Cordless Lawn Mower For Small / Medium Lawns
The HYM40LI420P 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 HYM40LI420P 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 HYM40LI420P 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 HYM40LI420P 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 HYM40LI420P'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.
Push Lawn Mower
Weighing just 19.9kg, 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 HYM40LI420P 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. On top of this, it is also able to be stood upright for a compact 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 HYM40LI420P 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.
