a petrol mower. However, trust me when I say, this mower is absolutely packed with features while still being very affordable.

Powered by a heavy-duty 5.5hp, 173cc Wolf ‘Dynamic’ 4-stroke OHV petrol engine, the Frisky Fox is a self-propelled mower which gives you full control over the ground speed. That means you can cut the grass at a speed which suits you.

It also provides enough power to blast through tough, long or wet grass and the steel cutting deck gives you the confidence that it’ll last.

With a 51cm cutting width and 50-litre grass bag, it’s better suited for medium to large lawns.

You don’t just have to collect the grass cuttings either. You can also discharge them from the side (good when mowing long grass) or mulch them back into the turf (to recycle the nutrients).

You can choose from 7 cutting heights which range from 25mm – 75mm and to top it all off, it comes with a lawn striper in form of a thick rubber strip at the rear of the machine.

OK, the striping effect isn’t as good as you’d get with a rear roller but still, it works pretty well.

As I said, Frisky Fox isn’t a name you’d think of when shopping for a petrol lawnmower but like I say, it’s packed with features and comes in well under £250.

4. Einhell GC-PM 46 S: A Decent Pick For Larger Lawns

a good value for moey petrol mower

Check Today’s Price


Key Features

Engine: 139cc, 4-stroke; Cutting Width: 46cm; Grass Box Capacity: 50 Litres; Weight: 34kg; Self-Propelled: Yes; Warranty: 2 Years;


If you have a large lawn but still don’t want to break the bank, the Einhell GC-PM 46S is a good choice.

Firstly, it’s powered by a 4-stroke, 139cc Briggs & Stratton engine which better in longer, wet grass that the previous models.

It’s a self-propelled mower, driven by the rear wheels which can be disengaged if needed so you can use it like a push mower.

The cutting width is pretty wide at 46cm and 50-litre grass bag which can tackle a large lawn without issue.

There are nine cutting heights ranging between 30mm to 80mm. The cutting height adjustment is made easy via the lever at the rear wheel.

It has a powder-coated steel deck too which makes it very robust and it’s reassuringly heavy at 34kg.

The self-propelled feature works well in the open but is a little quick when working in tight spaces. This is why you can disengage the drive from the rear wheels but it does it feel a bit heavy.

Overall though, it works well and this mower offers excellent value for money.

5. Hayter Harrier 48 (Code: 476A): The Best For Creating Immaculate Lawn Stripes

the very best petrol mower

Check Today’s Price


Key Features

Engine: 163cc, 4-stroke; Cutting Width: 48cm; Grass Box Capacity: 70 Litres; Weight: 44kg; Self-Propelled: Yes; Warranty: 5 Years;


If creating the most vivid lawn stripes is important to you, the Hayter Harrier 48 is one of the best petrol mowers you can buy.

This particular model has been updated and improved from previous versions.

It’s powered by a 163cc 675iS Briggs & Stratton engine and the electric start features ReadyStart® technology which makes it very easy to get going. Just press the starter button and off you go.

It’s quiet too thanks to a ‘performance muffler’ designed for low noise operation.

A 48cm cutting width and massive 70-litre grass collector makes it suitable for medium to large lawns and with a 7-stage height adjustment via a single lever, cutting heights from 60mm right down to 13mm.

As you’d expect, this is a self-propelled mower fitted with Hayter’s ‘AutoDrive’ technology. The drive comes from the split differential, ribbed rear roller for better traction and turning. This is also what creates the beautifully striped finish that the Hayter Harrier is well known for.

Also, the cutting deck is wider than the wheelbase. This means you can mow right over the edges of your lawn without worrying about scalping it.

The ability to change the ground speed between 1.8mph-3.3mph means you can set it to suit your preferred walking speed.

Plus, it has an easy wash port so you can attach your hose and spin the blades so it mower essentially washes itself.

The only thing missing which would make it perfect is a mulching plug so grass cuttings could be left to re-fertilise the lawn.

But I suppose we can’t have everything!

All this comes with the peace of mind of a 5-year warranty so you can be confident of excellent for many years.

As I said, this, for me is one of the best petrol rotary mowers there is.

6. Webb WERR17SP: An Excellent, Cheaper Alternative to the Hayter Harrier

a very good petrol lawn mower for leaving stripes

Check Today’s Price


Key Features

Engine: 140cc, 4-stroke; Cutting Width: 43cm; Grass Box Capacity: 55 Litres; Weight: 32kg; Self-Propelled: Yes; Warranty: 2 Years;


If the Hayter Harrier is too big and too expensive, take a look at the Webb WERR17SP.

It’s smaller in pretty much every way but it costs around half that of the Hayter and has many of the same features.

And like the Hayter, it’s British made!

It’s a self-propelled, rotary mower powered by an ever so reliable 140cc 500e series recoil start Briggs & Stratton engine which is supremely easy to start. It’s also quiet thanks to its ‘LO-TONE’ muffler.

The 43cm cutting width is plenty wide enough. It also has six cutting heights which range from 23mm to 77mm which you can adjust using the big lever to the left of the grass collector.

Talking of the grass collector, it weighs in at 55-litres, making it suitable for medium to larger lawns. Due to the design of the grass collection bag, it’s perfect for collecting leaves off the lawn during the autumn.

The Webb has 3 ways of dealing with grass cuttings so you can deal with the variable changes during the growing season;

  1. It can collect it via the collection box
  2. You can remove it and discharge it out of the back, or
  3. You can use the mulching plug to mulch it and blow the tiny, nutrient-rich back into the turf

If you like the stripy finish when cutting the grass, this petrol mower will give it to you. It has a power-driven split rear roller that makes manoeuvring it easier.

Like the Hayter, the cutting deck is wider than the wheelbase. This means you can roll right over the edges without having to worry about scalping them.

The assembly instructions aren’t great but once you get past that and get it working, the Webb WERR17SP is an excellent mower.

7. Honda IZY HRG 466 SK: Best For Reliability and Build Quality

honda IZY HRG 466 SK

Check Today’s Price


Key Features

Engine: 160cc, 4-stroke; Cutting Width: 46cm; Grass Box Capacity: 55 Litres; Weight: 32kg; Self-Propelled: Yes; Warranty: 5 Years;


If you’re in the market for a petrol mower that’ll really stand the test of time, the Honda IZY HRG 466 SK is a cracker.

It’s powered by Honda’s GCV160 OHV, 4-stroke petrol engine which, like all Honda engines, has a reputation for incredible reliability.

It starts first time, every and just keeps going and going.

The mower itself is incredibly well built while at the same time, being light enough to manoeuvre easily. Of course, it’s a self-propelled mower which helps.

It features a powder-coated cutting pressed steel deck which is resistant to corrosion and UV abrasion.

Mowing features include a 46cm cutting blade in combination which will make light work of less that immaculate grass. This is combined with a large 55-litre grass collector and six cutting heights, ranging from 20mm – 74mm.

It is fairly expensive when compared to other mowers but in my opinion, it’s definitely an investment worth making. Like I said, it’ll keep on keeping on for many years after other mowers break down.

8. Allett Classic Review (14L & 17L): The Best Lawn Mower For Ornamental Lawns

Allett Classic 14L Review

Check Today’s Price


Key Features

Engine: 87cc, 4-stroke; Cutting Width: 35cm / 43cm; Grass Box Capacity: 32 Litres / 40 Litres; Weight: 38kg / 41.5kg; Self-Propelled: Yes; Warranty: 1 Year;


The Allett Classic 14L and Classic 17L isn’t for everyone.

Not only because it’s pretty expensive but because we don’t all have ornamental lawns that we dedicate all our time to.

However, if you do have an ornamental lawn made up of the finest fescues and brown tops, then no other type of mower will give a finish like a cylinder mower.

Like the Hayter and Webb mowers I reviewed earlier, Allett lawn mowers are British Made.

That means they’re quality and this is evident as soon as you unpack it. Everything feels very well made.

It’s powered by a Loncin 87cc, four-stroke engine with recoil start. The engine is air-cooled to prevent overheating.

You have 5 cutting heights so you can cut as close as 6mm and as high as 32mm for that bowling green finish.

This bowling green finish is achieved by the 5 bladed cutting cylinder which delivers 66 per meter.

Another nice feature of the Allett Classic is that the cutting cylinder is a ‘Quick Cartridge’. This means you can easily remove it for cleaning but also to replace it with a scarifier cartridge (sold separately). There is also a single height adjustment for scarifying your lawn.

The smaller Allett comes with a 32-litre capacity grass box and the larger, model has a capacity of 40 litres.

As you’d expect for the cost, this is a self-propelled mower, powered by the rear roller.

Speaking of rollers, the Allett has two, a polyethene roller on the front and a steel roller at the rear. It’s these rollers that give your lawn the most beautiful striped finish.

It would be nice if the rear roller to be split. This would improve its manoeuvrability. But really, it manoeuvers well anyway.

You’ll also need a funnel to fill the engine with oil, otherwise, you’ll get it everywhere.

Like I said, I own an Allett Classic and I have to say, I love it.

Not only does it make my front lawn look incredible with its striped finish, but it makes me look good doing it!

It’s a pretty expensive machine. But, if you invest your time, money and energy into an ornamental lawn, you need a mower that’ll do the job right.

The Allett Classic will do it.

Why Choose a Petrol Lawn Mower?


Many lawn mowers are going the same way as cars in that more and more and becoming battery powered. Despite that, lots of lawn owners still use petrol models.

Battery powered, or cordless lawn mowers have one big advantage over regular electric mowers and hover mowers. That’s the fact that they don’t have a cord that restricts them to a power source.

They work brilliantly on smaller to medium sized lawns. However, batteries run out and need re-charging.

As such, if you have a larger area to mow, a petrol lawn mower is your best option. It won’t be restricted by a power cord or a battery that needs recharging. As longs as you’ve got petrol, you’re good to go.

Also, if you need the power to get through long, thick or damp grass, petrol lawnmowers will give it to you. Cordless and electric models that have a tendency to cut out and give up when presented with that kind of challenge.

All that being said, petrol lawn mowers do come with their downsides too.

When You Might Not Want to Choose a Petrol Mower

Firstly, compared to mechanical mowers and even electric and cordless models, petrol machines are noisy.

They can be heavy too. Although, some are self-propelling which means you don’t need to push them. You just guide them in the direction they need to go in.

Also, maintaining a petrol lawn mower is much more involved than maintaining other types.

For most lawn mowers, maintaining them just involves keeping it clean and keeping the blade sharp.

However, there’s more to do with petrol machines.

For starters, with many petrol mowers, you need to change the oil after the first five hours of use. You’ll also need to do it again after each season.

Then there’s the spark plug and air filters which need changing from time to time.

On top of that, you’ll need to visit the petrol station with your fuel can whenever it needs fuel.

Despite all this, petrol lawn mowers are still the best choice for many lawn owners.

 

Things to Consider When Choosing the Best Petrol Mower For You and Your Garden


When deciding which is the best petrol mower for you and your lawn (or even if a petrol mower is the best option at all) there are 3 things to consider.

Let me take you through them;

The Size of Your Garden

The size of your garden should tell you whether you even need a petrol mower or if you’d be better choosing a different type.

If you only have a 30m² lawn on the front of your home then there’s no need for a petrol mower. A hand push mower, cordless, even a robot mower would be better options.

However, if you have 100m² or more then a petrol mower is definitely a good option.

The Weight of the Machine

When you consider that petrol lawnmowers have an engine strapped to the top of them, you can expect them to be heavy.

Especially when compared to other types.

Some can be fairly light, weighing less than 20kg but others can weigh up to 50kg or more.

The Type of Engine

Talking of engines, you’ll want to think about the type of engine you choose.

A 2-stroke or a 4-stroke?

Well, here’s a bit of guidance…

Buy a 2-stroke mower if you want a lawn mower that;

  • Is lightweight – two-stroke engines a smaller and lighter than four-stroke engines.
  • Costs less to buy – because they’re not as sophisticated as four-stroke mowers, they’re generally cheaper.
  • Will work well on sloped lawns – two-stroke engines will run on their sides which makes them ideal if you have heavily sloped lawns. Four-stroke engines don’t cope as well.

Buy a 4-stroke lawn mower if you want;

  • A machine with more power – if you cut your lawn when it’s long and wet, or if it’s really thick with meadow grass, you’ll need more power.
  • Is easy to start – two-stroke engines can be a bit temperamental when it comes to starting them. Especially in the cold. If you want a machine that’ll start first time, choose a four stroke.
  • Easier to maintain – two-stroke engines run on a mixture of petrol and oil. That means you’ll need to mix it correctly. This isn’t difficult but a four-stroke engine is filled with oil and petrol separately which reduces the chances of human error.

Cutting Width

A feature that is often overlooked when choosing a lawn mower of any type is the cutting width.

But why is it important?

Well, it’s a question of time.

A cutting width of 20 inches is 25% bigger than a cutting width of 15 inches. This means it should take you 25% less time to mow the lawn.

If you have large lawns, choose a wider cutting width.

However, a larger cutting width means a bigger, heavier machine which might be too hard to handle ina small garden. So if you have a small garden or lawn, choose a smaller mower with a smaller cutting width.

Height Adjustment

Another consideration that often gets forgotten about is the level of height adjustment that a lawn mower provides.

Often times you’ll read reviews on amazon.co.uk and on other websites that say the lawn mower didn’t cut low enough, or high enough.

If you like a short cut, make sure the mower you’re considering adjusts to a low enough level. But also give a good finish at that height.

On the other hand, if you want a machine that’ll cope with being bounced around a bumpy lawn, choose something that’ll cut higher.

Other Features

Not all lawn mowers are made equal. Some have additional features that others don’t.

Some of the best petrol lawn mowers come with starter kits that contain oil, fuel cans and other bits and pieces.

Others have handy features like key start or electric start. Some have attachments that enable you to mulch the grass and blow it back into the lawn instead of collecting in the bag.

Some of these little extras might be important to you, they might not. Still, they’re worth considering.

Warranty & Support

Most products you buy these came come with a statutory 12-month warranty.

That said, some manufacturers offer 2, 3, even 5-year warranties.

If warranties are important to you, consider the length of the warranty when making a purchase.

 

In Conclusion


I hope you have found my list of petrol lawn mower reviews and buyers guide useful.

I have tried to choose the best petrol lawnmowers for different circumstances, for all applications and in a range of price brackets. This is what helped me narrow my top picks down to just 7 models.

However, the fact is that there are lots of really good petrol lawnmowers on the market from brands that I haven’t even mentioned.

Like, AL-KO, Husqvarna, Cobra, John Deere etc.

So use this article as a guide and make your own decision. You might even choose a completely different model to the ones I have mentioned in this article.
