Not all lawn mowers are made the same. Many of them are electric but few can rival the best petrol lawnmowers. It can take a while to cut using a low-power engine. But petrol is still one of the best choices and one of the most durable options for your lawnmowers’ engine.

Not all petrol lawnmowers are reliable. Some require a few strokes to power while others start to show signs of premature ageing after only a couple of seasons. We recommend choosing wisely as the best petrol lawnmowers might not be as affordable as you might think. But all of the research is not in vain as there’s nothing that can elevate the look of a home that a perfectly cut lawn.

    Einhell GC-PM 46/2 S HW-E Self-Propelled Petrol Mower

Einhell makes some of the best self-propelled petrol mowers as seen with its HW-E. The four strokes engine with one cylinder of 139cm3 is one of the best on the market. With the help of electronic ignition, it represents our top recommendation for a lawnmower that cuts superbly and that lasts as well.

The 1.3L fuel tank needs regular petrol for the mower to start its job. Even on large gardens, the 1.9kw motor doesn’t overheat which means it can cut for about an hour easily before taking a break. The cutting height settings come with the typical adjustability between 30 and 80mm for larger gardens with long grass. Some of these grass can be left on the lawn but there’s also a large 70l catch bag that’s included with the petrol mower.

PROS

Made with a large fuel tank

It includes a catch bag

30 to 80mm cutting height

CONS

Not so good on wet grass

    Sprint 410P Push Petrol Lawn Mower

Running on a Briggs & Stratton 300E Series 125cc motor, this lawnmower is our recommendation as a budge option. It features a full-fold handlebar which can be adjusted on 3 height levels. You get a comfortable design that can be adjusted to your height here. But we also like discharge systems. It comes with both side discharges and with a bag for collecting clippings so that you can choose how you want to take care of your lawn.

There are 6 cuts height positions for you to rely on. Most lawns find one of these heights to be just right and if you’re not preparing to mow down a football field it’s going to do a great job as long as your ground is level.

A soft mesh bag of 45 litres is added to the lawnmower. It’s not the largest bag we’ve seen and if you choose to use it, you should expect a lot of work discharging the bag. Otherwise, the lawnmower can be one of the best long-term use purchases of your home.

PROS

Made with recoil starting

Designed with a push drive system

Made with a steel mowing deck

CONS

Small mesh bag

    Einhell Petrol Lawn Mower GC-PM 46 S

The petrol lawnmower comes with a 1.9kw motor with a large 46cm cutting width. This makes it the smaller and more agile brother of the 52 S HW that features a 52cm cutting width. It’s highly efficient for small lawns and it can also be one of the preferred gardening tools of those who don’t want to use too much muscle power to make their backyards look perfect.

Cutting height is also variable depending on how you want your lawn to look. The height of the cut is what you need to take into account when you want to create the perfect lawn. If you don’t want to walk all over it all the time, you can easily allow it to grow a little bit more.

We also like the daily practicality of the lawnmower. For example, it has a starting cable that’s attached closed to the grip handles so that you don’t have to bend down risking some serious back pain issues after a long day mowing the lawn.

PROS

Made for lawns of up to 1,400m²

Designed with a 50L grass catch bag

Disengageable Rear-Wheel Drive

CONS

A bit heavy for its cutting width

    Hyundai HYM510SP 4-Stroke Petrol Lawn Mower

This self-propelled 4-stroke petrol lawnmower features a 51 cutting width. It can be your designated choice if you plan to take care of large lawns. Both its cutting width and its 70L plastic polyester bag make it one of the largest grass cutting machines.

Recommended for lawns above 2000sq. ft., the lawnmower comes with a foldable handle which also helps with storage. Since it’s a bit heavier than its 139cc Hyundai alternative, this 196cc lawn mower is among the best for thick lawns that have been taken care of for years.

It might also be appealing to those who want to cut the grass a bit shorter since its lowest cutting height sits at 25mm. Its maximum cutting height of 75mm is a bit shorter than on other lawn mowers as well. Made with 4 variable speeds, this self-propelled machine isn’t too difficult to push around either. The added soft-grip handlebar makes user interaction a bit more pleasant through regular use.

PROS

Designed with a mulching plug

It includes a side grass discharging cut mode

Used with or without a self-propeller

CONS

Heavy for some users

    Einhell GC-PM 40 S-P Self Propelled Petrol Lawnmower

If you like lightweight lawn mowers, you need to consider this 99 cm³ Einhell motor of 1.2kW. It can be your best friend on small lawns. But most of those buying it consider this grass cutting machine due to its low weight when they need to carry it up or down the stairs since it only has 18.5 kilograms. This makes it half as heavy as most of its alternatives and a good tool if you don’t have any help when it comes to moving into storage.

Its reduced size also comes with a smaller cutting width. It cuts grass in a 40cm width that makes it a suitable solution for smaller gardens with small lawns. The manufacturer defines these spaces as lawns of up to 1,000 m².

Based on rear-wheel drive, this best petrol lawn mower comes with 5 height adjustments. These cover one of the best pallets of cut from 25mm to 60mm.

PROS

It cuts grass down to 25mm

Very lightweight

Made with an ergonomic folding handle

CONS

Small fuel tank

    Murray EQ300 Self-propelled Petrol Lawn Mower

Based on a reliable Briggs & Stratton Engine engine, the Murray Push Mower is a simple performer which is used for all types of grass cutting. It works with high build quality rear discharge which can be useful when you want to grow a thicker lawn or with collecting of clippings when you want to clear the lawn of the cut grass.

The height adjustability of this gasoline lawnmower also impresses. It cuts from 28mm up to 92mm making it one of the truest options in its class when it comes to the overall height adjustability. It also comes with 18cm large wheels which makes it easy to manoeuvre in tall grass.

PROS

Based on recoil start

41cm cutting width

Based on a Briggs and Stration petrol engine

CONS

Single-speed design

    McCulloch M40-125 Petrol Push Collect Lawn Mower

The 125cc petrol push lawn mower is a small performer designed with a 40cm cutting width. Made with a powder-coated steel body, this small grass cutting machine is resistant and reliable for years.

What we like most about it is that it’s a bit quieter than most of its alternatives. This is why we saw it as a possible option for those who can’t make too much noise on their lawn such as those living in urban areas with strict restrictions. Based on a small motor, this gas lawn mower also doesn’t need too much force to move out of storage as it’s lightweight at just 23kf.

PROS

It collects grass clippings

Made with a reliable engine

1600w power

CONS

Small 40cm cutting width

How to buy the best petrol lawnmowers

When you want to buy a new petrol lawnmower, you need to look at the options you have at the moment since new ones come out every year. You’ll notice many of these are made with parts from different brands. The biggest issue manufacturers in this segment have is developing a strong motor and as a result, they end up using motors from proven companies that have the know-how and the ability to produce such powerful petrol motors. Here’s what you need to look at when choosing a new petrol lawnmower.

Assembly

All lawn mowers come in a box, unassembled. It might take a few hours to assemble and you need to know how to do it yourself or ask a professional to assemble it for you. In theory, there aren’t too many steps that go into the assembly process.

You first need to mount the handlebar, which is often folded. One installed, you can proceed to remove any labels and printed information attached to the machine and especially those around the engine.

If your lawnmower already has the cutting blade mounted under the steel deck, you can proceed to add gas and engine oil to it. We recommend reading the user’s manual to see what type of petrol your lawnmower takes. You might also need to look at the type of oil that works for your engine. It’s generally assumed that the first oil change needs to be considered faster, but this also depends on the engine of your lawnmower.

Before you power it for the first time, you should also consider all of the essential factors that go into its safe usability. Each of them comes with a thick user’s manual and you should read it properly for safety information. For example, this is where you find crucial information on what surfaces the machine can be used on and what can happen if you try to use it on rocky surfaces.

Size and weight

As you can see from all of the grass cutting machines listed above, the size and the weight of the lawnmower varies tremendously. The lightest performer has around 18kg while the heaviest performer has more than.

On paper, this weight means nothing. But in reality, a heavy lawnmower limits its usability and practicality around the house. For example, you won’t be able to live a 40kg lawnmower and take it up the stairs if you keep it in the basement. This is why we recommend getting a garden shed if your lawnmower is heavy and if you have space for it.

The size of the lawnmower is also impressive. When you mount the handlebar (a typical operation on all new lawnmowers) you need to consider where you’re going to store it as keeping it outdoors is not an option. As a result, we recommend a shed that is large enough for your lawnmower and for all other gardening tools you need.

Starting mechanism

The way you start a petrol lawnmower isn’t too important but enthusiasts would argue things are a bit more different. It takes a bit of effort to start a petrol lawnmower after it has sat for a long time, but otherwise, it’s an easy operation.

Start button

The start button is one of the most important modes of getting the engine of the lawnmower to power on. Elegant, simple, and efficient, this starting method is seen on an increasing number of machines. Key start and electric start engines go hand in hand.

Automatic choke

The automatic choke and the power cable option is also popular on petrol mowers. It’s a bit more old-school but it’s still an easier design and alternative to corded electric lawn mowers that need to deal with long power cables.

Cutting height adjustments

What’s the minimum height of the grass on your lawn? What is its maximum height? These questions are only answered by your lawnmower. The lowest height of just below 30mm and the tallest settings of over 80mm on adjustable lawn mowers allow you to set your preferences.

Adjusting height on the lawnmower is also easy. There’s a manual single lever with a level indicator that goes up and down on most machines and you can have grass that looks completely different with a small adjustment in this area.

The height of the grass on the lawn should also be considered when it comes to the overall look of your garden. But you might not be able to cut the grass too short if your land is uneven. Some of the best petrol rotary lawnmowers can go over small obstacles. But uneven land will create uneven grass and you might need to consider first preparing your lawn properly before purchasing the lawnmower in the hopes of creating the perfect green space around your house.

Self-propulsion vs push lawn mowers

Have you ever thought about self-propulsion and how it makes your life easier? Based on a powerful drive belt, self-propulsion helps you mow in less time and more efficient. It can be one of the biggest features to consider when you have a large lawn which even exists on cordless lawnmowers.

Push lawn mowers are still capable. Most of those you see at the neighbour’s are push lawn mowers as they tend to be cheaper. They are also made for small and larger lawns. If you don’t have a lawn of 1,000 square meters, it might be time to consider one of these simpler and more affordable designs yourself.

When it comes to the durability aspect, you also need to know a self-propulsion system has higher chances of failing in the future. The good news is that even if this happens, the lawnmower is a fairly low tech machine that can be easily serviceable.

Grass box size

Grass bag sizes for grass collection include from 40-litre, 50-litre, 55-litre, 60-litre, and 70-litre grass collector capacity. You need to find the one which is right for you but there’s a catch. Even if you buy the machine with the largest grass box, you might still need to empty it before its full.

Emptying the grass box is an operation that you’ll do more frequently than others even on top Amazon lawnmowers such as those made by Mountfield, HRG, Briggs and Stratton (an alternative to Honda engines),  Hayter, Izy, Cobra, Honda or Hyundai.

The grass collector is not technically a collection bag either, it just looks like one. Most lawn mowers now come with textiles that are shaped like a collection box and that are added to the rear of the lawnmower. They don’t add as much weight as a plastic box would to the machine and they also tend to last longer.

Clippings

You might need to think about what you do with the clippings. You can connect a grass box to collect all of them and simply put them in the bin. But you might also want a lateral discharge petrol lawnmower that allows you to use clippings as a fertilizer and enjoy a better lawn in a few years.

Clippings can also be collected once on the grass with dedicated machines, but this takes a bit more time and it doubles your working effort. As a result, you should think about what your plan is with the clippings before you make the purchase.

Typical lawn mower maintenance

As with all types of 4-stroke engines, maintenance is required from time to time. Most lawn mowers are now made with low maintenance and you shouldn’t be doing much if you’ve properly used them and if you’ve properly stored them. Here’s what needs to be done.

Overall cleaning

After each mowing session, you should take some time to clean the lawnmower. You can pull start clearing clippings dirt and dust from the engine, which sits high on the machine. The lower part of the lawnmower and its wheels can be cleaned next. You also want to ensure the grass box is also clean before putting your lawn mower back into storage.

We don’t recommend pressure washing your lawnmower. You should only be interested in cleaning it on a surface level as water is one of the main enemies of engines and other metal parts of the machine that can rust.

Oil changes

Good oil is essential to the functionality of any engine. This is also the case of lawnmowers. You should add clean engine oil to it and you should also replace it when it starts to get dirty or at the oil change intervals recommended by the manufacturer.

Oil changes are going to ensure your engine runs smoothly. You should not use old engine oil or cooking oil in your petrol lawnmower. Engine oil is not expensive and you can easily buy a good product at a fair price so there’s no point of looking for savings in this area.

Petrol replacement

In most cases, petrol consumption is low on lawnmowers. However, if your petrol has been sitting in the lawnmower for a long time (typically more than a year) it might need to be changed if the engine doesn’t start. Depending on your lawnmower, you might be able to drain it quickly through a dedicated valve.

Some people use a mix of oil and petrol to fuel their lawnmowers. We haven’t tried this method ourselves and as long as manufacturers don’t recommend it, we prefer to stay away from it. We prefer to use petrol with a minimum octane level recommended by the manufacturer. This is the only true method of protecting the motor and from ensuring it lasts for years.

You can buy petrol at your local gas station. But you should know you only need a few litres for the average lawn that is up to 1,000 square foot and this petrol can last for a few mowing sessions. We always recommend safely storing petrol around your house in a cool place, away from direct sunlight and away from other sources of heat.

Spark plugs cleaning

Spark plugs might need cleaning and even replacing from time to time. If your engine doesn’t start, it might be a sign that you need to look at the spark plugs. These are similar to the spark plugs used in your car as they offer the best option for electric engine ignition.

Cleaning the air filter

The air filter also tends to get clogged in time. Debris and even clippings end up on the filter. As a result, air intake is reduced and you might be attempting to start your engine in vain. In reality, you only need to clean the filter once every few years. But we recommend checking it from time to time just so that it’s not blocked by dirt build-up./

Cutting blade maintenance

The cutting deck will start to get dull or it will get damaged in time. You can order a replacement easily online and you can even change the blade yourself. Some people prefer to sharpen their blade at home from time to time. But you also need to look at what the manufacturer recommends for its blade as it’s the most important part of the lawnmower.

Frequently Asked Questions


Why choose a petrol lawnmower rather than electric?

A petrol lawnmower is superior in terms of independence. You don’t need to bring out a large extension pull cord to your garden as you do with an electric lawnmower. If you’re thinking about battery-operated electric lawn mowers, you also need to take battery charging time into account. This can limit the freedom or the time in which you can use the machine around your house. A petrol lawnmower only needs gasoline to work when needed.

How much fuel does a petrol lawnmower use?

You can expect very low petrol consumption on modern lawnmowers. Up to 2 litres per 2,000 square feet seems to be the accepted fuel consumption, depending on the motor and on the time it takes to mow this surface. But most users have leftover gas in the tank when they finish mowing such a large lawn.

What kind of fuel does a petrol lawnmower use?

We recommend using petrol with a minimum octane level of 87. Lawn mowing engines aren’t as fine-tuned as car engines and they can use low octane gas. However, each engine comes with its recommendations and you should check before putting petrol in your lawnmower for the first time.

Ideally, you want to use genuine petrol from a petrol station. You want to stay clear of dubious sources of petrol which can come with all types of impurities. These impurities can be detrimental to your lawnmower in time as they can clog it up and you might lose more on the long-term with low-quality fuel.

Are Stihl petrol lawnmowers any good?

High-quality stroke engine Stihl and Viking are new to the mower offers market. They make good petrol lawnmowers with rear rollers and a 2-year warranty so they can be trustworthy. Stihl is also a company that makes hassle-free lawn mower parts easily available in case you need to replace them in the future.
