10 reviews for Hyundai 15″/38cm Cordless 40v Lithium-Ion Battery Roller Lawnmower with Battery and Charger, 5 Adjustable Cutting Heights, 40l

  1. JBB – Worcestershire

    Good small mower for frequent mowing of small to medium sized lawn.Handle assembly was a little tricky, but once we understood how the fittings worked, no problem! Love it’s manoeuvrability, that it’s lightweight, that I don’t have to worry about a cable and that it’s easy to clean. However, it is not good on really damp long grass – would suggest setting cutting height to high and accept that one will have to recharge battery during cutting. Battery lasts about 20 minutes so I have to be efficient if I want to cut the lawn using only one charge – will be considering buying a second battery for next years mowing season to enable me to cut the front lawn as well which, because we are a corner property, I normally use my petrol mower for.

    For the price, great valueThis is a good lightweight mower, however it really needs a more powerful battery as if you have a slightly larger lawn or even 2 small onesI doubt that the battery will last. However if you keep your grass short and only cut when dry, you should be OK.I find that I use position 3 on the cut height, if the grass is slightly long, and then go over it on position 2, it’s still 50/50 whether or not I can do it on one charge though and I have a small, very flat, lawn. It really needs a 60v battery instead of the 40.It is very easy to put together and the handle collapses to make it easy to store. However when the handle collapses it hooks over the height control lever and normally moves it from your last position, you have to remember this when you next use it. Also with the handle down it’s hard to use the mowers carry handle, something that should have been sorted in its design stage.

    Not as powerful as a mains lawnmowerAfter unpacking the mower I found that the power cable for charging was missing, Contacted Hyundai and they are putting the part in the post for me, As it came with a nearly fully charged battery I decided to cut my lawn. First impressions were it is light and easy to handle, The blade I thought could be a little sharper as it was not giving a really clean cut, but that is a simple thing to rectify. Comparing it with my old Bosch mains lawnmower, it does not pickup the cuttings as well, and it struggles a bit on the 20 mm cut, But having said that my lawn is on a bit of a slope. I bought this mower because I wanted something light and easy to handle without the danger of cutting a mains cable. It is more than satisfactory for that, and a bonus it folds up nice and compact for storage. I can only give it a 4 star because of the blunt blade and not great at picking up cuttings.

    Doesn’t cut to edge and battery runtime shorter than expectedI have a large garden and I have been maintaining the lawn with a Hayter Harrier 56cm which weighs in at 58.5kg before the 80l grass box fills up. This said I purchased the Hyundai battery mower specifically to cut around the edges and fiddly bits. I chose this Hyundai for two features , firstly it is one of the shorter cuts 20mm as I need it to blend with the Hayter that cuts down to 13mm. Secondly was the back roller to prevent scalping when mowing over flowerbed edges. My overall impression is that this is a good well built mower for the price, and I do not regret my purchase. It is light and maneuverable and grass box is about right size for lifting when full . This said following is my list of niggles and issues.1/ The battery life is not as long as expected being only about 20min instead of 30.2/ Due to short battery life I have been trying to purchase a spare and they seem to be in short supply at the moment and they are more expensive than other manufacturers equivalent capacity batteries.3/ Due to the double wall nature of the plastic deck the mower doesn’t cut very close to the edge4/ Due to mulching blade it doesn’t always pick up leaves as well as I would like, particularly on the lowest setting. Set wheels higher and it sucks better and then the full indicator flap on the grass box also starts to work.5/ Takes about 2.5 times longer to charge the battery than to discharge it.6/ There seems to be no spare blades available for this mower yet, I presume it is too new, I have outstanding ticket with Hyundai to locate one. I hope a highlift blade will be option.7/ If you want stripes the roller is not much good as the height is not controlled with the wheel height adjustment. It is spring-loaded so the full weight of the machine is not on it. On the lowest setting there is more push in the spring and seems to work ok to prevent scalping on edges.8/ The blade is either made of softer metal or is thinner than the Hayter one so seems to dent and blunt more easily when you catch the occasional stone.

    Great buyLightweight easy to use and effective. Only criticism that the blade height setting are spaced too far apart. Easy to use, quick to charge.

  6. Peter

    cuts well but needs a second batterySturdy and easy to use. Not the lightest machine but not too heavy either. However, the battery is insufficient for me to cut both the front and back lawns on one charge (small front lawn and half as much again larger at the rear). This machine should be supplied with 2 batteries. Cuts well though.

  7. Amazon Customer

    Not bad but awful batteryWhen it works it does a pretty reasonable job – unfortunately the battery doesn’t last five minutes. I would say we have a very small front garden and a small/medium sized rear garden. Have to change 3 times to complete. Additional battery is circa £90 so rather than buy a battery bought a corded mower instead!

  8. MR J E PUGH

    RecommendedEasy to assemble, light weight, quiet cuts well and collects the grass Appears to do everything you’d need.Chargers quick. Recommended

    Easy to use but doesn’t like uneven groundEasy to assemble but a little lightweight on uneven ground

    What once was hate is now a love affair…Oh how I HATED to mow the lawn with the typical (I’m sure everyone’s purchased one at one point) orange flymo ‘only hovers when you’re lobbing it up the lawn’ mowers… what a pain that was!So lots of reading and consideration and I settled on this one – my parents have a Hyundai petrol mower with that self propel thing and it’s awesome!This is easy to assemble out the box just tighten the handles and pop the box on the back.To clarify the description – it DOES come with a mulching plug.Charge the battery up, pop it in, turn the dial and off you go!Has adjustable heights (easy to adjust) and isn’t overly noisy – I’ve tried mulching and mowing into the collector.If I had to say any negatives? It doesn’t like the shortest cutting height and/or mulching on particularly mossy areas (i’m sure the same for other brands though) and the handles were a little tricky to tighten in place where they join the machine.Would definitely purchase again. The booklet says the battery will take 1000 charges – even at 1 mow a week that’s the next 20 years sorted!
