I’ve cut two lawns (approx 80m) twice and haven’t had to recharge which is good. No more messing with cables getting caught on the shrubbery!!
The lowest cut isn’t as low as the previous mower but the lawn still looks great when done. Shouldn’t cut the lawn too short in the summer anyway.
On the whole I’m happy with the mower. Although I still have concerns over the longevity of the batteries
Now the not so good:
Assembly was straightforward but installation of safety features was not.
Not as manouverable as my old power mower which weighed 5 kg more – mainly due to the wheels being a tad small.
Some of the plastic parts look a little flimsy – time will tell.
Overall a pretty competent mower which with care should last many years – I hope.
The actual machine I purchased HYM40Li420P, is a joy to operate, the cut, its abilities and ease of operation including the batteries etc, all without a hitch, FIRST CLASS piece of kit and good value.
Cuts well and love the different levels of height adjustment. A lot more powerful than other cordless ones I have tried. Battery lasts more or less whole grass but will buy a 2nd battery for future.
Like the space age look of the battery compartment and the sturdy build. Perhaps it is my fault, but I thought it ran on two batteries, whereas one of the two compartments is just to store a second one that is not supplied. I am 5 foot eleven inches and although I constructed the handles in the high position it is not high enough for me, which means you have to stoop somewhat to push it. I can’t see any way to modify it.
All in all it is rather disappointing but I will have to persevere with it.
Overall happy with the purchase. It’s very quite I must admit (I’m sure the neighbours appreciate that).
It’s also easy to adjust cutting height. Machine looks great and feels well built. The only down part is that it only comes with 1 battery which for me means charging twice to complete my 180ft garden. Now looking to buy a 2nd battery
After the last useless mower decide to blow up; I wanted something more reliable. I wasn’t sure at first at the idea of a battery powered mower, but now I’ll never look back.
Last longer than the suggested 15 minute window
Easy to assemble
Strong and easy to manoeuvre
Various settings and delivers an excellent cut
No longer have to wrestle the cords, and pray that a tough patch of grass isn’t going go rip it’s motor apart.
Cuts well and has plenty of power. Cuts my medium sized front and back lawns twice in one charge.
Would have given it 5 stars apart from:
1. The instructions say that the battery should be fully discharged before recharging. As it comes with only one battery this makes things awkward. When I contacted their representative they said they’d offer me a 5% discount on another battery making it still over 100. When I contacted them again they then said that the instructions are out of date and that the new battery doesn’t need to be discharged. Hope that’s the truth.
2. Really needs to be able to cut a bit lower as my lawn still looks like it could do with a bit more off after I’ve finished.
I note other reviews have said this, so if you prefer a short cut lawn look elsewhere.
3. The plastic hubcaps keep coming off, which is disappointing as the rest of the machine feels so well built.
This is a review after 5 months. I had a couple of issues. Solved instantly without BS by Amazon.
Hyundai is like a Honda but made in Korea. Built well. It won’t go wrong unless you misuse it. It’s the best of Korea for machinery like Samsung is for electronics. Like Mitsubishi is for machinery in Japan and Sony is for electronics. Same deal. You can’t go wrong. It will do the job to the highest quality. It cuts grass. Exactly as designed.
This is the budget best for medium sized lawns. No heavy steel roller so you don’t wow lines like a cricket ground. But you get two go’s on one charge. It has staying power. But that will recede with age obviously. A new battery is a new life after a couple of years I reckon.
Bottom line. The best economy buy.
Really impressed with build quality and cutting performance. Ideal for my medium size lawn.
A good purchase and very happy so far.
A touch heavy due to metal frame but does the job well.
Battery charging is slick and efficient
Good value for money
This is easy to use nice and light and maneuverable. Cuts the grass with ease. Will not like very long grass. Battery last quite a time. Room for second battery but you will have to buy it only one battery supplyed. Recommend this machine.
Arrived within the stated times and was well packaged. Easy to assemble and use, but does rattle a bit. Battery charging is quite quick. The height adjustment lever can catch on walls and bushes.
Just used this mower for the first time, easy to put together and very pleasant to start and use. Did find that on our medium sized garden as the grass had grown pretty long since our last mower died with the sun and rain, it took 2 charges of the battery to cut all the grass. I’m sure now just keeping it trim will be achievable on a single change but I’ll buy a 2nd battery anyway just for peace of mind.
Excellent Hyundai 42 cm cordless mower replacing 35 year old Mountfield 45 cm petrol mower. Much lighter and easier to use than the Mountfield and a lot easier to start of course. Looks reasonably well made as well but whether it will last 35 years is another matter, but I won’t anyway so it’s academic. Running cost is zero as I have solar panels. The only concern was battery life but it cuts my 100 square metre lawn dropping only one led from 4 to 3 so is probably good for 2 or maybe 3 suts before recharging. I did consider buying a Moutfield cordless but at almost twice the price I think I made the right choice.
It was easy to assemble. The lawn looked good after I mowed it.
Most importantly no more messing about with a cable.
Knocked a star off because it is a bit plastic looking.
However, there’s a few things that need improvement.
– It’s very heavy. 20kg is a lot for a lawn mower that’s meant for personal use.
– Folding the machine as shown in the photos requires that you loosen one triangle screw and remove another one after every use. This part definitely requires improvement as it takes a lot of space if not folded.
– Instructions were not accurate but after contacting Hyundai I was told the manual was for the previous model. Kudos to their support for the prompt response.
Was nervous about buying this as I’ve been used to petrol mowers with a 45cm blade. Battery life is very good, 250sq m lawn cut in 35 mins with 2 lights still showing on battery.
Have just received this, took me longer to read the safety notes esp about battery use, than it took to assemble.
Much lighter to use than my petrol mower, sliced through long damp grass with ease on the trial run. Waiting to see how it performs on a full lawn cut and how long the battery lasts.
So, I have cut 2 big lawns and 3 smaller ones on one battery charge. Impressed. The grass box takes a lot of clippings, about 30% more than my Honda.
The height adjustments and quality of the cut are better than my old mower, and the battery life is significantly longer than I need – I didn’t even move off of all four LED lights being lit, I assume indicating that I didn’t go below 75%.
The only minor annoyances for me were how the assembly diagram didn’t exactly match the device in real life – the thumb screws have to go on the outside near the body to permit the grass box to be attached, and also that the handle can’t be double-folded without completely removing the lower screws/bolts each time. It would have been nice if some alternative method of securing the lower part of the handle could have been employed to allow simpler full folding each time.
I purchased this after I burnt out my electric mower cutting a neighbours overgrown lawn. I wanted something substantial and boy this is substantial. It is made of steel so as you would expect it is quite heavy, but the wheels cope with that on the lawn surface. The height adjustment is easy to use and just slides into place, so when moving from front to back lawns, I just slot it into the highest notch and then reset when ready to mow. I only purchased this in October last year, just ready for the final cut of the year. I was impressed, but waited to review after a couple of cuts this year. Well, spring sprung early, and I have trimmed the lawns a couple of times and the mower does a great job. The battery has loads of power left when I have finished. I would recommend this mower to friends or family.
So easy to assemble and get going. Cuts lovely and it cut relatively large lawn with life still in battery.
Easy to assemble and operate.Not to noisy.
No trailing cord to contend with.
Only down side is having only one battery which lasts about 15mins.88 for another battery if you can find any in stock.
Extremely pleased with this mower – only used once as yet but very easy to operate, lighter than expected which is a bonus to me. Plenty of battery life left after a complete cut of my med/large lawn.
The main thing to point out is that the mower is very well built, very sturdy and very heavy. Easy to push, it glides along the lawn mulching as it cuts ( once the mulching plug is assembled).
Our 112ft x 20ft wide garden used just over half of a full charge.
I would highly recommend this mower, with the proviso that the weight might be a problem.
Seems to be well made and robust, looks good, easily assembled and easy to use. Also great colour.
has enough battery power for the average medium sized lawn.
Easy to use good power and looks grea
The battery provided more than enough charge to cut both the front and rear lawn – circa 100 square metres – and the grass was wet and quite long.
Last but not least, the quality of the cut was excellent. Really pleased with this mower.
