Small To Medium Sized Lawns

The HYM400P is low maintenance petrol powered rotary lawnmower from Hyundai. A “no fuss” lawnmower ideally suited for small to medium-sized lawns up to approx. 20m x 20m, the HYM400P has a cutting width of 400mm and is powered by a 79cc 4-stroke OHV petrol engine, delivering impressive cutting power, but also low levels of noise and fuel consumption to minimise disruption and keep running costs to a minimum.

Easy Start

HYM400P easy start machine, with the option to place the recoil cord at the top of the handle which eliminates the need to bend down when starting it.

6 Cutting Heights

Single point height adjuster for all 4 wheels. With six cutting heights controlled from a central height adjustment lever ranges from 25mm for a smooth lawn to 75mm for cutting longer grass, the HYM400P puts you in control over the finish of your cut.

Ultimate Durability

With the lightweight and very durable polypropylene deck, your mower will remain free from rust and corrosion.

User Friendly

It’s quick and easy to assemble out of the box, allowing you to be mowing in no time at all, and with low servicing requirements, it will provide years of reliable service.

40L Grass Collector

With a spacious quick release 40L polyester grass catcher bag, you will spend less time emptying the cuttings and more time mowing. Attaching and removing the collection bag couldn’t be simpler, and this allows you to dispose of the cuttings quickly and conveniently.

Maximum Comfort

For increased comfort, this petrol lawnmower features a soft grip handle, which reduces fatigue when used for long periods.

Ultimate Safety

The OPC (Operator Presence Control) lever will ensure that the engine will not run if you let go of the handle.

Compact Design

The handles also fold down over the main power unit, which makes this compact lawn mower easy to store in a garden shed, garage or even a vehicle.

Ultra Lightweight Petrol 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 maximise manoeuvrability. It also means it can be lifted into the car boot with relative ease.

    Excellent value for money and well made

    Posted by BR, Leicestershire on 18th Feb 2021

    I bought this mower to replace a Honda which had given many years of faithful service. I was first attracted to the price which was significantly cheaper but having taken delivery (very speedy) and assembled it, I am very impressed by the build quality and easy starting. I had one query on assembly which the technical team were able to assist with over the phone. Overall, I am very happy with my purchase.

    Excellent lightweight petrol mower

    Posted by AD, Luton on 14th Sep 2020

    Bought this to replace my old Briggs & Stratton powered mower which was rusting apart. Fast delivery, starts easily, cuts well. Only slight negatives are it's a little under-powered (only noticeable when trying to cut long grass) and the grass collection box is quite small so fills up quickly. I had a problem with hot starting, quickly resolved by customer services.

    Sweet as a nut!

    I originally bought an electric mower from elsewhere, however before I opened the box my son encouraged me to return it and purchase a petrol mower instead to avoid all the hassle with cables, we searched around and were going to purchase one for around £200 from a different manufacturer that had a steel deck, however we came across this one at the last minute which has a very small engine and a light polypropylene deck. The mower is great starts really easily after a few pumps on the red button, and collects the grass efficiently without blocking up. We’ve only used the mower about three times so far, but so far so good. Would recommend if you’re looking for a small light patrol mower at a reasonable price.

    This mower is excellent for the money, great service so far! Delivery was well fast and so far it seems like a very good product and well designed. (although the handle arms where they move against each other when folding/unfolding cause a nasty scratch in the nice glossy paintwork) Good work Hyundai!

    Lawnmower perfect, delivery service terrible

    Posted by BS, Carlisle on 1st Aug 2020

    Fantastic lawnmower, good quality, easy to assamble, not too noisy and good priced, really easy starting engine. Delivery ? Nightmare, it took 18 days to deliver it, and I had to contact customer service for them to order another one for me as the first one was supposedly lost somewhere

    Order was delivered in 2 working days. Delighted with the quality and overall experience of dealing with you.I had a query regarding some ambiguity in the safety instructions but the customer service team responded very quickly to my satisfaction. Machine has been excellent in use.
