The Hyundai lawn mower stands out as a 196cc petrol engine with electric start, self-propelled drive, and a 51cm cutting width. It suits users who want faster passes on average lawns, as the six cutting heights support different grass conditions.

Mower Type and Power
Petrol-powered self-propelled lawn mowing is handled by the lawn mower inch / 51 cm 196 cc petrol lawnmower. It is designed to cut grass across a 51 cm cutting width per pass. The self-propelled drive supports forward movement, which can help reduce effort on longer, uneven ground. It also offers multiple cutting heights, with 6 set levels, so users can adjust the cut for different grass conditions.
Cutting Width and Deck
The Hyundai inch 51 cm 196cc electric-start self-propelled petrol lawnmower is set up for a 51 cm cutting width, meaning each pass covers a fairly wide strip of lawn. This wider deck can reduce the number of overlaps when mowing, especially along straight runs, while awkward edges still require careful turning. The deck offers 6 cutting heights, allowing the operator to match the blade height to grass conditions rather than relying on one fixed setting. A 51 cm deck can also make pushing through narrower pathways more difficult because the mower remains broad.
Lawn Size and Collection
A 51 cm cutting width determines the lawn area covered per pass, but collection capacity affects how often the operator needs to stop. The lawn mower petrol mower uses a grass box collector with a 70 l capacity, so it is suited to medium to larger gardens where emptying is less frequent. For smaller lawns, the 51 cm width can still be effective, although corners and edges typically require shorter passes. When mowing longer grass, the clippings fill the box faster, so more trips to empty the collector are expected. Six cutting heights provide control over grass cutting, helping manage buildup and reduce rework.
Ease of Use and Storage
Ease of use is shaped by the mower's self-propelled petrol design and its handling features, because the operator can move the machine forward with less pushing effort, while still controlling the cut by setting one of the six cutting heights. The 51cm cutting width helps cover ground in fewer passes, and the 70l grass collector reduces how often collection stops are needed, although this depends on grass volume. For storage, the foldable handles support easier placement in sheds or garages, and the 20-inch class format is typically easier to manoeuvre around tight spaces. Some weight remains, so careful lifting is required.
Who Is This Lawn Mower For?
This lawn mower petrol lawnmower is aimed at homeowners looking for a self-propelled petrol machine for regular garden mowing. The 51cm cutting width helps reduce the number of passes, which suits people with mid-sized lawns who want a single mower for routine use. The 196cc petrol engine and electric-start setup provide quicker readiness, and the 70-litre grass collector is designed to reduce how often the bin needs emptying. Six cutting heights suit lawns that require changes in cut length across seasons or areas where growth is slightly different. For very small gardens where storage space and easy manoeuvring matter more than cut width, it may be less suitable.

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 51cm 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 51cm 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 20?
The lawn mower runs on a 196cc 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 20 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.
