Hyundai Self Propelled Electric Start Petrol Lawn Mower review

Specifications

  • Lawn Size: Large
  • Engine: 196cc
  • Cutting Width: 51cm
  • Cutting Height Range: 25mm-75mm
  • Collection Bag: 70l
  • Weight: 43.8kg
  • Drive System: Self propelled

Self-propelled mowers are worth their weight in gold if you’re trying to tackle a sloped, or particularly large, garden area.

With rear-wheel drive and 4 speed settings, the Hyundai Self Propelled Electric Start Mower takes most of the effort out of mowing. In fact, it turns cutting the lawn into an almost leisurely experience – it even has cup holders built in to the handle!

Generally, when it comes to starting petrol lawn mowers, it can be a challenge, but this Hyundai model makes it a stress-free task: the electric-start function results in a reliable start every time, and there’s no need to struggle with the jarring yank of a pull cord.

The 51 cm cutting width may be too big for smaller gardens, but if you’re working with a larger space it can really cut down (!) on cutting time. Plus, you get a lot of scope when it comes to cutting height, able to adjust the blades from 25 mm to 75 mm. Whilst this powerful 196 cc motor doesn’t often struggle, having the option to change the cutting height makes it possible to cut even dense grass, passing over it first on a higher setting, and then a lower one.

Able to be changed between rear discharge, grass collection, and mulching, the mower comes with a discharge chute, 70 L grass collector, and mulching plug, so it’s easy to switch between options. The 70 L grass collector has a decent capacity, although it’s may be a little small in proportion to the mower. It does also feature a grass-level indicator that makes it clear when it’s close to full.

Hyundai have also included a relatively novel cleaning arrangement: you can attach a hose to the deck-cleaning connection on the mower in order to rinse the blades and purge them of debris.

Whilst this is a powerful and responsive mower, it does have a few downsides. Weighing 43.8kg, this is a sizeable and heavy machine. If you need to move it a fair distance to get from your shed to lawn, which will need to be done without the help of the mower’s self-propel motor, you may find it too difficult. Furthermore, it’s really best suited to large, open gardens because manoeuvring it around central flowerbeds, or narrow pathways, can also be hard to do.

Pros

  • Quiet motor which doesn't make as much noise as a 2-stroke engine mower.
  • Electric starter means no cord pulling to get it started - perfect for anyone who finds the pulling motion challenging.
  • Starts easily first time.
  • Wide cutting width means it's relatively quick to cut several acres of grass.
  • Hyundai have created an informative instructional video to help with assembly.

Cons

  • May be too large for a smaller/medium sized garden.
  • Quite heavy, especially when collector is full of wet grass, making manoeuvrability difficult.
  • The instruction manual is lacking and not very informative.
  • Can be difficult for some people to move from shed to mowing area due to weight.
  • May be best suited to a garden without a lot of narrow pathways and flower beds to navigate.

Murray EQ700x Self Propelled Rotary Petrol Lawn Mower review

Specifications

  • Lawn Size: Large
  • Engine: 161cc
  • Cutting Width: 53cm
  • Cutting Height Range: 28mm-92mm
  • Collection Bag: 70l
  • Weight: 37kg
  • Drive System: Self Propelled

If you’re looking for something that will be suitable for larger gardens, this Murray EQ700x Self Propelled Petrol Lawn Mower combines a powerful Briggs & Stratton 161 cc engine with a generous 51 cm cutting width and a 70 L grass box. Altogether, this makes for a sizeable machine that covers large areas easily without wasting time.

Briggs & Stratton engines are renowned for their reliability, and due to the self-propelled nature of this Murray Petrol Lawn Mower, this machine cuts neatly and evenly, even on uneven lawns and small slopes, without requiring too much effort from you.

The decent capacity of the 70 L grass box reduces the number of times it needs emptying whilst cutting the lawn, whilst the 51 cm cutting width keeps passes to a minimum. As a result, jobs take a significantly shorter time to complete.

Plus, you can choose whether to collect the grass, use the mulching plus to fertilize your lawn, or simply discharge the cuttings as you mow to avoid emptying the grass box at all.

When it comes to cutting height, this mower allows you to choose from a range of 28 – 92 mm. Whilst there are many models that can cut lower than 28 mm, the maximum cutting height of 92 mm is bigger than most, making it easier to tackle longer grass.

Of course, due to its large size, this lawnmower is unlikely to be suitable for smaller gardens – in general it’s just too wide to be practical in tighter spaces. However, if you’re working in a large area, this is an excellent model for getting the job done quickly even if the lawn is somewhat sloped.

Pros

  • Quick and easy to assemble - you just need to clip the handle, tighten bolts, attach top half and connect two cables.
  • It feels well balanced across all wheels helping it be easily controlled.
  • Self-propelled speed is quite fast making it suitable for larger lawns.
  • Relatively low fuel consumption.
  • Hose attachment makes it easy to clean the deck.

Cons

  • The lowest cutting height may still be a bit long for some gardens.
  • The handles are not very ergonomic and may start to be uncomfortable after 30 mins or so.
  • Due to its large size, manoeuvrability in narrow spaces is difficult.
  • Putting the handles down is quite a long process so it's not very practical to do each time for storage.
  • Requires engine oil before starting which does not come included.

Hyundai Lightweight Push Rotary Petrol Lawnmower review

Specifications

  • Lawn Size: Small
  • Engine: 79cc
  • Cutting Width: 40cm
  • Cutting Height Range: 25mm-75mm
  • Collection Bag: 40l
  • Weight: 19kg
  • Drive System: Push

For those who love the idea of a Hyundai mower, but are put off by the 44 kg weight of the Self Propelled Electric Start model, there’s another option available: the Hyundai Lightweight Push Rotary Petrol Lawnmower. It boasts a powerful 79 cc 4 stroke engine, yet weighs 19 kg, offering the reliability and quality of a Hyundai mower in a lightweight, more compact design.

In fact, this is one of the lightest petrol lawnmowers on the market full stop, making it more accessible to a range of gardeners regardless of physical strength.

Measuring just 100 x 51 x 134 cm, it’s also one of the best petrol lawn mowers for those who are short on storage space; the handles can also be collapsed down, and the grass bag folded up. Regardless of available space, it’s certainly never a bad idea to buy tools that won’t use up too much room, and this one can even fit in storage boxes.

Despite its compact design, this Hyundai Lightweight Lawnmower still has a 40 cm cutting width. This is the smallest size featured on this list, but it’s still well suited to small/medium size lawns, negotiating spaces well whilst not taking forever to complete the job.

With 7 cutting heights to choose from, ranging from 25 mm to 75 mm, it’s a useful and versatile machine, able to collect the clippings or dispel them onto the lawn as you prefer.

As you can imagine, such a lightweight mower has to compromise somewhere to achieve its manageable construction, so it’s worth noting that the body of the Hyundai Lightweight Lawnmower is made from blue plastic, not metal as may be expected.

Pros

  • Easy to assemble, only requiring you to attach wheels, handles, and put in oil and petrol.
  • Works well even on wet grass.
  • Lever is easy to use to change between cutting heights.
  • Can cut in about half the time of some electric mowers.
  • 4-stroke engine oil comes included so you only have to buy petrol separately.

Cons

  • The grass box may require emptying fairly frequently.
  • The instructions provided can be lacking, but there are video tutorials online to help.
  • The outer body is made from plastic which may appear slightly lower quality than if it was metal.
  • Some find it struggles with longer grass over 6 cm.

Mountfield Petrol Rotary Lawn Mower review

Specifications

  • Lawn Size: Medium
  • Engine: 123cc
  • Cutting Width: 46cm
  • Cutting Height Range: 22mm-65mm
  • Collection Bag: 60l
  • Weight: 27kg
  • Drive System: Push

For creating a close cut, the Mountfield Petrol Rotary Lawn Mower has some of the lowest cutting heights featured on this list. Plus, with a 46 cm cutting width it’s big enough to make short work of medium-sized gardens, whilst only weighing 27 kg.

With 6 height positions to choose from, ranging from 22 – 65 mm you can create the neat finish you want whilst also tackling thicker patches on the lawn. Additionally, the 46 cm cutting width is a practical size for acting as ‘the best of both worlds’. It’s wide enough to reasonably efficiently tackle larger gardens, but still thin enough to negotiate narrower spaces. That said, if you have a lot of tighter gaps in your garden, it’s worth checking whether 46 cm will be appropriate.

A simple lever allows for changing between cutting heights, and there’s also a mulching plug for those who prefer to recycle the clippings back into the lawn. Otherwise, grass clippings can be collected in the 60 L grass box, and thrown into compost heaps or green recycling.

Whilst the 123 cc Mountfield engine works powerfully to create a clean cut, the mower is not self-propelled so this is something to consider if your garden is sloped or very large. It does also rely on a pull-start mechanism, with no electric-start capacity; this is generally quite reliable, but may not be suitable for those with shoulder injuries.

Pros

  • Light enough to lift and move around.
  • Offers good value for money in terms of quality vs. price.
  • Starts relatively reliably on first or second pull.
  • Cuts well on flat and level surface.
  • The cutting height is easy to adjust by simply moving the lever.

Cons

  • Let down by poor assembly instructions in the user manual are not very clear.
  • Some find it difficult to assemble the grass box as the connectors can be tight fitting.
  • The oil cap is somewhat awkwardly positioned - using a funnel makes it easier to fill.
  • May be too heavy to use on a sloped garden because of its manual-push design.

Sprint Self Propelled Petrol Lawn Mower review

Specifications

  • Lawn Size: Large
  • Engine: 161cc
  • Cutting Width: 53cm
  • Cutting Height Range: 28mm-92mm
  • Collection Bag: 70l
  • Weight: 37kg
  • Drive System: Self propelled

Big lawns can take a long time to mow, and one of the best ways to reduce mowing time is to limit how many passes you need to take up and down the garden.

If freeing up time is a priority, the Sprint Self Propelled Petrol Lawn Mower has the largest cutting width of any mower on this list. Cutting in 53 cm wide strips, with a self-propelled motor and powerful Briggs & Stratton engine, this petrol mower can cover a large area in little time.

Of course, the capacity of the grass collector is equally important when it comes to completing mowing jobs quickly; mower efficiency is all but redundant if you have to stop and empty the clippings every 5 minutes. Fortunately, Sprint have included a large 70 L grass collector, keeping trips to the compost bin at a minimum.

With the option to choose between grass collection, rear discharge, side discharge and mulching, you don’t even have to collect the clippings at all if you don’t want to – they can immediately become fertilizer for the lawn as they’re cut. There are also 6 different cutting heights to choose from (from 28 mm to 92 mm), making it the mower with the widest range of heights on our list.

Now, it does weigh 37 kg, which may be a little heavy for some – especially when removing the mower from storage – but once the self-propel motor is engaged the pushing action is taken care of so it doesn’t wear you out.

Pros

  • The self-propelled speed is well paced without feeling too fast.
  • The handle height and cutting height are quick to change.
  • Creates a really good, even cut.
  • Reliable starting mechanism, starts with first or second pull.
  • Despite its weight, does not feel unwieldly and is easy to control.

Cons

  • The throttle lever for the self-propulsion may not be comfortable to hold for extended periods.
  • Grass collection bag is a bit difficult to assemble.
  • Engine oil does not come included but is required before running.

Sprint Push Petrol Lawn Mower review

Specifications

  • Lawn Size: Small to Medium
  • Engine: 125cc
  • Cutting Width: 40cm
  • Cutting Height Range: 35mm-85mm
  • Collection Bag: 45l
  • Weight: 23.1kg
  • Drive System: Push

Offering a good balance between quality and value, Sprint’s 125 cc Push Petrol Lawn Mower cuts smoothly, working its way through even thick grass. It’s a great choice for those who don’t need an enormous machine, but would still a prefer petrol model to avoid the hassle of a mains or battery-powered mower.

Weighing just over 23 kg, with a 40 cm cutting width, it’s half the weight of some of the mowers featured on this list. Sure, it isn’t self-propelled, so you need to be prepared to put in a bit of work, but it’s much easier to lift and navigate out of storage than heavier models like the Hyundai Electric Start Mower.

Keeping things simple, Sprint’s mower has a 2-in-1 cutting system allowing you to choose between either collecting the clippings, or discharging them as you go. There’s no mulching feature, but it has all the basics that make a decent and powerful mower, whilst keeping weight and price reasonable.

The 6 available cutting positions range from 35-85 mm offering a reasonable variety and making it possible to tackle thicker patches. Whether 35 mm is sufficiently short for your lawn will be up to personal preference, but it’s something you may wish to check.

If you tend to find that the handlebar position of standard mowers isn’t comfortable, this petrol lawn mower allows you to adjust the handlebar to 3 different heights, helping to spare your back. It can also be folded down to make storage that little bit simpler too.

Finally, it’s worth mentioning the lawn mower’s Briggs & Stratton engine – these motors are well known for their quality and it’s always a good sign to see one built in to a petrol mower.

Pros

  • Comfortable to use because handle is adjustable to three different height positions.
  • Light weight and small size makes it easy to manoeuvre around the garden.
  • Well suited to small/medium gardens.
  • Provides a good cut and is able to work through thicker grass.
  • Most customers feel this offers good value for the price.

Cons

  • A little bit of a workout to push through mossy grass/on slopes
  • Engine oil needs to be bought as a separate purchase.
  • Lowest cutting height setting (35 mm) may not be low enough for some.
  • Without a self-propelling motor it can be hard work on large slopes.

Hayter Harrier 41 Rear Roller Petrol Lawnmower review

Specifications

  • Lawn Size: Large
  • Engine: 190cc
  • Cutting Width: 41cm
  • Cutting Height Range: 13mm-60mm
  • Collection Bag: 60l
  • Weight: 37kg
  • Drive System: Self propelled

Who doesn’t love the look of a lawn which has been finished off with perfectly even stripes? This satisfying style can be achieved by using the Hayter Harrier Petrol Rear Roller Lawnmower which allows you to do just that.

As the only mower featured on this list with a specifically-designed component for creating smart stripes, it uses a two-piece polymer roller that won’t mark the turf as it turns.

Cutting in 41 cm strips, it’s easy to take this Hayter Harrier mower right up to the edge of buildings or flowerbeds – the wheels are flush with the edge of the unit so nothing needs to interrupt the neat cutting pattern! This saves time, reducing the necessity to use grass trimmers as well.

Additionally, the 4-stroke Briggs and Stratton engine runs at 190 cc offering strong cutting power, and the self-propelled speed can be easily adjusted. As a result, you can achieve a clean, thorough cut, setting the pace to avoid rushing tougher areas.

Unlike some other models, this Hayter Harrier mower doesn’t include a push-button start; however, the pull cord still offers a reliable starting mechanism that isn’t difficult to get going.

At around 37 kg, without accounting for fuel and collected grass, this is one of the heavier petrol mowers listed. Whilst this doesn’t pose problems once the self-propulsion is activated, it’s worth bearing in mind if you frequently need to transport your lawnmower to another property or allotment.

Pros

  • The ability to connect a hose to the deck makes it much less effort to clean after cutting.
  • Choice of speed settings make it easy no navigate around flowerbeds and get a good cut.
  • Can use slower speed over rough terrain to ensure thorough, even cut.
  • Easy to cut right up to the side of a building or flowerbed because the wheels are in line with the body.
  • The fuel consumption is kept down compared to mowers with 2-stroke engines.

Cons

  • Quite heavy without the power-assist motor, not the easiest to transport and lift in/out of a car.
  • No push-start button, only a pull-cord - although pull cord is quite reliable.

Yard Force Push Rotary Petrol Lawnmower review

Specifications

  • Lawn Size: Small to Medium
  • Engine: 125cc
  • Cutting Width: 41cm
  • Cutting Height Range: 25mm-75mm
  • Collection Bag: 45l
  • Weight: 23.5kg
  • Drive System: Push

If you’re after the reliability of a Briggs & Stratton petrol engine, but would prefer not to burn a hole in your pocket price-wise, this Yard Force Push Rotary Petrol Lawnmower could be just the ticket.

One of the cheapest options featured here, it won’t break the bank, yet doesn’t skimp on power. Providing 125 cc from its trusty Briggs & Stratton engine, it starts easily and, with its 41 cm cutting width, is a great choice for small/medium gardens.

In order to keep the price down, this mower is ‘manual push’ as opposed to self-propelled; however, at 23.5 kg it is still considered manageable. Better suited to level gardens, this may not be the right option if you’re working on sloped terrain.

Even with its low price, this mower doesn’t leave you high and dry when it comes to starting the motor; complete with a specially designed easy-start mechanism, it starts up on the first or second pull after priming.

Offering good power at low speeds, the engine is quiet yet thorough, with a cutting height that can be easily adjusted from 25 mm to 75 mm via a simple lever. In order to keep the overall weight down, the collection bag is 45 L, which will likely require semi-frequent emptying.

The size of the collection bag, combined with the 41 cm cutting width, and manual-push design, make this Yard Force lawnmower best suited to level small/medium gardens. Unless you want a real workout, you’ll probably want to opt for a self-propelled mower, or a lighter model, if you’ve got some slopes to tackle.

Pros

  • Good quality-to-value ratio in terms of power and grass cutting ability.
  • All-round good size for medium gardens; manageable weight with decent width.
  • Handle collapses down easily to save space in storage.
  • More manageable than a wider machine- can negotiate some smaller spaces.
  • Reliable to start thanks to the priming mechanism.

Cons

  • Engine oil is not supplied and is required before use.
  • The size of the grass collecting box is quite small compared to other models of similar size.
  • Not the most suitable for large gardens, or lawns with big slopes.
  • There's no mulching option so it may not be the right model if that is your preferred lawn-fertilization method.

Things to Know Before Buying a Petrol Lawn Mower

Petrol lawn mowers are a popular choice because they are more powerful than electric alternatives and offer a clean, efficient cut.

If you’re thinking about buying a petrol lawn mower, take a look at the following tips to help you make an informed purpose.

Self-Propelled vs Manual Push Petrol Lawn Mowers

A self-propelled lawn mower uses engine power to achieve forward motion – the alternative is you having to push it manually. This is great if you have a large area to mow or uneven lawns and slopes. They also make light work of long grass, grassy tussocks and damp grass. This type of mower requires a larger engine and will be more expensive. They also tend to be heavier and larger.

A push mower will be sufficient if you have a flat, even lawn and rarely need to cut long, overgrown areas. The blades are powered by the petrol engine but the mower is pushed by hand with no help from the motor. These mowers are usually smaller and lighter than self-propelled ones. They offer excellent manoeuvrability in small- to medium-sized gardens; especially useful when cutting around flower beds and features.

Sizing Up Your New Mower

The Cutting Deck

The size of the cutting deck affects how much grass gets cut at a time. In the list above we have seen sizes which range from 40 – 53 cm.

A smaller deck will be suitable for smaller gardens, especially if there are features to mow around. For large gardens, a larger deck will get the job done quicker.

The Grass Collector

Having to keep stopping to empty the clippings bag or box can be a nuisance. If you plan on collecting clippings, choose a mower with a larger collector to cut down on the time spent emptying it.

In the list above we have seen grass collector sizes ranging from 45 L to 70 L. Depending on the size of your lawn, a smaller capacity might be sufficient; however, if you have a larger space it may result overly frequent emptying being required.

The Mower Itself

It’s worth considering where you’re planning to store your mower whilst you’re choosing which model to buy. Some may be much larger than others and you don’t want any unexpected surprises on the day you introduce your beautiful new mower to your shed or garage.

Choosing The Right Starting Mechanism For You

Some mowers have an electric key-start to ensure a reliable start every time. These machines have a rechargeable battery to support this starting mechanism, so you will have to remember to charge this. Most also have a standard pull-start as well, in case you don’t have the battery charged.

Other machines have an automatic choke for reliable starting.

Some models are started by priming and pulling; you will need to press the priming bulb slowly three times to deliver fuel to the carburettor, then pull the starting cord to get the engine going.

Choosing a Model With The Right Cutting Settings

Mowers have a variety of cutting heights usually measured in millimetres. These vary a little and some machines cut lower than others.

You may wish to check how close a shave your mower can give, especially if you want a bowling-green finish to your lawn. Most are adjustable with a simple lever but some are more complicated to use.

Equally, if you’re not so worried about having a lot of height choices, you can find a mower with less height-cutting range and it may work out cheaper.

How to Fuel Your Petrol Lawn Mower

Always use the fuel recommended by the manufacturer and ensure it is fresh. Unleaded petrol goes stale after three months; your mower will be more difficult to start with old fuel.

Check the oil level before every use and top up if necessary.

Cleaning and Mulching Accessories You May Want

Some mowers include additional features such as mulching and/or cleaning accessories.

A mulching accessory will shred the clippings into tiny pieces before discharging them onto your lawn. This helps to fertilise your lawn and maintain moisture. This is an especially good feature if you often cut long grass which would go sodden and brown if left on the lawn without mulching.

If a mower has a hose attachment then cleaning the underside deck becomes much easier. It’s essential to regularly clean your mower if you are going to get many years of use out of your machine. As a result, a mower with a hose attachment makes the process of cleaning much simpler.

How to Maintain & Look After Your New Petrol Mower

A petrol lawn mower will last you may years, however, it may occasionally require repairs. Check that the brand you choose has spare parts available. Take note of the following suggestions to keep your mower in good shape after each use:

  • Check all bolts and screws regularly to make sure they are not loose or missing. Check the wheels to make sure they are not loose or wobbly.
  • Clean the underside of the mower after each use; grass left on the metal parts may damage them. When cleaning and checking the machine deck, always lift the mower up from the front. Turning the mower on its side can allow fuel to flow into the air filter. This will cause difficulty in starting and excessive smoke.
  • Clean the cutting blades of your machine regularly and have them sharpened or replace them as necessary.
  • Clean the grass bag or box. If this becomes clogged it may block air flow or cause poor collection.
  • If your mower is self-propelled check the drive belt regularly. Take off the belt cover, remove grass and debris and check that the drive belt is in good order and properly adjusted.
  • Check the air filter and spark plugs and clean or replace if necessary.
  • Check the oil regularly and fill it up if it’s running low.

A Word on Routine Servicing

Your lawnmower will need regular servicing, much like a petrol car, to keep it working well for years. You can do this yourself or have someone do it for you. Many lawnmowers offer a 3-year guarantee, so this is worth looking out for.

Think About Storage Before You Buy

When purchasing a lawn mower you should think about where you’re going to store it. You don’t want to spend hours choosing the best petrol lawn mower for you only to realise when it arrives that it doesn’t fit in your shed or garage. Some mowers are bigger than others, so look at the specifications when making your purchase.

When winter comes, and it’s time to store your mower, drain the fuel from the tank or run the engine to burn off any remaining fuel.

Always store the mower on a level surface. Do no lean it against a wall or hang it from a hook – this may cause oil to seep to unwanted parts of the engine.

Petrol Lawn Mower FAQs

What petrol should I use in my petrol lawn mower?

You should use clean, fresh, unleaded petrol in your lawn mower. If the fuel is more than three months old it will have gone stale and may not work well.

Check the ethanol content of the fuel. Fuel with an ethanol content of up to 10% is ok to use, but some fuels contain 15% ethanol which should be avoided.

How much petrol does a petrol lawn mower use?

Most standard petrol lawn mowers have a fuel capacity of 1 L.

How quickly this is used up will depend on several factors: how often you use the mower, how powerful it is, and what settings you have it on.

How do I use and maintain my petrol lawn mower to make sure it gives me many years of use?

There are several steps to using and maintaining your lawnmower.

You can routinely service your mower yourself, or take it to a professional to do it for you. Routine servicing includes things like filter and oil changes. If you choose to take your lawn mower to a professional, book your service at the end of the season is a good idea as dealers can be very busy in spring.

You should clean your lawn mower after every use to avoid damage from grass build-up. In particular, make sure that the deck of the mower is clear of debris.
