5. Why do I need different heights on my lawnmower?
You should change the height you cut your lawn depending on the season. 

  • Spring (March / April / May) - Mow once a week on a high to medium height setting.
  • Summer (June / July / August) - Mow twice a week under good growing conditions on a low setting. You should mow once a week in a medium to high setting in dry conditions.

11. Can this mower go backwards?
Yes. Pull the mower backwards to move in tight spaces.

12. Is the engine low emissions?
All of our petrol lawnmowers are powered by Hyundai OHV 4-Stroke Euro 5 engines. These are low emission and extremely economical petrol engines. Our engines are all easy starting and have low fuel consumption. This means the running costs are low. They are also low maintenance.

16. I am elderly and would like a mower I can start with no fuss or trouble - which one will be best for me?
All of our mowers are easy starting. The easiest to start would be one of our push button electric start mowers. You will be able to start your mower with the touch of a button. They still have a recoil pull start as a backup.

17. Do I need to buy the mulching plug and side discharge chute?
No. These are included with your lawnmower so you can use them right away.

18. What is mulching and what are the benefits of it?
Mulching is great for your lawn. The grass being cut is chopped into fine pieces and are deposited back into your lawn. This allows valuable nutrients to enter the soil. You will save time and effort by not having to empty the grass bag and you will also save money on artificial fertilisers (mulching is a great alternative to chemical fertilisers). Your lawn will be healthy and attractive. Mulching will also improve the moisture retention of your lawn so you will not have to water it as often.

Excellent All Round
The price was reasonable, delivery was fast and putting it together was easy apart from there being no explanation of how to use the two small plastic lugs in the parts bag, which from another review seems to be something to do with holding the rear flap up a little for some reason. I am looking forward to its first use once we have a dry enough day!
Review by DSH Buxton / (Posted on 04/10/2019)
electric start mower

Review by GAD Cheshire / (Posted on 02/10/2019)
Hyundai 520spe
Fast Delivery and easy to assemble, put oil in petrol in charged the battery no priming started first time. if you are wondering what the extra plastic lugs are for if you have one fo these mowers they are to lift the the rear flap, so that If your are cutting and not collecting the exit for the grass does not get blocked . The lugs fit under the rear flap either side of the kinge,

Excellent product A1+++++++++++++++

Great mower, great quality
Arrived in one day, great service, very easy to set up, started first pull and first electric start. Grass looks smart, very easy to use on our multi level lawns....very happy.
Review by PAC Crowborough, East Sussex / (Posted on 01/09/2019)
Wonderful machine, best mower I have ever used BUT what a silly cup holder. Seems like a leftover from a 1975 car. Sorry but it spoils a superb machine. And I mean a superb machine. You will never find better.
Review by E.T. Hatfield Peverel, Essex. / (Posted on 31/08/2019)
good lawnmower
assembled easily out of the box, though i am by no means a "handyman". Poor but adequate instructions. No list of parts.
Worked fine at first push button. only time will tell how good it really is

HYM510SPE lawn mower
Great machine, good delivery, well made, excellent electric start. Used today to cut all of our large lawn, completed much faster than previous machine due to 20" cut and electric starts after each box full, Bonus, with electric start my wife can use it !
Review by J.M. Rayleigh Essex. / (Posted on 15/07/2019)
Unbeatable at this price!
Received (quickly) yesterday and quick to put together. Looks solid and easily powerful enough for my needs. Love the variable speed, easy start and height adjustment. Really impressed and sure it'll last. A keeper.
Review by FW, Suffolk / (Posted on 02/07/2019)
Fantastic mower, poor instructions, cheap plastics
As a mower, this thing is wonderful. The torque in the drive wheels means it drags me up the lawn incline instead of being pushed. The grass is mulched into fine pieces which fill every corner of the large collector. This combined with the cutting width has allowed me to fly through my large, inclined, tree and feature-filled back garden in only an hour, when with a Honda HR173 it felt like it took all afternoon and most of my life force.

The pull cord start is very easy to use to start the mower, my wife can easily manage it, and the electric start is also very efficient.

It appears to be decently fuel-efficient.

I would definitely recommend this mower, however, the negatives to be aware of:

I wouldn't mind an alternator as plugging a huge mower into the mains to charge it isn't the easiest.

The mower itself is extremely heavy so beware it takes two people to get it out of the box unless you're going to pull the box apart.

Some of the plastics feel like they will not stand the test of time, being a little flimsy.

The exposed pull cord makes mowing under low trees, alongside bushes a little impractical.

The instructions are pretty terrible when it comes to basic assembly and getting started. Before I bought the mower I watched a great YouTube video from the manufacturer on how to put it together, and low and behold what I received was not how his started, with bolts in a bag, not holding the handle in place etc. Not a huge deal, but if you're going to bother making a video to make up for poor instructions, it might as well be accurate to the delivered product.

All in all, definitely worth it and as others have said I wished I bought this sooner.
Review by MFP, Brigg, North Lincolnshire / (Posted on 02/07/2019)
Ticks all the boxes for me
I have difficulties walking and most lawn mowers are beyond my physical limits. I tried HYM510SPE that a friend had bought and it was just like pushing a shopping trolley around ASDA (infact it was easier with its self drive and 4 speed option - I restricted myself to the slowest speed).

This bit of machinery is so easy to use. I no longer have to fork out for a gardener to cut my lawn.

Even my wife loves the two cup holders built into the handle assembly.

It is only the first day after doing the final assembly on the patio. So I cannot give a long term opinion. But initial feelings are that this is quality equipment and I would expect to get many years cutting my lawn, whilst getting exercise and not watching others doing it for me.

Mine is a medium sized lawn. The HYM510SPE is well suited to large areas for sure. But the advantage of using a big machine/wide cutting path for me is that I have much fewer rows to cut making it within my limits.

Many thanks Hyundai.

fantastic mower
I am more than happy with my new lawnmower. I have never spent this much on a mower before but it is completely worth it. I read lots of good reviews and thought it was a very decent price for the hyundai brand. Easily the best one I've owned, so far so good. Thankyou!
