Petrol lawn mowers provide some unique benefits when compared to their electric counterparts.
Being cordless makes them incredibly convenient to use and perfect for larger gardens where there isn’t a nearby power supply.
If you’ve only ever used electric mowers, then you might not be aware of the benefits of using a petrol mower. The most obvious benefit is the lack of power cable.
Having to find an accessible power supply nearby is one of the biggest headaches of using an electric lawn mower and often results in the need to use one or more extensions leads. You simply don’t have this problem with a petrol mower. It has an engine and is powered purely by petrol.
A lot of petrol mowers are also self-propelled, meaning you don’t have to use any effort or strength to push them forward. This is perfect if you have a bad back or just don’t want to exert a huge amount of energy when mowing your lawn.

We’ve rated some of the best petrol lawnmowers currently available on the market – looking at their key features as well as the pros and cons of each model.
Easy-to-use yet powerful – perfect for medium-sized gardens
Cost: Price not available
The Hyundai Self-Propelled Petrol Mower is our best pick for several reasons. Firstly, it’s self-propelled, making it very easy to use since the mower does most of the work for you. Some self-propelled mowers can move too quickly and make you feel as though you’re being dragged along but this is not the case with the Hyundai, which moves at a natural walking pace.
Another great thing about this mower is there are no tools required to assemble it. This not only makes it easy to assemble initially but you can also fold down the handles for easy storage without the need for accompanying tools.
It’s powered by the Hyundai OHV 4-stroke Euro 2 engine, which is plenty powerful while still being low emission and easy to maintain. It’s also very easy to start due to the contactless ignition system. It has a cutting width of 42cm and is best suited to small and medium lawns.
Overall the Hyundai is a superb choice, whether you’re purchasing a petrol mower for the first time or looking to upgrade from another model.
- Self-propelled making it very easy to use and ideal for gardens that are on an incline
- Large grass collector means you can mow for a long time without constantly worrying about emptying
- Quick and easy assembly with no tools required
- Contactless ignition system makes it very easy to start
- Height adjustment can struggle on uneven lawns
- At 28kg it’s a considerable weight, even for a petrol mower
An affordable and robust mower that’s perfect for those on a tight budget
The Yard Force Push Rotary Lawn Mower comes with most of the features you would expect from a petrol mower in its price range. In addition to having a central height adjustment that lets you set the blade at 5 different heights, it also has a generously sized grass collection bag and a robust steel deck – making it suitable for most lawns.
The Yard Force mower features a 125cc Briggs and Stratton engine, making it high powered, reliable and low emission. It’s easy to start and Yard Force claims it’s perfect for use on lawns up to 400m2 in size.
As you’ve no doubt discerned from the name, this mower isn’t self-propelled so if you’re looking to reduce the physical labour of mowing then this might not be the ideal choice. That being said – the soft grip handles do make it comfortable to use, and it weighs considerably less than a lot of other petrol mowers, including the Hyundai model featured above.
- The Briggs and Stratton engine makes it a powerful, reliable and robust mower
- Available at a very reasonable price
- The 45-litre grass collection bag with full level indicator means less time spent emptying
- Not being self-propelled makes it somewhat arduous to use, especially for older users
- It can be difficult to find replacement blades
- This model isn’t as feature-rich as some other models close to its price range
A solid and reliable mower that’s reasonably priced
The Mountfield Petrol Rotary Lawn Mower might not have as many features as some other mowers we’ve rated but it is a very reliable model that gets the job done.
You can choose from either a standard Mountfield engine or a 125cc Briggs and Stratton 300 Series OHV. Having this choice is certainly a big bonus with this model since Briggs and Stratton are renowned for their powerful and reliable motors.
There is a 40-litre grass collector, which is admittedly on the smaller size; 5 different cutting positions (25-70mm) and a 39cm cutting width. It has a recoil rope system, standard for petrol mowers and is suitable for small to medium-sized gardens.
Overall, it’s a solid machine that gets the job done, even if it isn’t quite as feature-packed as some other models in its price range.
- Comes with the option of a Briggs and Stratton engine – giving you a guarantee of reliability and good performance
- Light and easy to use
- Well made and performs well under most conditions
- The 40-litre grass collector is quite small compared to other petrol mowers in this price range
- Being hand-propelled means it does require some effort to use
Comfortable to use with an array of built-in features
Cost: Price not available
The WEBB R41SP is a self-propelled mower with a 2-in-1 cutting system and 5 cutting heights ranging from 20mm to 75mm. The soft-grip handles make it comfortable to use and being self-propelled removes a lot of the manual labour, which is always a welcome addition.
The 50-litre grass collector is another welcome feature and means you spend less time emptying and more time mowing. It’s also very easy to assemble, which isn’t always the case with petrol mowers.
It has a Sanli 118cc 4 stroke engine and a robust steel deck, so you can rely on it to perform well and withstand heavy use. The cutting width is 40cm.
Overall, it’s a very solid machine and would be suitable for those with small to medium gardens who are looking for a mid-priced machine.
- A large grass collector of 50 litres
- Self-propelled making it perfect for those who want to reduce the labour associated with mowing
- Easy to assemble regardless of experience
- Fairly heavy at 27kg, which can make it tough to move

It comes with some generous features for its price range, including 9 different cutting heights, a 50-litre grass collector and a cutting width of 46cm. Having these features makes it perfect for larger gardens where there’s a lot of grass to be mown. The fact that it’s self-propelled also makes it much easier to use on larger areas.
It has a height-adjustable long handle and is recommended for gardens up to 1,400 square meters. The handle is also foldable, making it very practical and easy to store. You simply loosen the two-star screws and it folds down. It’s a rear-wheel-drive mower, which makes it very energy efficient and easy to handle.
The Einhell GC-PM 46 S is an excellent choice of petrol mower overall. Although it costs more than the other mowers on this list, you really see where that extra money goes, and for larger lawns especially, it’s an excellent machine.
- 9 different cutting heights make it easy to get the exact look you want for your lawn
- The 50-litre grass collector is very generous and makes it perfect for larger gardens
- The foldable handle makes it very easy to store

How To Use A Petrol Lawn Mower
Using a petrol lawn mower isn’t particularly difficult but there are certain things you should be aware of if you’ve never used one before.
The first thing to mention is that you should always read through the instructions that come with your mower. It can be easy to neglect this step, particularly if you already have plenty of experience using petrol mowers. However, not all models are the same and there might be something important you need to know that’s unique to your particular model.
For safety reasons, petrol mowers aren’t filled with any fuel when they’re shipped. This means you’ll have to fill it up before the first use. When filling the tank with petrol be sure to do this well away from your lawn since any spilt petrol will burn the grass. You’ll also need to make sure there’s enough oil in the mower before you start using it.
Before you start mowing, you’ll want to set the blade to the correct height. The required height of the blade will depend on how long the grass you’re cutting is. The longer the grass, the higher the blade will need to be set.
To achieve an even cut, you should start at the edges of the law and go all the way around once. You can then go from the top to the bottom to cover the central area of the lawn. Be sure to look out for any stones or large twigs when you’re cutting the grass since these can easily damage your mower.
You’ll want to empty the mower bag regularly as you’re cutting, particularly if you have a very large lawn. Always make sure you turn the engine off before removing the bag.
How To Maintain A Petrol Lawn Mower
Petrol lawnmowers are designed to be easy to use but they do require some maintenance to ensure they work optimally and to prevent any faults from developing.
Below are the main areas to focus on when it comes to maintaining a petrol lawnmower –
- Cleaning – Cleaning is one of the most important aspects of lawn mower maintenance. If the bottom of your mower is caked in grass, then it’s going to affect how well it cuts the grass and will also mean it uses more fuel. It’s easy to cut corners when cleaning the grass off your mower but it’s worth the extra time it takes to make sure it’s completely free from any grass. Immediately after use, you’ll want to remove any excess grass from the blades and deck. After a while, it’s easy for dried grass to accumulate so you should routinely give it a thorough clean.
- Blades – The next thing you’ll want to check on your mower are the blades. The sharp part of the blades will be on opposite sides to each other and you want to check that they’re sufficiently sharp and don’t have any major dents in them. If they do need to be sharpened, then you can either take them to a professional or do it yourself if you have the tools and know-how.
- Oil – This step is very easy and is simply to check that there’s enough oil in your mower. Petrol mowers require very little oil to run but you should check this regularly since its vital for the engine to run properly. Checking the oil is literally just a matter of removing the dip stick to check it’s at the appropriate level. If not, then top it up as required before use.
- Bolts – Lastly you should ensure that all the bolts on your mower are tightly fastened, particularly those on the handles. Because lawn mowers vibrate so much, it’s easy for bolts to become loose, so it’s certainly worth checking them periodically.
