TOP 7 PETROL LAWN MOWERS FOR LARGE GARDENS REVIEWS
1. Hyundai HYM51SPE Self Propelled Petrol 4-in-1 Lawn Mower
As a self-propelled 4-in-1 petrol lawn mower, the Hyundai HYM51SPE can easily handle lawns up to around 190 square metres, making it ideal for both commercial and domestic spaces. The Hyundai HYM51SPE is a new model of the Hyundai HYM51SP which was our previous best petrol lawn mower for large gardens.
The first difference between the two models is that the newer Hyundai HYM51SPE now has a push-button start along with the traditional recoil pull of the previous model. Secondly, while it’s still a self-propelled mower, the Hyundai HYM51SPE now offers variable speed with a selection of four speeds.
A 5hp four-stroke 173cc petrol engine successfully powers this mower and gives you enough power to ensure a long operating period. To start the mower you can use the traditional recoil pull or you can just push the button for an electric start. However, the battery needs charging for six hours before the mower will start this way.
The self-propelled design of the Hyundai HYM51SPE makes it easy to move around your garden despite its relatively large size. The Hyundai HYM51SPE’s wheel drive is easily engaged with a handlebar lever. This controls the movement of the mower effortlessly across the grass with your guidance as to direction. You can choose from one of four speeds, depending on how fast you want to walk and get the job done. However, it’s not clear what these speeds actually are, so we recommend that you start out slowly and ramp up gradually.
The mower has a generous, wide cutting blade of 58 cm (20 inches) that makes it very suitable for mowing larger areas. In addition, by adjusting the cutting height, you have the choice of six different lengths for your grass as the cutting heights vary from a smooth 2.2cm to a more shaggy 8.5cm. The soft grip of the handle along with the self-propulsion enhances your comfort in this sometimes-tedious chore. The Hyundai HYM51SPE’s grass collection box is larger than usual at 70 litres. There’s a fill indicator so you don’t have to keep checking how full it is.
With four cutting modes, this mower can reach into difficult nooks and crevices as well as mow wide, open lawns. The first cutting mode is the one most usually used – cut the grass and collect the clippings in the attached 70-litre grass collector box. The three remaining cutting modes all return the clippings to the lawn. One mode ejects them spread over the width of the lawnmower; another mode drops them through a chute on the right-hand side of the mower; the final mode converts the clippings to fine particles as mulch and returns them to your lawn to add nutrients.
Other notable features of the Hyundai HYM51SPE are foldable handles and lightweight design. Both of these help in the ease of use, transportation and storage.
- The powerful 5hp 173cc four-stroke petrol engine has ample power for the longest and most demanding lawn cutting tasks.
- Electric push-button for ease of use; now the recoil pull is your backup starting method
- Self-propelled design lets you guide the mower while it goes along effortlessly.
- Four speeds of self-propulsion so you can mow slower or faster depending on your available time and your energy level.
- Four cutting functions/modes are: cut and collect, cut and drop, cut and mulch and cut and side discharge, giving seasonal opportunities for lawn care.
- A six-stage centralised cutting height adjustment gives you a wide range of grass heights from 2.2cm to 8.5cm.
- A larger-than-usual 70L-litre grass collector is easy to handle and the fill indicator lets you know when you have to empty it.
- Large wheels make uneven terrain a snap.
- Quick folding handles make for easy storage and transportation.
- Durable treated-steel cutter deck for efficient and effective grass cutting.
- Ideal for large lawns up to 190 square metres.
- Reliable, durable and affordable mower.
- Comes with a three-year Hyundai warranty for worry-less use.
- Instructions in the box are lacking in detail and confusing, but there’s a YouTube tutorial.
- Grass box lid often falls off or out.
The Hyundai HYM51SPE Petrol Self Propelled 4-in-1 Rotary Lawn mower is a very good lawn mower for large gardens where the wide cutting blade will be most appreciated. The four cutting modes add to the mower’s versatility, as does the variable speed self-propulsion. The centralised six-stage height adjustment gives a full range of grass heights.
Certainly worth considering is the electric start button which starts the mower every time (as long as the battery is charged). The reliable recoil pull cord is now just the backup method. This mower with a 3-year warranty which is another element that makes it become one of the best petrol lawn mowers for large gardens currently available.
If you’re looking for affordability and performance and have a large lawn, we recommend this Hyundai HYM51SPE petrol lawn mower. It earns our “Best Pick” from all of the six mowers reviewed here.
2. Hayter Harrier 48 Pro FS BBC Rear Roller Lawn mower
Introducing the new and improved Hayter Harrier 48 Pro FS BBC Rear Roller Lawn mower that has been tweaked to make your experience EVEN better and a more robust and reliable lawn mower. The model is powered by a 170cc Honda GCVX170 engine that has 11.1Nm torque so have plenty of power behind it to cut at a high speed for better efficiency. The aluminium cutting deck also offers high strength and durability to weight ratio so that you get a piece of equipment that is designed to last and handle the most demanding mowing days.
The lawn mower is equipped with an easy-start recoil system and a generous cutting width of 48cm. This is 8cm smaller than its big brother the HARRIER 56 PRO but 8cm but larger than its baby brother the HARRIER 41 PRO. We think this version of the Harrier Pro range is best because it’s large enough to mower those larger lawns up to 522m² while still not being too large to tackle those smaller lawns of around 261m². with an easy start. The large cutting width allows more surface area to be covered in one go, thus making it perfect for covering large lawns while being nimble enough for smaller lawns.
This model also possesses seven cutting height adjustment settings that range between 13 – 60mm. You can adjust the cutting height with ease with a single lever to meet your different demands depending on the length of the grass.
This lawn mower is self-propelled meaning that the user will not spend too much of their energy moving the machine around but it is single speed so would be nice to see variable speeds in future models. The machine weighs around 46kgs so it certainly a heavy-duty mower and to support this weight it is fitted with quality rubber tires than can handle the demanding jobs of a professional mower moving from job to job.
To ensure that you are comfortable as you work, the lawn mower has adjustable handles to suit your height which is an important feature we think professional lawn mowers need. You will be able to move freely without having to slouch or tip-toe on your feet and it really is a simple but worthwhile feature to have. The lawn mower is also equipped with a split steel back roller to give the lawn those much-needed stripes but it also provides better traction, manoeuvrability and avoids marking the lawn when turning.
All the grass trimmings are collected in the large capacity 70 litre fabric collection bag. The large capacity collector is great as it saves you time wasted rushing to the compost bin or van for emptying.
One new feature this mower does have is a hose connection chamber that permits the cutting deck to be cleaned effectively by attaching a hose pipe which is a great feature to have.
Finally, this single speed lawn mower comes with a 2-year warranty for both commercial and domestic use. These warranties prove that the manufacturer stands behind the quality of his product thus it is reliable.
- Features a powerful and reliable 170cc Honda GCVX170 engine to power the fixed cutting speed.
- Comes with a large cutting width to cover a large surface area in one go but it small enough for smaller lawns while still being wide enough to mow larger lawns with ease.
- Offers an aluminium cutting deck that is not only light but extremely durable.
- It has cutting height adjustment between 13-60mm to get the perfect cut.
- Features durable wheels that permit easy durability.
- Provides the world’s first crank-safe BBC system.
- Comes with a hose connector port to easily clean the cutting deck after work.
- Split roller for creating a striped lawn.
- Features a large capacity collector that saves time and energy used in frequent emptying.
- Offers a 2-year warranty for both domestic and professional use for full peace of mind.
The Hayter Harrier 48 Pro Rear Roller Lawn mower is a good investment simply because of the quality of the features presented and that it’s so reliable and well made. For a professional looking for a quality mower it’s up there with the very best. The lawn mower has a wider cutting width than most other lawn mower making it perfect for large lawns in places like golf-clubs and estates but it also smaller enough for mowing private gardens for general lawn maintenance.
If you have lawn maintenance business, then this self-propelled lawn mower will cut you some slack. You will be able to work without being overly exhausted or uncomfortable. Overall, this is a great product for both professional and domestic settings. It is reliable, powerful, features sharp blades and allows you to cut as close to the lawn edge as you can.
3. Murray EQ500X – 18 Inch/46 cm Self-Propelled Petrol Lawn

4. Hayter R53S 21-inch Self Propelled Electric Start Petrol Lawnmower
The Hayter R53S is a powerful lawnmower ideal for domestic and professional use and is often seen as the ‘Rolls Royce’ of lawnmowers and more good reason. The Hayter mower features an electric engine designed by Briggs and Stratton which uses a ‘’ReadyStart’’ system which activates the mower with the touch of a button to ensure it starts effortlessly. Even though it quite a large mower,, the lawnmower has a compact design which ensures both environmental conservation and ease of use.
For the business end, the Hayter R53S model has a 530mm (21-inch) cutting width which is one of the widest cutting width of any lawnmower on our review for less mowing. It has an adjustable cutting height of 25mm to 114mm which ensures you can set the cutting height to a height to suit your needs. It also comes with a high-quality steel deck which is less likely to get damaged unlike some models with plastic cutting decks.
The machine offers you the choice of three ways to dispose of your grass clippings. It gives you the option to work with the standard rear collection, to recycle the clippings back onto the lawn or to side discharge. Recycling the clicking helps in maintaining a healthy and green lawn. This is achieved through re-circulating the grass clippings into the lawn as a very fine mulch. Thus, as the mulch decomposes and returns to the soil, it gives your grass nutrients.
The machine is also built with a blanking plug that leads from the cutting chamber to the grass box. The cutting chamber has a continuously smooth surface. Thus, the clumps of grass are unable to build up and fall onto the lawn in the wake of the mower.
A unique feature of this machine which we really like is the ‘Sens-a-Speed’ variable speed transmission. It allows the mower to automatically adapt to your walking pace as you mow the lawn so its self propelled but as your own speed. This ensures effective and efficient working using this model. The machine is also lightweight at 43Kg while still being a very robust mower which is able to withstand the daily use by professional gardeners.
- Features a smooth ‘Sens-a-speed’ system which automatically adjusts to your walking pace so you mow at your speed.
- Has a 530mm (21inch) cutting width for quick and effortless operation.
- Includes mulching and returning to the lawn, rear collection, and side discharge capability for improved versatility.
- Features a robust high-quality steel deck for efficient grass cutting.
- Has an electric start engine design for simple start of the mower without having to pull a pull cord.
- Fitted with an adjustable cutting height (25-114mm) for enhanced comfort during application.
- Durable and built with the desire for longevity and practically.
- Easy to use and environmentally friendly.
- Comes with a 3-year manufacturer’s warranty for full peace of mind which hopefully you will never need to use.
The Hayter R53S Mower incorporates impressive features designed for the professional gardener in mind. It has been developed with both the environment and the end-user at the forefront. This makes it perfect for those eco-conscientious gardeners concerned for the environment.
The fact that it has a ‘Sens-a-speed’ system which automatically adjusts to your walking speed makes it easy to use and a stand out feature. The reason we like this feature so much is some self-propelled mowers are either to slow or to fast but this model solves this problem.
We also appreciate its ability to collect, recycle and side discharge grass cuttings. The adjustable cutting height also makes the mower efficient and comfortable during application but we did think that Hayter could make selecting the cutting height a little easier.
For this model, the price is expensive but we think its worth every penny and will never miss a beat. The difficulty in height adjustment will not be a big deal and most people will not change the height once set anyway. Generally, the machine is efficient, well built and designed for environmentally friendly usage and ease of use. Overall a must-have for any professional gardener.
5. Honda Izy HRG 466 SK 4-Wheel Self Propelled Petrol Lawn Mower

The engine is as quiet as possible and has a special auto choke system for easy starting of the mower which ensures it starts the first time. The machine also has a fairly large 55L capacity grass box. It saves your energy and time by minimising your trips to the compost heap
As you would expect this model is self-propelled which makes it ideal for maintaining medium to large gardens including those that are not perfectly level and sloping lawns. Built with high durability, it features a steel cutting deck to ensure it can withstand high workloads and it has a reasonable cutting width of 46cm. The steel deck is specially treated to resist corrosion, rust and UV abrasion for a longer service life to ensure you have it for many years to come which also makes it a great choice for gardeners.
The Honda Izy HRG 466 SK Self Propelled Petrol Lawn Mower is lightweight at 32 Kilograms making it one of the lightest models in our review. A standout feature in this model is the intelligent blade design which is very long-lasting. If the blade hits an obstacle, it will twist rather than break. This saves you money and reduces maintenance requirements, thus making the mower reliable and easier to service.
As with most models, it has folding handlebars which allow for easier transportation and storage. The handles reduce the mower’s package dimensions and size to ensure it’s easy to store when not in use.
- Features an auto-choke system which guarantees easy starting and consistent performance.
- Has folding handlebars for easier storage and transportation.

The Honda Izy HRG 466 SK Self Propelled Petrol Lawn Mower is very reliable and easy to operate mower perfect for both home use and professional gardeners. With the self-drive feature, homeowners who prefer a little more out of their mower will appreciate this model.
We also like Honda’s intelligent blade design. The fact that when the blade hits an obstacle such as a rock it twists instead of breaking off, makes the mower very durable and reliable. This saves your money and gives you much easier work of servicing your lawn mower.
The lack of the mulching system is a little drawback for this model but not a deal-breaker, especially if you collect all your cross-cutting and compost them. Otherwise with other outstanding features incorporated it’s a great mower to consider. The durability of the machine also guarantees real value for investment and the 3-year warranty only further confirms the reliability and quality of this model. This is a great alturnative to our best pick for someone looking for a slightly smaller mower.
6. Mountfield S421R PD 41cm Self Propelled Petrol Rear Roller Lawnmower
The Mountfield S421R PD 41cm Self Propelled Petrol Rear Roller Lawnmower is ideal for making those classic lawn stripes that will be the envy of your neighbours. It has a sturdy, powder-coated steel chassis that ensures the lawnmower delivers excellent finishing and will last for several years if not a lot longer.
The machine comes with a 100cc Mountfield RS 100 OHV 4-stroke engine that’s very easy to start and as it is 4 stroke it means you don’t need to mix petrol and oil together like you so with 2 stroke engines. Its rear roller delivers the forward drive to ensure that the mower cuts right up to border edges and paths with ease, something a lot of petrol mowers fail to do.
With an impressive cutting depth of 41cm/16’’, you can shorten the time you take to cut lawns of about 400m2, now this is probably classed as a medium-sized lawn really but we just had to include it anyway as its probably suitable for many people.
Even more, it allows five different heights of cut, ranging from 2cm to 7cm, and there’s a lever that helps you select whatever height you want for the perfect cut. This ensures that you can choose the most suitable height for the desired finish.
When it comes to grass collection, the Mountfield S421R PD benefits from a large 55-litre collection box, which saves you time by reducing the number of trips to the main compost bin. Furthermore, the grass collector features an indicator that shows you when it needs emptying.
- Comes with a powerful engine that withstands heavy use.
- Rear roller to produce striped lawns. Allows up to 5 cutting heights, which are easily adjusted by a lever.
- Has a large grass collector, which significantly reduces the number of trips to the compost pile.
- Covered by a 5-year warranty.
- Operates at a single speed only.
If you have a relatively medium-sized lawn, the 100cc Mountfield RS 100 OHV 4-stroke mower is a machine you can rely on to create classic immaculate strips.
The machine allows you to cut 5 different heights and you’ll appreciate the lever that lets you choose a desirable height easily. The steel built chassis is durable and this can only be justified by the 5-year warranty that backs this machine.
The lack of a throttle means the mower only operates at a single speed, however, this isn’t a deal-breaker. Overall, great petrol lawnmower with handy moderate features and perfect for medium-sized lawns where one of the larger mowers maybe just that bit too big.
7. Tiger TM5120SP 51cm (20″) Self Propelled Petrol Lawn Mower
The Tiger TM5120SP 51cm (20″) Self Propelled Petrol Lawn Mower is quite distinct from other models in its class. It comes with the ReadyStart Briggs and Stratton 625E Series engine, which we can say it’s the only one of the kind. Built-in the USA, this engine is extremely powerful, exceptionally reliable and remarkably fuel-efficient, and it’s designed to start first time, all the time.
This model features a self-propelled drive system which allows you to offer an easier cut. All you have to do is walk behind the mower and guide it to wherever you want to cut. The model has an all-steel cutting deck that is sure to withstand the knocks and bumps on its tracks. In addition, it features a corrosion-resistant coating and a Tiger Orange finish.
Equipped with a 4-in-1 collection system, the mower brings unmatched flexibility to your cutting experience. If you like a natural finish, then you’ll appreciate the side and rear discharge, whilst those who prefer to mulch their grass cuttings can make use of a supplied mulch plug to return essential nutrients to the lawn. If you like to collect your clippings, you’ll benefit greatly from the 65-litre capacity collection bag.
Also included is a single lever height adjustment system, which allows you to choose a desirable cutting height at any moment. The model offers more than 10 different cutting heights, ranging from 15mm to 70mm. This ensures there’s a choice for every lawn and every season.
- Offers multiple cutting heights, thus you can cut to desired heights depending on the season.
- Has flexible disposing options – you can allow the 4-in-1 system to work for you or collect the clippings in a large bag for emptying later.
- Comes with a reliable and powerful ReadyStart 150cc engine.
- Built with a durable steel deck that would not crack when it comes into contact to stones or unexpected debris.

With its Briggs and Stratton engine, engine speed control and multiple height cutting options, you can always achieve a desirable finish that you can sit back and admire.
We like the 4-in-1 collection system and the option of utilising the large 65L capacity bag.
All in all, this model is a decent affordable pick.

THE BUYERS GUIDE
There are many petrol lawnmowers on the market with all kinds of features. Of course, the more advanced models with top of the range features will be more expensive than standard models.
Keep in mind that almost all petrol lawnmowers are self-propelled, meaning you don’t need to push the machine but rather guide it. In fact, we think that all lawnmowers used on large lawns should be self-propelled for the best user experience so all the mowers that made it onto our review are self-propelled.
At the very least, you can use the following criteria below in choosing a petrol lawnmower:
Petrol lawnmowers engines range from 100cc to 190cc. For tough cutting conditions such as tackling tall, thick, wet grass, always go for a larger engine.
The most basic engine type and the least expensive is the side-valve, which has the valves on the side of the engine block. This engine is slowly being replaced by overhead valves, where the valves are placed in the head of the cylinder, such as the case of a car engine.
The famous Briggs and Stratton engine manufacturer recently introduced another engine variation – the direct-overhead valve. Overhead-valve engine are more expensive and so are the models that incorporate this engine type. However, they offer the benefits of improved fuel consumption, less vibration, reduced emissions and quieter operation.
Front or rear-wheel drive
Front-wheel drive models are for a fact cheaper than rear-wheel drive mowers for a reason. For a front-wheel model to propel forward, the wheels must be firmly established on the ground. The problem comes when you need to lift the front to turn or propel forward through thick grass, debris or other potential obstacles. In such situations, the front-wheel drive becomes useless due to poor traction. Yet, front-wheel drive offers great manoeuvrability on even grounds.
Rear-wheel drive models, however, benefit from better traction because of the added weight at the back. They are always grounded, proving unmatched traction control and manoeuvrability. If your lawn is uneven and needs the extra power to climb steep hills, you’ll be better off with a rear-wheel drive lawnmower.
Recoil or electric start options
Most petrol lawnmowers use the traditional recoil start mechanism to start the engine. You have to manually pull a rope that, in turn, starts the engine manually.
With an electric start, all you need to do is push a button or turn a key to get the engine running. If the idea of pulling a cord to run an engine drives you nuts, pick an electric start option all day long.
Here you can choose from four different mechanisms:
- A bail that allows you to squeeze against the handle.
- A lever that you can push with your thumb.
- A lever that you squeeze against the handle, which mimics the hand brake on a bike.
- A telescoping handle that you push forward to increase speed or release pressure to reduce speed.
The drive control affects how you manoeuvre and it’s important for your comfort. If you need to make a lot of manoeuvring with back and forth movement to cut around plants, choose the lever-operated drive. This will allow you to halt the lawnmower’s drive system and push, pull or move under braches. For mowing wide-open areas, go for a bail-drive control.
Fixed or variable speed
A petrol lawnmower with single speed may be too fast to cut tall or thick grass evenly, or even mulch clippings efficiently. With an adjustable speed setting, you can decide to go faster or slower depending on the conditions of the garden, or your physical conditions as well. There are days when you want to take your time to cut the lawn and other days you’ll feel like racing through your lawn. Models with adjustable speeds come with a hydrostatic drive with cruise control to provide the ultimate luxury.
Most petrol lawnmowers automatically shut off the engine every moment you let go of the bail. Maybe you want to move an object out of the way or pick a weed, the engine turns off, although they are designed that way for safety reasons.
A model with a blade override system won’t do that, but rather keep the engine running safely without the blade spinning. This means you’ll save some time that you may spend turning on the engine again and again, especially with a recoil start model. This kind of operation also increases the life of your engine since you don’t have to stop and start every five minutes.
Your lawn isn’t as straight and flat like a football pitch. You have trees and flowerbed to mow around. Most self-propelled petrol models are designed to steer straight, yet sometimes you need to make turns. The lifting and turning, again and again, makes the wheels wobbly over time. Then one day the metal bolt sheers and the wheels fall off.
Intelligent manufacturers are now installing swivel front wheels, which are designed to offer better manoeuvrability whilst keeping the wheels grounded on the mower.
Lawnmowers handle grass cuttings differently. Some can cut, mulch, discharge the clippings out of the deck, or collect the clippings in a bag. Other models can do just two of these functions, either mulch and bag, or mulch and side-discharge. A 3-function mower will at least offer optimal versatility.
Having looked at the features above, allow us to introduce you to our petrol lawn mower reviews where we further discuss the best lawnmower for large gardens.
How do you maintain a petrol lawn mower?
Your petrol lawn mower maintenance plan should include after each use, annually and winter maintenance. Here’s a checklist of what to do:
After each use:
- Clean the mower after each use.
- Fill your petrol can.
- Brush off the mower blades (empty the petrol tank before turning the mower over).
- Sharpen blades regularly.
- Change the spark plug.
- Clean or replace your air filter.
- Change the oil.
- Thoroughly clean the underside of the mower with the garden hose (some mowers have an attachment to connect to the hose).
- Thoroughly clean the mower and dry it.
- Empty the petrol tank.
- Check everything is in working order.
- Place the mower in a warm, dry place.
How big a lawn mower do I need?
“Big” can mean various things with respect to lawn mowers. We’ll look at three elements – power, cutting blade width and physical size
The first question is whether you want a petrol, electric or cordless lawn mower. Each type of lawn mower has its own power range. For example, electric – from 20 volts to about 80 volts, petrol from 3bhp to about 5.5bhp, and cordless (battery) from 300 watts to 1500 watts.
The power you choose depends in part on the size of your lawn and how fast you want to do the grass cutting chores.
Cutting blade width
For small lawns less than 50 square metres, a 30cm – 34 cm blade is suitable.
For medium lawns of 50 – 150 square metres, you need a 35cm to 40 cm blade.
For large lawns of greater than 150 square metres, the blade should be larger than 40cm.
Generally the larger the lawn mower the more heavy it is. However, if you purchase a self-propelling petrol lawn mower, it’ll just move along with you only needing to guide it. This feature reduces the problems of moving a heavy mower. Many lawn mowers also have ergonomic features such as an adjustable handlebar which make operating them, whatever their size, more comfortable. Your personal and lawn circumstances will dictate what size mower is right for you.
People with large lawns who want a petrol lawn mower are spoiled for choice with our Best Pick, the Hyundai HYM51SPE, and our Runner-up, the Murray EQ500X – 18 Inch/46 cm Self-Propelled Petrol Lawn Mower. These lawn mowers are a similar size and share many features such as cutting blade size, self-propulsion and the 4-in-1 cutting mode. The Hyundai HYM51SPE edged out Murray EQ500X with the addition of two new features over its previous model: the variable speed self-propulsion and the electric start button. These new features contribute to the ease of use and comfort of cutting grass with the Hyundai HYM51SPE. However, both our Best Pick and our Runner-up will do an excellent job mowing your large lawn.
