Full Description

Budget-Friendly Petrol Lawn Mower

The HYM400P is a low-maintenance, compact petrol lawn mower from Hyundai. Fitted with a lightweight and very durable polypropylene deck, it is the most budget-friendly option of all of our petrol lawn mowers.

The Hyundai HYM400P lawn mower is powered by an impressive Hyundai 79cc OHV economical petrol 4-stroke engine, delivering impressive cutting power but also low levels of noise and fuel consumption to minimise disruption and keep running costs to a minimum. It also features a soft-pull recoil start for easy starting each time.

400mm Cutting Width

With a cutting width of 400mm / 16″, this mower is ideal for small to medium lawns and gardens.

For the perfect, tailored cut on your lawn, the HYM400P can be easily adjusted between its 6 different cutting heights – from 25mm for super smooth 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 HYM400P’s spacious 40L polyester grass collector bag ensures that you’ll spend less time having to empty the cuttings, reducing your overall mowing time.

Push Lawn Mower

Weighing just 19kg, this is one of the lightest petrol lawnmowers on the market, which is essential for hand push models to minimise fatigue and any strain on your arms and shoulders. It also means it can be lifted into the car boot with relative ease.

The soft grip handles can be folded forwards oven the main body for extra-compact storage to save space in your garden shed or garage.

Safe and Easy To Use

Designed with your safety in mind, the HYM400P includes OPC (Operator Presence Control) technology that ensures the engine will not run if you let go of the handle.

With minimal assembly required and 600ml engine oil included, you can be up and running in minutes to get that first cut on your lawn done as quickly as possible!

  1. sally barton

    ReliabilityThis item was sturdy but light to use

  2. Mrs L Norris

    Mower for short peoplePretty easy to put together given a box spanner no idea why. Found the handle low to push had to crouch obviously the mower is for a Hobbit. That said seems OK I would say its feels a little fragile pushing if but seems to do the job

  3. MRF

    As advertisedNot strong enough.

  4. Aethelbald

    Good Machine but Rubbish InstructionThree sets of instructions in mine, none of them first class and all of them containing differences. So not a good start and I had to call for help. One thing not mentioned in any of the instructions {as I recall}, is the little plastic flap bar that you have to hold over when clipping on the grass catcher bag. Doing that turns it from shockingly bad to excellent. There is also a strange device for holding the starter cord on the handle. Could not fathom the utility of this and ignoring is fine. The dead man’s grip works well but the cable is too long and gets in the way sometimes. The DMG function is excellent. All in all a good machine poorly presented.

    Good engine but awful grass collectionI like this mower a lot as its always easy to start, although the throttle is just on or off, no in between (low power/high power). The biggest gripe I have is the grass collection. Well before the collection bag is even half full it seems to clog up at the back of the mower and I have to take the bag off and unblock the hole where the grass is ejected. I had a Mountfield before this and it had a plastic “ejector chute” which stopped that from happening. I don’t know if this mower is supposed to have the same thing but I never saw it in the box if it did. Even without the collection bag it clogs up (and yes, I’m cutting DRY grass).I bought this because of the brand and apart from the collection headache I actually like it. I just hope it lasts a decent amount of time.

    If anything, it’s too good !!I got one of these a few months ago and wanted to use if a few times before leaving a review.The lawnmower is delivered partially built, but, in all honesty all you need to do is attach the handles to the motor unit, fit the wheels, put some oil in (not included in the package), fill with petrol and you’re good to go. I’d read some stories about trouble starting it, but, I’ve had no issues at all. Each time I use it I press the RED button on the front 5 times, pull the starting cord about 3 times and it’s off. Plus I didn’t have adjust the starter cable, it worked straight away.The reason I wanted a petrol mower was because my electric mower was ok as long at the grass was very dry. As soon as there was any moisture on the grass, the electric mower would struggle and leave clumps of wet grass everywhere. This is not a problem at all with this mower!! My first run was on wet grass which was about 2.5 inches high and there were no clumps left at all, this mower just picked it all up.The reason I have titled the review ‘If anything, it’s too good’ is because the grass collector fills up after I’ve done two lines up/down the garden so there is quite a lot of stopping/starting the mower to empty the collector.This mower is also great for picking up leaves. I put it on the highest height setting and do quick run over the garden and all the leaves are gone.All in all a great mower.

    Easy set up and good lawn mowerEasy set up. Good lawn mower, one of the lightest on the market, but still feels heavy. Good number of mower settings.

  8. Julian Foulger

    Just the jobWhy did I purchase this mower? Well, I have a small, sloping front garden. My lawnmower that I use for my large back garden is awkward to manoeuvre on such terrain and I have to carry it through 2 gates and up several steps. In the past I have had an expensive Honda Izzy and an Atco mower. Both mowers had steel decks which rusted away in 4-5 years due to mowing my lawn when it was wet; I live in Cumbria, say no more! The deck on this Hyundai is polycarbonate and is a substantial thickness so no rust issues there. It starts first time on the pull chord and is very quiet. The only assembly needed on receipt was to fit 2 pieces of the handle into place and tighten a screw each side then insert the top part of the handle and the knobs to raise and lower it. Who needs instructions for that? I’ve used it twice and it does a perfect cut. Don’t be put off by the low price and think you won’t get quality. This is a great little mower.

    Great machine so far – handles abit low for average adultMachine works well after 1 use so far, easy to assemble – started at first pull after pressing red starter button about 5-6 times – although instructions were a waste of time! Follow you tube review videos..My only criticism at this point is the handle bars are at quite a low angle – comes up to just above waist, I’m 5ft 10 so after using for 20min I did feel a bit of back pain from leaning forward – it should be lifted at a slightly higher angle for ease of use..

  10. Daniel Lowe

    HEAVY!!! NO NEED FOR GYM AFTERWARDSMachine is too heavy to push. Not smooth at all. On the plus side, it was easy to build.
