Mower Type and Power
This lawn mower inch (46 cm) petrol lawn mower is built around petrol power and a wide cutting deck, which makes it suitable for lawns where a self-propelled mower can reduce pushing effort. It uses a 139cc petrol engine, and this engine size indicates it is intended for regular mowing rather than only light trimming. The mower is electric-start, so ignition is handled by an electric system while the petrol engine runs normally. It is self-propelled, meaning forward motion depends on the drive system rather than user pushing alone. Cutting heights are adjustable.
Cutting Width and Deck
The 46 cm cutting deck on the Hyundai petrol mower is designed to cover a wider strip in each pass, which can help when mowing medium-sized lawns. A broader deck can reduce the number of passes needed on straight runs, saving time. The mower also offers 6 adjustable cutting heights, so the deck can be matched to different grass lengths. On thicker patches, a broader deck may leave uneven results if the ground is not level, so overlapping passes can be necessary. Overall, the deck width suits routine trimming, but the quality of results depends on how level the ground is.
Lawn Size and Collection
How well the lawn mower petrol lawnmower fits a yard comes down to two things: the 46cm cutting width and how the grass is collected. With a 46cm deck, it suits medium lawns rather than very large estates, because mowing passes still add time as the area grows. Collection relies on a large 70l grass bag, so mowing sessions can run longer before emptying. Dense, wet grass may fill the bag faster, and clippings will need removal if the bag capacity is reached. For best results, it should be used in steady straight lines, overlapping slightly to avoid missed strips.
Ease of Use and Storage
Using the Hyundai/46cm 139cc petrol lawnmower is fairly straightforward because it is an electric-start, self-propelled petrol mower designed for practical day-to-day cutting, with foldable handles and adjustable cutting heights. The user can set one of 6 cutting heights before mowing, then relies on self-propulsion to keep pace across the 46cm cutting width. After use, it is easier to store due to the foldable handles, which reduce the mower's footprint. The large 70l grass bag supports uninterrupted collection, but it may still require frequent emptying on long sessions.
Who Is This Lawn Mower For?
The lawn mower/46cm 139cc petrol lawnmower is aimed at homeowners who want a practical, petrol-powered mower with a 46cm cutting width for efficient mowing across typical garden lawns, while keeping everyday use straightforward. The title specifies electric start, making it a good option for those who prefer an electric-start-style petrol mower. With 6 adjustable cutting heights, it suits lawns that vary in grass length across seasons or need different settings for uneven growth. A 70L grass bag is designed for fewer stops to empty, particularly on medium-sized areas. It may be less suitable for very small yards where storage and frequent manoeuvring are more important.
Where to Buy in the UK
Where to buy matters for the Hyundai 18"/46cm 139cc electric-start self-propelled petrol lawnmower, because availability can vary by retailer and stock status. In the UK, buyers should first check major outdoor power equipment stockists that list The Hyundai petrol models, then compare online listings and confirm the description includes electric-start, 6 adjustable cutting heights, and foldable handles, along with the 46cm cutting width and 70L grass bag. If the item is temporarily out of stock, buyers should verify the delivery estimate shown by the retailer, and check that the product page states the warranty terms.
Frequently Asked Questions
Is the lawn mower worth it?
For keeping a lawn tidy with the least hassle, the Hyundai (a petrol mower) does the job with a 46cm cutting width. Whether it suits you comes down to your lawn size, terrain and how much effort you want to put in. Check the current Amazon UK price, as mowers are often discounted in season.
What type of mower is the lawn mower?
This lawn mower is a petrol mower. Petrol mowers are powerful and cordless for big or rough lawns; cordless battery mowers are quiet and low-maintenance for most gardens; corded electric are light and cheap for small lawns; hover mowers glide for edges and slopes; manual push mowers are eco and silent for tiny lawns. Choose the type for your lawn size and terrain.
What is the cutting width of the Hyundai?
The Hyundai 18" has a 46cm cutting width. A wider deck cuts more grass per pass so you finish faster - better for bigger lawns; a narrower deck is lighter and more manoeuvrable around borders and obstacles. Match the width to your lawn size and how tight the spaces are.
How powerful is the lawn mower?
This lawn mower runs on a 139cc petrol engine. Petrol engines give strong, sustained cutting power for long grass and large lawns.
Is the Hyundai self-propelled?
Yes - the lawn mower is self-propelled, so it drives itself forward and you simply steer. That's a real help on larger lawns or any slope, saving you pushing the full weight of the mower. On small flat lawns a push mower is fine and lighter.
Does the Hyundai collect or mulch the grass?
The lawn mower collects clippings into a grass box as you mow, so you get a clean finish and simply empty it when full. Check the grass box capacity against your lawn size to avoid frequent stops.
Is the Hyundai 18" easy to store?
Storage depends on the design - many electric and cordless mowers fold or stand upright to save space, while petrol and ride-on mowers need more room. This lawn mower is a typical example for its type; if space is tight, look for a compact-fold or upright-storage model like Flymo's EasiStore range.
