  1. Dr. Keith A. Moseley

    I ordered this mower following several favourable reviews. Most important for me was the push button start. While I can pull a cord (and this mower does have one as back up) it is a pain to have to keep doing this if one is going to mow scattered sections around a large site, moving the mower, powered down so the blades are stopped, between. To my delight, the machine started up first time with the choke and every time without the choke afterwards. The fuel consumption is frugal, the noise level acceptable and the vibration minimal. Of course, fuel stabiliser added to the petrol is essential for four stroke garden tools if you don’t want the carburettor gummed up. The ‘dead man’s handle’ is easy to use as is the drive engagement control; both are broad horizontal bars gripped to the handle. The mower has four driven speeds and is reasonably light enough to just be pushed, if necessary. The height adjuster must be spring-loaded because the deck is easy to raise. The cut is good although, at the lowest setting, it won’t achieve cricket pitch perfection like my other mower. I found the instructions straightforward although I was left with two small black plastic bits until I realised that they fitted the back of the mower to hold the flap out when mulch mowing. I haven’t tried that yet although the plastic bits can be left in place even if the grass box is on. The grass box is easy to empty, having a flat unobstructed bottom. If there was one thing I would change it would be to have a roller at the back instead of two wheels, not because I want stripes but because the mower, at it lowest cut height, can ground itself on uneven bits of the lawn. It is quite a sight seeing the powered rear wheels spinning in the air. However, a powered roller would result in a radical redesign of the grass chute at the rear so fair enough.

    After 10 years tackling a very large uneven lawn my high end wide bladed Hayter mower finally bit the dust last Autumn, so I’ve been on the lookout for a similar replacement. The Hayter was built like a tank but had a pull chord start that took some pulling and at 63 I was hoping to be able to afford an electric start mower. Most large blade self propelled electric start mowers cost a fortune and were well beyond my budget.This Hyundai ticked all the boxes and was an incredibly reasonable price so I hesitated for ages, thinking it was likely to be a bad purchase. I couldn’t have been more wrong!It arrived within a couple of days in a well packed carton. It says it comes without oil and you need to buy a bottle, but in fact there’s a separate bottle of mower oil supplied in the carton. I should also mention that there has been some negative review comments about the guarantee, but you no longer need to fill in a form within 30 days, their website confirms your purchase is your guarantee (see screengrab attached).The mower was incredibly easy to put together, all you need to do is attach the handle mechanism with a few bolts, add the cup holder (a piece of genius bling!) with a couple of screws, hook on the two cables, add oil and fuel, and you’re ready to go. From opening box to start up and mow was about 20 mins.The mower is actually incredibly very well built and sturdy, and it looks fantastic. It’s recommended you charge the small starter battery (mains charging lead supplied) for 6 hours but mine fired up first time straight out of the box.All the settings and controls are very light and easy to use. Unless you’re mowing Wimbledon I wouldn’t recommend the lowest setting, as it really is tight to the ground and won’t forgive any humps or dips. Level 2 is perfect, even for a first cut. On the speed side I’d also avoid the top speed (4), as this really jumps forward with a bit of a kick, but (3) is perfect for a smart pace across the lawn.As you can see from the before and after pictures I have a very large undulating lawn that actually has several crests and levels to it. The old Hayter used to stick on the slopes but this beauty just whizzed over everything without a blip. As it was the first cut of the year after a long mowerless autumn and winter, I decided to save endless grass bag emptyings and put the mulching plug in instead. The Hayter was a mulcher but it still used to dump unsightly clumps all over the place. This machine didn’t leave a trace of grass and the mulched material was very fine. I’d recommend mulching as it’s the right eco-thing to do and with this mower I’ll stick with it as empty bags is a chore.Coming back to the cup holder I thought this was just a gimmick but it also came into its own when I was at the far end of the garden!The final piece of brilliance on this machine is the little hose attachment nozzle on the topside. I didn’t think this was serious, but I followed the instructions, connected my garden hose to it, turned the water on full blast, and started up the mower. To my amazement the machine cleaned itself! One of the worst aspects of cutting the lawn with my old heavy mower was trying to turn it on its side afterwards to brush off the cack, without the oil or the petrol all spilling out. 10/10 Hyundai for this brilliant idea.Oh, yes, the start button also cleverly pops out so you can prevent curious kids from starting it up.I’ve now had the machine for a fortnight and have cut the grass four times with it. The results are amazing and it’s an absolute pleasure to use. I’d recommend this machine to anyone with a larger than average lawn who needs a very well priced, robust and easy to operate mower.FEBRUARY 2023 UPDATEI cleaned the mower carefully and gave the battery a full charge last November before putting this mower away in a clean, dry garden shed for the winter. Pulled it out this morning, filled it with petrol, checked the oil (fine) pressed the start button, and off she went first time. My large lawn was already pretty thick with new, fresh growth, a badger had dug loads of holes and there were old leaves everywhere but this incredible machine just blasted through it all (see last two pix).. It mulches really fine so I got a great improver for the lawn from all the leaves it pulped. At the end of the run the lawn was pretty even and perfect. All I’ll need to do in a few days time when the mulching clumps have gone, is a quick, light trim and we’re ready for the summer. Once again the machine cleaned really easily with a hose nozzle on blast – the plastic parts are very non-stick, and the self cleaning facility is amazing. My only very tiny niggle was that the nozzle for attaching your garden hose to the mower is a bit stiff, so I solved this by cutting an 2ft length of garden hose with connectors each end. I leave one end permanently attached to the mower and just stash the length of hose by the basket when the mower’s in use. A power clean takes about 5 mins and leaves the underside pretty perfect. I’m also impressed that nothing has so far shown signs of rust or tarnish. Best £450 I ever spent!!

    We bought this to replace a Wolf BMC Racer and whist this was more expensive, it is a beast! Delivered much earlier than additionally stated, easy to assemble, clear instructions, wide cutting blade, started first time, plenty of speed choices and height of cut choices and cuts right up to edges due to well designed position of wheels. What’s not to like. I highly recommend this mower.

  4. Jmax

    Very pleased with this lawnmower. Perfect size for my 3/4 acre garden. Easy to start with the electric starter, and so far I’ve started it 22 times on one charge and still loads of power left in the battery. Goes up the slopes with ease and very low use on fuel, it’s not as noisey as I thought it would be and I don’t need ear guards as it’s a nice low pitch sound unlike 2 stroke engines. Does a great job and also looks really stylish and modern.I recommend this to anyone with a large garden and slopes. Great work Hyundai.Update 19/04/2019Just to let you all know this is still going strong and running great, best lawnmower I’ve owned and well worth buying. No issues at all.Update 8/9/2020Been using this for 2 years now and it’s still going strong. No problems at all and preforms like a champ. Just wanted to update to show it’s reliability and I’m still very impressed. Worth it’s money without a doubt.Update 4/4/2021My lawnmower is now coming upto 3 years old and still going strong. Kept in the shed when not used and still looks like new, no rust or problems what so ever. Starts first time every time and really is worth every penny. It’s a beast that wants to live on and on.Still recommend by me.Update 9/4/2022Out comes this beast again for the 4th year and still going strong, only thing I’ve had to do is change the oil and sharpen the blades, other than that it starts first time and runs perfectly, stored in a shed each winter with no sign of rust. I feel this will go on for many years to come. Best purchase ever 👍🏻

    Bought this mower for the electric start feature. My 10 year old pull start mower was on its last legs, as are my ageing shoulders so getting it started was difficult. The push button start is a game changer – petrol and oil in, started first time out of the box with no priming necessary. It also has a pull start as backup.It’s a heavy mower – especially if you haven’t used a petrol one before but it’s also self propelled with four speed settings so you don’t notice the weight. Start on speed 1 though and build up! It was on top speed out of the box and it takes off like a bat out of hell! Fine if you’re expecting it, though, and you’ll get the job done quicker.It also came with 600ml of oil which is the mower’s exact capacity.The only thing I didn’t like was that I can’t take the starter battery off to charge it in the house. Luckily I have sockets in the garage, but if you don’t then bear this in mind.If this gives me a decade of service like the old Qualcast did, I’ll be happy.

    After using a sit on mower for 18 years decided to buy a push mower. I did a lot of research and eventually decided on this machine (I do also have 2 other Big Brand push mowers but never felt the Briggs&Stratton 149cc on both of those machines was strong enough). This machine though with a 196cc Hyundai engine is awesome, its a big wide cut & it has a bit of weight behind it but I don’t see that as an issue as the the power to manoeuvre is always there. The electric start is a god send, it comes with a simple plug in charger which easily charges up the battery. The build quality is very good, assembly took 15 minutes & with the supplied oil and fresh 4star fuel we was up and running in no time. Due to the sizes of my 3 lawns I have never been one for fine low cuts, I did try all the levels but the higher level 3 out of 4 suits my grass best – I don’t use my lawn for bowling. The dB noise level is less than the Briggs&Stratton 149cc which is pleasing to the ears & neighbours. The 2 drink holders are handy when u plan to be out for a fair bit of time. I found this machine as good alternative to the sit on mower and hope I get many years of service out of it.

    My lawn took a battering over summer 2022 in the UK, due to the hot weather and kids. I decided to renovate it and realised the old Flymo wasn’t going to be suitable – mainly because you can’t accurately control the cut height. I chose this particular Hyundai model for the height control, width of cut, self propulsion, variable drive speed and electric start (it does start also start easily on a single pull of the cord too). The photos are taken 4 weeks apart – keeping the cut height around 2 inches has improved the health of the lawn and it looks great. The mower doesn’t have a rear roller but still produces faint stripes. I got stronger striping by adding a Toro striping roller, which sits behind the grass box. Time will tell if the mower remains reliable – so far it’s been perfect. On the downside, it’s very heavy! 40+ kg means it would be very difficult to use in a terraced garden or anywhere you had to lift it.

    Really easy to put together and a dream to use.Started first time and does a perfect job much more quickly than my older machine.To say we are pleased with it is an understatement.We have quite a large lawn and this mower will be the perfect machine to do the job.

    After reading the reviews I purchased this mower as it has the electric start option so my wife can start it should she wish. It does self charge if you are giving it long enough running to charge between starts. But you can also pull start and that is much easier once the mower is already warmed up. This is a heavy machine to manoeuvre in tight spaces but with the 20″ cut it’s not designed for small lawns. My grass had grown very long so I set the cut height to max and the speed to 2 and used the side shoot and no grass box with the slower speed it allows the mower to cope even with this very long grass. The speed 4 is quite fast unless you have a long straight run so going back and forward with turns would be 2/3 mostly. Building was very simple as it’s fairly basic just a few bolts and engaging the cables into the handles add the supplied oil and away you go .I have only had this for a week but on my first couple of uses I would recommend it

    Like all blokes I dream about having a sit-on mower and having moved to a new house with a decent sized garden here was my chance. But, Ilwhen comparing the highest rated self-propelled mowers vs the sit-one I just couldn’t justify the £1200 price difference. So home comes this Hyundai. It better be good! Out of the box at a little heavy at first – but this is my first petrol mower so allow me some adjustment. It comes largely pre-built so just a few bits to bolt together, pretty straight forward although the instructions are not the most unambiguous I’ve ever seen. Spark plug located, oil in, petrol in, let’s go. But wait, I need to charge the battery for 5hrs first! This will p**s on my parade. Oh well I’ll have press the start button and pretend. However the battery was charged already (despite the instructions assuring me if wouldn’t be’. So off I went – a happy cutter. The 4 speed adjustment is great, I was able to slow it right down while I operated under L-Plate conditions and then as I got all teenage and cocky I unleashed top gear. It’s quite fast, as could be seen by the shredded plants lying murdered in the flower bed where I’d gone off-road. I had a bit of left/right lever coordination to perfect. But, I’ll be whizzing around the garden by next summer. The cutting height is more than adequate – I ended up raising it to about the midpoint for an autumn cut with lots of leaves provided a challenge the machine was more than man enough for. One observation, the grass collector is big. This is great for a lasy so and so like me however it does weigh the reaper down even more and I t will leave wheel indents in your lawn that hang around for a few days. This is good but f you want to perfect you straight plough lines and quite like the effect.So a very new and pleasant experience. Time will tell if my infatuation turns into the real thing and our relationship blossoms in the spring however early signs are promising.
