Hyundai 46cm / 18" Petrol Lawnmower Review UK 2026
Quick verdict
Score: 7.4/10
Best for: Keeping your lawn tidy to suit its size and terrain
Not for: A lawn much bigger or rougher than this mower is built for
Bottom line: A capable lawn mower (petrol mower, 46cm cutting width) for a well-kept lawn.
Despite the Hyundai 46cm (18") petrol lawnmower being designed for typical UK garden mowing, it is best assessed against the features highlighted in its title. The 46cm cutting width suits mid-sized lawns, while the mulching approach re-cuts grass back into the lawn. The "Easy Start" claim suggests easier starting, and the self-propelled wording indicates reduced pushing effort.

Mower Type and Power
This lawn mower / 18-inch petrol lawnmower is self-propelled, with forward drive built into the machine while the operator mainly controls direction and speed. It uses a 3.5HP 4-stroke petrol engine, so power is supplied by fuel rather than batteries. This self-propelled petrol design is typically better suited to regular garden areas than light-touch use, and it can be easier to handle for longer sessions and when mowing on slopes compared with a basic push model. Starting is described as "easy start".
Cutting Width and Deck
With a 46 cm (18 inch) cutting width, the Hyundai petrol lawn mower covers a fairly wide swath with each pass, which can help reduce the number of times it needs to move across the lawn. The deck is designed to keep cutting consistent as the blade works through grass, which helps on uneven patches where height can vary. For best results, it is typically used with overlapping passes to avoid missed strips. If grass is long or dense, the wider deck can still leave a thicker layer, so lighter, repeated passes may be needed. Mulching depends on deck performance and airflow.
Lawn Size and Collection
A 46 cm cutting width indicates the amount of grass the mower can cover in one pass, which affects mowing time and how practical it is to keep edges tidy. For larger gardens, a wider deck reduces the number of passes required, so mowing can be planned in fewer rounds. For smaller or narrow lawns, the wider deck can still be used, but tighter turns may need slower, more careful paths to avoid missed stripes. Before collecting clippings, the lawn area should be estimated, as thicker growth builds up faster. Mulching also changes the collection approach, because clippings are reprocessed rather than bagged.
Ease of Use and Storage
Ease of use matters most on a petrol lawnmower, because it affects how quickly a homeowner can start, manoeuvre, and finish the job. The lawn mower model is built as a self-propelled petrol lawnmower with foldable handles, so it is easier to push across uneven ground and easier to store in a shed or garage. In typical use, the operator should fold the handles fully before lifting or placing the mower, then set it down upright to keep the deck accessible. The 3.5 HP 4-stroke engine and easy start help reduce delays, though heavier weight may still require careful handling.
Who Is This Lawn Mower For?
Who is the Hyundai / 18 inch petrol lawnmower for? It suits people who prefer petrol power, want a medium 46cm cutting width for typical UK gardens, and need mulching to return clippings to the lawn. The 3.5HP 4-stroke engine is designed to deliver stronger performance than small handheld units, while the self-propelled design reduces the effort required when pushing. Foldable handles also make it easier to store in sheds or garages where space is limited. It may not suit buyers who want battery-only operation, or those with very small lawns where the mower's size is harder to manage.
Where to Buy in the UK
Where to buy in the UK matters because the lawn mower cm / 18" self-propelled petrol lawnmower is a specific petrol model, and availability can vary by retailer and stock. Typically, shoppers find it through well-known garden machinery shops and large online retailers that carry The Hyundai 46cm ranges, though exact listings change. Before ordering, they should check the product title details match, especially the 46 cm cutting width and the 3.5 HP 4-stroke engine, since mismatches happen. They should also confirm the "self-propelled" and "mulching" features, and read the warranty terms.
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 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 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 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.
Is the Hyundai 46cm 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 this lawn mower collect or mulch the grass?
The Hyundai offers mulching, chopping clippings finely and dropping them back to feed the lawn - no emptying, though it suits regular light cuts. Many mowers also collect into a grass box if you prefer a clean finish.
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 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.
