Mower Type and Power
This lawn mower petrol lawnmower uses a 139cc 4-stroke petrol engine. It is designed to mow a 42cm path in each pass, and being a petrol model it relies on fuel and recoil pull starting rather than mains power, making it better suited to gardens where extension leads are inconvenient. The 139cc 4-stroke format typically supports steadier running for longer sessions, while it also requires routine attention such as keeping the engine well maintained and storing fuel safely. It is self-propelled to reduce pushing effort once moving, although start-up still involves manual pulling.
Cutting Width and Deck
Cutting width and deck size matter because they influence how much lawn gets covered in each pass and how easy the mower feels around obstacles. The Hyundai uses a 42 cm cutting width, so it covers roughly that strip each time, which can reduce passes on open lawns. Its deck supports mowing over uneven ground, but clearance near beds, steps, and fence lines will still require careful steering. With five cutting heights, the deck can be set to suit different grass lengths, helping avoid scalping. For larger, dense patches, the 42 cm cutting width may require more overlapping passes.
Lawn Size and Collection
For lawns that require regular trimming rather than deep renovation, the lawn mower (42 cm) petrol self-propelled lawnmower is a practical fit because its 42 cm cutting width covers more ground per pass, helping reduce the time spent mowing open sections. For larger spaces, this wider pass can reduce how often the mower needs repositioning, although lawn density and grass growth still affect the mowing pace. The 45 litre grass collector is designed for collecting cuttings, so mowing runs can be planned around when the collector needs emptying. With five cutting heights, the mower can be adjusted for different lawn conditions, although tall grass may need more passes to achieve an even finish.
Ease of Use and Storage
With a 42 cm cutting width and foldable handles, the Hyundai (42 cm) petrol self-propelled lawnmower is designed for easier handling during everyday mowing, while aiming to make storage more manageable. The foldable handles reduce the space it takes up in a shed or garage, rather than leaving it as a bulky shape. A removable 45 L grass collector helps with cleaning, as it can be taken off to empty. The recoil pull start is straightforward but still involves manual effort, particularly after longer periods of storage. It also has five cutting height settings, so the height needs to be set before mowing.

Frequently Asked Questions
Is the Hyundai worth it?
For keeping a lawn tidy with the least hassle, the lawn mower (a petrol mower) does the job with a 42cm 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 Hyundai?
The 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 this lawn mower?
The Hyundai has a 42cm 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 Hyundai 17-inch?
The lawn mower runs on a 139cc petrol engine. Petrol engines give strong, sustained cutting power for long grass and large lawns.
Is this lawn mower self-propelled?
Yes - the Hyundai 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 lawn mower collect or mulch the grass?
The Hyundai 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 lawn mower 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. The Hyundai 17-inch 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.
