Nothing beats petrol lawnmowers when it comes to mowing large gardens. These mowers are very powerful and can be out there for as long as you as you need, unlike cordless mowers that run out of battery power at some point or corded models that are limited by there power cord. Another thing, petrol mowers feature wide cutting widths, allowing you to cover distances in almost half the time of other types of mowers. And as the name suggests, petrol mowers use fuel to operate and that’s something you can easily get from any petrol station. Dealing with petrol also means regular engine maintenance is a must so as to keep it in top condition but this is fairly straight forward and is much easier than most people think.
However, the big question is, which are the best petrol lawnmowers for large gardens? Truth is, there is a lot to think about before making any conclusion as to which model stands out of the crowd. You have to look at the start – whether electric or recoil start, engine type – 2 stoke or 4 stroke, constant or variable speed, cutting width, grass collection box size, and many more factors.
We did our homework on the same and picked six petrol lawnmowers. We put a lot of research into them all and concluded that the top lawnmower for large gardens for most people is the Hyundai HYM510SPE 173cc Self Propelled Petrol Lawn Mower.
Launched in 2018 as Hyundai’s flagship petrol mower, it houses a 173cc 4-stroke engine with a lower than average fuel consumption. It then combines a recoil start with an electric start for ease of use, while it has a rear wheel drive for effortless mowing. The model is fully adjustable when it comes to mowing speed and cutting heights, as well as being versatile in cutting. We don’t think you can get anything better at its price point which helped it win our ‘Best Pick’ spot.
There is so much to love about this model. Its 51cm cutting width is the first indicator the mower is intended for large lawns. You get an easy electric start for instant starting as well as the standard recoil start back up. The 70 litre grass collector is the biggest compared to other models, while you’ll love the cutting options in the form of cut and collect, side discharge, rear discharge, and mulch. Quick release folding handles make it easy to store and transport, and the machine has a 3-year warranty for peace of mind. This truly is a beast of a machine with all the fancy features while still be affordable in mower terms.
Mini Buyers Guide
As mentioned earlier, there are factors to consider when comparing different options.
The first thing should be the size of your garden. Ideally, the larger it is, the more work the machine has to do to complete the work. Since you don’t want to spend all day mowing, look for one with a decent amount of power to finish the job much quicker matched with a good wide cutting width and large collection box.
Self-propulsion is another thing. You see with a small patch, there is no big deal pushing a heavy mower around. But that’s not welcomed when you have acres of ground to cover, so consider a self-propelled mower and all you’ll have to do is guide it, even better look for multiple speed setting so that it cuts at your walking pace.
Keep in mind that a machine with a wider cutting width will help complete the job quicker than that with a narrower cutting width, obvious but something many people overlook.
The size of the grass box will determine how often you’ll need to empty it out, while the larger it is, the heavier the mower will get. Also look for mulching options and the type of discharge if you don’t need to collect.
Fuel consumption has to be in your mind as you don’t want a guzzler in your garden. A rear roller will leave neat striped finishes on the lawn and the handlebar has to feel comfortable specially when mowing for longer periods of time. Folding handles are highly appreciated when it comes to storage in the garden shed or transporting the mover in the back of a van but this is now pretty standard in nearly all mowers but some are more compact than others.
How about you take time reading the in-depth buyers guide after the product reviews below?
Now this one suits every homeowner with a relatively large garden. Not only because of the affordable price point but also because it’s powered by a reliable engine from Briggs & Stratton. It has a 2-in-1 system that allows either rear discharge or collect the clippings which keeps it simple, while users can greatly benefit from 6 height of cut settings. Its ergonomic handle bar is adjustable in three height settings and it can fold back in for compact storage. These kind of features suit anyone that’s looking for an easy to use petrol lawn mower with all the essential features, yet powerful enough to handle big and small tasks alike.

Our best pick the Hyundai HYM510SPE 173cc Self Propelled Lawn Mower is big and powerful, making it a great pick for anyone with a large lawn to cut. This model came out in 2018 so is relatively new and is not only the flagship of Hyundai’s range of self-propelled lawnmowers, it’s also a favourite for many commercial gardeners and our favourite pick, a good match of performance, features and affordability. Something else that stands out about this mower is that it has multiple speeds when self propelled so you can match your own walking pace while most other self propelled mowers have just one single speed so this is a nice feature to have as we have found some self propelled models to be a little slower than we might prefer so its good to have a choice of speeds.
To begin with, this petrol lawnmower has an electric push button start for quick starting, this is usually only found on the most expensive mowers. And if this option ever fails, there is a backup recoil start to ensure you’ll never get stuck. This combination is a major selling point, unlike many other models that feature a recoil start only some of which can take a few pulls before the engine fires up.
When it comes to discarding the grass clippings, you have four options which is another reason this was chosen as our best pick; Collect, Side Discharge, Rear Discharge and Mulch. It’s totally up to you to decide how to want to deal with the grass clippings but we recommend collecting and mulching every now and again to help feed the lawn and add essential nutrients back into the lawn. Should you wish to collect, the mowers extra-large 70 litre collection bag will ensure that you don’t have to spend to much time emptying the collection box but rather spend more time cutting grass.
What’s more? There’s a handy lever that allows you choose a desired cutting height which is easy to use, with the shortest being 25mm for a really close cut and the tallest 75mm which can be handy for mowing longer grass in stages.
In terms of construction, this one is well-built and includes durable parts for total reliability. The OHV 4-stroke engine has low emissions, meaning your garden will not be surrounded with harmful or unpleasant fumes plus the engine is also low maintenance and economical in operation. Something else we really like about 4 stroke engines as apposed to 2 stroke is there is not petrol and oil to mix as they are put in separate meaning you mainly just need to refuel with petrol when needed.
Another plus about this Hyundai mower is you won’t need any tools at all to assemble this machine, meaning you can get to work as soon as possible, simply add oil (you need need to purchase separately) and fill with petrol. It’s also built with soft grip handles that are comfortable in hand, while they are designed to fold down for space-saving storage and easy transportation. There’s even a bottle holder to carry a drink on the go which is yet another simple but great feature that some will find useful. Safety is another thing that has been looked into, with a clever operator presence control (OPC) lever available to prevent the engine from running when the handle is released.
Another thing you’ll notice is the rear wheels being larger than the front ones. This enhances smooth manoeuvring as well as traction, which is something you want especially when cutting around obstacles such as trees.
While cleaning the exterior of a lawnmower is pretty straightforward, the underside has always been something been a manual thing to do. However, this Hyundai model is different and has also though about this. It has a wash port hose connector that allows you to attach a garden hose using a and run the mower for self-cleaning.
Overall, the Hyundai HYM510SPE 173cc Self Propelled Lawn Mower is perfect for those looking for a high quality mower with all the fancy features of more expensive mowers from brands such as Hayter but at a more realistic price. Don’t forget this model comes with a 3-year warranty for full peace of mind and confidence on the lawn. Hands down our top pick.

The deck has six height of cut adjustments between 28mm and 92mm that can be set by two levers which is fairly easy to do. Even the handle bar is adjustable in 3 heights for comfortable mowing depending on the height of the user which is a nice feature to have, especially for both smaller and taller gardeners. It also folds down to reduce precious space in the shed as do most mowers.
Both its front and rear wheels measure 18cm in diameter, making them a good size for smooth mowing over thick grass.

Murray have a quick set up video on their website to help you get started with this machine which is handy but its pretty straight forward but may help if you have never had a petrol mower before. Now this model comes with a 2-year warranty should you find something wrong with the product but hopefully this will never be needed.
Overall, this a powerful and versatile lawnmower that has all the basic features with a few nice added features such as self propulsion and adjustable height handles.

A great affordable mower for those with a large garden and don’t need all the fancy features of our Best Pick.

A petrol lawnmower is a good investment if you have a large garden. A decent one will last for many years to come if well maintained. Below we expound on the key things to consider before making a purchase.
How to choose the best lawnmower for large gardens
Engine type and capacity
The most basic type of engine is the side-valve with valves on the side of the block, and it also happens to be the cheapest. Then there is the engine with overhead valves, located at the top of the cylinder like the one you see in a car engine.
The third type is the direct overhead-valve, which is common with Briggs & Stratton engines. This engine is quite expensive and so is any model that has it. However, it has the benefits of economical fuel consumption, very little to no emissions, quieter operation and low vibration.
When it comes to capacity, petrol engines for lawnmowers range from 100cc to 200cc. A larger capacity is good for when dealing with long, thick, or wet grass.
Then there’s a choice to make between a 2-stroke and 4-stroke engine. Go for a 2-stroke engine if you want a lightweight and cheaper option. If you have a sloped lawn, also look no further than a 2-stroke engine because they cope well with such terrain.
On the other hand, a 4-stroke engine is a great option if you want more power, easy starting and something that’s low maintenance. Because of its power, this engine is the best for mowing through long, thick, wet grass. While a 2-stroke engine can be stubborn to start in the cold, a 4-stroke starts first time no matter the weather.
Regarding maintenance, a 2-stroke engine runs on a mixture of oil and petrol, meaning you will need to mix correctly. Its counterpart, however, is filled with petrol and oil separately, thus minimal chances of error.
Generally, the larger the cutting width, the wider the area you will cut with every pass. For instance, a cutting width of 50cm is about 25% larger than a cutting width of 40cm. This means if both are put to work, the mower with 50cm cutting width will take 25% less time to mow a given area compared to the smaller width.
Cutting height adjustment
The best lawnmowers offer multiple cutting heights. Many a times you will hear people saying that the mower didn’t cut low or high enough. But as you have seen from the products in our list, you can get up to seven height cuttings from as low as 20mm to 90mm. Just pick one that you think will give the cut you like. Also, chose a machine that cuts a bit higher if your lawn is bumpy.
This a must-have feature for lawnmowers that cut large gardens. The wheels draw power from the engine for them to propel, meaning you don’t need to push the mower but just guide it. However, you’ll need to check the speed of the machine and whether it can be adjusted or not. The Hayter Harrier 41 Autodrive lawnmower is a good examples of models with variable speed settings.
Obviously, your lawn is not as straight and flat as a football pitch. There are probably trees and flower beds that you’ll need to carefully manoeuvre around. Some self-propelled mowers are designed to steer straight, meaning you’ll need to lift the up in a way so as to make turns. Others have swivel front wheels that simply turn to any direction without having you having to break sweat.
The word here is ergonomic. Such a handle is designed to put your arms in a natural position, thus less tiring to use. A soft grip also implies no blisters when guiding the mower by holding the handles for long periods of time. Some handles such as the one on the Murray EQ300 are height adjustable too, allowing users to select their most comfortable working height.
You will want to pick a more compact mower if there is not plenty of storage. Go for one that allows the handles to fold down so that it can sneak nicely into a garden shed and still allow other things to be kept above it.
Recoil vs electric start
Recoil starts require you to manually pull a rope in order to start the engine, though many such modern mechanisms are easier and more dependable than they used to be.
If you don’t want to use any effort at all in starting the machine, go for an electric start. All you have to do is push a button to get rolling.
Some models integrate an OPC (Operator Presence Control) feature, which shuts the engine every time you let go of the handle. Perhaps you want to stop and get an unwanted object out of the way, the machine turns off until you get back in control.
Others have blade override systems, which won’t power off the engine but rather stop the blade from spinning while the engine runs safely. This one is a good feature for a recoil start engine as it saves the hassle of having to manually start it again and again.
Cutting and disposal system
Consider how you want to deal with grass clippings. Some models have up to four options including cut, collect, side or rear discharge and mulch. Other have two of these functions while some offer three options. A 3-in-1 lawnmower will offer optimal versatility in this case.
At least every petrol mower we found had a warranty, whether just 1 year or 5 years. It’s good to say no matter the machine you buy, it will be well covered. The Hayter Harrier 41 model stands out in this department.
Other nice additions
Every mower is blessed differently and that’s where you may want to evaluate those bonus features and choose the ones you like.
One of them is a rear roller, which is something to think about if you want those elegant and neat stripes on your lawn.
Consider the noise level of the machine if you don’t want to annoy your neighbours every time you mow.
You also have to make sure that the grass bag is of a decent size, at least 50L capacity. Our best pick the Hyundai HYM510SPE boasts a massive 70L grass box – a great pick if a large capacity is important to you.
Well, that wraps this buyers guide and hopefully you have learnt something new.
