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!

3 Year Warranty

As with all of our Hyundai Lawn Mower range, the HYM400P comes with our Hyundai 3 year home-use warranty* and 1 year commercial warranty* (terms apply) for added peace of mind.

    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!

    Posted by Nance on 13th Sep 2020

    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.
