Petrol Lawn Mower For Medium Gardens

The HYM460SP is a low-maintenance, self-propelled petrol lawn mower from Hyundai, providing an extremely economical powerful performance for mowing medium-sized lawns.

The Hyundai HYM460SP lawn mower is powered by an impressive Hyundai 139cc / 3.7hp OHV economical petrol 4-stroke engine for quick and efficient cutting.

Self-Propelled Lawn Mower

With rear wheel drive, which is especially good for handling uneven terrain, this mower also features a self-propelled system where all you have to do is hold on and steer - no pushing required! Mowing has never been easier. The drive to the rear wheels is controlled from the rear-mounted handle control.

460mm Cutting Width

With a cutting width of 460mm / 18", this mower is ideal for medium-sized lawns and gardens.

For the perfect, tailored cut on your lawn, the HYM460SP can be easily adjusted between its 6 different cutting heights - from 25mm to 75mm - by using a single height adjusting lever, giving you complete control over your lawn care needs.

The HYM460SP's spacious, extra-large grass collector bag, featuring a high airflow plastic top with a level indicator to ensure maximum grass pickup, ensures that you'll spend less time having to empty the cuttings, reducing your overall mowing time. This mower also comes with a mulching plug and a side discharge chute for multiple grass clipping options.

Safe and Easy To Use

Designed with your safety in mind, the HYM460SP includes OPC (Operator Presence Control) technology that ensures the engine will not run if you let go of the handle.

With minimal assembly required and 600ml engine oil included, you can be up and running in minutes to get that first cut on your lawn done as quickly as possible!

The soft grip handles can be folded forwards oven the main body for extra-compact storage to save space in your garden shed or garage. This powerful mower's deck also features a garden hose connector to make cleaning underneath the lawn mower as simple and hassle-free as possible.

Janice Stableford
Very good buy and quick delivery

My previous mower had stopped working and my lawn was in desperate need of a cut, so I was delighted when this one arrived within two days. It was simple to assemble and came with the oil already included. Amazingly, it started with just one pull and handled my overgrown grass with ease - much less effort than my previous mower. I would definitely recommend it.

Zoe Thompson

Quickly dispatched following purchase. Simple assembly. Powerful cutting ability. Ample collection bin.

Caroline Bingham
Great overall machine

I replaced my Mountfield machine with the HYM460SP. The build quality is much better and the controls are simpler to use, as is the engine noise which is quieter. The delivery was swift, taking only two days and I was kept up to date with emails on the progress. Assembling the machine was straightforward, thanks to the U Tube video, and it started up first time. The only minor issue is that it is slightly heavier than my old mower, but it is still easy to manoeuvre, so this is not an issue.

Paul Henry
Quality Mower

Outstanding results for the cost. Always starts up. Cuts through anything. Exceptional mulching ability.

Neil Jordan
Amazing product

Replacing our well-used Mountfield (20 years!) we researched many lawnmower reviews and this one came out on top. Assembly was a breeze, starting with one pull, and it copes well with our large garden. We can't fault it and the grass looks great. I feel you get what you pay for with this petrol mower and, although some may think the price is high, I'm confident it will last as long as the last one.
