DESCRIPTION

Cordless Lawn Mower For Small / Medium Lawns

The HYM40LI420SP is a rechargeable low-maintenance lithium-ion battery-powered self-propelled lawn mower from Hyundai. The ideal battery-powered lawn mower for small to medium-sized lawns, this mower will bring you a clean, green, cable-free mowing experience.

Self-Propelled Petrol Mower

This battery-powered mower also features a self-propelled system - no pushing required! Mowing has never been easier.

Battery Lawn Mower

The HYM40LI420SP mower features a powerful 40v motor and comes complete with a 40v battery and charger. The battery has a handy indicator light allowing you to see exactly how much battery life is remaining. There is also a spare battery compartment within the mower that allows you to store a fully charged spare battery (sold separately) so you can swap batteries if required.

With a charging time of just 80 minutes and a battery lifespan of 1000+ charges, the HYM40LI420SP makes mowing your lawn as easy as possible and will provide an average mowing time of 15 minutes from one charge, depending on the operating conditions.

420mm Cutting Width

With an cutting width of 420mm / 16.5", this mower is ideal for small to medium-sized lawns and gardens.

For the perfect, tailored cut on your lawn, the HYM40LI420SP can be easily adjusted between its 6 different cutting heights - ranging from 25mm for a super smooth lawn to a 75mm option if you’re trimming rougher ground or doing a first cut - by using a single height adjusting lever, giving you complete control over your lawn care needs.

The HYM40LI420SP's spacious 45L grass collector bag, featuring a high airflow and hard lid, ensures that you'll spend less time having to empty the cuttings and thus reducing your overall mowing time.

This cordless lawn mower comes with a mulching plug option, where your dropped cuttings become compost, creating a healthier-looking, lush, green lawn.

Lightweight Lawn Mower

Weighing just 19.9kg, this cordless, battery-powered mower is really easy to move around your garden.

Using this powerful mower couldn’t be easier - simply insert the safety key, engage the lock-out button and pull back the OPC (Operator Presence Control) lever. This easy-starting method removes any of the strain associated with petrol recoil pull-start lawn mowers.

Compact and Quiet

Thanks to its incredibly quiet-running motor, the HYM40LI420SP is an ultra-quiet lawn mower to minimise any disturbances to your neighbours or family.

It’s 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.

This lawn mower is so compact to store and transport. Thanks to its clever design, its handles fold down over the main power unit, which saves space in your garden shed or garage. On top of this, it is also able to be stood upright for a compact storage solution when space is limited.

What Are the Benefits of a Cordless Mower?

No cables, no petrol and no pollution - the HYM40LI420SP lawnmower is powered by a market-leading 40v lithium-ion 2.5Ah battery, which means no more messy fuel to have to deal with and no dangerous mains cables - mowing the lawn has never been easier or safer.

3 Year Warranty

Very quick delivery

I placed this order on Friday and it was delivered by DPD on Saturday. Even an elderly person could assemble it easily. Unfortunately, I haven't been able to use it yet as the grass is too wet, but it appears to be a good purchase.

Pleased with it

Received this morning and just mowed the grass - all seems good. Easy to assemble. Battery lasted well - mowed all my grass with juice to spare. Light to move around and easy to change cutting height. Glad I bought it!

Great machine

I was delighted to use the website for the first time yesterday and have my mower delivered the next day. It was a great first cut as the mower went at a gentle pace for an elderly user and the grass was packed nicely into the collector. I'm still undecided on buying a spare battery as they seem quite pricey, not sure if my battery or I will run out of energy first! All in all, I'm very pleased with my purchase.

Lawnmower cordless self drive

Ordered on Tuesday, delivered on Wednesday, and the grass was cut shortly after - amazing service! The machine is great and the battery was only half used after cutting over 200m of grass - I'm very pleased with it so far.

HYUNDAI 42CM CORDLESS 40V LITHIUM-ION BATTERY SELF-PROPELLED LAWNMOWER

Delivered on time and easy to assemble, only requiring the handle to be attached. Have only used it once so far, but it cut the lawn effectively. It was quicker than my old mower, thanks to its wider cut, and the self-propelled feature was a great help.
