Hyundai Petrol Lawnmower Review UK 2026

Key specifications

Mower Type and Power

This lawn mower inch / 42 cm petrol lawn mower is a petrol push unit powered by a 139cc petrol engine. It is designed for mowing where power is needed without relying on a cable. As a push model, it suits level to mildly uneven gardens, because the user provides the forward movement while the engine supplies the cutting power. The 139cc petrol engine size indicates suitability for routine grass growth, although heavy, long, or very wet grass may require slower passes and extra attention. It uses an electric-start approach, which can make starting easier.

Cutting Width and Deck

With a 42 cm cutting width (17"), the Hyundai petrol mower covers a fairly wide strip in each pass, which can help reduce mowing time on medium-sized lawns. A 42 cm deck suits many everyday garden layouts, since it can move through straight runs efficiently. However, wider decks can feel less nimble around tight borders, trees and fence corners, so extra trimming may still be needed with a strimmer or smaller passes. The mower's deck size also affects how evenly grass is handled, since the blade must clear the full width at the same height setting.

Lawn Size and Collection

A 42 cm cutting width means the lawn mower petrol lawnmower can cover a useful strip per pass, making it suitable for medium-sized lawns where mowing time matters. For smaller gardens, the mower can still be used, although tighter turns may require additional passes. For larger areas, the 139cc petrol engine can help maintain consistent progress, but the operator still needs to plan routes to avoid missed patches and repeated tracks. Grass collection affects convenience as well, since dense grass and uneven growth can slow emptying. For best results, mowing can be done in sections, with planned overlaps.

Ease of Use and Storage

Getting started and stored away is an important part of using the Hyundai, particularly because it has a 139cc petrol engine and an electric-start system, which can make first use quicker than pull-start models. After mowing, the 42cm deck design still needs careful handling when the machine is tilted for cleaning and when it is set down. Storage is easier if the mower's height suits common shed spaces, but the deck and other parts can still take time to manage. The electric-start reduces the amount of effort needed to begin mowing, but petrol handling also requires safe fuel storage, and the engine should be allowed to cool before indoor storage.

Who Is This Lawn Mower For?

The lawn mower (42cm) 139cc electric-start self-propelled petrol lawnmower is for people who want petrol power with easier starting than pull-start models. It suits users who regularly mow average-sized lawns, with a 42cm cutting width designed to cover ground efficiently without pushing effort on larger areas.
