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 up to 60 minutes from one charge, depending on the operating conditions*

Run Time (No Load) - Up to 60mins
Run Time (Light/Dry Conditions) - Up to 40mins
Run Time (Heavy/Wet Conditions - Up to 20mins

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.

3 Year Warranty

    Hyundai cordless mower

    Posted by David Beach on 7th May 2022

    We ordered this mower and delivery was good, prompt and arrived at the time expected. Really simple to put together and although this is still quite a new mower to us this has been really easy to use. Much lighter than my old corded mower and has reduced the time it takes to cut our grass by almost 50%. Definitely recommend this mower and this website for ordering. Information was clear from the site and gave good updates on status.

    Good mower

    Posted by RJA Essex on 5th May 2021

    It's light and quick to use, once the battery has been charged a couple of times to bring it to full capacity. It doesn't have quite the power and endurance of my older EGO 480mm job, but then it's smaller and much lighter and manoevrable (which is why I bought it). A couple of improvement suggestions: provide for the handles to lock in the folded position and the height adjusting lever is a bit susceptible to being knocked into too low a position by overhanging low branches - a double lock provision needed perhaps. Generally satisfied with it and happy to give it my recommendation.

    Very happy with the mower, does my small lawn easily on one charge. If your grass has grown long cut it on a high setting first then go again on the lower setting, that way it has no problems.

    Hyundai cordless mower

    Posted by FD on 6th Aug 2020

    Very happy with my new Hyundai 40v lawnmower. It has plenty of power and is effortless to use.I can mow the front and back lawns on one charge of the battery. A big improvement to my old electric Bosch lawn mower.
