Hyundai HYM430SP Petrol Lawn Mower

The Hyundai HYM430SP Self-Propelled Petrol Lawn Mower with rear-wheel drive, ideal for small to medium-sized lawns.

Powerful and Economical Engine

The HYM430SP is powered by a Hyundai 139cc 3HP OHV 4-stroke petrol engine, providing ample power to mow your lawn quickly and effectively. The contactless ignition system means the engine is effortless to start, allowing you to get mowing straight away.

Self-Propelled and Rear-Wheel Drive

This lawnmower is self-propelled, meaning that it drives itself forward – all you have to do is steer! – ensuring a stress and strain-free mowing experience. The drive to the rear wheels is controlled from the rear-mounted handle control, which provides extra traction to make it easier to mow uneven lawns. All of the mower’s wheels use twin sealed bearings for long life and low resistance.

Get the Perfect Cut on Your Lawn

Fitted with a hard-wearing powder-coated steel deck for long life, this petrol mower’s cutting width of 430mm/17” is suited to small or medium gardens and will get the job done quickly and achieve a precise cut each and every time.

Adjustable Cutting Heights

The cutting height can easily be adjusted to six different heights (between 25mm and 75mm) by using the single height adjusting lever, allowing you to tailor the finish of your lawn.

Grass Collection Options

The large quick-release 45-litre grass collector features a high airflow plastic top to ensure maximum grass pickup. You can also use the supplied mulching plug to give your lawn a nutritious feed with the cuttings – this also means less time spent emptying the grass collector.

Safe and Easy to Use

Built with safety in mind, the HYM430SP comes with OPC (Operator Presence Control) technology, ensuring that the engine will not run if you let go of the handle.

Compact Design for Storage

For extra compact storage, the lawnmower handles can fold down, ideal for saving space in your garage, garden shed or when transporting the mower in your car or van.

Quick and Easy Assembly

With tool-free assembly, you can be up and running out of the box in minutes.

Peace of Mind

All Hyundai lawn mowers are covered by a Hyundai 3 year platinum warranty.
