The HYM40Li420SP is a rechargeable low-maintenance lithium-ion battery-powered lawn mower from Hyundai which is ideally suited to small to medium sized lawns bringing you a clean, green, cable-free mowing experience. Self-propulsion takes the hard work out of mowing by actually pushing the machine along to reduce fatigue so so you can simply walk behind to control its path. 

No Cables, No Petrol, No Pollution - the HYM40Li420SP lawn mower is powered by the market-leading Samsung 40v Lithium-ion 2.5Ah batteries, no more messy fuel or dangerous mains cables.

With a charging time of just 80 minutes, and a battery lifespan of 1000+ charges, the HYM40Li420P makes mowing your lawn as easy as possible and will provide 30 minutes of continuous cutting time under normal operating conditions. The battery has an indicator light allowing you to see exactly how much life is left.

The HYM40Li420SP mower uses a powerful 40V motor to power the 42cm steel cutter deck. Starting the mower couldn’t be easier, you simply have to insert the safety key, engage the lock-out button and pull back the Operator Presence Control lever. This easy starting method removes the strain associated with recoil pull start lawn mowers.

It also features a spacious quick release 45 litre easy air flow grass catcher with hard lid, meaning you spend less time emptying the cuttings and more time mowing. Attaching and removing the grass collection bag couldn’t be simpler.

With six centrally-adjusted cutting heights, ranging from 25mm for a smooth lawn to 75mm for cutting longer grass, the HYM40Li420SP puts you in control over the finish of your lawn. The mower also comes with a mulch plug to provide a feed for the lawn and eliminate the need to empty the grass bag.

The handles fold down over the main power unit, which makes this compact lawn mower easy to carry and store in a garden shed, garage and transport in the boot of your car. The machine can also stand upright for a compact storage solution when space is limited.

The Hyundai HYM40Li420SP is quick and easy to assemble out of the box, allowing you to get it in your garden for the first cut in no time at all. With no engine to service, you also don’t need to spend time checking oil, air filters or spark plugs, making it extremely easy to maintain.

One battery powers the entire Hyundai 40V range, enabling you to buy bare units of additional machines at reduced cost and interchange the battery for a cost-effective collection of garden tools.
