Cordless Lawn Mower For Small / Medium Lawns

The HYM40LI380P is a rechargeable low-maintenance lithium-ion battery-powered 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.

Battery Lawn Mower

The HYM40LI380P mower features a powerful 40v motor and comes complete with a 40v battery and charger. The battery also has a handy indicator light allowing you to see exactly how much battery life is remaining. 

With a charging time of just 80 minutes and a battery lifespan of 1000+ charges, the HYM40LI380P makes mowing your lawn as easy as possible and will provide an average mowing time of 20 minutes from one charge, depending on the operating conditions.

Rear Roller Mower

This compact mower is fitted with a full width ribbed rear roller for creating a traditional striped British lawn that would even rival Wembley Stadium.

380mm Cutting Width

With an cutting width of 380mm / 15", this mower is ideal for small to medium-sized lawns and gardens.

For the perfect, tailored cut on your lawn, the HYM40LI380P can be easily adjusted between its 5 different cutting heights - ranging from 20mm for a super smooth lawn to a 70mm 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 HYM40LI380P's spacious 40L 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.

Push Lawn Mower

Weighing just 13.9kg, this cordless, battery-powered mower is really easy to push around your garden. This is essential for hand push models to minimise any strain or discomfort on your arms or shoulders.

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 Lawn Mower

Thanks to its incredibly quiet-running motor, the HYM40LI380P is an ultra-quiet lawn mower to minimise any disturbances to your neighbours or family.

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. It also features upright legs for a compact vertical storage solution when space is limited.

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.

What Are the Benefits of a Cordless Mower?

No cables, no petrol and no pollution - the eco-friendly HYM40LI380P 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.

Off to mow a meadow

Fantastic buy. Simple to put together and operate.

Simpson Seng

I'm delighted with the mower

Christian Morris
Good mower

This product is lightweight and easy to use once the battery has been charged a few times to reach full capacity. It is not as powerful or long-lasting as my older EGO 480mm model, but it is smaller and much more manoeuvrable, which is why I chose it. There are a couple of improvements that could be made: the handles should be able to lock in the folded position and the height-adjusting lever is prone to being knocked into a lower position by low-hanging branches - a double-lock system may be necessary. Despite this, I am pleased with the product and would recommend it.

Hyundai cordless mower

We ordered this mower and delivery was great - it arrived on time as expected. Assembly was a breeze and, even though it's fairly new to us, it's been really simple to use. Much lighter than my previous corded mower, it's cut our grass-cutting time by almost 50%. I'd highly recommend this mower and the website used for ordering

Hyundai cordless mower

I'm thrilled with my new Hyundai 40v lawnmower. Much better than my last Bosch electric mower.
